The American Institute of Steel Construction task group reviewed proposals made by California's Metropolitan Transportation Commission, in the aftermath of the 2018 discovery of brittle fractures in plate girders at the Salesforce Transit Center.

The public authority that owns and runs the Salesforce Transit Center in San Francisco forcefully disagrees with the Metropolitan Transportation Commission's independent expert panel that reviewed the 2018 brittle fractures in twin built-up plate girders.

The American Institute of Steel Construction has formed a task force to consider the recommendations made by the Metropolitan Transportation Commission peer review panel, on the fractured flanges in the Salesforce Transit Center, to determine if any changes need to be made to the AISC Steel Specification.

The independent panel reviewing the investigation of San Francisco’s troubled Salesforce Transit Center is tasked with both determining the cause of brittle fractures in two bottom flanges of twin built-up plate girders and assigning responsibility for the fractures, according to Ron Alameida, director of design and construction for the public owner, the Transbay Joint Powers Authority. 

Workers have completed repairs of the fractured girders at the beleaguered Salesforce Transit Center in San Francisco, shuttered since late September, some six weeks after it opened.

Field work to fix two fractured girders is underway at the troubled Salesforce Transit Center in San Francisco.

Cross-complaints filed regarding San Francisco’s troubled Salesforce Transit Center, shuttered after girder fractures

The steel subcontractor and the fabricator for the problem bridge-like spans at San Francisco's Salesforce Transit Center are vigorously countering the Transbay Joint Powers Authority's contention that a construction error caused the brittle fractures of the hub’s two built-up plate girders.
