CitySpire

Address: 150 West 56th Street, New York, New York
Year Built: 1987
Project Status: Complete

CitySpire, designed by Helmut Jahn, was the second tallest concrete tower in the world when it was built in 1987. As the tallest mixed-use tower in New York City, the LL11 repair program developed by SHA required careful planning and execution. The scope of work on this 75-story skyscraper included the repair of the curtain wall, stone panels, windows, and structural concrete.
