WMATA Yard and Maintenance Shops Expansions
In response to increased ridership, the Washington Metropolitan Area Transit Authority (WMATA) added 200 train cars to its Metrorail system and increased parking capacity at its busiest stations. It also introduced eight-car trains at peak periods. This created infrastructure issues that needed to be addressed before the expanded fleet could be put into service, including Improvements at the authority's yard and maintenance shops to address storage and service and inspection needs.
WMATA pursued best value design-build contracting for procurement of its system-wide maintenance shop expansion work. As part of the Hensel Phelps design-build team, we assisted in the expansions of three facilities—New Carrollton Shop, Shady Grove Shop and Greenbelt Yard. We were the lead designer and design manager with overall responsibility for completing the designs on a fast track schedule.
An important design consideration was maintaining continuing operations within a fully functioning rail yard during construction. Early submittal of utility relocations and environmental permits also allowed construction to begin while production of final design continued. The design-build delivery method allowed for partnering cooperation of the owner, builder and designer to reduce costs and meet the expedited schedules.
