Following 2021 Federal Highway Administration (FHWA) guidance on non-destructive testing (NDT) of fracture-critical members fabricated with Grade 100 steel, bridge inspectors need updated strategies to effectively assess and preserve these structures. TRB hosted a webinar on Thursday, July 24, 2025 from 12:00 PM to 1:30 PM Eastern with case studies demonstrating how non-destructive evaluation (NDE) results can inform bridge preservation decision-making. Presenters shared examples of applying NDE to evaluate Grade 100 steel during long-term structural monitoring. Attendees learned about project procurement, scoping, work progression, key findings, and lessons learned, including critical considerations and challenges encountered throughout the projects.
The slides are available.
