GAO-06-528T: 

Mr. Chairman and Members of the Subcommittee: 

We are pleased to be here today to assist the Subcommittee in 
monitoring progress on the Capitol Visitor Center (CVC) project. Our 
remarks will focus on the Architect of the Capitol's progress in 
achieving selected project milestones and in managing the project's 
schedule since the Subcommittee's February 15, 2006, hearing on the 
project.[Footnote 1] As part of this discussion, we will address a 
number of key challenges and risks that continue to face the project, 
as well as actions AOC has taken or plans to take to address these 
risks. In addition, we will discuss the status of the project's costs 
and funding. 

Our remarks today are based on our review of schedules and financial 
reports for the CVC project and related records maintained by AOC and 
its construction management contractor, Gilbane Building Company; our 
observations on the progress of work at the CVC construction site; and 
our discussions with the CVC team (including AOC and its major CVC 
contractors), AOC's Chief Fire Marshal, and representatives from the 
U.S. Capitol Police. We also reviewed AOC's construction management 
contractor's periodic schedule assessments and daily reports on the 
progress of interior wall and floor stonework. 

In summary: 

Since the Subcommittee's February 15 CVC hearing, the CVC team has 
continued to move the project's construction forward, but we continue 
to believe, as we said at the February hearing, that AOC's proposed 
opening dates--April 2007 for the base CVC project and May 2007 for the 
House and Senate expansion spaces--do not allow enough time to complete 
several critical activities and to address problems, challenges, risks, 
and uncertainties. During the past month, the CVC team has essentially 
maintained the pace of critical interior wall stone installation, 
developed a draft work plan for floor stone installation, started to 
develop a work plan to prevent a stacking of trades[Footnote 2] during 
finish work, and maintained the opening dates that AOC announced at the 
February CVC hearing. However, the number of activities critical to the 
project's timely completion has increased, and several of these 
activities are now scheduled to take longer to complete than planned. 
In addition, wall stone deliveries are still backlogged, critical 
building systems still have to be commissioned and tested, and although 
the project's overall design is essentially complete, certain design 
elements are still incomplete or are being clarified or refined. If the 
CVC team is successful in addressing these issues, we believe that the 
base CVC project can be opened to the public with a temporary cap on 
visitor occupancy in May 2007 and that the expansion spaces can be 
opened for occupancy beginning in mid-August to early September 2007. 
Congress may even be able to occupy the expansion spaces earlier if AOC 
implements a phased opening plan it is considering and if AOC is able 
to perform acceptance testing of the CVC and the expansion spaces 
concurrently rather than sequentially--a possibility AOC is continuing 
to explore. Nonetheless, we believe that AOC will be challenged to meet 
the later dates we are projecting because of the problems, challenges, 
risks, and uncertainties facing the project. 

We currently estimate that the total cost to complete the entire CVC 
project is about $556 million without an allowance for risks and 
uncertainties. This estimate exceeds our February 15 estimate by about 
$1 million because AOC now preliminarily estimates that it will need 
about that much to pay for contractual support needed to complete 
acceptance testing of the facility's fire protection system in time to 
meet the project's schedule. AOC plans to use its general 
administration appropriations for this work, including funds for fiscal 
year 2006 that it has on hand and about $950,000 in fiscal year 2007 
funds that Congress has not yet provided. To date, about $528 million 
has been provided for CVC construction. We continue to estimate that 
AOC will need about $25.6 million more in CVC construction funds to 
complete the entire CVC project without an allowance for risks and 
uncertainties and taking into account funding AOC plans to use from 
existing appropriations. Our $584 million estimate of the cost to 
complete the entire project with an allowance for risks and 
uncertainties remains unchanged because the cost of acceptance testing 
is one of the uncertainties covered by this allowance. 

AOC Has Moved Construction Forward, but the Project Continues to 
Experience Delays and Face Risks and Uncertainties: 

AOC's February 2006 schedule shows, as did its January 2006 schedule, 
that the CVC base project will be ready to open to the public with a 
temporary certificate of occupancy on February 13, 2007, and that the 
House and Senate expansion spaces will be ready for occupancy on April 
24, 2007. To allow for possible delays and start-up time for 
operations, AOC has proposed an April 2007 opening date for the base 
project and a May 2007 occupancy date for the expansion spaces. AOC 
expects all construction work in the CVC, East Front, and expansion 
spaces to be completed by the April opening date for the base project, 
but the CVC's occupancy at any one time will be temporarily limited to 
3,500, compared with about 4,200, the normal anticipated occupancy 
level.[Footnote 3] 

