TL;DR Summary

The National Institute of Standards and Technology (NIST) has released preliminary findings on the partial collapse of the Champlain Towers South building in Surfside, Florida, which killed 98 people in 2021. NIST's investigation is focusing on the failure of the building's pool deck, which was constructed improperly and didn't meet building codes. The team found problems in the way the concrete was cast, leaving it permeable to water and corroding much of its steel reinforcement. The NIST team's leading hypothesis is that the collapse began when the pool deck failed due to punching shear failure. The final report is expected in two years.
