Project Overview

• Seven-story, National Historic Landmark
• One of the first projects completed under the Inflation Reduction Act
• Recipient of the Roger Corbetta Award for Repair and Restoration award

The Alexander Hamilton U.S. Customs House is a seven-story Beaux-Arts National Historic Landmark in Manhattan, NY. It features steel framing, stone façade, and Corinthian colonnades. Constructed in 1907, the historic building remains in active use, housing federal offices.

Following significant water damage from Hurricane Sandy, the building’s structural steel, masonry, basement, and sidewalk vault infrastructure required extensive repairs. A comprehensive restoration addressed structural deterioration and water infiltration while preserving the architectural character of this historic landmark.

PULLMAN restored the building envelope, waterproofed critical areas, and repaired and replaced structural steel to improve long-term durability. As one of the first projects completed under the Inflation Reduction Act’s low-carbon concrete requirements, low-embodied-carbon (LEC) materials, including concrete, steel, and concrete masonry units (CMU) were used, supporting federal sustainability objectives under the Inflation Reduction Act.

Restoring an occupied, high-traffic historic building presented several challenges, including restricted access, congested mechanical systems in the subcellar, and unforeseen conditions requiring additional shoring and repairs. The project team divided the work into three phases to minimize disruption to building tenants and visitors.

Through close collaboration and coordination, PULLMAN and the project team addressed these conditions while advancing critical waterproofing, structural steel, and building envelope restoration work.

The restoration addressed water infiltration and structural deterioration while extending the service life of the Alexander Hamilton U.S. Customs House and supporting its continued use. The project received the Roger Corbetta Award for Repair and Restoration from the Concrete Industry Board (ACI New York Chapter), recognizing the quality of the historic restoration work.
