Dear Governor and Legislative Leaders:
As requested by the Joint Legislative Audit Committee, the Bureau of State Audits presents its audit report on the
Department of Transportation’s (Caltrans) Toll Bridge Seismic Retrofit Program (program). The report examines
the cost increases for the program between its budget established in 2001 and its August 2004 cost estimate, as
well as Caltrans’ project management practices for the program.
This report concludes that the $3.2 billion increase in estimated program costs and the four-year time delay
in the program occurred for many reasons, but the replacement of the San Francisco-Oakland Bay Bridge’s
east span (East Span) was the largest contributor, with an estimated cost increase of $2.5 billion. However,
only $930 million of the $3.2 billion cost increase relates to the bid for the superstructure of the East Span’s
signature span; the remainder is attributable to increases for other cost categories such as Caltrans’ support costs
and the program contingency reserve, which rose by $556 million and $452 million, respectively. According to
Caltrans, costs may rise even further as the contract to construct the superstructure for the East Span’s signature
span has expired and Caltrans must now either rebid or redesign this section of the bridge.
Despite the East Span’s extraordinary strategic, technical, and financial risks, Caltrans failed to create a risk
management plan, track risks that it identified, or update its cost estimates and contingency reserve to reflect
those risks. Further, Caltrans’ cost update for the August 2004 report to the Legislature was its first program-wide
update of cost estimates since April 2001. Finally, as early as November 2003, when it reported the program’s
financial status to the Federal Highway Administration, Caltrans should have known that the program would
experience large cost overruns. At that time, Caltrans failed to recognize that it had only a year and a half of
support costs funding remaining though the program was to last eight more years, that the bid for the signature
span’s superstructure would be much higher than its official estimate, and that its remaining program contingency
reserve of $122 million was inadequate given the uncertainty facing the program.
Respectfully submitted,
ELAINE M. HOWLE

a consistently high level of diligence in applying accepted
project management practices. However, Caltrans has not
fully incorporated generally accepted standards for project
management. This report considers Caltrans’ efforts in
managing project risk, cost, and communications—areas in
which it could have guided the program better to achieve the
maximum chance of success. In the area of risk management,
22 California State Auditor Report 2004-140 California State Auditor Report 2004-140 33
the report focuses on the East Span, which accounts for
$2.5 billion of the $3.2 billion in cost overruns and the
four-year delay. Although Caltrans took steps to identify
and mitigate risks to the East Span project, such as hiring
consultants to perform a risk assessment in February 2003, it
lacked a comprehensive risk management plan for the East Span.
Without a risk management plan, Caltrans never defined its risk
management activities for the program. As a result, Caltrans
lacked processes to identify, track, and quantify risks throughout
the project’s life.
In managing the project’s cost, Caltrans has not followed
generally accepted cost management practices to ensure
that the project could be completed within its 2001 budget,
approved by the Legislature in AB 1171. Caltrans did not
regularly update its cost estimates for some components
of the East Span or the entire program, including updating
estimates for capital and support costs. Also, Caltrans did not
use information about identified risks to regularly reassess
its contingency reserves for potential claims and unknown
risks. For example, Caltrans indicated to the Federal Highway
Administration (FHWA) in February 2004 that its program
support costs would be $766 million, $30 million less than the
AB 1171 estimated amount. However, Caltrans’ accounting
records show that it already had spent $612 million in support
costs by October 2003, leaving only $154 million to pay such
costs for eight more years, through 2011. Just six months
later, in August 2004, it raised its estimated support costs to
$1.352 billion. Without updated cost estimates, Caltrans’
program managers forgo the benefits of a detailed overview
of the program’s capital and support costs for all the bridges.
Further, Caltrans indicates that since October 2001, when
AB 1171 was passed, its only published program-wide cost
update was the August 2004 report, which disclosed the
$3.2 billion cost overrun. Had it been monitoring the program’s
costs regularly, Caltrans would have realized much earlier that
the program was exceeding its budget under AB 1171.
Finally, Caltrans has neglected communications planning and
management, failing to inform significant stakeholders regularly
of relevant changes in its estimates of program costs and cost
overruns. State law requires Caltrans to provide periodic status
reports to the Legislature, but Caltrans provided no statutorily
required annual status report for 2003 and no statutorily required
quarterly status report in 2004 until August of that year. It chose
not to disclose program information according to the regular
22 California State Auditor Report 2004-140 California State Auditor Report 2004-140 33
reporting schedule established by law and disclosed the large
cost overruns long after it should have known that the program
likely would exceed its budget. As a consequence, Caltrans
placed the Legislature in the awkward position of having to try
to devise a funding solution six weeks before the bid on the
signature span’s superstructure was set to expire.
In November 2003, Caltrans submitted a legally required
financial plan update to FHWA showing that the program’s
projects were going beyond the AB 1171 cost levels and that
less than a 3 percent program contingency reserve remained—
$122 million—to fund further cost overruns in the eight years
left to complete the project. In response to FHWA’s questions
about the financial plan, Caltrans did not reveal the probable
extent of estimated program costs: at the time of the report,
Caltrans’ internal analyses showed that it would likely exceed
the AB 1171 budget. Based on internal Caltrans’ reports
and the amounts it eventually reported to the Legislature in
August 2004, Caltrans should have known about the huge cost
overruns. For example, although Caltrans had advertised the
contract for the signature span’s superstructure at $733 million,
internal analyses showed that as early as August 2002 this
contract could be as high as $934 million, while later estimates
placed its potential price at more than $1 billion. Further, the
uncommitted balance of $122 million in the contingency
reserve was grossly insufficient given that Caltrans had not
received the superstructure bid, the East Span’s skyway was only
31 percent constructed, and the Richmond-San Rafael Bridge
retrofit costs were underreported by $43 million to $78 million.
In fact, in its report to FHWA, Caltrans claimed it would save
$130 million in three areas, thus allowing it to assert that it
had a program contingency reserve of $122 million. However,
by August 2004, Caltrans reported for those same three areas
(unrelated to the capital costs of the superstructure bid) that
it would not save $130 million from AB 1171 estimates and
that it would need $748 million more than AB 1171 estimates
for a total of $878 million more than it reported to FHWA just
six months earlier.
RECOMMENDATIONS
To ensure that it properly manages the risks associated with large
construction projects, Caltrans should continue to revise its risk
management practices, but ensure that its efforts include:
44 California State Auditor Report 2004-140 California State Auditor Report 2004-140 55
• Establishing a comprehensive risk management plan that
clearly defines roles and responsibilities for risk management
and addresses how it will identify and quantify project risks,
implement and track risk response activities, and monitor and
control risks throughout the life of the project.
• Quantifying the effect of identified risks in financial terms.
• Developing and maintaining documents to track identified
risks and related mitigation steps.
To ensure that it follows generally accepted practices for cost
management, Caltrans should:
• Regularly update its estimates of capital and support costs.
• Regularly reassess its reserves for potential claims and unknown
risks, incorporating information related to risks identified and
quantified through its risk assessment processes.
• Regularly integrate estimates for capital, support costs, and
contingency reserves into a program-wide report.
To ensure that it keeps its stakeholders informed on the status of
projects, Caltrans should:
• Submit quarterly status reports to the Legislature, as the
law requires.
• Ensure that reports to FHWA and other stakeholders reflect
current data and provide an accurate representation of the
program’s status.
• When key events occur, such as a bid opening for a major
project, quickly inform stakeholders how these key events
affect the program’s overall budget and schedule.
The Legislature should consider revising state law to require that
Caltrans submit its quarterly reports within a certain period after
each quarter, such as 45 days, to ensure that the information
that Caltrans provides is current. The Legislature should also
consider changing state law to require that the quarterly reports
provide a program-wide summary of the program’s budget status
for both capital outlay and support costs.
44 California State Auditor Report 2004-140 California State Auditor Report 2004-140 55
In reviewing the options that Caltrans presents for completing
the East Span, the Legislature should consider requesting that
Caltrans provide sufficient detail to understand the financial
implications of each option. Specifically, this detail should
include for each option a breakdown of the costs for capital
outlay, support, and contingencies at the project and program
level. Further, to place each option in perspective, Caltrans should
provide a reconciliation of each option to the figures it presented
in its August 2004 report to the Legislature.

INTRODUCTION
BACKGROUND
The Department of Transportation (Caltrans) is responsible
for the design, construction, maintenance, and operation
of California’s state highway system. Caltrans is also
responsible for assessing the seismic safety of all publicly
owned bridges, except those outside the state highway system
in Los Angeles and Santa Clara counties. In October 1989,
the Loma Prieta earthquake presented Caltrans with the task
of repairing or replacing damaged highway facilities in the
San Francisco Bay Area (Bay Area). To meet the higher seismic
safety standards established after the Loma Prieta earthquake,
the State created a seismic retrofi t program that required the
retrofi t or replacement of all California’s publicly owned bridges,
including highway overpasses and other structures. The seismic
retrofi t program requires that Caltrans identify the seismic
vulnerability of bridges and develop a retrofi t project to address
structural defi ciencies. Retrofi ts may include, among other things,
reinforcing bridge columns and strengthening bridge footings.
After reviewing all 12,000 state highway bridges, Caltrans
identifi ed 750 single- and multiple-column bridges that
needed seismic retrofi t and were either the most vulnerable to
a seismic event or necessary for emergency response during a
widespread civil disaster. Caltrans also determined that seven
(see text box) of nine state-owned toll bridges needed seismic
retrofi tting; the other two state-owned toll bridges,
Antioch and Dumbarton, did not need retrofi ts
because they were built after the State imposed new

an additional 1,155 bridges that Caltrans identifi ed after
the Northridge earthquake. As of June 2004, Caltrans had
completed retrofi tting 1,137 (or 98 percent) of its phase 2
bridges. Completion of the remaining 18 bridges is not expected
until early 2010 because of the more complex retrofi t and
replacement work needed on a number of these bridges.
THE TOLL BRIDGE SEISMIC RETROFIT PROGRAM PLANS
TO REPLACE THE EAST SPAN OF THE SAN FRANCISCO-
OAKLAND BAY BRIDGE
Caltrans is managing the retrofi t and replacement strategies
for the state-owned toll bridges separately from the above
two phases, under the Toll Bridge Seismic Retrofi t Program
(program). After the Loma Prieta earthquake, Caltrans engaged
two universities, numerous private consulting fi rms, and the
Lawrence Livermore National Laboratory to conduct research
to better understand the toll bridges’ seismic vulnerabilities.
In the last half of the 1990s, Caltrans began preparing retrofi t
strategies for each of the toll bridges, with the exception of the
east span of the San Francisco-Oakland Bay Bridge (East Span),
which Caltrans scheduled for replacement as explained later. As
of August 2004, Caltrans had fi nished seismic retrofi ts for the
Benicia-Martinez, Carquinez, San Diego-Coronado, San Mateo-
Hayward, and Vincent Thomas bridges, leaving only the
Richmond-San Rafael Bridge and the San Francisco-Oakland Bay
Bridge to complete.
Caltrans identifi ed the East Span as necessary for
emergency access and recommended replacing it.

commuters’ risk from a moderate-level earthquake before the
construction of a new East Span, Caltrans completed an interim
retrofit of the existing East Span in June 2000.
Caltrans has decided to reevaluate the Antioch and Dumbarton
bridges, although it earlier had decided that they did not require
seismic retrofits. According to the chief deputy district director
of the program (chief deputy), Caltrans has not conducted any
studies or analyses that indicate these bridges need retrofitting,
nor is it aware of any such studies during the last 15 years.
However, based on the slowly accumulating body of knowledge
on seismic safety, the chief deputy says that Caltrans’ current
plan is to evaluate the need for seismic retrofits using a two-
phase approach. The first phase will involve the testing of
two components of each bridge. If this effort indicates further
testing is warranted, Caltrans plans to pursue a more rigorous
phase of testing in 2005. The chief deputy stated that without
further information Caltrans cannot estimate what seismic
retrofits on the bridges might cost, if they are actually needed.
Rather than use toll bridge seismic retrofit program funds,
Caltrans requested to use Regional Measure 1 (measure 1)
funds from the Bay Area Toll Authority (BATA) to pay for the
initial testing, which is estimated to cost $200,000. However,
in December 2004, BATA told Caltrans that it could not
recommend an allocation of measure 1 funds for this purpose.
A 1997 Law Set the Program’s Budget at $2.6 Billion and
Allowed for the Purchase of East Span Amenities
To finance the $1.1 billion actual cost of retrofitting the phase 1
bridges, Caltrans indicated it drew mostly from various federal
sources, which could not provide sufficient funds for retrofitting
or replacing the phase 2 bridges or the toll bridges. Therefore,
in March 1996 California voters approved the Seismic Retrofit
Bond Act of 1996 authorizing the sale of $2 billion in general-
obligation bonds, with $1.4 billion earmarked for the phase 2
bridges and $650 million for the toll bridges. However, the toll
bridges required substantially more funding, so in 1997 the
Legislature passed Senate Bill 60 (SB 60) allocating an additional
$2 billion, mostly from state highway funds and a newly created
seismic surcharge of $1 per vehicle imposed for passage on all
Bay Area toll bridges (seismic surcharge). SB 60 also allocated
tolls collected on the San Diego-Coronado and Vincent Thomas
bridges to the program. The total cost estimate established in
SB 60 for the program was $2.6 billion.
88 California State Auditor Report 2004-140 California State Auditor Report 2004-140 99
In late 1996, Caltrans completed cost estimates for several
different alternatives for the East Span. It recommended
construction of a concrete “skyway” bridge spanning the
San Francisco Bay between Oakland and Yerba Buena Island.
Caltrans estimated the price tag for this replacement at
$1 billion. Figure 1 shows Caltrans’ recommended design for the
east span of the Bay Bridge.
FIGURE 1

However, the replacement recommended by Caltrans was not
commissioned for construction. As the regional transportation
planning, coordinating, and financing agency for the Bay Area,
the Metropolitan Transportation Commission (commission)
was given the authority under SB 60 to select the new East Span
replacement, including the option of incorporating certain
amenities such as a more expensive bridge design than originally
envisioned and a bicycle/pedestrian path, as long as bridge users
pay for the increase in costs. In June 1998, the commission
exercised its option and selected a bridge design that differed
from Caltrans’ recommendation.
1100 California State Auditor Report 2004-140 California State Auditor Report 2004-140 1111
The Commission Chose a Self-Anchored Suspension
Design for the East Span
The commission’s design was a combination skyway and
self-anchored suspension span known as the signature span.
Although the skyway section was similar to Caltrans’ proposed
design, the signature span was envisioned as a landmark
structure, with a single tower rising 525 feet above sea level.
Figure 2 depicts the commission’s selection for the east span of
the Bay Bridge, including the signature span. The commission
based its decision on a preliminary bridge design and cost
estimates available in May and June 1998, which were prepared
by a joint venture design team under contract to Caltrans. At
the time, Caltrans’ preliminary estimates indicated that the
self-anchored suspension, or signature span, design selected
by the commission would cost more than $1.1 billion, or
$141 million more than the simpler skyway bridge it had
recommended. As SB 60 allowed and intended, the commission
extended the Bay Area toll bridge seismic surcharge, set to expire
no later than January 2008, to January 2010 to pay for the
East Span amenities.

Funds Designated for the Toll Bridge Seismic Retrofit
Program Rose to $5.1 Billion in 2001
In April 2001, Caltrans’ annual report to the Legislature and
governor detailed rising cost estimates and project time delays
for the program. The annual report contained revised cost
estimates and project completion dates, along with explanations
of the anticipated cost increases, showing that the East Span
replacement was the largest contributor to the overall projected
cost increase, with an anticipated rise of $1.3 billion over
SB 60’s initial cost estimate. The Richmond-San Rafael Bridge
was the next largest contributor to the higher estimates, with
$336 million in expected additional costs.
In 2001, in response to Caltrans’ annual report, the Legislature
passed Assemply Bill 1171 (AB 1171) to fund the program’s
cost increases. This legislation allocated an additional $2 billion
in Bay Area seismic surcharge proceeds and federal bridge
funds to the retrofit effort, increasing funding to $5.1 billion,
including a program contingency reserve of $448 million.
AB 1171 allowed the commission to request that the seismic
surcharge be extended to January 2038, subject to the approval
of the director of Caltrans, to raise additional funds to cover the
cost increases and other eligible transportation projects. The
commission requested and received approval for this extension.
Table 1 shows that by June 30, 2004, Caltrans had received
much of the funds designated for the program under AB 1171.
Most of these funds relate to seismic surcharges or the proceeds
of revenue bonds that will be repaid with seismic surcharges.
AB 1171 limited the amount of seismic surcharges that can
be collected for the program to nearly $2.3 billion, plus the
interest that will be paid on the revenue bonds. According
to the August 2003 official statement for the revenue bonds,
interest costs will total $1.3 billion. Because no change has been
made to this provision, no extra toll revenues have been made
available to the program to pay for increased capital costs of the
signature span or any other component of the program. As of
June 30, 2004, the Toll Bridge Seismic Retrofit Account, the fund
that receives toll revenues and pays the majority of program
expenditures, did not have any loans outstanding to or receivables
due from other funds beyond those required to support the
everyday administration of the program.

