GSA, Robert N.C. Nix Federal Courthouse Post Office

HENRY ADAMS provided professional MEP design services for the renovation of the 50,000 SF historic Post Office space on the 1st Floor and mezzanine space within the Robert N.C. Nix Federal Courthouse Building.

Nix was constructed in 1937 and it has become a masonry office building located in the central business district of Philadelphia, PA. The 7-story Nix building is mixed-use which functions as a courthouse, an office, a post office, and houses around 16 tenants.

The mechanical scope includes HVAC and associated Controls. The electrical scope involves the lighting and controls. To prove compliance with applicable energy codes, the LEED documentation for lighting, lighting controls, and COMcheck calculations were submitted. The plumbing scope included sanitary, venting, water, and gas.

The space accommodates a federal agency with a staff of 120 while retaining the lobby space’s historic features and enhancing its public-facing services, and renovating the former post office work room and interior mezzanine with open-plan workstations; private offices; meeting rooms; training, break, and support rooms; and storage. The final construction cost was $16M and the project was designed to achieve LEED Silver certification
