Major renovation and retrofit of the former Department of Transportation headquarters into a Class “A”, LEED Gold office building that exceeds GSA’s current Federal Office Building Standards and meets ISC Security Design Criteria. Access to the subway is provided through the L’Enfant Plaza station, at D Street, SW. The existing building was gutted down to its structure, which was salvaged and completely renovated to include replacement of the building façade and reconstruction of all service cores.
Amenity spaces were designed with a basic 30-ft. column grid to align with existing column spacing, with long-span designs considered for future tenant options. Enhanced physical security measures exceed ISC Level IV, and include progressive collapse mitigation and blast-resistant building envelope, anti-ram barriers along the building perimeter, blast-resistant loading facilities, and common security checkpoints.
The modernized building boasts sweeping views of the city, a fitness facility, 400-seat cafeteria, and a major conference center. The facility received Mid-Atlantic Construction’s 2010 Project of the Year Award in Renovation/Restoration.
