Building restoration of granite panels and aluminum window frames of the third tallest mixed-use tower in NYC

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 strategy developed by Henson 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.
