As a subconsultant to Parsons Transportation Group CSIE provided engineering services in support of the Dulles Corridor Metrorail Project – Phase 2: Package A design and construction administration activities. This project was the largest of three design-build packages that will complete Phase 2.
With Parsons as the lead designer, CSIE provided design support for Electrical, Traction Power, Communications, SCADA, Fire Alarm and Radio Engineering groups. CSIE’s responsibilities include engineering / design, calculations, quality control / reviews, drafting (Revit) and submittal reviews.
Location: Fairfax & Loudon Counties, VA
Size: 6 Metro Stations
Construction Cost: $1,200,000,000
Phase 2, Package A extends the Metrorail system from Wiehle Avenue in Fairfax County, VA an additional 11.4 miles northwest, through the Washington Dulles International Airport to a terminus near Route 772 in eastern Loudoun County. The engineering team is furnishing all necessary labor, materials and supervision to accomplish the final design of the Rail Line, Stations, and Systems elements for all of Phase 2, including:
- Rail tracks and supporting infrastructure at-grade in the Dulles International Airport Access Highway, Dulles Toll Road, and Dulles Greenway rights-of-way and elevated within the boundaries of Dulles Airport
- Rail Stations and supporting infrastructure in the median of the Dulles Access Highway or the Dulles Greenway at Reston Parkway, Herndon. Each median station will include pedestrian bridges crossing the DIAAH/DTR or the Dulles Greenway and entry pavilions, access roadways, surface parking and bus facilities
- Rail systems for all of Phase 2 including traction power sub stations, tie breaker stations, communications equipment, and train control equipment
