HST Roof Safety Construction Project

The General Services Administration (GSA) is conducting market research for a Sources‑Sought notice on the HST Roof Safety Construction Project at the Harry S. Truman Federal Building in Washington, DC. The effort is a repair‑and‑alteration (R&A) of the building’s roof system, requiring verification of existing conditions, fabrication and installation of anchorage, structural attachments, waterproofing, lightning protection, drainage, and related work, plus testing, labeling, as‑built drawings, warranties, and close‑out documentation. The contractor must perform a mandatory site visit, submit shop drawings and stamped calculations, coordinate security and access, and maintain existing roof warranties.
