The presentation will describe real-world case studies of concrete rehabilitation projects that experienced partial collapse events during active construction, and the steps taken by the forensic structural engineer during the subsequent urgent response.  Key takeaways from these case studies will suggest how to apply these hard-learned lessons to future repair strategies.
