MWAA: Silver Line Phase 1 Final Costs Up $76 Million, Phase 2 to Take 13 Months Longer & Add to Costs

April 27, 2015   

Airports Authority Updates Status of Silver Line Metrorail Construction Project 

Design Changes Enhance Safety, Reliability, Environmental Protection

Will Add Time, Cost; Will Not Impact Dulles Toll Road Rates 

The Metropolitan Washington Airports Authority announced Monday that design modifications
made to enhance the safety and reliability of the Metrorail Silver Line, along with remaining
work to finalize Phase 1 of the overall project, will add $76 million, or about 2.6 percent, to the
previously announced Phase 1 cost. The new Phase 1 cost remains within the original federally
approved Phase 1 budget.

Toll rates on the Dulles Toll Road will not be affected. Toll rates will remain at current levels
through 2018, and the previously published, decades-long toll rate schedule will remain
unchanged.  Revenue from tolls is one of several sources of funding for the Silver Line project,
which the Airports Authority is constructing for the Washington Metropolitan Area Transit
Authority (WMATA).

A recently concluded global settlement with the construction contractor for Phase 1, Dulles
Transit Partners, along with the resolution of other outstanding matters – including the close-out
of Virginia permits which allowed Phase 1 work within Routes 7 and 123 in Tysons Corner, and
the execution of contracts to supplement certain Phase 1 work, as required by WMATA – has
allowed the Airports Authority to project a final Phase 1 close-out cost of $2.982 billion, which
represents an additional cost of about $76 million, and to move to the final close-out of the Phase
1 project.  The majority of the remaining work on Phase 1, which opened for business in July
2014, will be completed by the end of this year, including the delivery of 64 new rail cars at a
cost of $189.4 million to expand the Metrorail fleet.  Final close-out of Phase 1 is expected to
occur in 2016.

“The Phase 1 global settlement is an important milestone in the Silver Line project, following its
successful launch in July 2014,” Airports Authority CEO Jack Potter said.  “It gives us closure
on the most substantial cost component of Phase 1, ensures we will achieve the project’s federal
budget targets and allows us to maintain the existing toll schedule for the Dulles Toll Road.”

The ultimate impact of the Phase 1 additional costs may be reduced or even eliminated if the
contingency budget for Phase 2 of the Silver Line project is not fully used and the total project,
both Phases 1 and 2, comes in at or under the overall project budget.

The Airports Authority also announced an update to the construction schedule for Phase 2 of the
Silver Line project, which will extend service from the terminus of Phase 1 in Reston, Virginia,
through Washington Dulles International Airport and into Loudoun County, Virginia.
More than 150 modifications have been made and integrated into the design for Phase 2. Many
of these modifications parallel design changes made in the latter stages of Phase 1 and will
enhance the safety and reliability of Phase 2.  The modifications, when combined with associated
weather and construction delays, have extended the Phase 2 construction schedule by about 13
months.

“Over 100 design changes were made in Phase 1 – a large number of them ordered in the final
months of the construction process – requiring additional design, engineering, construction,
management and oversight work,” said Charles Stark, the Airports Authority’s executive director
of the Silver Line project. “For consistency, many of these same safety and reliability
modifications needed to be incorporated into Phase 2 of the project, which then impacted the
schedule.”

Potter said, “The added costs arising from Phase 2 design modifications will remain within the
Phase 2 contingency budget of $550 million and will have no effect on the toll rates on the
Dulles Toll Road. With our project partners, we are committed to limiting future design changes.
Phase 1 is already experiencing ridership beyond expectations, and significant construction and
development is underway along its path in the Dulles Corridor. We are confident that Phase 2
will experience similar success.” 
Construction of the Silver Line, one of the largest public transportation construction projects
underway in the country, is managed by the Metropolitan Washington Airports Authority, and is
being built in partnership with Loudoun and Fairfax counties and the Commonwealth of
Virginia, with financial assistance from the federal government.  It will be transferred to the
WMATA for operation upon completion.
