Terrazzo Contractor

Terrazzo Contractor Associated Terrazzo Company San Francisco, CA

Over ten years in the making, this terminal’s Grand Hall houses an exceptionally intricate public art installation in terrazzo. Sixteen colors and 375 waterjet-cut elements of brass and zinc form the “Secret Garden” design with its joyful collection of hummingbirds, poppies, brass insects, and abstract shapes. The design beautifully complements the scale and architectural elements of the space. The terrazzo was installed on a concrete topping slab that contains a radiant flooring system over several inches of rigid foam insulation. The design and installation of the floor also had to take into account a second phase of construction, in which large structural slabs will be removed for the installation of escalators to provide access to projected commuter and high-speed rail. Besides the Grand Hall installation, another 6,000 square-feet of single-color epoxy terrazzo flooring was installed in five different areas of the building at the same time, including five staircases of precast terrazzo and 11 elevator cab floors. When installers were asked to expedite the six-month installation schedule, they trimmed a month off and increased the quality of the bent divider strip patterns by pre-fabricating the divider strips on panels, many as large as 11×17 feet, aligned on the construction site.