Our Analysis Indicates Later Opening Dates Than AOC Is Proposing: 

We continue to believe, as we testified in February, that the CVC is 
more likely to be ready for opening with a temporary certificate of 
occupancy by about the end of May 2007 than by April 2007, as AOC is 
proposing. Our projected opening is somewhat later than AOC's because 
CVC team managers and members we interviewed believe that certain work, 
such as interior stonework and finish work for the base project and 
East Front, will take longer to complete than the revised schedule 
allows. Our projection also assumes that AOC will be successful in 
addressing the challenges it faces and takes into account the time that 
AOC believes will be necessary to prepare for operations after 
construction work is completed. Similarly, we continue to believe that 
the House and Senate expansion spaces are more likely to be ready in 
mid-August or early September 2007 than in April or May 2007, as AOC is 
proposing. We consider the later time frames more likely for two 
reasons. First, AOC has scheduled the acceptance testing of the 
expansion spaces after the acceptance testing of the base project and, 
according to our analysis, the base project's testing will take longer 
than scheduled. Second, AOC's Chief Fire Marshal believes the 
acceptance testing of the expansion spaces will take longer than 
scheduled. However, the expansion spaces could be ready sooner if AOC 
advances the schedule for the acceptance testing--a possibility AOC is 
exploring. 

Although construction work has been progressing and the sequence 2 
contractor has met several schedule milestones, delays have continued 
in a number of areas, and ongoing risks and uncertainties could cause 
further delays. AOC's construction management contractor reported that, 
in terms of the dollar value of the work in place, the overall CVC 
project was about 77 percent complete and the sequence 2 work was about 
63 percent complete as of February 28-up from about 74 percent and 59 
percent, respectively, as of January 31. Furthermore, as of March 13, 
the sequence 2 contractor had completed work on five of the nine 
schedule milestones that were due to be completed by today's hearing, 
according to the project's January 2006 schedule. Three of the five 
were completed on time or ahead of schedule. (See table 1 in app. I.) 
According to AOC's construction management contractor, during the last 
4 weeks, the sequence 2 contractor installed 4,363 pieces of interior 
wall stone, compared with its 4,794-piece wall stone installation 
target, but installed only 1,590 square feet of its preliminary 3,600 
square-foot floor stone installation target. (See table 2 in app. I.) 
In addition, in measuring the sequence 2 contractor's February 
performance against the project's January 2006 schedule, AOC's 
construction management contractor reported delays in 12 of the 20 
activity paths identified as important to meeting the base project's 
overall completion date. These delays included, but were not limited 
to, work in the East Front, the exhibit gallery, the auditorium, the 
utility tunnel, the great hall, and the orientation theaters and ranged 
from 2 to 36 work days, but did not affect the base project's overall 
completion date.[Footnote 4] According to the CVC team, the delays 
occurred for a variety of reasons, such as design changes, problematic 
sequence 1 work, late submissions or approvals of shop drawings, and 
changes in the sequence of work activities by the sequence 2 
contractor. Finally, in its CVC progress report for February, AOC's 
construction management contractor said that the sequence 2 
contractor's monthly billings (reflecting the value of construction 
work done relative to the project's schedule) were generally not 
sufficient to meet AOC's currently scheduled completion date. 

The construction management contractor's February progress report also 
showed that several House and Senate expansion space activities had 
fallen behind the project's January 2006 schedule. These activities 
involved work on the House and Senate circular stairs, the House and 
Senate lower levels, and space intended for use by the U.S. Capitol 
Police on the service level. The CVC team said these activities were 
delayed because of (1) problems associated with sequence 1 or other 
sequence 2 work, (2) redesign resulting from the CVC team's 
misunderstanding of congressional requirements for certain space, or 
(3) security-related design changes. According to the CVC team, these 
delays will not affect the schedule for opening the expansion spaces, 
but could delay the base CVC project's opening if the lost time cannot 
be recovered, since certain expansion space work must be completed 
before the CVC can be opened to the public. At this time, the sequence 
2 subcontractor doing the expansion space work believes that most, if 
not all, of the lost time can be recovered and that all expansion space 
construction work necessary for the CVC's opening will be completed by 
December 31, 2006. 

