DOUBLETREE HOTEL 8 Stone Street
Located in the financial heart of downtown Manhattan, this 43-story hotel building has 424 guest rooms along with fine dining restaurants. The tight site and with two levels of underground spaces for the hotel back-of-the-house facilities posed structural challenges in developing an adequate foundation system. Working tandem with the geotechnical engineer, a foundation system using 400-ton reinforced concrete caissons were used to support the building structure. Concrete flat plate slab is used typically at the superstructure to achieve maximum number of floors within the zoning height limit while maintaining Hilton's standards for ceiling heights.
