Summary

Story summary

Investigators found that the Champlain Towers South collapse likely originated in the pool deck, not the tower.
Cracks and leaks were evident weeks before the June 2021 disaster, which resulted in 98 fatalities.
NIST utilized simulations and physical evidence to substantiate their conclusions.
Design flaws and inadequate reinforcement led to dangerously low safety margins in the pool deck's slab-column connections.
A public update on the ongoing investigation is anticipated in spring 2026, with a new luxury condominium planned for completion by 2029.
