Dear Sefi Engrs ,

Design error is the cause of this failure ,  and  doing PEER REVIEW ( PROOF CHECKING ) could have save  this Pedestrian Bridge collapse . This killed six people and injured about 10 people  :

The National Transportation Safety Board determined ( NTSB) , during a public board meeting held Tuesday, that load and capacity calculation errors made by FIGG Bridge Engineers, Inc., are the probable cause of the fatal, March 15, 2018, Florida International University pedestrian bridge collapse in Miami.
Contributing to the collapse was Louis Berger’s inadequate peer review, which failed to detect FIGG’s calculation errors in its design of the main span truss member 11/12 nodal region and connection to the bridge deck. The FIGG engineer of record’s failure to identify the significance of structural cracking observed in this node before the collapse, and failure to obtain an independent peer review of the remedial plan to address the cracking, further contributed to the collapse.

Six people died and 10 others were injured when the partially constructed FIU pedestrian bridge catastrophically failed, sending the 174-foot-long, 950-ton, bridge span onto SW 8th Street 18.5 feet below, crushing eight vehicles that were under the bridge. Six of the eight lanes of the roadway traveling under the bridge were open at the time of the collapse.
