Tishman served as Construction Manager for the restoration and reconstruction of Stephen Sondheim Theatre at One Bryant Park. The project aimed to create a state-of-the-art playhouse that captures the intimacy and proportions of the original 1918 Allen, lngalls & Hoffman Theater.
An elaborate three-story structural-steel support brace held the original landmarked façade in place during demolition of the existing theater and vibration monitors were used to ensure that it was not damaged. The foundation was excavated to a depth of 70 feet, the deepest foundation in midtown New York. As excavation took place, the existing façade was underpinned and openings were cut within it for new support columns. In the end, One Bryant Park and the new theater were erected adjacent to the freestanding façade, which was then connected to the new structure.
Stephen Sondheim Theatre is Broadway's first green theater, designed and built to LEED® Gold standards. Low-emitting, wood products certified by the Forest Stewardship Council and high-recycled content wall panels and baseboards were used extensively. About 25% of the materials were locally sourced.