In 2002, the Bureau of State Audits Raised Concerns About
Further Cost Increases
In August 2002, the Bureau of State Audits issued a report on the
program that identified factors that caused program cost estimates
to increase between SB 60 and AB 1171. The report also noted
that remaining contingency levels indicated that costs could rise
further. Table 2 on the following page briefly describes the report’s
scope and findings. The report had no recommendations.
IN 2004, CALTRANS’ ESTIMATES FOR THE PROGRAM
ROSE TO $8.3 BILLION
On August 16, 2004, Caltrans reported to the Legislature that
project time delays and rising cost estimates had increased
the program’s projected cost to $8.3 billion, an increase of
$3.2 billion over its 2001 estimate in AB 1171 of $5.1 billion.
The East Span, with an anticipated shortfall of $2.5 billion,

TABLE 2
Scope and Findings of the Bureau of State Audits August 2002 Report
Report’s Scope:
Evaluate underlying reasons for delays and higher cost estimates for the program.
Determine the role of Caltrans and the commission in planning, implementing and managing program costs.
Determine whether procedures for modifying cost estimates and completion dates are adequate.
Examine a cost review prepared by a commission-hired consultant to identify projects whose costs were likely to be higher
than Caltrans’ estimates.
Report’s Findings:
Costs increased in part because initial legislation allowed the commission to purchase amenities for the East Span not
originally included by Caltrans.
Costs for the East Span increased because of efforts by the U.S. Navy to impede test drilling and a delay in the environmental
review process.
A few bridges experienced cost increases because of difficulties in estimating costs for underwater work.
Caltrans’ failure to include escalation rates in most of its estimates played a role in the understatement of cost estimates in the
initial legislation.
In 2001, the Bechtel Infrastructure Corporation, a commission-hired consultant, concluded that program costs might be
$250 million to $630 million higher than those reported by Caltrans.
By early 2002, the skyway component of the East Span already had used up a large and disproportionate share of the East
Span’s contingency reserve, indicating that the East Span could experience a funding shortfall.
is the largest contributor to that increase. The other major
increases in estimated costs were a $452 million rise in the
program contingency reserve and $249 million in cost overruns
for the Richmond-San Rafael Bridge. Caltrans stated that the
commission and Bechtel Infrastructure Corporation (Bechtel)
had reviewed the overall program’s estimated cost and had
reached consensus with Caltrans on a funding shortfall of
$3.2 billion, including a $900 million program contingency
reserve. Caltrans attributed the cost increases to a number of
factors, but chief among them were significant changes in
financial, insurance, and bonding markets; higher materials
and labor prices; industry consolidation; and delays resulting
in additional cost escalation and increased support costs. We
further discuss the factors behind cost increases in Chapter 1.
Caltrans observed that the extent and timing of the cost increase
was of particular significance because the consequent funding
shortfall made it impossible to accept a bid for the signature
span’s superstructure, received on May 26, 2004, and due to
expire on September 30, 2004. In its report, Caltrans noted
the funding problem and asked the Legislature to enable the
contract award through a supplement to the program budget. It
did not offer suggestions on a source for this additional funding.
When the Legislature did not approve new funding by the end
1144 California State Auditor Report 2004-140 California State Auditor Report 2004-140 1155
of September 2004, the Business, Transportation and Housing
Agency, the state oversight agency for Caltrans, announced
that the contract bid had expired and that it was considering
rebidding or redesigning the signature span.
SCOPE AND METHODOLOGY
The Joint Legislative Audit Committee (audit committee)
requested that the Bureau of State Audits examine the delays
and higher cost estimates for the program. Specifically, the audit
committee requested that we identify the factors contributing
to additional capital and support cost increases, which of these
factors were unforeseen at the time that the AB 1171 estimates
were prepared, and the extent to which the signature span
design independently contributed to costs increases. It also
asked that we compare the program’s cost increases with those
for other large capital projects managed by Caltrans since
fiscal year 2000–01, and identify the potential scope, cost, and
schedule for any retrofit work Caltrans plans to initiate on
the Antioch and Dumbarton bridges. In addition, the audit
committee requested that we describe the role of Caltrans and
transportation planning agencies in planning, implementing,
and managing program costs, examine Caltrans’ basis for the
program’s schedule, evaluate the adequacy of procedures for
modifying cost estimates and completion dates, and determine
whether Caltrans employs best practices when managing
projects that cost more than $1 billion. Finally, the audit
committee asked us to determine the extent to which cost
increases for the signature span were funded by additional toll
contributions, and whether funds appropriated for the program
were diverted to other uses.
To comply with this request, we reviewed and evaluated the
laws, rules, and regulations associated with the program. Based
on these statutes and various interviews with management,
we determined the roles that Caltrans and local planning
agencies play in planning, implementing, and managing the
program’s costs. As noted in the Introduction, we reviewed
Caltrans’ accounting records to ascertain the extent to which
program costs will be funded by additional toll contributions
and whether funds appropriated for the program were diverted
to other uses. We concluded that no funds had been diverted.
Additionally, we interviewed Caltrans staff and program
management to determine the current status of the seismic
retrofit studies for the Antioch and Dumbarton bridges.
1144 California State Auditor Report 2004-140 California State Auditor Report 2004-140 1155
We compared the cost estimates prepared under AB 1171 and
those supporting Caltrans’ August 2004 report and reviewed the
methodology for estimating capital and support costs. We focused
on the east span of the San Francisco-Oakland Bay Bridge and the
Richmond-San Rafael Bridge because these projects accounted for
99 percent of the cost increases for specific bridges. We analyzed
cost changes on these projects to determine where significant
variances occurred and whether these cost factors were unforeseen
at the time of AB 1171. For estimates of capital and support costs
with significant increases since AB 1171, we interviewed Caltrans
staff and program management and evaluated documentation,
such as construction contracts and associated change orders, to
ascertain the reasons for the increases. Further, we examined the
supporting documentation for Bechtel’s August 2004 cost review of
the program. Additionally, we compared program cost increases
and their causes with those that occurred in similar large projects
managed by Caltrans for BATA’s measure 1 program. Finally, we
reviewed Caltrans’ policies and procedures for preparing cost
estimates, including those that relate to contingency reserves.
We compared Caltrans’ management of the program to project
management best practices as described in the Project Management
Body of Knowledge, FHWA guidance for major projects, and
Caltrans’ internal project management handbooks, focusing on
the management of risk, cost, and communications with external
stakeholders. We focused on the East Span because it accounts
for the majority of the program’s increased cost estimates,
although we addressed several issues that affect other projects
or the program as a whole. We interviewed Caltrans staff and
program managers, and reviewed project documents, analyses,
and cost reviews prepared by Caltrans and its consultants. We also
interviewed and received documentation from staff and managers
of FHWA, the commission, and Bechtel. For risk management, we
evaluated Caltrans’ risk management planning and its processes
for risk identification, quantification, mitigation, and tracking
for the East Span. For cost management, we ascertained whether
Caltrans regularly prepared program-wide estimates of costs and
contingency reserves and kept them updated. Because they have
the potential to increase costs above contracted amounts, we
also reviewed a sample of large contract change orders for several
projects to check for compliance with Caltrans’ procedures. For
external communications, we ascertained whether Caltrans
regularly supplied updated and reasonably accurate reports,
incorporating estimates of project costs and contingency reserves,
of the status of the overall program, to critical stakeholders—the
Legislature, FHWA, and the commission. n

CHAPTER 1
Volatile Markets for Contractor
Services and Materials, Schedule
Delays, and Higher Contingencies
Led to a Large Increase in Estimated
Program Costs
CHAPTER SUMMARY
Various factors have dramatically increased estimated costs
for the Toll Bridge Seismic Retrofit Program (program)
above the $5.1 billion program budget the Legislature
passed in October 2001 as part of Assembly Bill 1171 (AB 1171).
Most of the $3.2 billion program increase that the Department
of Transportation (Caltrans) presented in its August 2004
estimate relates to the replacement of the east span of the
San Francisco-Oakland Bay Bridge (East Span). The uniqueness
of the program has made predicting costs an uncertain endeavor.
Caltrans indicates that never have such complex bridges been
seismically retrofitted, leading a consulting firm hired to
perform a cost review of the program to report that traditional
highway construction measurements do not apply to retrofitting
the East Span. Contributing to the higher cost estimates have
been volatile markets for materials and contractor services,
which have yielded bids that include higher than expected steel
and contractor overhead costs. It is impossible to determine the
impact of certain factors because Caltrans’ standard contract
provisions limit its access to the information supporting
contractors’ bid prices. It may not disclose such information as
it is acknowledged to constitute trade secrets and is not deemed
a public record. Also, Caltrans’ efforts to increase competition
among contractors by extending the bidding period for the
signature span’s superstructure, and its lengthening of the time
allowed for contractors to complete this contract, pushed out
the program’s completion date by four years. This has increased
the period during which Caltrans’ support services for these
projects will be required and generally escalated cost estimates for
future construction contracts. In addition, historical information
from completed toll bridge construction contracts and data from
outstanding contracts led to increased contingency reserves to
cover the cost of known potential risks and unknown risks for
individual projects and the overall program.
1166 California State Auditor Report 2004-140 California State Auditor Report 2004-140 1177
Caltrans’ August 2004 cost estimates were based on accepting a
$1.4 billion bid to construct the signature span’s superstructure.
The bid was allowed to expire, so the beginning of construction
will be delayed further as Caltrans considers redesigning
or rebidding this component. According to Caltrans in its
August 2004 report, failure to accept the bid likely would cause
program costs to rise even further.
RISING COSTS AND DELAYS PLAGUE COMPLETION OF
THE STATE’S LARGEST PUBLIC SAFETY PROJECT
In its August 2004 report to the Legislature on the program’s
status, Caltrans disclosed cost estimates that were $3.2 billion,
or about 63 percent higher, than the estimates it prepared in
Caltrans’ August 2004 April 2001. Caltrans’ 2001 estimates formed the basis for the
cost estimates for the program budget the Legislature adopted in AB 1171. Caltrans’
program were $3.2 billion reevaluation of program costs was triggered in May 2004 by
higher than its estimates receiving the sole bid for the signature span’s superstructure,
in April 2001, including which exceeded Caltrans’ 2001 estimate by $930 million.
$2.5 billion more related After this event, Caltrans requested that the Metropolitan
to the East Span. Transportation Commission (commission) assist in an
overall review of the program. The commission then hired a
consultant to review Caltrans’ estimate of costs to complete
the program. In separate August 2004 reports, Caltrans and
Bechtel Infrastructure Corporation (Bechtel), the commission’s
consultant, agreed on a program cost estimate of $8.3 billion,
including a $900 million program contingency reserve. Table 3
summarizes the differences between the cost estimates in
AB 1171 and Caltrans’ August 2004 cost estimates for each of
the seven state-owned toll bridges being retrofitted or replaced.
As the table shows, the revised cost estimate for individual toll
bridges was about $2.8 billion more than the cost estimates used
for AB 1171, while the estimated program contingency reserve
rose by $452 million. Of these increases, Caltrans estimates that
about $2.5 billion relates to higher costs for the East Span. The
small variances in costs for the last five bridges in the table were
not surprising because these bridges were substantially complete
when Caltrans recalibrated the program budget in 2001.

Most of the Program’s Significant Increase in Cost Estimates
and Program Delays Relate to the East Span
More than 90 percent, or $2.5 billion, of the cost increase for
specific bridges relates to the East Span replacement project,
which has a number of components, including the signature
span, the skyway, and the demolition of the existing bridge.
The commission chose the signature span design to replace
1188 California State Auditor Report 2004-140 California State Auditor Report 2004-140 1199
nearly a quarter of the simpler skyway bridge that Caltrans
originally proposed for the entire distance between Oakland and
Yerba Buena Island. Figures 1 and 2 in the Introduction show
artists’ renderings of these two designs. As Table 3 on page
19 shows, although other East Span components saw increases
in cost estimates between AB 1171 and August 2004, the most
significant was the increase for the signature span, which rose
by more than $1.3 billion, or 162 percent. In contrast, the
skyway component that remained in the East Span design rose
by 61 percent; the remainder of the East Span, composed of
12 components, rose by 73 percent.
In addition, Caltrans’ August 2004 estimates include a
$900 million program contingency reserve. Of this amount,
$673 million, or 90 percent, of the $750 million in program
contingency reserves associated with the capital costs of
particular bridges relates to the East Span. Although support
costs are not broken out by bridge, based on the fact that
the East Span accounts for 90 percent of bridge specific
contingency amounts and 90 percent of project specific cost
The East Span’s estimated overruns, we believe it is reasonable to attribute 90 percent
cost is $5.9 billion, of the $150 million in contingency related to support costs,
including its share of or $135 million to the East Span. In total, it therefore appears
the program contingency that the East Span costs, including amounts related to the
reserve. program contingency, total about $5.9 billion. Of this amount,
the signature span cost is $2.6 billion, including $455 million
related to the program contingency.
Since 2001, the East Span also has been the source of the
program’s longest schedule delays. As seen in Figure 3, in
August 2004, Caltrans expected the program to be completed
by 2013, four years later than it estimated in 2001. This delay
can be attributed almost entirely to the signature span. Caltrans
postponed the bid opening five times during the advertisement
period, delaying the project by almost one year, and agreed to
give contractors three more years than it originally envisioned
to complete their work. With longer schedules, costs increase
because some level of Caltrans’ support staff must be retained
for the program’s duration. In addition, as schedules lengthen,
inflation lifts costs in general, and there is more risk of
unexpected price increases.

* The timeline for the East Span replacement assumed that Caltrans would accept the sole bid received for the signature span’s

Seismic Retrofit Work Has Proven to Be Difficult to Estimate
According to Caltrans, not only are the toll bridges the largest
and most complicated bridges in the State, but nowhere in
the world have bridges as complex as these been seismically
retrofitted. Furthermore, a consulting firm hired to perform
a cost review of the toll bridge seismic retrofit program
reported that the proposed East Span is sufficiently unique
that traditional estimating metrics for highway construction
do not apply. In addition, the joint venture design firm for the
Richmond-San Rafael Bridge says it is using retrofit strategies
at scales never used before and that circumstances such as
these produce a greater degree of cost uncertainty and limit the
ability to draw from past experiences and to employ traditional
estimating practices.
Recognizing these significant challenges, Caltrans used
numerous outside experts and academic advisers when
estimating project cost. Under Caltrans’ supervision, private
consulting firms prepared the cost estimates for all the toll
bridges, except for the west span of the Bay Bridge, which
Caltrans prepared on its own. Caltrans attributes much of the
difficulty in retrofitting the structures to factors such as variable
soils and foundations, basing retrofits on seismic forces much
2200 California State Auditor Report 2004-140 California State Auditor Report 2004-140 2211
stronger than those the original bridges were designed for,
aging structures, heavy traffic volumes, conflicts with utilities,
and various environmental concerns. Further, several of the
Northern California toll bridges span geologic formations
that place some portions of the respective bridges and their
foundations in locations of rock and other portions in mud.
Also, much of the foundation work is underwater, a condition
that Caltrans has found difficult to estimate accurately. All
these factors have presented Caltrans with a unique and
unprecedented task when estimating project costs.
VARIOUS FACTORS CONTRIBUTED TO THE HIGHER
COST ESTIMATES AND DELAYS
No one factor alone caused the significant rising cost estimates
affecting the seismic retrofitting of selected toll bridges. The
Caltrans’ limited access multiplicity of factors, along with the limited access Caltrans
to the proprietary data has to the proprietary data that supports contractors’ bids,
that supports contractors’ makes it difficult to attribute dollar effects to specific causes.
bids makes it difficult to According to standard provisions in Caltrans’ contracts for the
attribute dollar effects to program, a contractor must submit to Caltrans all documentary
specific causes. information used in preparation of its bid. The documentation
is to be so detailed as to allow for an in-depth analysis of the
contractor’s estimate. However, Caltrans has only 48 hours after
receipt to examine the bid documentation to make sure it is
authentic, legible, and includes the necessary documentation to
support the bid before sealing it and depositing it in an agreed
upon commercial bank for storage. After this point, Caltrans
and the contractor may retrieve and jointly review the bid
documentation in order to assist in the negotiation of price
adjustments and change orders, or to assist in the resolution or
in the settlement of claims or disputes. Nevertheless, according
to contract provisions, Caltrans agrees to safeguard the bid
documentation against disclosure to the fullest extent permitted
by law, as it is acknowledged to constitute trade secrets and is
not deemed a public record.
These limits on access and disclosure of information are an
important reason why Caltrans cannot provide detailed support
for the increased costs it attributed to particular factors in its
communications with the Legislature in August 2004. Caltrans
provided us with its presentation, which included a table of the
factors to which Caltrans attributes the program’s cost increases.
For example, Caltrans cited $200 million in extra costs due to
bonding and insurance market changes, $200 million related
to limits on competition due to construction industry capacity,
2222 California State Auditor Report 2004-140 California State Auditor Report 2004-140 2233
and $525 million related to risks for construction delays. The
chief deputy district director over the toll bridge program said
that the amounts were based on the professional judgment of
program managers and that there was no documentary support
that identified the methodology or calculations attributed to
each factor. According to its director, Caltrans derived these
amounts from construction industry input, Caltrans’ structural
material escalation indices, steel industry publications, ongoing
contractor contacts, and historical toll bridge construction data.
Nevertheless, comparing Caltrans’ two cost estimates, from 2001
Our analysis suggests and 2004, we found that much of the program’s cost increases
that a number of factors, occurred in several areas such as structural steel, contractor
including volatile market overhead, and support costs. Although unable to fully define
conditions and project the underlying causes of these increases, our analysis suggests
delays, led to higher cost that a number of factors, including volatile market conditions
estimates in 2004. and project delays, led to higher estimates. After reviewing these
factors, it appears that at the time Caltrans created the estimates
for AB 1171 in April 2001, it could not have foreseen issues that
explain major increases in cost, with the exception of the lack of
full cost escalation.
As part of its planning and design phases, Caltrans or its
consultants prepared detailed cost estimates reflecting the
materials and services they believed were needed to retrofit
or replace each toll bridge. For two parts of the East Span,
the skyway and the signature span, and for the Richmond-
San Rafael Bridge, we categorized these costs for Caltrans’ two
estimates—one from 2001, when AB 1171 was passed, and
the other from August 2004—and analyzed cost changes to
determine where significant variances occurred. Cost categories
include those for materials, such as structural steel and precast
concrete, as well as intangible costs such as contractor overhead
(including mobilization) and Caltrans’ support costs. Figure 4
on the following page highlights the categories with the most
significant cost increases, showing that five areas—contractor
overhead, structural steel, and contingency reserves for the
East Span’s skyway and signature span; support costs for the
East Span; and the program’s contingency reserves—account for
the bulk of the program’s cost increases.

