Department of Transportation Headquarters



Weidlinger Associates provided structural design and blast engineering services for the Department of Transportation headquarters in Washington, DC. Located on an 11-acre parcel in the developing Southeast Federal Center, the 2-million-square-foot complex consists of a nine-story western tower and eight-story eastern tower, which houses more than 5,000 employees. Two levels of below-grade parking for 950 cars were also constructed. A multi-story lobby leads to adjacent first-floor space, which contains a large assembly area. Each building has a central linear atrium. Although the towers are not physically connected across Third Street, the transparency of their atriums creates a visual link between them.
