Washington, DC
St. Elizabeths West Campus, Headquarters Building
Scope/Solutions
The redevelopment of St. Elizabeths west campus includes a new 1.3 million sq ft headquarters building and associated support facilities. Working with the Clark Construction/WDG Architecture design-build team, SGH consulted on the building enclosure design and construction for the array of interconnected buildings clad with a combination of stone, brick masonry, and curtain wall and covered with vegetative roofing.
SGH worked closely with the architect and contractor to establish and execute the building enclosure design.
Highlights of our work include the following:
- Establishing continuity of below-grade waterproofing across interconnected building segments with irregular footprints on a sloped building site
- Coordination of both above- and below-grade expansion joints
- Establishing water/air/thermal barrier continuity at roofing and curtain wall transitions
- Critical review of the cable-supported curtain wall at the main entrance to the facility