Giving more detail on increases for each of the cost categories
we reviewed for the skyway, signature span, and Richmond-
San Rafael Bridge projects, Table 4 shows that a few types of
costs account for most of these projects’ cost increases.
Our analysis points to the following market and project
developments that led to higher estimates for these cost categories:
• Higher steel prices.
• Lengthened schedules that increased the need for contractor
overhead and Caltrans support, and further escalated costs.
• Escalation that Caltrans did not apply to the entire life of the
projects at the time of AB 1171.
• Difficulties with underwater work.
• Recognition of significant continuing risk that led to
increased contingency reserves.

Volatile Market Conditions Contributed to Cost Increases
for Materials
Caltrans has experienced large increases in the cost of building
Our analysis suggests materials that can be attributed in part to increases in market
that a number of factors, prices and other less quantifiable factors. The largest materials
including volatile market cost increases are for the more than 60,000 tons of structural
conditions and project steel needed for the signature span’s superstructure, with its
delays, led to higher cost 525-foot steel tower, deck, and suspension cable. Structural steel

to the May 2004 contractor’s bid.
Projects often face fluctuation in material cost estimates up
to the point of locking in contracted amounts. Estimators
account for fluctuations related to general price trends by using
escalation rates in estimates, but escalation rates do not cover
unexpected spikes in market prices. Also, cost increases between
estimates and contract bid amounts can be affected by differing
estimates of the quantity of materials needed to accomplish
particular design objectives, although these do not appear to be
significant in this case.
Caltrans saw a $498 million, or 137 percent, increase in the
cost of structural steel items for the signature span. Part of this
increase is attributable to a significant increase in the price
of structural steel in the first half of 2004. According to an
industry index that Caltrans engineers use to monitor steel price
fluctuations, the industry experienced a 26 percent increase in
structural steel prices in the first half of 2004. We applied this
percentage to the $365 million in structural steel costs estimated
for the signature span under AB 1171 to get a rough idea of its
impact on materials costs. This computation yields $95 million
in extra structural steel costs.
Although steel prices played a part in rising costs, increases in
some bid items are well over what can be explained by a general
increase in steel prices. For example, the signature span calls
for the building of a steel falsework, identified as “temporary
towers” in the bid document, to support deck segments during
bridge construction. The temporary towers are designed to hold
the signature span in place until the permanent tower is built
and the cable suspension for the bridge is in place. Afterward,
the contractor will remove the temporary towers. At the time
of AB 1171, when the bridge design was about 65 percent
complete, Caltrans estimated that this temporary structure
would cost $10 million. The 26 percent increase in structural
steel prices in the first half of 2004 would increase this estimate
2266 California State Auditor Report 2004-140 California State Auditor Report 2004-140 2277
by $2.6 million to $12.6 million. When Caltrans’ consultant

Caltrans received in May 2004, the signature span temporary
towers were estimated at $215 million, far beyond the amount
by which higher steel prices would have increased the cost. Of
the $205 million difference between the bid and the AB 1171
estimate for the tower, only about $2.6 million can be attributed
to the price of steel applied to the initial quantity of steel, as
opposed to the quantity of steel, labor to install the steel, risk,
profit, or other factors.
We asked Caltrans staff to explain this significant increase,
specifically questioning whether a portion could be explained
by a difference between the quantity of steel Caltrans’ estimated
and what the bidder calculated it needed to construct the
temporary towers to support the load of the permanent
structures. The director told us that, given the load requirements
for the temporary towers, the consulting firm Caltrans used
to estimate cost and materials requirements verified that its
quantity estimates are still valid. Thus, the director indicates
that the higher than expected bid amount likely is due to a
number of other factors. For example, the bidder may have
included in that amount the costs for the heavy equipment used
to lift the deck into place, instead of putting those costs in the
line items for erecting the related structural steel items. Also,
the bidder may have incorporated an amount to reflect the risk
related to how long the temporary towers would have to support
the permanent work. Further, the director said the contractor’s
cash flow also might have played a role. Specifically, the bidder
may have moved amounts from another line item into the
temporary tower line, an early payment line item, in order to
receive contract payments earlier than if it had included the
amounts in other biddable items.
When we asked Caltrans for other explanations of cost increases,
the director said he believes the bidding contractor might have
added on a margin to its materials costs to cover other project
costs not identified individually in the project’s bid items. He said
that risks for future significant material escalations, bonding and
insurance costs, as well as the perceived risk of the project, might
have been included in such a margin. Because Caltrans has limited

overall bid amount. extensions to project timelines, which lengthened the period for
which administrative services would be needed, also explain part
of the increase in these costs. Addenda to the proposed contract
for the signature span’s superstructure, made in response to
Caltrans’ meetings with potential bidders, added three years to
the time allowed to complete the East Span project.
Typical of bid documents, the signature span and the skyway
bids included separate lump sum amounts for time-related
overhead and mobilization. Caltrans defines time-related
overhead as the daily cost for the contractor’s field and home
office managerial and administrative staff as it relates to the
number of days needed to complete a contract. The field office
cost also includes rent, utilities, maintenance, security, supplies,
and equipment expenses of the project field office. After a
contract is signed, time-related overhead costs may increase or
decrease as changes extend or reduce the contract completion
date. Contract change orders allow added payment for project
delays. Additionally, Caltrans defines mobilization as the cost of
moving laborers, tools, construction equipment, construction
materials, and incidentals to the project site; establishing offices,
buildings, and other facilities necessary for work on the project;
and all other costs that must be incurred before beginning work
on various contract items on the project site.
The contractors’ bids for time-related overhead items for the
skyway and the signature span of the East Span were much
higher than Caltrans anticipated. For the skyway bid these costs
were $208 million, or 235 percent higher, and for the signature
span the costs were $243 million, or 501 percent higher, than
Caltrans’ AB 1171 estimates. The director indicates that Caltrans
normally calculates overhead costs as a percentage of capital
costs. Further, he indicates that at the time of AB 1171, Caltrans’
standard rate for estimating time-related overhead was 5 percent,
but it applied a rate of 10 percent to East Span projects because
2288 California State Auditor Report 2004-140 California State Auditor Report 2004-140 2299
of the greater risk of the projects. However, rates for time-
related overhead for the two projects in the August 2004
estimates, which reflect actual contractor bids for the project,
are much higher—20 percent for the skyway and 15 percent
for the signature span. Since 2001, the director indicates
that Caltrans capped this bid item at a rate of 15 percent.
However, he says Caltrans believes that market conditions after
September 11, 2001, have led to higher insurance and bonding
costs, and greater scrutiny of risk on large projects, which has
contributed to higher time-related overhead bid amounts.
In addition, schedule delays and contract extensions increased
time-related overhead. Caltrans pushed out the construction

time-related overhead given to construct the signature span’s superstructure. During

20 percent, respectively, time allowed for project completion, increasing the contract
of capital costs. length to well over six years. These changes indicate that the
signature span‘s superstructure was more complicated than
Caltrans originally envisioned and so could be expected to use
considerably more administrative resources. Considering that
the addenda doubled the length of time for construction, a
large increase in time-related overhead could be expected. For
example, once construction was under way on the skyway,
delays added 202 days to the time to complete the project as
of November 2004, and contract change orders related to the
delays added $25 million to time-related overhead.
Additionally, mobilization was a major factor in increased
overhead costs for the signature span. Although the
mobilization bid for the skyway project came in about as
Caltrans expected under AB 1171, it was significantly higher
than expected for the signature span. The mobilization amount
for the skyway increased $30.8 million from AB 1171 to
Caltrans’ August 2004 report, an increase that was similar to
that for the overall skyway contract. Mobilization represented
about 10 percent of skyway capital costs, which is what Caltrans
had contemplated. However, the August 2004 signature span
estimates include $233 million for mobilization, or nearly
15 percent of overall capital costs, an increase of $187 million
2288 California State Auditor Report 2004-140 California State Auditor Report 2004-140 2299
over Caltrans’ AB 1171 estimate. The East Span project manager
attributed the higher mobilization costs for the signature span
to the fact that Caltrans increased contractual mobilization
payments to relieve cash flow constraints on contractors and
to mitigate the cost of financing; she believed both actions
should have resulted in a reduced bid, not an increased one.
Additionally, she states that the overall increase in capital costs
would translate to a higher mobilization bid due to the payment
structure under the contract provisions.
Increases in Estimates for Caltrans’ Support Costs
Contributed Significantly to Overall Program Costs
Support costs for Caltrans’ administration of the program
increased significantly between the Caltrans’ AB 1171 and
Caltrans’ support costs, August 2004 estimates, accounting for $556 million, or
including staff salaries, 20 percent, of the overall cost increases before program
consultant fees, and other contingencies. Support costs include such expenses as
operating costs, account staff salaries, consultant fees, and other operating costs of
for $556 million, or administering the construction activities involved in retrofitting
20 percent, of the overall the toll bridges. The increased support costs in Caltrans’
cost increases before August 2004 estimate reflect the dramatic rise in the program’s
program contingencies. capital costs, a key variable in Caltrans’ method for estimating
its support costs, and time delays. Estimated capital costs
increased by 58 percent between April 2001 and August 2004,
while estimated support costs have grown slightly more, by
70 percent, over the same time period.
The program’s significant timeline delays and extensions also
offer an explanation for why support costs, similar to contractor
overhead costs, would be expected to increase. The support
costs estimated under AB 1171 in 2001 extended through
2007; however, the August 2004 estimate accounts for support
costs through 2012. Caltrans will have to retain consultants
and staff to support construction during the added five years
of the program. Maintaining this workforce can be expensive.
For example, Caltrans’ expenditures for support costs averaged
about $8 million per month for the 12-month period ending in
October 2003. Using this same monthly rate over the five-year
difference between the AB 1171 and August 2004 calculations
could account for roughly $480 million of the $556 million
increase in the program’s support costs.

Caltrans Underestimated Price Escalation
For large construction projects that extend over a period of time,
estimates need to build in escalation rates for inflation over a
Caltrans applied an project’s life. Caltrans incorporated an annual escalation rate
escalation rate to its of 5 percent into its AB 1171 cost estimates for components of
AB 1171 estimates up to the East Span, but only to the time when it expected to receive
the time that it expected contractor bids. Although cost estimating can never be an exact
to receive contract science, Caltrans knew that the bids it received would reflect
bids, but not for the that costs for materials and services used for its projects would
construction phase. continue to rise through the construction phase; therefore,
one would expect its estimates to include a consideration of
escalation through the construction phase. To reflect inflation
that would occur during construction, Caltrans should have
extended its escalation calculations to cover the expected time
to complete these components. For example, AB 1171 estimates
prepared in 2001 included $90 million in escalation costs for the
signature span through November 2002, when Caltrans expected
this structure would take four years to construct. During this
period, prices would continue to rise, resulting in extra costs
that contractors would be expected to build into their bids. One
way to estimate the effect of inflation through the construction
period is to escalate total costs through the midpoint of this
phase. This gives a rough approximation, avoiding estimation
of each year’s remaining contract balance. Using this method
to escalate the signature span’s total capital costs through the
mid-point of the expected four-year construction period and
using Caltrans’ 5 percent escalation rate, we calculate that the
AB 1171 cost estimates for the signature span may have been
approximately $70 million higher. For the skyway, escalating
costs through the mid-point of the expected construction period
would have yielded an AB 1171 estimate that may have been
approximately $69 million higher than Caltrans’ figure.
Similarly, extending the program four years would have had
a large impact on capital costs above that which is calculated
in the prior paragraph. Further inflating capital cost estimates
under AB 1171 for this extension, we estimate that it could
account for up to $110 million of the signature span cost
increase. These potential costs that contractors can be expected
to add to their bid costs help explain some of the otherwise
indeterminable cost increases related to structural steel,
overhead, and other costs.

Underwater Work Increased Costs for the
Richmond-San Rafael Bridge
The retrofit of the Richmond-San Rafael Bridge has faced
many obstacles related to underwater work. Underwater debris
discovered after construction began, deeper than expected
bedrock at several locations, and lack of clearance for driving
micropiles have challenged the contractor working on the
project. Change orders reflecting these difficulties of underwater
work have added $47.6 million to the project’s costs.
According to the retrofit project manager for the Richmond-San
Rafael Bridge, Caltrans hired a consulting firm during the project’s
design phase to conduct geotechnical test borings, mostly to
determine the depth and thickness of the bedrock base. However,
Caltrans accumulated the extent to which this base varied was not discovered until
$47.6 million in work began. Also, the test borings were not designed to detect
additional costs related buried debris left over from the original bridge. Further, he

underwater debris. had accumulated about $22 million in approved or pending
contract change orders related to the removal of underwater
debris, most of it, according to the retrofit project manager, left
behind when the bridge originally was constructed. This debris
was not on the as-built plans for the bridge and was located
primarily below the mud line over the length of the project. The
engineers on the current retrofit project did not become aware
of the problem or its extent until Caltrans conducted a detailed
diving inspection of the piers after construction began. The
retrofit project manager told us that Caltrans did not expend
the resources to conduct a diving inspection as part of the
design phase because it did not anticipate the types of problems
discussed here and because the debris was not shown on the as-
built plans.
Also, conditions related to the piling work on the Richmond-
San Rafael Bridge have resulted in a number of project change
orders, totaling roughly $11.6 million. According to the retrofit
project manager, the contractor has had difficulty with some of
the piling work because they discovered that soil conditions and
bedrock depth varied considerably over short distances, creating
the need to shorten or lengthen piles. To minimize delays that
could prolong the job, Caltrans has agreed to pay for much of
the added costs, including additional labor shifts, needed to
3322 California State Auditor Report 2004-140 California State Auditor Report 2004-140 3333
complete the work. Caltrans had conducted geotechnical work
in the design phase, which included 20 test borings, but these
efforts did not uncover the extent of the ground variance.
Finally, the installation of underwater micropiles has continued
to cost more than anticipated. According to the retrofit project
manager, Caltrans knew that if the original bridge piles were
driven according to plan, the contractor would have only
four inches of clearance for driving the micropiles. However, the
contractor found that some of the original bridge piles had not
been driven straight into the bedrock, but were sitting at odd
angles, which eliminated the small amount of clearance needed
to drive the new micropiles. Consequently, Caltrans sometimes
had to pay the contractor for redesigning and redriving the
micropiles, a significant amount of extra work for the contractor.
Change orders related to micropile work have cost Caltrans
more than $14 million over contracted amounts.
The Program’s Contingency Reserves for
Potential Cost Increases Remain High
Part of the anticipated $3.2 billion increase in the August 2004
estimates include contingency reserves to cover potential costs
related to the program’s unique estimating challenges. Caltrans
looks to its contingency reserves to cover unforeseen costs
and potential claims related to identified problems, generally
establishing a contingency reserve for each project and sometimes
In August 2004, a program-wide contingency reserve. In its August 2004 cost
estimated contingency estimates, Caltrans established contingency reserve amounts for
reserves for the skyway, the skyway, signature span, and the Richmond-San Rafael Bridge
signature span, and that are significantly higher than contingency reserve levels of
Richmond-San Rafael more typical projects, reflecting the greater amount of risk these
Bridge were significantly projects have for schedule delays and cost overruns.
higher than for more
typical projects. Compensating for the limited information available during the
planning phase of a project, allocations for contingency reserves
start high, and then generally decrease as funding is transferred
from them to identifiable cost categories. At project completion,
amounts remaining in the reserve represent the extent to which
a project has been completed for less than the budget or cost
estimate. Following this logic, Caltrans’ policy dictates that
reserves should range from 30 percent to 50 percent of project
costs in the conceptual stages of a project. Once a project is
approved and progresses into its planning and design phases,
the contingency reserve percentage is reduced. By the time a
project is advertised for bid, contingency reserve levels normally
3322 California State Auditor Report 2004-140 California State Auditor Report 2004-140 3333
are reduced to about 5 percent of the project’s cost. Caltrans’
policy states that any percentage higher than this must be
justified based on the atypical nature of the project.
As shown in Table 5, the contingency reserve amounts that
Caltrans built into its August 2004 cost estimates for the skyway,
signature span, and the Richmond-San Rafael Bridge remain
substantial, sometimes even above AB 1171 cost estimates in
terms of the percentage of capital costs they represent. The
project contingency reserves are also significantly higher than
contingency reserve levels of more typical projects under
normal Caltrans guidelines. In August 2004, the skyway and
the Richmond-San Rafael Bridge were under construction
and Caltrans had received a bid for the signature span’s
superstructure. As discussed earlier, normal policy indicates
reserves of 5 percent or less in these circumstances. According
to its director, Caltrans estimated additional contingency
reserve amounts for the projects not yet completed based
on data derived from contracts currently in or not yet under
construction, as well as historical information from completed
toll bridge construction contracts.
Further, in August 2004, Caltrans estimated that it needed a

that came out of this process represents the reserve level Bechtel
concluded was required to provide an 80 percent likelihood the
program cost estimate will not be exceeded. In addition, Bechtel
performed a schedule risk analysis for construction and applied a
program contingency to support costs.
For the risk analysis model, Bechtel drew not only on Caltrans’
experience with the toll bridge seismic retrofit program, but
also from its own role in monitoring and reporting bridge and
highway improvement projects funded under the Bay Area Toll
Authority’s (BATA) Regional Measure 1 (measure 1) program. In
its role on the measure 1 program, providing project monitoring
services, Bechtel has become familiar with Caltrans’ difficulties

with other toll bridge construction in the Bay Area, including
significant cost and schedule impacts associated with foundation
work in water. For example, the new Benicia-Martinez Bridge,
currently under construction, has experienced cost overruns
of nearly 81 percent over its June 2000 budget, rising from
$586 million to nearly $1.1 billion as of September 2004.
Similar to the Richmond-San Rafael Bridge, the Benicia-Martinez
Bridge has had many difficulties with underwater construction
work, which account for most of this cost increase, according
to Bechtel’s project monitoring reports to BATA. For example,
Bechtel’s May 2004 report notes that the project experienced
problems such as installing foundation rock sockets, mitigating
the effects of pile driving on fish, and driving piles to the
required elevation. Caltrans experienced smaller cost increases
on the west span replacement for the Carquinez Bridge, another

measure 1 project, which saw an increase of 18 percent above its
June 2000 budget, increasing from $433 million to $512 million
as of September 2004.
With Continuing Uncertainties, the Program’s Costs May
Rise Further
Despite the significant increase in the program’s estimates,
costs could go even higher, according to August 2004 reports by
Caltrans and by Bechtel. The August 2004 estimates assumed
that Caltrans would accept the bid for the signature span’s
superstructure and thus keep the program on schedule. In its
report, Caltrans stated that if the bid expired, it would have to
readvertise and rebid the superstructure, possibly resulting in a
one-year schedule delay and a significant escalation of costs. As

