Crews have started the work to shore up a part of the Salesforce Transit Center that crosses over San Francisco's Fremont Street.
The process to fix the two cracked steel beams that were discovered in the transit center earlier last could take several days, but crews have not announced when the part of Fremont Street and the whole center will be reopened.
“We are currently installing the pad on Fremont Street. Once that’s completed, we’ll be able to put the jacking system on top of the pads and start installation of the shoring system," Mark Zabaneh, the executive director of Transbay Transit Center, said Monday.
The transit center opened just one month ago and serves in part as a regional bus depot. Buses are now operating from the Temporary Transbay Terminal at Howard and Main streets in San Francisco where they operated from before the transit center opened.
Officials with the joint powers authority said a shoring design was completed Saturday and is being reviewed by an independent organization. Materials arrived Saturday and began Sunday.
A peer review will be done of the permanent repair plan and on the entire building following a request for both by the authority's board chair Mohammed Nuru, who is also the director of public works for San Francisco.
Authority officials said a peer review was done as part of the original design process.
The officials have not said what exactly caused the cracks, but speculated they may be related to the beams' fabrication, installation or the center's design.
A web portal was launched Saturday where the public and news reporters can access the peer reviews, design reports, contracts and inspections.
Some documents have been posted and more will be added on an ongoing basis.
Officials with the authority continue to work with contractor Webcor/Obayashi and structural engineers Thornton Tomasetti to address the problems and install a shoring system while a permanent solution is created.
Fremont Street and the transit center will be closed at least through next week.
