BEST TERRAZZO PROJECT

Transbay Salesforce Transit Center — Local 3 California

Signatory Contractor: Associated Terrazzo Co. Inc.

Artist Julie Chang’s design called for the transformation of the terminal’s 24,000 square foot Grand Hall floor into a stunning “secret garden.” The design is intricate and complex, demanding the master skills of BAC Local 3 California members to make it a reality.

Over ten years in the making, this project uses 16 colors and 375 waterjet-cut elements of brass and zinc to form the collection of hummingbirds, poppies, brass insects, and abstract shapes that make up the secret garden.

Unique requirements meant terrazzo was being installed on a concrete slab that contained a radiant floor heating system over several inches of rigid foam insulation.

In addition to the Grand Hall installation, 6,000 square-feet of single-color epoxy terrazzo flooring was installed in multiple sites in the building, including five staircases of precast terrazzo and eleven elevator cab floors.

The superior skill required to complete this magical terrazzo installation is a testament to the master craftmanship of the BAC Local 3 California members. Their talent ensures commuters will be dazzled by the beautiful design for years to come.