East Span. if the superstructure was readvertised and rebid, or redesigned.
Specifically, Bechtel concurred with Caltrans that rebidding the
superstructure using the same design could increase project costs
in a range from nothing to as much as $200 million. Similarly,
Bechtel agreed with Caltrans’ analysis that redesigning this
component of the East Span as a typical cable-stayed bridge could
save the program $85 million but also might increase program
costs by $310 million, depending on time delays that Caltrans
estimated could range from two-and-a-half to four years.
Bechtel was careful to say that its review was not a detailed
estimate of program costs and that it did not perform a value
engineering analysis. Further, Bechtel stated that Caltrans and
BATA provided the information used in its evaluation, but that it
did not independently verify that information. Rather, Bechtel’s
cost review was a trend analysis of the current Caltrans’ forecasted
cost for the program based on individual project contracts.
Bechtel also performed a pricing validation on the East Span
contracts not yet awarded, completed cost risk and schedule risk
analyses, and evaluated the program’s contingency reserve.
According to the commission, in September 2004, Caltrans,
with a preliminary review by Bechtel, developed a cost estimate
for rebidding a skyway design to replace the signature span.
Before considering other factors such as schedule delays and
3366 California State Auditor Report 2004-140 California State Auditor Report 2004-140 3377
the cancellation and modification of existing contracts, this
estimate indicates that a skyway design would cost $665 million
less than the signature span. According to the commission,
Caltrans estimated that costs associated with the other factors
would, however, largely off set this gain, yielding either savings
of $255 million or additional costs of $140 million. The cost
that Caltrans may have incurred to build a skyway over the
span that is now the skyway plus the signature span cannot be
known with certainty. Even if Caltrans had requested bids for
the skyway that it initially recommended, the amount of change
orders to the contract would not be known. However, Caltrans’
September 2004 estimate of the capital cost for building an
additional section of skyway instead of the signature span
indicates this section of skyway would cost $935 million, which
is $665 million less than Caltrans’ current estimated capital cost
for the signature span, without project contingency reserves.
This portion of the skyway would thus cost about $1.51 million
per meter versus a cost of $523,000 per meter for the current
skyway. According to the commission, Caltrans’ higher cost
estimate accounts for a number of factors, such as deeper
marine foundations, rock interface for foundations, longer
spans and taller pier columns, that would make the unit cost of
building this particular section of the skyway more expensive
than the unit cost of the skyway project that is currently under
construction. The $665 million savings may, however, be lower
than the savings that an earlier decision to choose the skyway
design would have generated. Caltrans’ estimate reflects today’s
prices, which are higher than those that would have applied in
earlier periods. In addition, Caltrans’ estimate does not include
savings for project and program contingency reserves or support
costs even though the skyway structure is less complex than the
signature span.
On December 10, 2004, Caltrans published a study that
recommended either completing the signature span as originally
designed or extending the skyway across the East Span. Caltrans’
study included a range of total costs for each option. We
requested the schedules supporting Caltrans’ cost figures, as well
as its reconciliation of the cost figures to its August 2004 report
to the Legislature. However, because we had already sent a draft
report to Caltrans for its review and comment, and because we
did not receive the schedules from Caltrans with sufficient time
to review them prior to publishing this report, we were unable
to analyze the cost figures in this study. n

CHAPTER 2
Caltrans’ Project Management
Practices Need Improvement
CHAPTER SUMMARY
The Department of Transportation (Caltrans) has
neglected several important aspects of project
management that could have helped it maintain
realistic and up-to-date estimates of program costs and risks,
and communicate those estimates in a timely manner. As
shown in the last chapter, Caltrans Toll Bridge Seismic Retrofit
Program (program) has been threatened by sharp increases
in cost estimates and major schedule delays. Although the full
extent of the program’s financial crisis became apparent only in
August 2004, when Caltrans presented its new cost estimate to the
Legislature, Caltrans had numerous earlier indications that the
program would exceed the Assembly Bill 1171 (AB 1171) budget.
Although it hired consultants to analyze project risks and
acted to mitigate some risks associated with the unprecedented
San Francisco-Oakland Bay Bridge east span (East Span) project,
Caltrans did not develop a comprehensive risk management
plan for this project. Our review of project risk management
focuses on the East Span because this unique project accounts
for $2.5 billion of the $3.2 billion cost overrun and four-year
schedule delay, discussed in Chapter 1. Although Caltrans
identified certain risks through various analyses, it has not
performed some of the major processes—planning, tracking, and
quantifying—necessary to maximize the chances of positive
rather than adverse events in the East Span project. Also,
Caltrans did not quantify the potential dollar costs to the project
of various risks until August 2004, when it reported soaring cost
estimates to the Legislature. Although the East Span project
began in 1998, Caltrans states that it now intends to enhance its
risk management process and create a risk management plan for
the project.
Caltrans also has not followed generally accepted cost
management practices to help ensure that the project could
be completed within its 2001 budget in AB 1171. Caltrans
did not regularly update its cost estimates for the East Span
project or the entire program, including updating estimates for
3388 California State Auditor Report 2004-140 California State Auditor Report 2004-140 3399
capital costs, support costs, and contingency reserves, which
should cover the cost of known potential risks and unknown
risks. Without updated cost estimates, Caltrans cannot give
program managers a detailed overview of the program’s capital
and support costs for all the bridges. Because Caltrans did not
regularly update the projected costs for the program, it could
not assess whether it was staying within budget. Had it been
monitoring the program’s costs regularly, Caltrans would have
realized much earlier that the program was exceeding its budget
under AB 1171.
Caltrans issues contract change orders for various reasons, such
as adjusting contract plans or having a contractor do extra work.
We reviewed a sample of 20 large change orders and found that
Caltrans complied with its internal policies and procedures.
Finally, Caltrans has not paid enough attention to
communications management, failing to inform its major
stakeholders such as the Legislature and the Metropolitan
Transportation Commission (commission) of potential cost
overruns. Although state law requires periodic status reports to
the Legislature, Caltrans provided no reports for time periods
after 2002 until August 2004. Caltrans had strong indications
that the program’s costs would exceed the AB 1171 budget
as early as November 2003, when it provided an annual
financial plan update (financial plan) to the Federal Highway
Administration (FHWA). However, this financial plan did not
reflect Caltrans’ internal cost estimates, so it understated the
extent of the program’s financial risks. By failing to disclose cost
overruns until long after it became aware that the program likely
would exceed its budget, Caltrans placed the Legislature in the
awkward position of having to try to devise a funding solution
six weeks before the bid on the most expensive component of
the East Span project, the signature span’s superstructure, was
set to expire. Also, by not providing timely information to the
commission or the Bay Area Toll Authority (BATA), Caltrans
ignored critical stakeholders who represent the San Francisco
Bay Area (Bay Area) on transportation planning issues.
THE PROJECT MANAGEMENT BODY OF KNOWLEDGE
DESCRIBES IMPORTANT MANAGEMENT PRACTICES
The Project Management Institute, recognized for its
development of standards for the practice of project
management, publishes the highly regarded A Guide to the
4400 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4411
Project Management Body of Knowledge (PMBOK Guide), which
identifies and describes generally accepted project management
practices. The PMBOK Guide defines nine knowledge areas that
organizations must manage in every project to ensure successful
completion: integration, scope, time, cost, quality, human
resource, communications, risk, and procurement. We focused
our review on three areas of project management: project risk,
cost, and communications management.
Caltrans recognizes the importance of the PMBOK Guide: its
project management handbook emphasizes the nine knowledge
areas and often cites the PMBOK Guide. Caltrans’ departmental
project management policies have incorporated all the knowledge
areas since before the inception of the program, with its 1997
handbook acknowledging that understanding and applying those
areas to a project is crucial to delivering a successful project. In
2003, Caltrans further emphasized the importance of applying
the PMBOK Guide’s project risk management guidelines and
its project communication management guidelines when it
published separate handbooks for its project managers on each
knowledge area.

information sessions with potential suppliers, steel fabricators,
and contractors, Caltrans has not performed some of the major
processes—planning, tracking, and quantifying—necessary to
maximize the chances of positive rather than adverse events in
the East Span project.
Although successfully working to mitigate some of these
risks and achieve project objectives, Caltrans also identified
numerous, significant risks to the project that it did not quantify
in terms of potential added costs. Further, Caltrans did not
estimate the potential costs associated with project risks and

then suffi ciently update estimates of reserves it needed on the
East Span project based on an analysis of its experience with
other Bay Area bridge projects.
The PMBOK Guide observes that risk management processes
must be commensurate with the project’s risk and importance to
an organization. With its unique and unprecedented design and
high cost, the East Span has extraordinary strategic, technical,
and fi nancial risks. Also, the success or failure of the East Span
signifi cantly affects Caltrans’ reputation as well as its ability to
complete an essential public safety program. Caltrans’ project
risk management handbook (risk management handbook),
published in June 2003, cites that project risk management is
most effective when fi rst performed early in the life of the project
and is a continuing responsibility throughout the project.

lacked the solid risk management foundation
that a documented and working plan could
provide. According to its director, Caltrans is
completing documentation for a comprehensive
4422 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4433
risk management plan for the East Span project. Further, the
director indicates that elements of this plan will include risk
identification, mitigation strategy, history of risk management,
a schedule of regular risk analysis on the contracts, and
identification of the group responsible for implementation of
this plan.
For our benefit, in October 2004 Caltrans put together a
summary that is supposed to be the risk management plan
for the East Span project. This summary includes primarily a
historical description of methods Caltrans used to identify risks,
and names of individuals who are a part of its Project Quality/
Risk Assessment/Oversight Group (risk assessment group).
However, the summary omits how Caltrans will perform key
risk management processes the PMBOK Guide deems critical to
successful risk management and that Caltrans’ own handbook
prescribes. For example, the summary does not define how
Caltrans will identify and quantify risks throughout the life
of the project and how risk activities will be documented and
tracked. Moreover, Caltrans created this summary especially
for us, so it was not actually used as the plan to manage the
East Span project’s risk.
In a February 2003 report, a consulting firm Caltrans hired to
perform a quality assurance check and risk assessment of the
estimated construction schedule for the East Span, warned that
the East Span project’s complexity and uniqueness warranted
an increased risk management effort. The consultant concluded
that Caltrans and the commission should have a workable risk
management system in place and continually monitor the
risk profile. Further, the consultant stressed that an essential
part of risk mitigation for the project would be to form a

quality assurance procedures to mitigate this risk and that
4422 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4433
Caltrans assign oversight authority for this and other procedural
matters to the risk management team. Another risk cited by the
consultant related to Caltrans using multiple contracts for the
East Span project. Caltrans did this to improve competition and
potentially increase the number of bidders, but the consultant
pointed out that the use of multiple contracts introduced risks
for delays and that additional coordination and communication
procedures to mitigate these risks should be overseen by the risk
management team.
In response to the consultant’s recommendation to create a
dedicated risk management team for the East Span project, the
East Span project manager indicates that the risk assessment
group is responsible for risk management for the project and
that a group of managers, called the “level 4 group,” meets
quarterly to identify and discuss mitigation strategies for
construction risks related to the East Span. The members of the
risk assessment group are important stakeholders—individuals
who are actively involved in, exert influence over, or are
affected by the project—who should be consulted regarding
identifying risks and project risk status. Caltrans indicates the
risk assessment group provides the following areas of expertise:
improving contract administration practices; enhancing policies,
procedures, and products; encouraging streamlined resolution
of issues; and assessing and implementing project direction and
changes. Further, the East Span project manager states that the
risk assessment group and Caltrans’ executives have an ongoing
active role in the project.
Having these groups is a good first step in addressing risk
management issues for the project; however, neither group

stated the risk assessment group has biweekly videoconferences
as part of a larger group that includes Caltrans’ chief engineer,
executives, and project team members. She indicates that the
purpose of the videoconferences is to evaluate and resolve
identified schedule and cost risks. However, agendas for these
videoconferences indicate that, although risks are discussed as
part of the meetings, Caltrans did not develop the systematic
methods of risk planning, identification, prioritization,
quantification, and tracking to ensure that its risk management
activities are effective. The group discusses individual risks, but
4444 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4455
there is no system in place to track these risk discussions. In fact,
of the 29 videoconferences Caltrans held from January 2003
through September 2004, only four times in early 2003 did
Caltrans distribute meeting minutes to attendees that reflected
agreed upon tasks and decisions made. Up to January 2003,
the East Span project manager indicates that Caltrans used a
status report to record action items from these discussions;
beginning in January 2003, she provided us agendas with her
handwritten notes as the record of action items. However, the
East Span project manager’s handwritten notes are not organized
in any fashion to show the importance of issues or how
Caltrans tracked them. Of the eight meetings that the East Span
project manager indicates the “level 4 group” held between
December 2002 and September 2004, she provided minutes
to four of those meetings and the agenda to another meeting.
Although these meetings show that the group discussed various
construction issues related to the East Span, the issues were not
considered in terms of risk to the project nor were there any
discussions related to quantifying risks. Further, none of the
minutes give any indication that the group considered the effects
of these risks on the program’s budget. Also, similar to the risk
assessment group, the minutes and agenda do not track the status
of risks, but rather are a historical record of the events that were
discussed or to be discussed.
Further, best practices say that organizations should track
Caltrans used a status identified risks to ensure that they are mitigated. The East Span
report to track risk project manager indicates that Caltrans used a status report

program-wide status identified in the September 2002 status report was to develop
report to update issues and maintain this program-wide status report to update issues,
and action items. status, action items, responsible persons, and due dates. Since
then, the East Span project manager stated that the agenda and
minutes of the biweekly videoconferences attended by Caltrans
executives and the risk assessment group replaced this status
report. However, as noted previously, the discussions of risks
and action to mitigate them resulting from these meetings
are not tracked, as Caltrans kept minutes for only four of the
29 videoconferences. Moreover, the agendas are merely a
4444 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4455
historical record of the issues to be discussed and are not a tool
that systematically tracks the status, response, and resolution to
identified risks.
Finally, one of the nine members of the risk assessment group
that Caltrans identified, the FHWA Bay Bridge project oversight
manager, said she had never been invited to attend a biweekly
meeting and was not aware of being listed as a member. She
indicated that she attends meetings on a variety of topics to keep
up with project status and noted that issues related to evaluating
and resolving schedule and cost risks are certainly part of any
discussion. However, she said that Caltrans never specifically
asked her to assess risks for the East Span project. Rather, her role
on the project primarily relates to oversight, as opposed to risk
management. She indicates she also participates in the project
analyses because FHWA approval is required on designs and
changes to project designs, and contract change orders.
Caltrans Took Steps to Identify, Prioritize, and Mitigate
Project Risks
Despite Caltrans’ lack of comprehensive risk management plan,
it took several steps to systematically identify, rank, and respond
to the East Span project’s risks. It initiated five project analyses
that discussed project risks and recommended mitigation
steps during 2002 and 2003, as noted on the timeline in the
Appendix. Also, it followed many of these recommendations
on reducing the project’s risks. For example, it acted to reduce
the risk from steel price increases, mismatched steel parts, and
federal regulations requiring the use of domestic suppliers. These
analyses represent proactive steps that Caltrans took to identify,
prioritize, and mitigate risks.
In March 2002, a Caltrans consultant performed a constructibility

review study detailed develop ways to improve contractors’ ability to construct the

