The steel fabricator for the third-floor tapered, built-up plate girders at the troubled Salesforce Transit Center in San Francisco is calling for a girder-hanger connection design review as part of the probe into the causes of brittle fractures in bottom flanges of twin 80-ft-long members that bridge Fremont Street.
On Oct. 16, the Webcor/Obayashi Joint Venture, general contractor for the Salesforce Transit Center in San Francisco, filed a complaint San Francisco Superior Court against the hub's owner, the Transbay Joint Powers Authority, seeking more than $150 million in extra payments on its $994,517,600 contract.
The 58-story Millennium Tower in the Transbay district of San Francisco, which has sunk 18 in. and is tilting 2 in., is under even more scrutiny for possible structural defects since a window on the 36th floor cracked.
