New York City Hall

BBB has completed the first comprehensive rehabilitation of New York City Hall in more than 50 years, incorporating 21st century systems and technology into an iconic early 19th century landmark.

New York City Hall, completed in 1812, is one of the oldest government buildings in continuous use in the United States. Numerous renovations and modifications over the years compromised the historic integrity of the landmark building and affected the stability of the structure, necessitating an integrated rehabilitation approach. The NYC Department of Design and Construction engaged BBB to develop the preservation design principles needed to restore its significant interiors, repair chronic structural deficiencies, replace historic copper roofing, insert new mechanical and electrical systems, and integrate improvements appropriate to the historic context. The effort unifies a series of individual building projects into a comprehensive building upgrade program that includes life safety and sustainability upgrades such as PV solar arrays and a gas-generated fuel cell. The guiding objective was to integrate critical improvements in a very inconspicuous manner, preserving City Hall's historic fabric and spaces with as light a touch as possible.
