11 Hoyt Street
11 Hoyt Street is a 57-story, 620-foot-tall residential tower with 481 units, private outdoor spaces, a fitness and aquatic center, 75-foot-long pool, sauna, and yoga studio. To manage high building loads and a tall structure sensitive to differential settlement, Langan designed a mat foundation with drilled concrete settlement reducers into the sands beneath the tower. Since the site previously contained a below-grade parking garage, our team developed a solution to reuse the garage walls, which allowed the tower to be constructed from within and eliminated the need for a new cellar. We also completed test borings and test pits, provided special inspections, and coordinated agency approval for the excavations and foundations because of the site’s proximity to the subway.
