Description
Award-winning Pelli Clark Pelli Architects designed the Salesforce Transit Center with “soaring light-filled spaces” to give “San Francisco a grand entrance that befits its status as one of the world’s great cities.” Inside the airy and spacious Grand Hall, sunshine is filtered more than 30 meter below the center’s above-street-level park by the CONTRAFLAM 120 and LITE-FLOOR walkable fire-rated glass floor and skylight. More than 4,000 sheets of glass make up almost 300 panels, providing daylight for the Grand Hall. A second installation brings natural light down below street level.
“When ground broke on this project, this technology didn’t exist,” says Kevin Norcross, General Manager, Vetrotech Saint-Gobain North America. “It has very specific specifications that have never been incorporated into a single project, ever. The fire rating, combined with the loading requirements and seismic resistance make it an engineering feat. It’s a testament to the innovation of our team.”
Pelli Clarke Pelli specified the most demanding requirements for a fire-rated glass floor and skylight to date for this project, and the solution is the only exterior multi-panel system to meet some of the world’s most stringent specifications and pass all tests, including two-hour fire rating and seismic-resistance, live loading for foot traffic and waterproofing.
