The second phase of the new Silver Line to Dulles Airport and Loudoun County is expected to cost $2.7 billion — slightly less than previous cost estimates for the project.
The Metropolitan Washington Airports Authority (MWAA) released the new figure Tuesday, as it prepares to issue a request for proposals on bids to build the second part of the 23-mile stretch of new Metrorail line.
The first phase of the project is under construction and will run from
Tysons Corner to Reston. It is expected to be finished in August 2013, but could be as much as $150 million over budget.
Construction of the second phase is expected to start in January, and take five years.
Last year, Transportation Secretary Ray LaHood personally helped negotiate a deal in getting the second phase started after debate arose over whether build an underground or above-ground station at Dulles International Airport. The MWAA board ultimately decided on an above-ground station.
Under LaHood’s memorandum of agreement with MWAA, the state of Virginia and Fairfax and Loudoun counties, the second phase of the project was expected to cost $2.8 billion, according to MWAA officials.
“The analysis released today is clear evidence that the collaborative approach to the Dulles rail project will result in significant savings for both taxpayers and toll users,”LaHood said Tuesday in an e-mailed statement. “Working together, MWAA, the Commonwealth of Virginia, and other stakeholders have shaved more than $1 billion from the project’s initial cost estimates. As we continue to make progress on a rail network that will dramatically relieve congestion and improve transportation options for the residents of Fairfax and Loudoun
Counties, I expect these joint efforts will lead to further benefits for the region.”
The new estimate is slightly lower because the design has been more developed, which allowed engineers to make better estimates, MWAA officials said.
The new, $2.7 billion cost assumes that Loudoun and Fairfax counties pay for construction of five parking garages and the Route 28 station. If the two counties don’t pay for that portion, the cost of the project would rise to $3.1 billion.
MWAA spent $47 million for a joint venture that included AECOM and Parsons Brinkenhoff to do the latest preliminary engineering and cost estimate. It hired another company — McDonough, Bolyard and Peck — to do another cost estimate. That firm estimated the second phase of the Silver Line would cost $3.3 billion.
Patrick A. Nowakowski, the executive director of the Dulles rail project, said the reason for the difference is the two firms used different assumptions for the impact of inflation.
Fairfax and Loudoun counties now have until June 4 to decide whether they will participate in the deal. Officials in Loudoun had expressed concern about the project’s cost.
Sharon Bulova, chairwoman of the Fairfax County Board of Supervisors, said Tuesday, “the figures look pretty much in line with what we’ve been anticipating.” She said Fairfax has advertised to try to find a developer to do a public/private partnership to develop their portion of the parking garages.
Bulova said public hearings would be held over the next month for the public to “weigh in and learn more” about the second phase of the Silver Line.
The second phase of the project has raised controversy among Virginia politicians who are worried about a project labor agreement and have pushed Gov. Bob McDonnell (R) to withhold the state’s $150 million contribution toward the project’s cost.
