Restoring the Alexander Hamilton U.S. Custom House

SUPERSTRUCTURES is proud to have been selected by the United States General Services Administration (GSA) for restoration work on the Alexander Hamilton U.S. Custom House. The project is featured in a recent article by ENR New York.

A National Historic Landmark, the building houses offices of several Federal agencies and a branch of the Smithsonian’s National Museum of the American Indian. SUPERSTRUCTURES was chosen as engineers and architects for the $100 million restoration of the 1907 structure by Cass Gilbert.

The top-to-bottom restoration of the building’s envelope includes remediation of water infiltration in the basements and sidewalk vaults as well as restoration of masonry, windows, skylights, and the rotunda murals.

While ENR New York profiles this project as a showcase for a sustainable retrofit, we see it as an example of our maxim that “the greenest building is the one that already exists.” Embodied carbon efficiency is inherent to our “do no harm” restoration practice.

We’re grateful for this chance to preserve one of the most historic and iconic buildings in the city, just steps from our Wall Street office. It also attests to our strong track record of winning and executing complex projects for exacting agencies such as the GSA.
