Keville Enterprises Inc. provided construction management services in connection with Phase I & II of construction associated with the extension of the WMATA heavy rail system to Loudoun County including Dulles Airport. The Phase I $2.9 billion, 11.6-mile project connects to the existing WMATA system in East Falls Church and includes five new stations with an interim termination at Wiehle Ave.-Reston East station. The alignment of the new heavy rail transit system connects to the existing system at East Falls Church follows a viaduct to the Dulles Connector road where it stays on grade until rising to another viaduct crossing the Washington Beltway (I-495). It then follows Routes 7 and 123 in Fairfax, Virginia through a heavily congested environment via a 2400 foot tunnel section under Tysons Corner and emerging on a viaduct section along Route 7 to the Dulles Toll Road median where the guideway is at grade. The project also includes a major expansion of the rail yard at West Falls Church. KEVILLE personnel provide quality assurance services in connection with all aspects of the construction program including communication systems; track; power; automatic train control; civil, building and structures construction; fire protection; escalators and elevators. The project also required significant coordination with the Virginia Department of Transportation (VDOT) in Phase I where guideway construction was conducted in the median of Route 7; a major transportation artery in Northern Virginia. Maintenance of Traffic restrictions within the Route 7 Corridor allowing access to local businesses and commuters yet allowing for major infrastructure construction was a significant challenge that was achieved by the project team.
Phase II of the Silver Line a $2.7 billion, 11.2-mile extension to Phase I ties in to the existing system terminus at the Wiehle Ave.-Reston East station. Phase II includes six new stations including the Dulles Airport Station and terminates at the Ashburn (Route 772) Station. A major component is the construction of a new rail yard that will become home to the largest rail yard and maintenance facility in the WMATA system, with the ability to hold over 160 train cars. KEVILLE personnel provide Quality Assurance (Q/A) services in connection with all aspects of the construction program including utilities; roadways; communication systems; track; power; automatic train control; civil, building and structures construction; fire protection; escalators and elevators. In addition Keville personnel provided CPM scheduling, cost estimating services and document control services.