and specifications. capacities, and construction market conditions. The study
contained detailed recommendations on 12 major issues affecting
the East Span, as well as 103 recommendations addressing specific
issues with the construction plans and specifications. For each of
the 103 recommendations, the consultant provided an assessment
of the potential cost to the project.
4466 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4477
Following these recommendations, Caltrans began addressing
risks identified in the March 2002 analysis. For example, the
consultant recommended that Caltrans develop a flexible
bidding process because of construction market conditions
and to attract competitive bids for the signature span. Caltrans
followed the consultant’s recommendation by breaking the
signature span into three smaller contracts, thus opening up
the project to a greater number of contractors to maximize the
number of bids received. At this time, Caltrans took steps to
mitigate the risks regarding the price and quantity of structural
steel needed for the signature span. In March 2002, it conducted
an information session to get feedback from suppliers, potential
contractors, and fabricators and to help them better understand
the project. Then, in August 2002, a Caltrans consultant issued
a mock bid report, which evaluated alternatives to an all-
steel structure for the signature span as well as conducted a
comparison of domestic and foreign steel prices.
Caltrans also initiated a quality assurance review by the Caltrans
Central Region (Central Region), issued in December 2002,

cost were the contractor’s financing of the project, fabrication
of steel, profitability of the contractor, and project risk. To
address these concerns, the Central Region submitted 11 specific
recommendations and an overall recommendation to increase
the project cost estimate to $800 million, to better reflect
unknowns in the construction and steel fabrication industries.
The Central Region also recommended that Caltrans pursue a
waiver of the federal regulations requiring use of domestic steel,
which it claimed would have a substantial effect on costs for the
steel tower and other components.
As discussed previously, Caltrans engaged a consultant in
February 2003 to provide a quality assurance check and risk
assessment of the estimated East Span construction schedule.
This review was intended to help Caltrans and state officials
make critical construction and management decisions
necessary to advertise and award the signature span contract.
The assessment identified and ranked risks that could affect
the signature span’s timely completion. The most significant
4466 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4477
schedule risk the report identified was that parts might not fit
together properly because bidders likely would need to rely on
several steel producers and fabricators if the project used steel
only from domestic producers. Caltrans addressed this concern
and the concern identified by the Central Region by adding
provisions to the request for proposal allowing contractors to
provide two cost estimates for signature span bids—one price
using domestic steel and one using foreign steel. When federal
funding is involved, federal regulations require that projects buy
steel from domestic sources, unless the cost of domestic steel is
more than 25 percent higher than the cost of foreign steel.
In the single bid Caltrans received for the signature span in
May 2004, the contractor’s two prices were sufficiently different
to show that federal regulations requiring domestic steel could

require the use of
domestic steel. The February 2003 risk assessment also identified structural risk
issues for the signature span’s components: the foundations,
piers, tower, bridge deck, and cable system. For example,
the consultant believed that the main cable specified for the
signature span could be produced only by a foreign company
unlikely to sell its competitors the unique casting mold for
making the wire. To address this issue, Caltrans obtained
exemption to the federal regulation requiring domestic suppliers
for the signature span’s main cable.
Moreover, in October 2003, Caltrans formed an independent
review committee of consultants, chaired by the former
executive director of the Utah Department of Transportation,
to review the contract requirements for two major East Span
contracts—the signature span and its foundations—before
advertisement. Among other tasks, the committee reviewed
bidder inquiries for the contract, interviewed selected prospective
contractors and fabricators, and assessed a variety of current
and future market conditions. Of the 21 recommendations the
committee issued in its November 2003 report, it believed five
could have a major impact on the actual bid prices. Once again,
the waiver of federal regulations requiring the use of domestic
steel for the signature span was cited as a mitigation step that
could save $50 million to $100 million.
4488 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4499
Each of the five major analyses that Caltrans initiated were
appropriate actions to identify risks. Further, the analyses
recommended steps Caltrans could take to mitigate these
risks. However, as the next section indicates, Caltrans did not
adequately quantify risks related to the East Span.
Caltrans Did Not Adequately Quantify Risks Associated With
the Project
Although Caltrans acted to identify, qualitatively analyze,
and mitigate risks that could affect the East Span, it did not
have a coordinated risk management plan in place to ensure
that it quantified risks in terms of increased costs to the
project. The PMBOK Guide states that organizations should
perform quantitative risk analysis to estimate potential costs
associated with project risks. Further, Caltrans’ risk management
handbook strongly recommends that project managers perform
quantitative risk analysis on projects with extremely high risk
to estimate the probability of meeting project cost and time
objectives. The five analyses discussed in the previous section
identified significant risks that could affect the cost and schedule
of the East Span. By quantifying the potential cost effect on
the East Span’s budget, Caltrans could have better gauged the
likelihood of staying within the AB 1171 budget.
Three of the five analyses quantified risk in terms of potential
Three of the five analyses cost that Caltrans could have used to update its estimates.
Caltrans initiated However, Caltrans did not use these quantified risks to update
quantified risk in terms of its cost estimates. For the other analyses, Caltrans did not ask
potential cost; however, for a determination of the potential cost related to identified
Caltrans did not use these risks. According to the director, the cost update for Caltrans’
quantified risks to update August 2004 report included its first program-wide cost update
its cost estimates. since Caltrans prepared the cost estimates for AB 1171 in
April 2001. After AB 1171 became law, the director said that
Caltrans managed to the budget as set forth in the bill by
mitigating potential risks. Further, according to the summary of
risk actions Caltrans prepared for us, the Bechtel Infrastructure
Corporation (Bechtel) August 2004 cost review was the only
program-wide quantitative risk analysis performed for the
program since AB 1171 was passed. However, Caltrans could
have attempted to estimate potential cost increases as at least
some of the risks were likely to continue to threaten the project
despite efforts to mitigate them.
4488 California State Auditor Report 2004-140 California State Auditor Report 2004-140 4499
Moreover, Caltrans’ consultant evaluated risks for the
February 2003 risk assessment in terms of possible delays to
the schedule, and Caltrans did not attempt to estimate costs
associated with such delays. As indicated in the summary
created especially for us of Caltrans’ risk management activities,
Caltrans did not attempt to estimate increased costs these risks
may pose to the project until the commission hired Bechtel
to produce a cost review report released in August 2004. At
this time, Caltrans was able to estimate that a one-and-a-half
year delay to the project would increase costs by as much as
$320 million, including $120 million in support costs and
$200 million in additional contractor costs. This indicates that
Caltrans had the ability to analyze other areas of the program
and calculate potential cost increases. With its engineering
expertise or with the assistance of a contractor, Caltrans could
have attempted to quantify the additional costs associated with
schedule delays before August 2004.
Also, Caltrans did not adequately address the possibility that
risks it could not identify through its risk management efforts
would affect the ultimate cost of the project. Although such
unknown risks cannot be managed, project managers may
address them by creating a contingency reserve based on past
A December 2002 experience with similar projects. According to the PMBOK Guide,
quality assurance quantitative risk analysis includes using historical information,
review recommended expert judgment, and other sources of information, and
contingency reserves assessing the probability of achieving project cost and time
of at least 20 percent; objectives, to calculate a contingency reserve amount needed for
however, Caltrans’ the project. For example, the December 2002 quality assurance
internal estimates for the review that the Central Region performed found that, based
signature span contracts on its analysis of eight Bay Area seismic retrofit bridge projects,
included only a 5 percent costs had increased by an average of 20 percent over estimates.
project contingency As such, the Central Region recommended including contingency
reserve. reserves of at least 20 percent for unknown risks and for unforeseen
disputes or additional costs to close down the signature span
project. However, from December 2002 through May 2004 Caltrans’
internal estimates for the signature span contracts included only a
5 percent project contingency reserve.
Additionally, the February 2003 risk assessment indicated that
Caltrans should consider applying a statistical risk simulation
to the project. Caltrans did not attempt to do so. The Bechtel
cost review released by the commission in August 2004
included a quantitative assessment of risks to individual project
budgets and for the program. This review included a statistical
simulation to quantify risks in terms of cost. This statistical
5500 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5511
analysis indicated that a $900 million contingency would
provide 80 percent assurance that Caltrans would stay within its
revised budget: $660 million of the program contingency related
to cost risks and $240 million to schedule risks.
The program’s high cost and inherent risks demanded that
Caltrans perform such an analysis on a regular basis, not just
when it was obvious that it would greatly exceed its AB 1171
budget. Bechtel had performed a similar analysis of the program
in 2001. Had Caltrans performed these types of quantitative risk
analyses on an ongoing basis, it may have been able to determine
earlier that it would not stay within the AB 1171 budget.
CALTRANS DOES NOT REGULARLY UPDATE PROGRAM
COST ESTIMATES TO MONITOR THE PROGRAM’S
BUDGET APPROPRIATELY
We reviewed Caltrans’ performance on two key
elements of project cost management—cost
estimating and cost control (see textbox). Cost

project budget. Further, under FHWA major project program cost
estimating guidance, estimates are central for
establishing the basis for key project decisions,
measuring project success, and communicating
project status at any time. Under AB 1171, the Legislature gave
Caltrans a budget of approximately $5.1 billion, including a
$448 million program contingency reserve. However, Caltrans
has not updated the projected program costs regularly to assess
whether it is staying within the budget that AB 1171 established.
In particular, Caltrans has not regularly updated its estimates
of support costs needed for the life of the program and has not
reassessed its program contingency reserve. Regularly updating
internal cost estimates would allow Caltrans to prepare a
detailed overview of the program that includes estimated capital
and support costs for all bridges, and contingency reserve
amounts. This overview, which would keep program managers
aware of program-wide costs, should be updated regularly or
as signifi cant changes become known. Had Caltrans regularly
5500 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5511
updated and monitored the program’s cost, it would have
recognized earlier that the program was exceeding its budget
under AB 1171.
In addition to cost estimating, the PMBOK Guide emphasizes the
importance of controlling changes to the project budget as part
of effective cost management. We found that Caltrans follows its
internal policies and procedures when issuing contract change
orders that modify original contracts and increase project cost.
Caltrans Does Not Regularly Update Cost Estimates for the
Whole Program
Although it prepares monthly estimates of costs on projects
under construction, Caltrans lacks a regularly updated overview
that includes actual costs, anticipated costs, and contingency
reserves from a program-wide perspective. The PMBOK Guide notes
that few projects run exactly according to plan, and that changes
may require new or revised cost estimates or analyses of alternative
approaches. Also, Caltrans’ project management handbook notes
that effective cost management requires project managers to
regularly compare actual expenditures to planned expenditures
at the level used in budget development. Further, FHWA strongly
recommends development of a monthly cost, schedule, and status

the cost estimates for April 2001. After AB 1171, he says estimates were updated
AB 1171 in April 2001. based on the specific milestone activities of individual contracts.
Such milestone updates include the advertisement of a contract,
a supplemental funds approval for a construction contract,
or the completion of a construction contract. Caltrans has
maintained the budget on a program basis and adjusted the
individual contract budget, if required, based on information
provided from a milestone for each contract. Caltrans manages
the approved budget as set forth in the funding legislation and
works to maintain this budget by mitigating potential risks that
may affect the program budget. Nevertheless, the director says
that a change in the law effective for 2004 requires Caltrans
to begin reporting the program’s status to the Legislature each
quarter, therefore, Caltrans is implementing a process to update
program-wide costs each quarter.

We recognize Caltrans has existing processes and procedures for
managing project costs, including estimating and controlling
costs, and prepares reports and cost estimates. On projects that
are under construction, the construction division at Caltrans’
headquarters prepares monthly toll bridge status reports that
include the following status information: the project’s original
contractual cost, bid amount, total paid to the contractor,
approved and pending contract changes that would increase the
project’s cost, potential additional costs from contractor claims
for reimbursement, and the percentage a project is complete
in dollars and time. According to the assistant construction
coordinator for the office of toll bridges at Caltrans’ construction
division, the reports are an oversight tool to assist Caltrans’

indicate the potential for large cost increases or time delays.
Caltrans could use its status reports as a basis for a program-wide
summary of costs and projected expenditures, integrating the
information into a program-wide summary on a regular basis for
use by Caltrans’ management.
Caltrans Did Not Regularly Reevaluate the Program’s
Support Costs
Proper tracking of support costs is important because they
represent 17 percent of the program’s budget (excluding the
contingency reserve) that AB 1171 established in 2001. However,
until recently, Caltrans did not regularly track whether its
support costs, set at $796 million in AB 1171, were projected
to stay within budget. Thus, during fiscal years 2002–03 and
2003–04, Caltrans lacked the information needed to identify
cost increases that occurred before the estimate for total support
costs jumped from $796 million under AB 1171 to $1.352 billion
in August 2004. However, as of October 2003, Caltrans’
accounting records showed that it had spent $612 million in
support costs since the program began. In November 2003,
Caltrans reported to FHWA that it was reducing its support
5522 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5533
cost budget to $766 million, leaving only $154 million to pay
support costs through 2011. If Caltrans had been updating its
estimates of support costs regularly, it would have known at that
time that its remaining budget of $154 million for support costs
over the remaining eight years of the program was insufficient.
At its 2003 usage rate of $8 million per month, Caltrans would
have spent its remaining support cost budget of $154 million by
June 2005.
Further, Caltrans provided us documentation of its August 2004
estimate of support costs for the program, showing that it
expected $713 million of the $796 million budgeted to be
consumed by June 30, 2004. According to the project control
manager charged with overseeing support costs estimates, the
project control unit for Caltrans’ District 4 Office prepared a
detailed estimate of total support costs needed for the remainder
of the program in March 2004, but he was not aware of Caltrans
completing such support costs estimates for fiscal years 2002–03
or 2003–04. He indicates developing the current total support
costs estimates without the benefit of a post-AB 1171 estimate.
This manager also indicates that Caltrans is updating the current
methodology for estimating support costs and plans to use it
again in fiscal year 2005–06.
It is difficult to understand how Caltrans did not know that
It is difficult to understand it would overspend its support cost budget of $796 million in
how Caltrans did November 2003, much less support its assertion that it would

5544 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5555
Caltrans Had Not Regularly Reevaluated the Program’s
Contingency Reserve Nor Accounted for Potential Cost Increases
Because Caltrans reevaluates the program’s contingency
reserve infrequently, its August 2004 report includes the first
reevaluation of the program’s contingency reserve since AB 1171
became law in October 2001. Yet, during this three-year gap,
Caltrans had several signs that its program contingency reserve
was insufficient to cover cost overruns. Without a regularly
updated contingency reserve figure, program managers lack
critical information to mitigate estimated or actual cost increases
and the information to make a timely appeal for additional
funding from the Legislature.
In November 2003, Caltrans reported to FHWA that it would
use $326 million of its $448 million program contingency
reserve to offset cost overruns, leaving only $122 million to be
allocated to future cost overruns. However, Caltrans announced
to the Legislature in its August 2004 report that the program
contingency reserve should be increased to $900 million. In
other words, as shown in Table 3 on page 19, after Caltrans
allocates the entire AB 1171 contingency reserve of $448 million
to cover a portion of the $2.768 billion in projected cost
increases over AB 1171, it estimates it will need $2.32 billion
of additional project funding plus a $900 million program
contingency reserve, for a total need of $3.22 billion.
In addition, the Caltrans’ cost estimates initially drawn up
A joint effort by Caltrans, for the August 2004 report significantly underestimated the

$8.3 billion, including a and the commission, Caltrans issued its August 2004 report
$900 million contingency projecting total program costs of $8.3 billion, including a
reserve. $900 million contingency reserve. The joint review resulted
in several adjustments. For example, according to supporting
documentation for Bechtel’s August 2004 cost review, Caltrans
did not account for $452 million in potential future capital
costs associated with adjustments to reflect increased prices
for steel and concrete, contractor’s time-related overhead and
mobilization, and escalation costs for several projects. This
includes escalation for certain projects where construction had
not yet begun. Escalation for these projects is important because
there may be increases in costs due to inflation, delays, and
other factors that prudent contractors will take into account
when preparing their bids or reimbursement requests. Also, the
5544 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5555
joint review determined that a $900 million contingency reserve
was more appropriate than the $223 million contingency reserve
that Caltrans initially estimated.
Caltrans Generally Follows Its Internal Contract Change
Order Policies
Caltrans generally follows its internal contract change order
(change order) policies and procedures when paying contractors
for work that is outside a construction contract. Caltrans
issues change orders to make changes to original contracts,
paying for changes with contingency reserves. Caltrans may
prepare change orders to adjust contract plans or specifications,
adjust the contractor’s compensation, clarify contract terms,
implement a cost reduction proposal, direct the contractor to
do extra work, or resolve disputes or potential claims with a
contractor. Caltrans’ construction manual sets forth policies
and procedures for preparing change orders, describing required
approvals and concurrences, and procedures for different types
of payment methods and performing cost estimates. We found
that Caltrans complied with its internal policies and procedures
Caltrans complied with when we reviewed a sample of 20 change orders with a value
its internal policies and greater than $1 million for the Richmond-San Rafael Bridge and
procedures in our sample skyway projects and greater than $300,000 for the west approach
of 20 change orders. project. In addition, Caltrans performed an appropriate
assessment of each change order’s impact on the overall project.
Project construction personnel determine if the proposed change
is within the scope of the original contract, evaluate the effect
of any time adjustment on project completion, and consider
if contingency reserve balances are sufficient to pay for the
change. Caltrans allows several different methods to determine
how much it will pay on a change order. Caltrans’ resident
engineers may choose to pay the change order for contract
items at contract prices or with adjustments to contract prices.
For extra work, the resident engineers may negotiate an agreed
unit price or a lump sum amount. They also may make a force
account estimate, in which Caltrans agrees to reimburse the
contractor by adding specified mark-ups to the actual costs of
material, equipment, and labor. Caltrans policy considers the use
of a force account payment, which does not lock the contractor
to set prices, to be the least preferred method of determining
payments for a change order. It requires resident engineers
to make every effort to adjust contract prices, or negotiate an
agreed price, which locks the contractor to that unit price or
lump sum amount, before resorting to this method.
5566 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5577
Caltrans used the force account payment method exclusively
or primarily in 11 of the 20 change orders we reviewed. A
supervising transportation engineer from the skyway project
and the project manager over the Richmond-San Rafael Bridge
and West Approach retrofits explained that the force account
method was used to determine the extra work costs in nine of
these 11 change orders because Caltrans could not estimate the
work within reasonable limits of accuracy or because they could
not negotiate an amount with the contractor. Two change orders
paid for traffic control, which Caltrans pays for at actual cost.
Nevertheless, Caltrans personnel are required to check extra work
bills submitted by the contractor for appropriate rates and allowable
items before approving force account payments, a process that
should protect Caltrans from overpaying for change orders.
To assist in resolving disputes and potential claims on which
Caltrans and a contractor cannot agree, Caltrans and the
contractor may establish a dispute review board at the beginning
of a project to review both parties’ positions and provide
recommendations to resolve disputes. The dispute review
board—an individual representing Caltrans, the contractor, and
a jointly selected member—initially makes recommendations
on the merits of the dispute. If requested by either party, it
recommends guidelines for determining compensation. Its
recommendations are not binding, however, and either party
may ask the board to reconsider its rulings if new evidence is
submitted. All three projects we reviewed had set up dispute
review boards, but none of the change orders we tested has
dispute review board rulings. According to the East Span project
manager, Caltrans uses the dispute review board as a last resort,
when dispute or potential claim resolution is unsuccessful.
Further, she indicates that Caltrans hopes to resolve most issues
before the dispute review board’s involvement, so Caltrans refers
only the most contentious issues to the dispute review board.
CALTRANS DID NOT EMPLOY GOOD
COMMUNICATIONS MANAGEMENT, RESULTING
IN THE FAILURE TO REPORT COST OVERRUNS TO
STAKEHOLDERS IN A TIMELY FASHION
Caltrans failed to keep its stakeholders informed of relevant
changes in its estimates of program costs and cost overruns on
a reasonable and timely basis. Although state law requires regular
reporting to the Legislature, Caltrans did not provide a status
report on the program for 2003 or the first half of 2004 until
August 2004. There were multiple indicators that the program
5566 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5577
would experience large cost overruns during 2003 and the
fi rst half of 2004, yet Caltrans failed to inform the Legislature
through its statutorily required reporting. Caltrans had strong
indications that the program’s costs would exceed the AB 1171
cost estimates as early as November 2003, when it provided
its annual fi nancial plan to FHWA. However, its fi nancial plan
contained information that did not refl ect its
internal cost estimates, and thus understated the
extent of the cost overruns. Moreover, Caltrans

