US Supreme Court House


The Supreme Court Building was designed by Cass Gilbert and built from 1931 to 1935.  The Court first sat in the building on Monday, October 7, 1935.  The building, majestic in size and rich in ornamentation, serves as both homes to the Court and the manifest symbol of its importance as a coequal, independent branch of government. Architectural information describing many of the building’s sculptural elements may be obtained from the Visitor Desk on the ground floor.


The project involved the removal of the existing built-up roof system down to the structural concrete deck and installation of a new hot fluid-applied rubberized roof system in an IRMA configuration together with precast concrete pavers, copper flashings, and copings. Additionally, hazardous material abatement was required once other contractors failed to perform.

Due to the building’s importance, its congested location, its occupancy, and its multiple levels, this project consisted of few logistical challenges to be accomplished. Limited crane access required multiple mobilizations and crane types, the largest being 500 tons. In order to load material and access performance of work, staging platforms and bridges were constructed. Pedestrian protection and signage were provided and operated to safeguard employees and visitors. The project was completed two days ahead of a stringent schedule and within the owner’s budget.