Project's Schedule Remains Vulnerable to Problems, Challenges, Risks, 
and Uncertainties, Despite Actions AOC Has Taken and Plans to Take: 

As we indicated during the Subcommittee's February 15 CVC hearing, we 
believe that AOC will be challenged to meet even the later opening 
dates we have identified, given the problems, challenges, risks, and 
uncertainties facing the project. A brief update on these, as well as 
on AOC's actions and plans for addressing them, follows: 

* Delivery of stone and pace of stone installation remain critical. In 
the 4 weeks preceding today's hearing, the sequence 2 contractor 
reported receiving 9 of the 10 truckloads of interior wall stone it was 
expecting from the stone fabricator, but had not received any of the 20-
truckload backlog. According to AOC, the supply of interior wall stone 
is adequate for the CVC at this time, given the quantity on hand, 
providing that the fabricator continues to deliver about 1,000 pieces a 
week for the next 12 weeks. However, AOC said that the pace of 
installation is such that additional delays are likely to occur if the 
fabricator does not deliver the needed stone on time. According to 
AOC's construction management contractor, the sequence 2 contractor has 
installed 4,363 pieces of interior wall stone since the last hearing, 
meeting about 91 percent of its production target. By contrast, the 
sequence 2 contractor has installed only about 1,590 square feet of 
floor stone, or about 44 percent of the quantity specified in a 
preliminary floor stone installation plan that the contractor provided 
to AOC shortly after the February 15 hearing. In addition, seven of the 
nine schedule milestones that AOC and we have been tracking for the 
Subcommittee for today's hearing are related to interior wall stone 
installation, and the sequence 2 contractor has met three of these 
seven milestones. Although the sequence 2 contractor has recently 
increased the number of stone masons working on the project, delays are 
likely if the targets for interior wall and floor stone installation 
are not achieved. The targets could possibly be missed if the masons 
are less productive than planned, work spaces are not ready or 
available for stonework to begin, or the fabricator fails to deliver 
stone on time. During the February 15 hearing, we noted that it was 
critically important for the CVC team to aggressively address this 
area. AOC and its construction management contractor agreed and have 
been tracking interior wall stone installation daily. In its February 
CVC progress report, AOC's construction management contractor noted 
that interior wall stone delivery was the most critical issue at that 
time. 

* Trade stacking could delay completion. As we discussed during the 
Subcommittee's February 15 CVC hearing, trade stacking could hold up 
finish work, such as drywall or ceiling installation, electrical and 
plumbing work, plastering, or floor stone installation. This work could 
be stacked if wall stone is not installed on schedule. Although the 
pace of wall stone installation was essentially maintained in February, 
it is not, according to AOC's construction management contractor, 
sufficient to eliminate the risk of trade stacking and delays in finish 
work. Such a situation could also increase the risk of accidents and 
injuries. Hence, it remains important, as we said at the February CVC 
hearing, for the CVC team to closely monitor construction to identify 
potential trade stacking and promptly take steps to avoid or, if 
necessary, address it. The CVC team has also identified trade stacking 
as a high risk, and the sequence 2 contractor has begun to develop area-
by-area plans that will show when each subcontractor will be working in 
each area. The sequence 2 contractor expects to complete these plans 
over the next few weeks and to meet regularly with its subcontractors 
to review and update the plans. We believe this is a positive step but 
note that further delays in completing wall stone installation could 
still limit the available work space, making it difficult for all the 
trades to complete their work on schedule. AOC agrees and plans to 
monitor this situation during its weekly risk management meetings with 
the CVC team. 

* Complex building systems remain a significant risk. The CVC will 
house complex building systems, including systems for heating, air 
conditioning, and ventilation; fire protection; and security. These 
systems not only have to perform well individually, but their operation 
also has to be integrated. If the CVC team encounters any significant 
problems with their functioning, either individually or together, 
during commissioning or acceptance testing, the project could be 
seriously delayed. The shop drawings for the CVC's fire protection 
system, which are expected by the end of this week, have not yet been 
approved by AOC's Chief Fire Marshal. Delays could arise if the 
proposed system does not meet the design specifications or fire 
protection code requirements. In addition, the Chief Fire Marshal notes 
that delays could arise if the CVC team does not adequately pretest the 
system and correct any problems found during the pretesting. The CVC 
team is aware of these risks and has been taking steps to mitigate them 
as part of its risk management process. During the Subcommittee's 
February 15 CVC hearing, we suggested that the CVC team reassess its 
risk mitigation plans to ensure that it has identified the steps 
necessary to prevent major problems during the building systems' 
commissioning or testing and has measures in place to deal quickly with 
any such problems should they arise. AOC agreed and said that the CVC 
team will be continuously assessing this situation as part of its risk 
management process. It is also important to note that the Chief Fire 
Marshal's timely completion of the fire protection system's acceptance 
testing depends on his ability to obtain sufficient funding for a 
contractor to help his staff perform the tests. We will discuss this 
funding issue later in our testimony. 

