Schedule of Events:

Education Session #3: Florida Pedestrian Bridge Collapse Forensic Investigation
On March 15, 2018, the 175-foot-long post tensioned concrete FIU UniversityCity Prosperity pedestrian bridge collapsed over US Route 41 in southeastern Florida, resulting in six fatalities and injuring eight others. The bridge utilized a unique sculptural design incorporating a concrete truss and was constructed using the Florida International University’s Accelerated Bridge Construction technique. The structure was intended to be a signature landmark for the University. Mr. Nacheman and Mr. Pinto mobilized to the collapse site on March 18, 2018 on behalf of their client, one of the major insurance carriers directly involved with the design and construction team for the bridge. They were tasked with documenting the post-loss condition of the bridge, performing a detailed structural analysis to determine the cause and origin of the collapse, evidence collection, and developing conceptual repair/retrofit design options.

Education Session #4: FIU Pedestrian Bridge Collapse: Testing of Full-Size Replicas of Failed Connection
WJE was engaged by FIGG to carry out independent studies related to the collapse of the FIU pedestrian bridge. Among other studies, WJE developed and tested full-sized specimens to evaluate the significance of NTSB’s finding that the construction joint between the northernmost diagonal and deck was left in an as-placed condition rather than intentionally roughened as required by the project specifications. WJE’s tests demonstrated that had the construction joint been roughened as required by FDOT Standard Specifications, which were reconfirmed by e-mail prior to construction, the collapse would not have occurred. As such, WJE concluded that the collapse was due to a construction error rather than design.

Exhibitor Presentation #2:
BendTec, presented by Wendy Meierhoff-Aldrich

Education Session #5: Load Rating of Steel Substructure Units in Unconventional Steel Bridges
This presentation is about performing detailed level 1 load rating calculations of complex steel substructures for bridges in New York City. Previously, substructure ratings were not required as a part of the biennial inspection program but now, rating steel substructures are required. This presentation details the challenges we faced, and the overall procedure developed to perform the rating calculations.

Pearl #1: A CM/GC Approach for the Design of a Two-Girder Horizontally Curved Pedestrian Bridge
A CM/GC Approach for the Design of a Two-Girder Horizontally Curved Pedestrian Bridge
This presentation focuses on the unique design features and practical lessons learned for refined analysis of a unique two-girder pedestrian bridge. It will bring to light some of the benefits of the CM/CG process on complex bridge projects and its impact during the design phase. Discussion of a commonsense approach to investigating redundancy in pedestrian bridges will be presented.
Kenneth D. Price, PE, SE
