Salesforce Transit Center, San Francisco, CA

Within the Salesforce Transit Centre, the central transit hub of San Francisco, the space is open and light-filled. Tall, structurally expressive skylights — “Light Columns” — brings sunshine deep into the building, creating a vibrant and inviting atmosphere. The focal point of STC, and the solution to achieve it, is LITEFLAM XT 120 system; a walkable fire rated glass floor/skylight specifically developed for this project. This unitized multi-panel fire-rated glass floor system realized the Architects vision of " light columns" which flood the Grand Hall with natural light. The largest Light Column forms the central element of the 36-meter tall (118-feet tall) Grand Hall, STC’s primary public space. Reaching from the park, down through the bus deck and Grand Hall, and all the way to the train platforms two stories below grade, this dramatic structure will provide light and long views to all areas of the Transit Center. The specifications put forth by Pelli Clarke Pelli were the most demanding for a fire rated glass floor/ skylight to date. Some of these include: 2hrs fire rating, blast resistant, seismic rating, live loading for foot traffic and water proofing. It is the perfect expression of form and function.