* Building design continues to evolve. The CVC has undergone a number 
of design changes. Some of these changes, such as changes in the 
exhibit gallery and in the East Front, have resulted in delays. In 
addition, designs or shop drawings for some elements of the project, 
such as certain security features, space for the Capitol guide service, 
and aspects of the facility's fire protection systems, have not yet 
been completed or fully approved and are subject to change. Moreover, 
eight design changes or clarifications have been issued since January 
25, 2006. Additional design changes are being considered and have the 
potential to cause further delays. During the Subcommittee's February 
15 CVC hearing, we said it would be important for the CVC team to 
carefully consider the need for proposed scope and design changes and 
try to minimize the impact of necessary changes on the project's 
schedule and cost. AOC agreed and said it plans to make only necessary 
design changes. 

* Multiple critical activity paths complicate schedule management. In 
reporting on the project's February 2006 schedule, AOC's construction 
management contractor identified 20 critical activity paths that are 
important to the project's on-time completion--2 more paths than the 
contractor identified in reporting on the project's January 2006 
schedule. According to the contractor's report on the project's 
February 2006 schedule, several of these activities fell behind 
schedule during the month and could delay the project's completion if 
the lost time cannot be recovered. As we have said in a number of our 
previous testimonies on the CVC, having a large number of critical and 
near-critical activities complicates project management and increases 
the risk of missing completion dates. We believe that the CVC team will 
be particularly challenged to manage all of these areas concurrently 
and to deal effectively with problems that could arise within these 
areas, especially if multiple problems arise at the same time. During 
our February 15 testimony, we said that it would be important for the 
CVC team to reassess its capacity to effectively manage and coordinate 
the schedule and work for the remainder of the project. According to 
AOC, the CVC team has done this and believes that it has the needed 
capacity. While we believe that the steps being taken by the sequence 2 
contractor to address trade stacking should, if effectively 
implemented, help in managing these critical activities, we continue to 
be concerned about this issue and plan to monitor it closely as the 
project proceeds. 

* Opening the CVC and expansion spaces at different times is likely to 
result in a temporary cap on CVC occupancy and increase costs. As we 
reported during the Subcommittee's February 15 CVC hearing, AOC's 
current plan to open the CVC in April 2007 before the expansion spaces 
are scheduled for completion is likely to result in a temporary cap on 
visitor occupancy and a need to construct temporary emergency exits for 
fire and life safety protection.[Footnote 5] AOC is proposing this 
sequential approach because it believes that conducting the acceptance 
testing for the fire protection system for the CVC and the expansion 
spaces concurrently would delay opening the CVC to the public. Although 
AOC has not yet estimated the additional costs associated with the 
temporary measures that would need to be taken, it does not believe 
they will be substantial. During our February 15 testimony, we said 
that it would be important for AOC to identify and consider the pros 
and cons (including the estimated costs) of opening the CVC and 
expansion spaces at about the same time and provide this information to 
Congress. AOC agreed and said that a senior superintendent with its 
construction management contractor will be evaluating this situation 
and that AOC will provide the information to Congress when the 
evaluation is complete. 

Finally, as we have said in previous discussions with AOC, its 
construction management contractor, and the Subcommittee, it will be 
important for AOC to have adequate analysis and documentation of the 
reasons and responsibilities for delays.[Footnote 6] We discussed this 
issue with AOC and its construction management contractor again last 
week, and they agreed to reassess this area and get back to us after 
the reassessment is done. They said that although they had received 
requests related to accelerating sequence 2 work, they had not yet 
received any requests from contractors for payment of costs related to 
delays encountered during sequence 2. However, they consider such 
requests likely in the future and agree that they need good information 
for evaluating them. 

Need for Additional Funding Has Grown: 

In February, we estimated that the total cost to complete the entire 
CVC project would be about $555 million without an allowance for risks 
and uncertainties and could be as much as about $584 million with such 
an allowance. To date, about $528 million has been provided for CVC 
construction. This amount does not include about $7.7 million that was 
made available for either CVC construction or operations.[Footnote 7] 
According to AOC, it expects to use about $2 million of this amount for 
construction. To obtain the additional funding that it expected to need 
to complete the project's construction, AOC, in December 2005, 
requested $20.6 million as part of its budget request for fiscal year 
2007. This request was based, in part, on discussions with us and took 
into account our November 16, 2005, estimate of the cost to complete 
the project's construction without an allowance for risks and 
uncertainties and funding from existing appropriations. Our subsequent 
work--completed in preparation for the Subcommittee's February 15 CVC 
hearing--indicated that AOC would need about $5 million more, or about 
$25.6 million in additional funds, to complete construction without an 
allowance for risks and uncertainties. AOC has indicated that it plans 
to request this additional $5 million as a supplement to its fiscal 
year 2007 budget for CVC construction. 

