OKC United States Post Office and Courthouse building

The United States Post Office and Courthouse building, located in downtown Oklahoma City, is a Beaux Arts limestone building constructed in 1912, with the central Art Deco tower added in the 1930s. Directly adjacent to the north is the Moderne-style Federal Building and Courthouse constructed in the 1960s. Starting in 2013, Walter P Moore was part of a multi-disciplinary project team engaged by the General Services Administration (GSA) to conduct a study into the potential seismic and blast resistance of the two buildings. Although portions of the federal building complex had been retrofitted previously for security purposes, the GSA is planning to address critical vulnerabilities in the remaining facility systems, including structural and fenestrations.

Walter P Moore performed a detailed assessment of the existing conditions, particularly addressing building enclosure and structural concerns. Detailed analysis was also performed of existing systems and compiled into a seismic and security retrofit feasibility study. The findings from the feasibility study will be incorporated into future design-build construction projects.