Caltrans Failed to Report the Program’s Status and Cost
Overruns to the Legislature, as State Law Requires
Although state law requires Caltrans to periodically report the
program’s status and notify the Legislature of program cost
overruns, Caltrans did not report cost overruns it should have
known of until they were staggering. After submitting no status
report for 2003 or the fi rst half of 2004, Caltrans reported to
the Legislature in August 2004 that the program’s costs would
greatly exceed its funds. With the sole bid for the signature
span’s superstructure expiring on September 30, 2004,
Caltrans gave the Legislature about six weeks to develop a
funding solution to the $3.2 billion cost overrun. Had Caltrans
kept it better appraised of the program’s estimated costs,
the Legislature could have better considered how to address
and fund cost overruns as they occurred rather than having
to suddenly address a $3.2 billion cost overrun. This earlier
5588 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5599
notification could have come as early as November 2003, when,
as discussed here, Caltrans had strong indications that the
program’s cost would exceed the AB 1171 cost estimates.
Under the Streets and Highway Code (code), Caltrans is required
to provide program status reports to the Legislature. Through
2003, the code required annual reporting; beginning in 2004 the
law was changed to require quarterly reports of the program’s
status. These quarterly reports are supposed to include the
following items:
• The status, including details, of each toll bridge project.
• The baseline budget at the time of AB 1171.
• An updated budget and expenditures to date for support and
capital outlay costs.
• A comparison between the baseline and the updated budget.
• A summary of milestones achieved, issues identified, and
actions taken to address those issues.
In addition, the code requires that if Caltrans “determines
that the actual costs exceed the [budget provided in AB 1171,
Caltrans] shall report to the Legislature within 90 days from the
date of that determination as to the difference and the reason
for the increase in costs.”
However, Caltrans submitted no status report for 2003 or for the
Caltrans submitted no first quarter of 2004. As mentioned earlier, Caltrans did submit
status report for 2003 a report to the Legislature in August 2004 to meet the statutory

According to its director, with the new quarterly report
requirements established by Chapter 525, Statutes of 2003—
Assembly Bill 1717 (AB 1717)—Caltrans elected to include the
status information for 2003 in the first quarterly report for
2004. Caltrans intended to submit the first quarterly report
for 2004 by May 2004 consistent with past practice. Previous
annual reports had been submitted in April 2001, March
2002, and May 2003. The director further stated that it was
assumed internally that the annual report requirement was
replaced by the new quarterly report requirements in AB 1717
5588 California State Auditor Report 2004-140 California State Auditor Report 2004-140 5599
and that submitting the first quarterly report with appropriate
status information would suffice to meet the requirements of
the statutes. Caltrans made a conscious decision that given
the imminent bid opening of the contract for the signature
span’s superstructure due on May 26, 2004, and the dynamics
of the bidding environment and market prices for steel and
concrete, submittal of a quarterly report in May 2004 would lack
meaningful detail to report before confirmation of the detail of
the bid. The director said that, after the bid opening, Caltrans’
speculation was replaced with certainty that the bid would
cause the program to exceed the AB 1171 program budget and
that Caltrans was then obligated to report within 90 days to the
Legislature that the program’s actual costs would exceed the
AB 1171 budget. The director added that after the bid opening
and during the subsequent detailed program cost review during
June and July 2004 with the commission and Bechtel, Caltrans
was able to address the requirements of the 90-day report more
meaningfully. According to the director, Caltrans’ August 2004
report to the Legislature was intended to cover the time period
since the previous annual report and the first two quarterly
reports required by AB 1171.
Nevertheless, according to our legal counsel, Caltrans was still
obligated to submit an annual report for 2003 despite the code’s
change to require quarterly reporting commencing with 2004.
Moreover, the legislative intent was clearly to require more
frequent reporting commencing with 2004 and not to relieve
Caltrans of its obligation to provide an annual report for 2003.
Further, our legal counsel indicates that Caltrans was required
to begin reporting quarterly during 2004, with the first report
covering January through March 2004. In addition, as shown in
the next section, Caltrans should have known of large potential
cost overruns as early as November 2003 that should have
caused it to report that the program was over budget, for the
same reason as it did later in August 2004.
Caltrans Should Have Known Significant Cost Overruns Were
Likely When It Reported the Program’s Status to the Federal
Government in November 2003
Under federal law, entities receiving federal funds for a project
with an estimated cost of $1 billion or more must submit
a financial plan by November 15 of each year to FHWA.
Caltrans’ financial plan that it submitted to the FHWA in
November 2003 showed that the program’s projects were
exceeding AB 1171 cost estimates and that there was less
6600 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6611

reserve of $122 million program was over budget by $3.2 billion related to the signature

to the Legislature that the to the FHWA that “The cost data in the Financial Plan provide
program was over budget an accurate accounting of costs incurred to date and include a
by $3.2 billion. realistic estimate of future costs based on engineers’ estimates
and expected construction cost escalation factors.” If Caltrans
had performed the work necessary to support statements in its
certification to FHWA—such as computing the needed support
costs or determining the necessary contingency reserve for the
remainder of the program (which it later performed for the
August 2004 report)—this report should have caused Caltrans to
notify the Legislature of the potential for program cost overruns,
for the same reason as it did later in August 2004.
According to its director, Caltrans disagrees that information
in the FHWA report required Caltrans to notify the Legislature
of cost overruns for the program. He indicates that Caltrans’
report to FHWA said the signature span’s superstructure was
still in advertisement, the East Span schedule recently had
been extended with the readvertisement of the contract for the
signature span’s marine foundation, which included provisions
to add one year to the construction duration, and the financial
implications of the Richmond-San Rafael Bridge construction
contract had not been evaluated fully.
The director said the impact upon support costs had not been
evaluated because the schedule extension of the East Span was a
recent event. According to the director, because of the dynamic
nature of these ongoing events, Caltrans had not concluded in
November 2003 that cost increases in the program would exceed
the AB 1171 budget and contingency limitations, and, as such,
was not required to report to the Legislature.
However, as shown in Table 6 on page 64, Caltrans had ample
information in November 2003 to determine that program
costs would exceed its AB 1171 budget. In its November 2003
financial plan, Caltrans estimated total project costs at
$4.963 billion, $326 million greater than the AB 1171 budget of
$4.637 billion. Caltrans’ financial plan caused FHWA to question
several issues regarding the program’s funding.

executives the importance sent a letter to Caltrans with its concerns. In February 2004, to
of disclosing any address FHWA’s comments and questions, Caltrans supplied a
knowledge of potential breakdown of program costs, indicating the program had total
cost overruns related cost overruns of $563 million. Caltrans told FHWA it would use
to the East Span to the $237 million in projected savings and $326 million from the
federal government and program contingency reserve to pay for these cost overruns.
other stakeholders. However, these savings had almost evaporated by the time
Caltrans reassessed the program’s viability for its August 2004
report. For example, Caltrans indicated that it could reduce
support costs by $30 million by using fewer consultants
to supplement Caltrans employees assigned to oversee the
program. However, in August 2004—six months after it reported
this $30 million in support cost savings to FHWA—Caltrans
indicated that it needed additional funding of $556 million
to fund future support costs. Further, Caltrans indicated it
could achieve savings on the current East Span by reducing
estimated costs by $44 million for the demolition of the East
Span and $56 million for the Oakland touchdown. However, in
August 2004, Caltrans increased estimated costs for these projects
over the figures it reported to FHWA in February: $145 million
for the East Span demolition and $147 million for the Oakland
touchdown. Caltrans did not report any of these figures to the
Legislature until the August 2004 report as part of an even larger
cost overrun. This oversight is especially troubling because
Caltrans had committed 73 percent of its program contingency
reserve to projects under construction and not yet received a bid
for the signature span’s superstructure, which proved to be the
most expensive piece of the entire program. Further, Caltrans
could not provide us with documentation of the methodology
and calculations behind the cost savings it reported to FHWA.
In its January 2004 letter, FHWA also expressed concern that
the program had virtually no contingency reserve. The chief
deputy district director for the toll bridge program indicated
that Caltrans and FHWA met several times to discuss FHWA’s
concerns. In its February 2004 response, Caltrans answered
each of FHWA’s questions and provided additional cost
detail. Caltrans’ response clarified that the program overall
had a program contingency reserve of $448 million and that
$326 million of that amount would be used to offset program
6622 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6633
cost overruns, leaving a remaining balance of $122 million
to fund any future cost overruns. FHWA also asked what
alternatives would be available to address a funding shortfall.
Caltrans responded that its existing authority under AB 1171
allowed it to issue GARVEE bonds or notes, which are tax-
exempt financial instruments repaid by future annual
federal appropriations for federal aid transportation projects.
Although these notes quicken the receipt of cash, they are not
a supplemental funding source. Caltrans also indicated several
funding alternatives existed requiring legislative approval,
including raising the toll on the bridges by $1 to generate an
additional $120 million annually that could leverage more than
$1 billion in additional debt, removing the cap on existing
bonds to provide additional bonding capacity, or extending the
terms on the existing bonds beyond 2038. FHWA subsequently
accepted Caltrans’ response later in February 2004.
Caltrans’ response failed to inform FHWA of the likely extent
of estimated program costs because the amount Caltrans
already had spent at the time of its report was close to or
higher than some estimates, yet the program was years from
completion. Title 23, U.S. Code, Section 106, requires that the
annual financial plan for projects with estimated costs of at
least $1 billion be based on detailed annual estimates of the
cost to complete the remaining elements of the project and
on reasonable assumptions of future increases in the cost to
complete the project. However, based on internal Caltrans
reports and the amounts that it eventually reported to the
Legislature in August 2004, Caltrans should have known that
In its November 2003 the program was experiencing cost overruns. Table 6 on the
report to the federal following page shows the progression of cost estimates for the

estimate for the same capital costs of the signature span bid) not only that it would

need $748 million more than AB 1171 estimates. Thus, in
six months it determined that the information it reported to
FHWA was incorrect by $878 million for these three areas of
purported savings.

† Caltrans provided only the total capital costs for the signature span contracts in its February 2004 response to FHWA. The
director indicates that this was done to maintain the comparison of the original FHWA submittal documents to subsequent
annual financial plan updates to FHWA.
‡ Caltrans indicates that it estimated the contract at $812 million in October 2003, which was its update to the engineer of
record’s estimate. The $812 million includes supplemental work, state furnished items, and contingencies totaling $86 million.
§ This estimate is from Caltrans’ bridge cost estimating specialist and according to the director is speculative.
ll We requested this information, but Caltrans did not provide it.
# According to the director, Caltrans maintains a running contingency balance per awarded contract. Caltrans did not, however,
keep a running balance of commitments against the program contingency reserve.
** In its response to FHWA, Caltrans showed amounts that were $1 million to $2 million different.
As shown in Table 6, significant differences exist between the
amounts Caltrans reported to FHWA and the amounts contained
in Caltrans’ internal reports at or near November 2003, when
Caltrans prepared the FHWA report. We discuss the reasons for
these differences in the following sections. It is important to
note that with Caltrans reporting a remaining balance in its
contingency reserve of only $122 million and without having
received a bid for the superstructure, nearly any one of the
following differences was significant enough to cause Caltrans
to report to the Legislature that funding for the program was
insufficient to meet future needs.

Caltrans’ Estimate for Support Costs for the Remaining Eight
Years of the Program Was Understated Significantly
In its November 2003 report to FHWA, Caltrans significantly
understated an estimate of the support costs it would incur
over the program’s remaining eight years. As shown in Table 6,
Caltrans indicated to FHWA that its program support costs
would total $766 million, a $30 million reduction from the
AB 1171 amount. In response to FHWA’s questions, Caltrans
said it could produce savings of $30 million in support costs
to offset increases in other program costs. However, as of
October 2003, Caltrans’ accounting records showed that it had
spent $612 million in support costs since the program began,
leaving only $154 million to pay support costs through 2011.
At this point, Caltrans should have known that its support costs
over the remaining eight years of the program would be much
higher than $154 million and that it should revise its estimate
upward, not downward. By November 2003, Caltrans reported
to FHWA that it had extended the completion date of the project
by four years beyond the year 2007 for which AB 1171 provided
funding for support costs. By October 2003, Caltrans already
had spent $612 million, thus the $154 million left in its estimate

November 2003 through December 2011.
Caltrans’ Internal Estimates for the Signature Span’s
Superstructure Showed the Potential for Increased Costs Well
Before the May 2004 Bid Was Received
Caltrans’ internal estimates for the cost of the signature
span’s superstructure also were increasing and should have
led Caltrans to alert the Legislature that program costs would
6644 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6655
be higher than the AB 1171 estimates. When it advertised the
superstructure for bid in February 2003, Caltrans indicated
to bidders that the contract’s “call-out number” (used to give
bidders a general idea of the contract’s scope) was $733 million.
This amount was about $264 million more than the amount
that Caltrans budgeted for the superstructure at the time
of AB 1171. However, internal analyses show that Caltrans
had indications that this figure was understated significantly.
As shown in Table 7, these internal analyses show that, based
on a consultant’s mock bid, there were indications as early as
August 2002 that the superstructure bid could be as high as
$934 million. Also, in December 2003, the assigned Caltrans
bridge cost estimating specialist computed an estimated cost
of $1.036 billion. Further, shortly before the May 2004 bid
opening, an internal estimate of the bid amount was nearly
$1.3 billion, which was slightly less than the actual bid amount.
The director provided the following clarifying remarks about the
Although discounted estimates in Table 7. He stated that the mock bid estimate was
by Caltrans, estimates prepared by a different consultant in an abbreviated timeline
of its bridge cost and lacked a detailed analysis. Therefore, Caltrans determined
estimating specialist and that this estimate did not justify a revision. Subsequently,
a consultant proved more Caltrans did revise the engineer of record’s estimate in May,
accurate than its official June, and October 2003 to reflect the changes made by addenda

signature span. if the addenda at that time had ameliorated the cost issues
created by the changing construction market. This cost scenario
was developed in part based on the recent single bid received for the
marine foundation of the signature span. Further contract changes
were made before bid opening. Accordingly, Caltrans determined
that this cost scenario did not justify a revision to its October 2003
mathematical update to individual contract line items.
The director further said that during the last few months of the
advertisement period for the superstructure contract (March
and April 2004), contractors and subcontractors were indicating
that increasing market prices would affect their bid amount.
This information was limited in nature and consisted of calls to
contacts in the fabrication and steel industries, so its accuracy
was viewed as unreliable. The director said Caltrans was unable
to confirm this information until an actual bid was received.
Due to the anticipated competition between bidders, Caltrans
was uncertain what the bidding environment might yield at
bid opening. As a result, the director indicates that Caltrans