In February 2006, AOC contracted with a fire protection engineering 
firm, in part, to help AOC's Fire Marshal Division inspect, test, and 
review plans for the CVC's fire protection system. AOC has not yet 
received the final shop drawings for this system, but it preliminarily 
estimates that these contractual support services will cost about 
$1,150,000. According to AOC, it may be able to reduce these expected 
costs and it will be exploring ways to do so. On the basis of AOC's 
preliminary estimate and belief that the expected costs may be reduced, 
we added $1 million to our $555 million estimate of the cost to 
complete the entire project without an allowance for risks and 
uncertainties, bringing our total estimate to $556 million. We did not, 
however, change our $584 million estimate of the cost to complete the 
entire project with an allowance for risks and uncertainties, since 
contractual support costs for acceptance testing would be covered under 
such an allowance. Nor did we change our $25.6 million estimate of the 
additional CVC construction funds AOC would need because AOC has used 
and plans to use a different appropriation account to pay for this 
contractual support. AOC has used and plans to use its general 
administration account because this contractual support is needed to 
accommodate an overall increase in the Fire Marshal Division's 
workload, including its CVC-related work. AOC plans to use a total of 
$200,000 in fiscal year 2006 general administration appropriations to 
pay for contractual support for the CVC's acceptance testing and has 
requested another $450,000 in fiscal year 2007 general administration 
appropriations. After AOC has received the final shop drawings for the 
CVC's fire protection system and has explored ways to reduce the cost 
of needed contractor support, it plans to reprioritize its fiscal year 
2007 general administration budget request to obtain the remainder of 
the funding needed. At this time, AOC expects this amount to be 
somewhat less than $500,000, which would bring the total fiscal year 
2007 funding needed for contractual support for CVC acceptance testing 
to about $950,000. We plan to monitor and report to the Subcommittee on 
these costs as soon as AOC has a firmer estimate. 

Mr. Chairman, this completes our prepared statement. We would be 
pleased to answer any questions that you or Members of the Subcommittee 
may have.

FOOTNOTES 

[1] GAO, Capitol Visitor Center: Results of Risk-based Analysis of 
Schedule and Cost, GA0-06-440T (Washington, D.C.: Feb. 15, 2006). 

[2] Trade stacking can occur when workers from different trades, such 
as stone masons, electricians, plumbers, or plasterers, have to work in 
the same area at the same time to meet a schedule, sometimes making it 
difficult to ensure sufficient space and resources for concurrent work. 

[3] This temporary limit will be necessary because the "horizontal 
exits," or passages, through the expansion spaces, which the life 
safety code requires for exiting the base CVC project, will not be 
available until later. These horizontal exits cannot be used until the 
fire alarm system in the expansion spaces has been fully tested and 
accepted--work that is not slated to be completed until after the base 
CVC is scheduled to open. Some additional work will likely be required 
to provide temporary emergency exit routes from the CVC, but the CVC 
team does not believe that this work or its costs should be 
substantial. 

[4] However, several activities, including interior wall stone 
installation, penthouse mechanical work, and East Front fire protection 
system acceptance testing, were delayed to the extent that even 
relatively short additional delays could affect the CVC's overall 
completion date. 

[5] According to AOC, the CVC's occupancy at any one time would be 
temporarily limited to 3,500, compared with about 4,200, the normal 
anticipated occupancy level, until acceptance testing of the fire 
protection system for the expansion spaces has been completed.

Management and Updated Cost Information Are Important, GAO-05-811T 
(Washington, D.C.: June 14, 2005). 

[7] Public Law 108-447, enacted on December 8, 2004, provided that up 
to $10.6 million could be transferred from AOC's Capitol Building 
appropriation account for the use of the CVC project. The use of the 
amount transferred is subject to the approval of the House and Senate 
Committees on Appropriations. In June 2005, AOC received approval to 
use about $2.8 million of this $10.6 million, leaving a balance of 
about $7.7 million that can be used in the future after a rescission 
amounting to $84,800. AOC recently received approval to use more of 
these funds; we will discuss this in our testimony for the next CVC 
hearing.
