Champlain Towers South Investigation Team Provides Update to Structural Engineers

On Thursday, April 10, three members of the National Institute of Standards and Technology’s (NIST’s) National Construction Safety Team (NCST) investigating the June 2021 partial collapse of the Champlain Towers South building in Surfside, Florida, shared technical details of the investigation’s progress with members of the structural engineering professional community. This outreach will help ensure that the team’s findings and recommendations lead to improvements to codes, standards and practices that can prevent similar tragedies from occurring in the future.

Investigative lead Judith Mitrani-Reiser gave the technical presentation along with investigative co-lead Glenn Bell and Jim Harris, co-lead of the investigation’s Building and Code History Project. The presentation took place at Structures Congress 2025, an annual event of the Structural Engineering Institute of the American Society of Civil Engineers, held this year in Phoenix. While the three experts did not provide new findings, they did offer new technical details from the evidence analysis and testing that supported the preliminary findings NIST released in earlier public presentations.
