The National Transportation Safety Board has determined that the probable cause of the deadly March 15, 2018, Florida International University pedestrian bridge collapse was related to load and capacity calculation errors made by FIGG Bridge Engineers Inc.
The board also found that consulting engineer Louis Berger Group failed to catch FIGG’s design calculation errors that contributed to the collapse.
Louis Berger, the board said, did not detect the inadequate design of the main span truss member 11/12 nodal region and connection to the bridge deck, which was the area that exhibited significant cracking prior to the collapse.
