NIST Update on Investigation Into the Collapse of Champlain Towers South
SEPTEMBER 7, 2023
On June 24, 2021, Champlain Towers South, a 12-floor condominium in Surfside, Florida, partially collapsed at approximately 1:30 a.m. EDT. The collapse happened suddenly and has resulted in mass casualties.
On June 25, NIST began deploying a team of six scientists and engineers to collect firsthand information on the collapse. Since then, NIST experts have been working with federal, state and local authorities to identify and preserve materials and information that might be helpful in understanding why the collapse occurred.
Preliminary evaluations show additional deviations from design in pool deck construction, no underground voids.
Specifically, the team found that the number of slab reinforcing bars centered over vertical columns was inadequate and that the reinforcing bars in the top of the slab in the vicinity of the columns were spaced farther apart than the design required. These deviations weakened the slab-column connections.
