Clark Construction Group, LLC was selected as the general contractor to build the new $275 million Headquarters for the U.S. Department of Transportation by the JBG/SEFC Venture, L.L.C. of Washington, D.C. Located on an 11-acre parcel within the Southeast Federal Center in Washington, D.C., the 1.9 million-square-foot complex consists of two towers, which will house the agency’s more than 5,000 employees. Two levels of below-grade parking also are planned.
Designed by Michael Graves Architects of Princeton, N.J., the complex spans two full city blocks, featuring a nine-story western tower and an eight-level eastern tower. This difference in height creates variety along M Street and emphasizes the western tower and its public entrance along New Jersey Avenue (a boulevard within view of the U.S. Capitol.) A multi-story lobby leads to adjacent first floor space, which will contain a large assembly area. A central linear atrium is planned in each of the buildings. While the towers are not physically connected across Third Street, the transparency of each tower’s atrium helps create a visual link between them.
Additional team members include DMJM H+N of Arlington, Va., executive architect and MEP engineer; Ai of Washington, D.C., tenant design architect; Weidlinger Associates, Inc. of Washington, D.C., structural engineer; URS Corporation of Gaithersburg, Md., civil engineer; Lee & Associates, Inc. of Washington, D.C., landscape architect; and Ducibella, Venter & Santore of North Haven, Conn., security consultant.
A tunnel for the Metro’s Green Line bisects the site, with the top of the tunnel approximately 17-feet below the lowest point of excavation. Construction of the lowest parking garage level will be performed around a 14’ x 14’ active sewer main. Construction is scheduled for completion in mid-2006.
