Located on the Intracoastal Waterway in West Palm Beach, the LEED Silver certified, 25-story Bristol includes 69 condominiums with 165 below-grade parking spaces. The foundation system consists of 16” and 14” diameter auger cast piles. In the 2-level, below-grade parking garage, post-tensioned concrete slabs support double stacked cars, saving space and reducing the number of parking stalls and levels required.
The superstructure consists of cast-in-place concrete shearwall cores and post-tensioned concrete slabs. Architectural elements include an undulating floor-to-ceiling curved glass façade and broad, curved balconies that create a fluid design while providing shade to the units. To support the irregular cantilevered terraces, we used 10” thick post-tensioned concrete slabs. Beginning at the 20th floor and extending to the roof, the south side of the building recedes approximately 5 feet at each level. To support each setback, we used sloped perimeter columns, rather than transfer beams supporting intermediate columns. This allowed floor-to-floor heights to remain consistent, saving money and space. The sloped columns created horizontal thrust forces, which were distributed through the floor slabs and restrained by the shearwalls beyond.
