The US Post Office and Courthouse in Brooklyn.

US Post Office and Courthouse – Brooklyn



Protective Design, which became a Thornton Tomasetti practice in September 2015, provided blast analysis and hardening engineering for a historic post office building that was undergoing a modernization and upgrade to house both U.S. post office and courthouse facilities.

Rising to the Design Challenge
The conversion to add a U.S. Bankruptcy Court and Attorney’s Office to an existing post office facility presented unique structural engineering and protective design challenges. The post office required public access and an active loading dock for truck drive-through at the ground level, while the US Attorney’s Office required secured entrances, parking, and shuttle service to the federal courthouse across the street.

The multifunctional, budget-conscious program combined hazard reduction and landmark appearance requirements. To meet these challenges, our engineers designed separating walls and hardened existing slabs to isolate the courthouse from the postal area. We developed an interior blast curtain for the wood-framed windows to limit potential hazards in courthouse areas.
