GSA U.S. Diplomacy Center Pavilion

Project Summary

Gilbane provided general contractor services for the new U.S. Diplomacy Center Pavilion.  The project comprised approximately 22,375 square feet adjacent to the State Department’s old War Department Building along 21st Street, NW, in Washington, DC. Work included a new entrance/exhibition and security pavilion within the existing building forecourt and involved historic building elements requiring an appropriate standard of care. The entrance pavilion includes a Lower Level accessible by elevator and grand stair, and a Main Level. The pavilion is constructed of steel on a concrete base with a glass curtain wall enclosure system.
