The American Institute of Steel Construction’s group reviewing problematic built-up plate girders in San Francisco’s Salesforce Transit Center is considering the girders’ design detail—where the brittle fractures occurred. The team will also look into a similar girder failure at the SoNo Collection mall in Connecticut.
The American Institute of Steel Construction’s virtual steel conference—which replaced AISC’s annual gathering canceled due to the COVID-19 pandemic—offered dozens of no-cost online professional development hours to its 9,146 registrants.
The only group in the U.S. and Canada that collects and disseminates lessons from failures, errors, mishaps and safety issues is calling for reports on structural and jobsite hazards arising from the COVID-19 pandemic.
Corps Chicago District Commander Col. Aaron Reisinger and Walsh Construction Project Manger Tom Caplis detail how convention center will transform into an alternate care facility in days, including upgrade of Hall B mechanical system to produce negative air pressure for care of contagious patients.
As the Army Corps of Engineers planned and built alternate care facilities in Chicago's McCormick Place and Detroit's TCF Center, its public health strategy shifted to using convention centers for COVID-19 patients without severe symptoms rather than just for non-COVID-19 patients to take the strain off hospitals.
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.
