Constitution Center, D Street, SW

A major renovation and retrofit of the former Department of Transportation headquarters into a Class "A", LEED Gold office building that exceeds the GSA’s current Federal Office Building Standards and meets the 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 the replacement of the building facade and reconstruction of all service cores.

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.

ETI’s services on this project included: structural steel inspection; weld testing using ultrasonics for welds of the column steel jackets during construction; laboratory testing of concrete cylinders, mortar and grout tests, sprayed fireproofing testing and engineering supervision.
