San Francisco, CA – The Transbay Joint Powers Authority (TJPA) announced today that crews continued their work throughout the night to assess and test steel beams and prepare the site for a shoring installation at the Salesforce Transit Center. Crews removed ceiling panels and moved light fixtures and utilities and are relocating some of Muni’s Overhead Contact System that services electric buses so that shoring can begin.
Crews found no additional fissures.
The two beams identified with fissures remain localized to the area above Fremont Street at the Salesforce Transit Center. There is a photo of the second-discovered fissure below.
The shoring system is currently being designed to address the issues around Fremont Street, and materials are being acquired. Work to install the system could begin as early as this weekend.
The agency also announced a media hotline for reporters to get updated, recorded information. The number is (415) 597-4039.
As previously announced, on Tuesday, September 25, 2018, crews discovered a fissure in a steel beam in the ceiling of the third-level Bus Deck on the eastern side of the Salesforce Transit Center near Fremont Street, which prompted closure of the building. This triggered additional inspections, revealing a second fissure, again at the Fremont Street location. The closure was conducted as a safety measure out of an abundance of caution after conferring with design engineers and contractors.
The TJPA continues to work with Webcor/Obayashi and structural engineers Thornton Tomasetti to address these issues and repair and install a shoring system. All transit operators are temporarily providing bus service out of the nearby Temporary Transbay Terminal at Howard and Main streets until the shoring system is installed.
“We are working expeditiously to address these repairs so that we can reopen Fremont Street and the transit center, but our work will be thorough and rigorous,” said Mark Zabaneh, Executive Director of the Transbay Joint Powers Authority. “Safety remains our top priority.” For transit information, riders can call 511 or go to 511.org or contact their bus operator, who are in contact with the TJPA about these impacts.
The TJPA will update the media again tomorrow.