did not update its October 2003 estimate due to the continued
improvements to the contract that it made through the
addendum process during the advertisement period. Caltrans
based these changes on prospective bidders’ feedback on issues
such as contract time, cash flow, bonding, and constructibility.
The actual impact that the spike in steel prices would have on
the contract remained uncertain, as the contractor would not
actually purchase the plate steel until at least one year from
the contract award date. Finally, the director stated that the final
contract contained significant improvements from the original
contract from which the engineer of record produced an estimate.
However, by continuing to use cost estimates that were
being called into question by other factors, Caltrans gave the
impression that the sole bid for the superstructure was far above
its expectations. The value analysis by another consultant and
the even higher estimates of its bridge cost estimating specialist
were discounted by Caltrans in favor of its official estimate.
6666 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6677
Yet their increasingly higher estimates of the superstructure’s
cost—in the range of $1 billion or more—proved to be more
accurate. Caltrans also states that the higher estimates could not
be used because of limited or incomplete analysis, or because
they were overtaken by events in the marketplace. However,
given an environment of changing materials prices, contractor
feedback, and other strong indications of a high bid, Caltrans
should have devoted the time and staff to produce a detailed
up-to-date cost estimate rather than rely on its older estimate.
The Program Contingency Reserve Was Almost Completely
Committed in November 2003
The program contingency reserve that Caltrans reported to
FHWA was $122 million of the original $448 million budgeted
in AB 1171. This balance seems grossly insufficient for several
reasons, a primary one being that the bid for the signature
span’s superstructure was not yet received and Caltrans’
internal estimates indicated that the superstructure would
cost significantly more than expected. Further, the skyway
section of the East Span was only 31 percent constructed, and
likely to see significant cost escalation during construction, as
Caltrans had found on other bridge projects. Less than a year
later, in its August 2004 report, Caltrans concluded that the
program needed a much larger contingency reserve, suggesting
that it be replenished to $448 million and increased by an
additional $452 million, to raise the total contingency reserve to
$900 million. Given the $122 million figure in the FHWA report,
Caltrans should have reported to the Legislature in 2003 that the
program had a serious shortage of contingency reserves.
The Estimated Cost for the Richmond-San Rafael Bridge Was
Higher Than Caltrans Reported to FHWA
Caltrans underreported to FHWA the estimated costs for the

a total potential cost probable amounts Caltrans would need to pay on the
of $613 million to contractor’s pending reimbursement claims. As a result,
$648 million. in October 2003 Caltrans expected it would need to find
$43 million to $78 million to cover the cost of this bridge
6688 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6699
before considering the need for additional contingency reserves
for possible future claims. Although there were sufficient funds
remaining in the program contingency reserve to cover these
costs—$122 million as noted previously—funding them would
be a significant drain and reduce the amount of contingency
reserve available to other projects in the program. Moreover, in
its August 2004 report, Caltrans reported that the Richmond-
San Rafael Bridge would incur additional cost overruns, which
would raise the total estimated capital outlay cost for the project
to $780 million.
The Skyway Was Less Than Half Constructed and Was Likely to
Require Additional Funding to Cover Unforeseen Cost Increases
Caltrans had sufficient indications that the skyway’s costs
would continue to increase because it was relatively early in
the project’s construction. As of November 2003, the skyway
was only 31 percent constructed, yet its projected cost was
$302 million to $321 million over the AB 1171 estimate, and
Caltrans reported having only a $20 million contingency reserve
balance for the project. Given that significant work remained
on the skyway, Caltrans should have known that costs would
increase, causing a further drain on the program’s contingency
reserve. In fact, Caltrans stated in its August 2004 report that the
skyway’s estimated cost had increased $186 million beyond the
amount it reported to FHWA, with the total estimated capital
cost for the skyway rising to $1.293 billion.
Caltrans Did Not Keep the Commission Informed of the
Program’s Cost Overruns
Caltrans has not updated the commission regularly on the
program’s cost overruns for ongoing projects and on changing
cost estimates for the signature span. Such omissions are
especially unwise because the toll bridges are an essential
part of the commission’s regional transportation plan and
the San Francisco Bay Area’s toll payers, whose payments are

by raising new revenues.
6688 California State Auditor Report 2004-140 California State Auditor Report 2004-140 6699
According to the commission’s manager of bridge and highway
operations, the only updates that Caltrans provided the
commission were the statutorily required reports that Caltrans
prepares for the Legislature. However, as noted previously,
Caltrans did not prepare a report for 2003, and its only report in
2004 was the August 2004 report. Further, the manager stated
that the first time Caltrans officially disclosed to the commission
that cost estimates for the seismic program would exceed the
AB 1171 estimates was a meeting between Caltrans and the
commission on June 2, 2004, or seven days after Caltrans opened
the bid for the signature span’s superstructure. At that meeting,
Caltrans disclosed that it was estimating a total cost of the
program at $6.8 billion, $1.7 billion more than in AB 1171. Also
at that meeting, Caltrans requested that the commission assist
Caltrans in the overall review of the program. The commission
then hired a consultant, Bechtel, to review the reasonableness of
the Caltrans cost forecast for the program. Subsequently, Bechtel
issued a report in August 2004 that supported Caltrans’ revised
cost forecast of $8.3 billion for the program.
By contrast, Bechtel keeps the commission updated on the
progress Caltrans makes on toll bridge work done as part of
the Regional Measure 1 (measure 1) program. Bay Area voters
approved measure 1 in November 1998 to authorize a toll of
$1 for all seven state-owned toll bridges. The toll revenues
that measure 1 generates are for certain highway and bridge
improvements, public transit rail extensions, and other projects
designed to reduce congestion on the toll bridges. Caltrans
Bechtel’s monthly reports manages these projects for the commission, with the largest
on construction projects project being the new Benicia-Martinez Bridge, which will
in the measure 1 program cost more than $1 billion. The commission contracts with
alert the commission Bechtel to monitor the measure 1 projects. Bechtel provides
to potential cost and the commission a monthly progress report within 23 working
schedule problems. days after each month. Focusing on monitoring project cost and
schedule performance as measured against approved budget
and schedule milestones, these monthly reports provide a
mechanism to alert the commission promptly to potential cost
and schedule problems.
According to the commission’s bridge and highway operations
manager, the commission sees a critical need for new oversight
and management processes for the Toll Bridge Seismic Retrofit
Program. In addition to implementing an ongoing monthly
reporting system for the program, an improved management
and oversight process should go beyond reporting to include
processes to accomplish the following goals: anticipate and
7700 California State Auditor Report 2004-140 California State Auditor Report 2004-140 7711
identify construction issues early, allow issues to be reported
to management and resolved as early as possible, evaluate and
review construction change orders, and update and report cost
and schedule estimates on a continuous basis.
RECOMMENDATIONS
To ensure that it properly manages the risks associated with
these construction projects, Caltrans should continue to revise
its risk management practices, but ensure that its efforts include:
• Establishing comprehensive risk management plans that
clearly define roles and responsibilities for risk management
and addresses how Caltrans will identify and quantify project
risks, implement and track risk response activities, and
monitor and control risks throughout the life of the project.
• Quantifying the effect of identified risks in financial terms.
• Developing and maintaining documents to track identified
risks and related mitigation steps.
To ensure that it follows generally accepted practices for cost
management, Caltrans should:
• Regularly update its estimates of capital and support costs.
• Regularly reassess its contingency reserves for potential claims
and unknown risks, incorporating information related to
risks identified and quantified through its risk assessment
processes.
• Regularly integrate estimates for capital, support costs, and
contingency reserves into a program-wide report.
To ensure that it follows generally accepted management
practices for communications management, Caltrans should:
• Submit quarterly status reports to the Legislature, as the law
requires.
• Ensure that reports to FHWA and other stakeholders reflect
current data and provide an accurate representation of the
program’s status.
7700 California State Auditor Report 2004-140 California State Auditor Report 2004-140 7711
• When key events occur, such as a bid opening for a major
project, quickly inform stakeholders how these events affect
the program’s overall budget and schedule.
The Legislature should consider revising state law to require that
Caltrans submit its quarterly reports within a certain period after
each quarter, such as 45 days, to ensure that the information
Caltrans provides is current.
Although the code specifies certain elements to include in
the quarterly seismic reports for the program, the Legislature
should consider changing state law to require that these reports
provide a program-wide summary of the program’s budget
status for both capital outlay and support costs. Specifically, the
report should contain the following project and program-wide
fiscal information:
• The baseline budget as provided for in state statute.
• Actual expenditures incurred to the end of the quarter.
• The current forecast of expenditures expected for the
remainder of the program.
• Amounts of pending change orders, notice of pending claims,
and other contractor claims outstanding at the end of the
quarter and those that Caltrans has received within 10 days of
submitting its quarterly report.
• A comparison of the baseline budget provided in statute
compared with expenditures incurred to the end of the
quarter; the current forecast of expenditures for the remainder
of the program; and outstanding change orders, notice of
pending claims, or other contractor claims.
• Commitments against both project and the program level
contingency reserves, along with a realistic assessment of the
adequacy of project and program contingency reserves.
• Contracts for projects that Caltrans has not yet entered
into and the current estimates of the contract values by its
engineer of record and bridge cost estimating specialist.
• A detailed description along with specific financial estimates
of any other events or issues that could have a financial
impact on the program.
7722 California State Auditor Report 2004-140 California State Auditor Report 2004-140 7733
• Certifications by the Caltrans director and deputy director
of finance that the information in the quarterly report is an
accurate and complete status and forecast of the program’s
financial condition.
• Certification by an independent engineering consultant that
the information in the quarterly is an accurate and complete
status and forecast of the program’s financial condition.
In reviewing the options that Caltrans presents for completing
the East Span, the Legislature should consider requesting that
Caltrans provide sufficient detail to understand the financial
implications of each option. Specifically, this detail should
include for each option a breakdown of the costs for capital
outlay, support, and contingencies at the project and program
level. Further, to place each option in perspective, Caltrans
should provide a reconciliation of each option to the figures it
presented in its August 2004 report to the Legislature.
We conducted this review under the authority vested in the California State Auditor by
Section 8543 et seq. of the California Government Code and according to generally accepted
government auditing standards. We limited our review to those areas specified in the audit
scope section of this report.

Elaine M. Howle*
State Auditor
Bureau of State Audits

Dear Ms. Howle:
Thank you for the opportunity to respond to your draft audit report, Department of Transportation:
Various Factors Increased Its Cost Estimates for Toll Bridge Retrofits and Its Program Management
Needs Improving (#2004-140). The Department of Transportation (Caltrans) response is attached.
As you know, Governor Schwarzenegger has committed to, and has already begun implementing
changes to, streamline operations and improve efficiency and effectiveness in State government. I
am pleased to see that your recommendations will assist us in achieving those goals. Moreover, I
am gratified that you have concluded that no funds appropriated for the Toll Bridge Seismic Retrofit
Program (TBSRP) were diverted for other uses, particularly given that this program has existed for
several years.
As you note in your report, the challenge of building large and complex bridges in locations
that have high seismic risk is very difficult and multi-faceted. Replacement of the East Span,
in particular, has been and continues to be one of the most complex engineering projects ever
undertaken and, as indicated in your report, has been adversely affected by factors both within
and beyond the control of Caltrans. The self-anchored suspension (SAS) component, or signature
span, which is the only one of its kind in the world, was a significant factor in the escalation of the
costs of the project. Recently, in fact, the Business, Transportation and Housing (BTH) Agency
convened an expert peer review team led by the Federal Highway Administration and composed
of notable engineering expert practitioners and academicians from other states to provide advice
on the decision whether to continue with plans to construct the signature span as part of the East
Span. This objective team of experts concluded that the SAS component was so complicated and
unique that there would continue to be significant risk of additional time delays and escalation of
costs.
The BTH Agency is wholly committed to improving oversight and management in the TBSRP in general,
and in the San Francisco-Oakland Bay Bridge (East Span) project, in particular. We recognize that
Caltrans has performed admirably in certain aspects of the TBSRP, such as retrofitting five of the seven
bridges under budget by a total of $48 million. We note, however, that the larger, more complex projects

require a different skill set, including greater emphasis on all project management components, such
as risk management. Therefore, we have already taken several definitive actions to assess particular
circumstances involving the East Span project, and to determine the best course of future action.
For example, once the scope of the issues regarding the funding for the East Span project was
discovered earlier this year, the BTH Agency assembled a work group to determine whether the
$878 million projected need for Capital Outlay Support (COS) was a reasonable estimate derived
through a credible process. The workgroup, incidentally, concluded that a credible process was
used to develop and validate the estimate, and that, by extension, the estimate was the best that
could be expected at the point in time it was developed. Further, recognizing the effect of COS on
the overall cost of the project, the BTH Agency has already formulated the scope of work for which
it will be engaging the services of an expert consultant to assess the process Caltrans uses to
estimate COS, and to provide recommendations for controlling COS on major construction projects.
Additionally, in line with your concerns regarding communications management, the BTH Agency
independently assessed the circumstances surrounding the submission of statutorily mandated
reports by Caltrans. We determined that, although Caltrans did not adhere to the requisite
schedule, sufficient evidence exists to support the conclusion that Caltrans did not attempt to
1
purposefully withhold TBSRP expenditure information from the Legislature. For example, reports
containing said information were regularly provided to the California Transportation Commission
(CTC), two ex-officio members of which are the chairs of the legislative transportation committees.
Further, the information was presented at CTC meetings for which advance agendas noting the
presentations were provided to key legislative committee staff and staff of the Legislative Analyst’s
Office, many of whom regularly attended the meetings. Although there is no justification for the
failure to provide timely reports to the Legislature, the above factors should mitigate any concern
that Caltrans failed to disclose the information altogether.
Finally, the BTH Agency has already contracted with a private consulting firm to conduct a supplementary
review of the project management process used in the East Span project. The results of the consultant’s
work will be submitted to an independent expert panel for review and comment prior to being issued to
the BTH Agency and Caltrans for use in improving the current process of project management.
I appreciate your recommendations for improving the manner in which Caltrans goes forward with
the TBSRP. The changes Caltrans intends to make are detailed in its response. Again, thank you
for the opportunity to respond to your draft audit report. If you need additional information, please
do not hesitate to contact me, or Michael Tritz, Chief of the BTH Agency Office of Internal Audits, at

Sacramento, CA 95814
Dear Secretary:
I am pleased to provide our response to the Bureau of State Audits’ (BSA) draft audit report
entitled, “Department of Transportation: Various Factors Increased Its Cost Estimates for Toll
Bridge Retrofits and Its Program Management Needs Improving.” The report correctly concludes
that the uniqueness of design and volatile markets for contractor services and materials coupled
with schedule delays and higher contingency estimates have led to a large increase in estimated
program costs. The report also reviews the Department of Transportation’s (Caltrans) project
management practices with primary focus on the East Span of the San Francisco Oakland
Bay Bridge (SFOBB), and cites the need for improvement in those practices. This letter
includes commentary on the overall content of the audit report, and a specific response to the
recommendations contained in the document.
In summary, I believe that Caltrans has attempted to manage the Toll Bridge Seismic Retrofit
Program (TBSRP) in a manner consistent with our standard practices, relying on our substantial
experience in working on capital construction projects. For five of the toll bridges included in the
TBSRP, Caltrans was able to complete the required retrofit of these bridges with a cumulative
savings of $48 million as compared to the budget established in AB 1171. Notwithstanding this
success, we acknowledge that there have been problems related to the design and construction of
the SFOBB.
Caltrans is working hard to correct identified deficiencies in our management practices, and we
appreciate the recommendations included in the BSA report that will assist in accomplishing that
objective. To provide additional assistance in this effort, the Business, Transportation and Housing
(BTH) Agency has engaged the services of a consulting group to review our practices and identify
factors that have contributed to material cost increases for this project. However, we have also
undertaken internal actions to provide for more cost-effective oversight, and I want to focus on
these activities in this response.
Before commenting on these activities, however, I want to clarify the Caltrans’ interpretation of cost
2
overruns versus cost increases. The audit report repeatedly refers to overruns in the TBSRP. From
our perspective, a cost overrun occurs after a project has been bid and a dollar amount allocated
8800 California State Auditor Report 2004-140 California State Auditor Report 2004-140 8811
Sunne Wright McPeak
December 10, 2004
Page 2
to finance that project. By way of example, the need to add $249 million to the budget for the
Richmond-San Rafael retrofit project after the initiation of construction constitutes a cost overrun.
Prior to bid and award, higher budget projections for a project translate to cost increases. Higher
projections for most of the east span projects that have not gone to construction have resulted in
cost increases.
With that clarification, it should be noted that numerous actions have been taken to mitigate bid
costs in excess of budgeted amounts for the TBSRP. When the bids came in over the engineer’s
estimate for the E2/T1 foundation project, Caltrans undertook several steps to reduce the cost of
that project, and the resulting re-bid resulted in a $30 million cost savings.
When Caltrans determined that the AB 1171 budget might be exceeded if the main span bid came
in significantly higher than the engineer’s estimate, it initiated a review of all possible options to
improve the bid package to reduce costs and to increase the potential for a bid within the AB 1171
limits. Numerous innovative management and contract requirements were applied to many of the
TBSRP east span contracts to encourage strong bid competition, lower bids, and minimize costly
delays during construction. Some of these include:
• Pier 7 of the Port of Oakland was obtained to provide office space for both Caltrans and the
Contractor near the work site as well as facilitate materials to the work area. By providing this
area, Caltrans has reduced contractor costs as well as provided for increased communication
with the contractor for faster resolution of issues.
• A formal design campus was required for the Contractor and Caltrans to work together closely
in the same office space to speed up the review and approval of time critical working drawings
and requests for information. An additional payment item to facilitate this early cost to
contractors was included. Plan approval delays can result in significant increases, especially
on a project with 15,000 to 25,000 shop drawings.
• A separate demonstration pile contract was initiated to test constructibility of piles resulting in
reducing bidder risk. The project identified risks that would have resulted in millions in cost
from delay once construction had begun.
• A revised mobilization specification provides for revised schedule of and limits on payments
for large and complex contracts. Also, a payment item was added to reduce the financing
costs of contractors to mobilize marine equipment to access the work.
• A corridor value analysis specification added a process whereby contractors from projects
along the east span corridor can meet with Caltrans to propose and discuss as a group ways
to accelerate the overall project and reduce costs.
• Design elements were revised for the bridge design to address concerns with available marine
equipment due to the hull restrictions of the Jones Act.
• Extensive review of welding specifications resulted in many revisions to improve
constructability and incorporate lessons learned from claims on other projects.
• Earthquake liability was capped to limit risk for contractors for cost of damages should a
seismic event occur.

