Planning, programming, design, and engineering services

This Federal Agency Headquarters in the heart of Washington DC serves over 8,000 full-time employees in a building of multiple-eras dating back to 1939. We partnered with the General Services Administration to plan and design a historically sensitive multi-phased modernization that significantly reduces energy use and improves the quality of the indoor environment, matched to the mission of the agency.

Our planning approach allows a significant increase in occupants in the building, allowing better collaboration to tackle critical issues facing the world, from climate change to human rights.