• Low bids factoring in time as well as cost (A plus B bidding) were combined with incentives
and disincentives to challenge and encourage the contractor to do the work as quickly as
possible.
• Payment and performance requirements were reduced to an acceptable risk level. Caltrans
advocated legislation to allow changes to this requirement.
• A bidder compensation stipend specification encourages more competitive bids and partially
compensates them for the additional effort of preparing a bid.
• A table in the specifications was added to assist bidders in identifying submittals and their
review times, thus keeping submittals off of the critical path. An additional payment item for
accelerated working drawings was also added to limit delay during reviews.
• An intensive series of more than twenty-five informational and technical exchange meetings
were held for prospective bidders, small businesses and disadvantaged businesses to
enhance communication for constructability during the design and bid process.
• Anticipating bonding and insurance challenges, Caltrans sponsored a bill passed in 2003, AB
1745, that lowered bonding requirements for contractors on mega-projects such as the East
Span.
Caltrans is committed to take whatever actions are necessary to achieve an efficient and cost-
effective management structure that will ensure a high level of accountability for this important
project, and we will continue to look for opportunities to accomplish this.
I also want to respond in some depth to statements in the audit report that because mandated
statutory reports were not submitted on time, the Legislature was precluded from taking action to
resolve the budget issue related to the TBSRP. Further, I want to correct the inference that Caltrans
3
failed to disclose this information in an attempt to withhold cost information.
Admittedly, Caltrans did not provide certain required reports to the Legislature by the requisite due dates,
specifically, the annual report due at the end of calendar year 2003 (Streets and Highways Code Section
188.5(d)(1); Chapter 327, Statutes of 1997) and the first two quarterly reports required under AB 1717
by Assembly Member Dutra (Chapter 525, Statutes of 2004). Although there is no justification for failure
to provide timely reports to the Legislature, there are a few factors that mitigate the concern that the
information was not available and that Caltrans was willfully withholding this material.
4
The essential information that would have appeared in the reports to the Legislature was provided
in quarterly and annual reports to the California Transportation Commission (CTC), although none
of these reports prior to May 26, 2004, indicated that Caltrans was projected to spend more than
the budgeted amount included in AB 1171. Throughout calendar year 2003 and 2004, Caltrans
briefings before the CTC clearly laid out the status of the program and public discussion took place
over the concern that certain project bids exceeded engineers’ estimates that were used to establish
the AB 1171 budget for the program. In December 2003, the CTC reported to the Legislature in an
annual report that TBSRP costs seemed likely to increase beyond the original estimate, perhaps
even beyond the budgeted contingency fund. Specifically, the CTC indicated, “in September of 2003,
Caltrans reported its latest cost estimate for the toll bridge seismic retrofit program at $4.932 billion,
an amount that would require $295 million of the $448 million contingency…”
8822 California State Auditor Report 2004-140 California State Auditor Report 2004-140 8833
Sunne Wright McPeak
December 10, 2004
Page 4
Moreover, the same CTC annual report referenced the BSA’s August 2002 report on increased
costs for the toll bridge seismic retrofit projects by stating, “As reported to the Governor and the
Legislature by the State Auditor in August 2002, some increase now seems likely, perhaps even
more than the designated $448 million in contingency funds.”
With respect to the requirement contained in AB 1171 to report within 90 days if Caltrans
determines that the actual costs of the program exceed the amounts appropriated for the seismic
retrofit work, the audit report implies that Caltrans should have advised the Legislature as early as
November of 2003 that costs for the TBSRP were in danger of exceeding the AB 1171 budget. The
audit report references a November report to the Federal Highway Administration that cited upward
pressures in the construction market pointing to cost increases in the program. However, at the
time, this information was speculative, and Caltrans concluded that notification of the Legislature
was not required since the budget had not been exceeded and aggressive cost mitigation strategies
were being employed to bring the project in line with budget. While potential cost increases were
a concern, nothing was known for certain until the bid opening for the Self-Anchored Suspension
5
(SAS) main span on May 26, 2004. Until this time, Caltrans believed that, in the worst case
scenario, a plan to provide a larger contingency might have been warranted.
Caltrans took appropriate steps to meet the statutory notification requirement when the bid for the
main span project was opened in May of 2004. The Secretary of BTH joined Acting Director Tony
Harris immediately after the bid opening for a media briefing to announce to the public that award of
the SAS main span contract for the bid received would exceed the budget authority in AB 1711, and
Caltrans initiated a revision of report material to inform the Legislature that costs for the program
would exceed the AB 1171 budget.
Caltrans reported to BTH in mid-June that a re-analysis of the TBSRP showed a possibility of
an overall program cost increase of up to $1.5 billion. After several preliminary meetings with
Metropolitan Transportation Commission (MTC) in March through June of 2004, BTH and Caltrans
met in July with MTC to develop a process for agreeing on estimates for the program going forward.
It was agreed that Caltrans and MTC would work with Bechtel Infrastructure Corporation to reach
consensus on project and program estimates so that a reliable funding package could be pursued
and a joint funding proposal could be submitted to the Legislature.
At that time, the involved parties agreed that a complete review of all design options for the main
span should be considered to see if the program could be brought back in line with the AB 1171
6
budget. It was not until the end of July that enough analysis on prospective costs and options had
been conducted to conclude that there did not appear to be a way of completing the East Span
within the legislative budget, regardless of design alternatives. On August 16, 2004, Caltrans
submitted an updated status of the TBSRP to the Legislature. This document was intended to
satisfy the requirements for submittal of a 2003 annual report and the first two quarterly reports for
2004 as required by AB 1717.

The timely submittal of statutory reports is an appropriate issue for BSA to raise. In fact, since
my appointment as Director, I have implemented a monitoring system to provide information
regarding report deadlines and to track the progress of report preparation. I have made it clear to
my senior management that Caltrans will meet report deadlines and that I intend to hold managers
responsible for complying with these requirements. However, while previous reporting requirements
may not have been met, I am convinced that there was absolutely no intent on the part of Caltrans
to withhold information on the status of the TBSRP. Nonetheless, it is also my intent to review the
involvement of key personnel associated with this project to determine if there was any misconduct
or negligence on the part of any individual in terms of meeting the requirements of the law. If it is
determined that anyone was negligent in this regard, appropriate disciplinary action will be taken.
At this point, I would like to respond to the specific recommendations included in the audit report.
The report identifies the following findings and recommendations:
Chapter 1: Volatile Markets for Contractor Services and Materials, Schedule Delays and Higher
Contingencies Led to a Large Increase in Estimated Program Costs
This chapter generally covers the various reasons for cost increases and contains no
recommendations.
Chapter 2: Caltrans Project Management Practices Need Improvement
This chapter covers several important aspects of project management and contains three
recommendations.
Chapter 2 Recommendations:
1. To ensure that it properly manages the risks associated with these construction projects, Caltrans
should continue to revise its risk management practices, but ensure that its efforts include the
following:
• Establishing comprehensive risk management plans that clearly define roles and
responsibilities for risk management and address how Caltrans will identify and quantify
project risks, implement and track risk response activities, and monitor and control risks
throughout the life of the project.
Caltrans Response:
With the assistance of consultants, Caltrans has developed a Report on San Francisco-Oakland
Bay Bridge Quality Assurance and Risk Assessment. Caltrans will designate a dedicated Project
Risk Management Coordinator to support the Project Manager. The coordinator will:
8844 California State Auditor Report 2004-140 California State Auditor Report 2004-140 8855
Sunne Wright McPeak
December 10, 2004
Page 6
1. Facilitate the Risk Response Team of knowledgeable personnel and consultants working on
the SFOBB.
2. Regularly update, with the team, the risk assessment and prepare a risk response plan in
accordance with Caltrans Project Risk Management Handbook.
3. Arrange and conduct quarterly meetings of the Risk Response Team to reevaluate the
risks, revise the risk response plan, and determine whether the risk response plan is being
followed. The Project Risk Management Coordinator and Project Manager will ensure
that each person who is responsible for one or more of the risk responses is aware of and
understands their responsibility.
4. Complete an updated risk response plan following quarterly meetings. The updated plan
will be submitted to the Project Manager and Program Manager with an assessment of any
changes in risks, the progress in following the previous month’s risk response plan, and the
status of the contingency reserve balance.
As part of Caltrans quarterly reporting process, the Program Manager will submit to the District
Director, Chief Engineer, and Director the updated risk response plan that defines potential
scope, cost, and schedule issues related to risks and mitigation measures.
• Quantifying the effect of identified risks in financial terms.
Caltrans Response:
1. In accordance with Caltrans Project Risk Management Handbook, the Risk Response Team
will classify risks as “High Impact,” “Moderate Impact” and “Low Impact” through a “Qualitative
Risk Analysis.”
2. The Risk Response Team will estimate the most probable and credible financial impact of
each high-impact risk, should it occur.
3. Caltrans will utilize consultant and industry expertise as needed.
• Developing and maintaining documents to track identified risks and related mitigation steps.
Caltrans Response:
1. The Project Risk Management Coordinator will maintain records of the initial and quarterly
revised assessments, qualitative and quantitative analyses, quarterly risk response plans,
and assessments of progress in implementing the risk response plan.
2. The Project Manager will incorporate the risk response plan in the evaluation of project
budgeting and project control and monitoring activities.
3. Caltrans will utilize consultant and industry expertise as needed to supplement this process.

2. To ensure that it follows generally accepted practices for cost management, Caltrans should do
the following:
• Regularly update its estimates of capital and support costs.
Caltrans Response:
7
1. Capital Outlay cost estimates will be updated annually during design.
2. A revised Capital Outlay cost estimate (the “Engineer’s Estimate”) will continue to be
prepared before each contract is advertised.
3. Capital Outlay estimates will be updated by the Division of Construction quarterly for
contracts in construction.
4. Capital Outlay Support cost estimates will be updated quarterly by the Project Manager.
• Regularly reassess its contingency reserves for potential claims and unknown risks,
incorporating information related to risks identified and quantified through its risk assessment
processes.
Caltrans Response:
8
1. In accordance with Caltrans’ policies, the Division of Construction will assess the
adequacy of the contingency reserve on each construction contract quarterly.
2. The Project Manager will retain control of the budgeted contingency reserves for
individual contracts. These reserves will be budgeted for contract risks that have
been quantified and that are deemed highly likely to occur. Budgeting for risks will be
coordinated with the Program and Project Managers.
• Regularly integrate estimates for capital, support costs, and contingency reserves into a
program-wide report.
Caltrans Response:
The Project Manager will report quarterly on the status of the contingency reserve balance as
part of the updated risk response plan.
3. To ensure that it follows generally accepted management practices for communications
management, Caltrans should do the following:
• Submit quarterly status reports to the Legislature, as law requires.
Caltrans Response:
Caltrans agrees.
8866 California State Auditor Report 2004-140 California State Auditor Report 2004-140 8877
Sunne Wright McPeak
December 10, 2004
Page 8
• Ensure that reports to the FHWA and other stakeholders reflect current data and provide an
accurate representation of the program’s status.
Caltrans Response:
Caltrans agrees.
• When key events occur, such as a bid opening for a major project, quickly inform
stakeholders how these key events affect the overall program budget and schedule.
Caltrans Response:
The impact of these events on the budget and schedule will be reflected in the quarterly
updates of the risk response plan, project status reports, and the statutorily required reports.
In addition, updating will be reported to stakeholders immediately if warranted by significant
events.

COMMENTS
California State Auditor’s Comments
on the Response From the Business,
Transportation and Housing Agency
To provide clarity and perspective, we are commenting
on the response to our audit report from the Business,
Transportation and Housing Agency (agency). The
numbers below correspond with the numbers we have placed
in the margin of the agency’s response.
1
The concern raised in our report is not that the Department
of Transportation (Caltrans) did not report any expenditure
information but rather that Caltrans did not timely report an
accurate status of the Toll Bridge Seismic Retrofit Program’s
(program) financial condition, including realistic estimates of
future costs. As we note on page 52, the Caltrans director states
that Caltrans prepared no program-wide update of the program’s
cost estimates between April 2001 and August 2004. Further, as
we note on page 61 of the report, despite having to certify to the
Federal Highway Administration (FHWA) that the cost data in its
November 2003 financial plan update was accurate and provided
a realistic estimate of future costs, Caltrans did not perform
the work necessary to support this certification. As a result, we
found that significant differences existed between the cost data
Caltrans reported to FHWA in November 2003 and Caltrans’
internal records.
2
The definition of a cost overrun used in our report is the same
as that used by Caltrans in its report to FHWA. When Caltrans
provided detailed information to the federal government
supporting its November 2003 financial plan update, it noted
each instance in which a project’s estimated cost exceeded
budget as an “estimated cost overrun.” For example, it
characterized the signature span and Yerba Buena Island
component of the San Francisco-Oakland Bay Bridge’s east span
(East Span) as having a $312 million estimated cost overrun
even though a significant portion of this amount related to
contracts for which Caltrans had not yet received bids.
8888 California State Auditor Report 2004-140 California State Auditor Report 2004-140 8899
3
We did not make a determination whether Caltrans’ failure to
report on the program’s status was “an attempt to withhold
cost information.” However, as we note in the discussion
beginning on page 60 of the report, had Caltrans been
diligent in its responsibilities, it should have known as early as
November 2003 that the program was in financial trouble.
4
Caltrans contradicts itself in this paragraph. Caltrans asserts that
its briefings before the California Transportation Commission
(commission) “clearly laid out the status of the program,” which
implies that Caltrans was reporting not only the program’s
expenditures, but also a realistic estimate of the program’s future
costs. However, earlier in this paragraph Caltrans states that none
of its reports before May 26, 2004, indicated that Caltrans was
projected to spend more than the budget in Assembly Bill 1171.
As we note on page 61 of the report, despite having to certify to
FHWA that the cost data in its November 2003 report was accurate
and provided a realistic estimate of future costs, Caltrans did not
perform the work necessary to support this certification. As a result,
we found that significant differences existed between the cost data
Caltrans reported to FHWA in November 2003, when Caltrans said
project cost overruns would require $326 million of the program’s
$448 million contingency reserve, and Caltrans’ internal records.
5
Caltrans asserts that the bid opening for the signature
span’s superstructure, which represented $930 million of
the $3.2 billion funding shortfall, was the driving factor for
reporting cost overruns to the Legislature when in reality, other
significant factors should have driven it to report sooner. Table 3
on page 19 shows cost overruns for the program: $564 million
relates to the skyway; $1.348 billion relates to the signature span
(which includes the $930 million increased cost estimate for
the superstructure bid); $618 million relates to other East Span
projects; $249 million relates to the Richmond-San Rafael
Bridge; and $452 million relates to the need for additional
program contingency reserves. Interspersed among the cost
increases for specific projects is $556 million of additional
support costs that were needed because Caltrans extended the
program’s length by four years. While we recognize that the bid
for the superstructure was a significant event, it should not have
been the driving factor for reporting to the Legislature.
6
Caltrans says it had not conducted enough analysis until the
end of July 2004 to conclude that the East Span would be over
budget, however, there was sufficient information for it to have
9900 California State Auditor Report 2004-140 California State Auditor Report 2004-140 9911
conducted such an analysis in November 2003, if it had made
the effort to accurately report to FHWA. For example, as we note
on page 65, with the lengthened schedule for the East Span,
Caltrans would have only had enough funds to pay for about
one-and-a-half years of support costs at a time when it reported
to FHWA in November 2003 that the program’s schedule would
extend for another eight years. In addition, in November 2003
Caltrans reported that it had committed all but $122 million of
its program contingency reserve, despite the fact that it had not
yet received a bid for the signature span’s superstructure.
7
Caltrans intent to time its future updates of cost estimates for
projects under construction and for support costs with the
legally mandated quarterly report is a good first step, but is
inadequate given the program’s $8.3 billion cost and its high
risk. Based on its experience with the bid for the signature
span’s superstructure, annual updates of cost estimates for unbid
projects may not provide up to date and relevant information.
More frequent rather than less frequent updates of cost estimates
would allow Caltrans management to be alerted of problems
sooner and be able to implement corrective action as well
as notify stakeholders well in advance before cost overruns
soar out of control. As we note on page 52, FHWA strongly
recommends development of a monthly report with current
cost forecasts. Moreover, to meet its mandate under state law to
report to the Legislature when it determines that the program’s
actual costs exceed the budget, would necessitate more
frequent internal monitoring of the program’s expenditures
and estimated projected costs so that it can appropriately make
this determination. In contrast to Caltrans’ intended corrective
action, we note on page 70 that for programs under the Regional
Measure 1 Program, the commission receives monthly reports
from its oversight consultant on the cost and schedule status of
each project. These reports provide a mechanism to promptly
alert the commission to potential cost and schedule problems
with the program.
8
Caltrans appears to miss the intent of our recommendation.
We agree with Caltrans that it is important to reassess the
contingency reserve for individual projects, however, as noted
on pages 50 and 55, it is also important for Caltrans to reassess
the sufficiency of the contingency reserve for the entire
program based on risks identified and quantified through its
risk assessment process. In addition, it is important for Caltrans
to reassess contingency reserves for construction contracts that
9900 California State Auditor Report 2004-140 California State Auditor Report 2004-140 9911
have not yet been bid and to determine reserves for awarded
contracts where additional costs are quantifiable and probable,
not just where they are deemed highly likely to occur.
