Experts Get 1st Clues On What May Have Caused Condo Collapse

Some of the concrete columns were cracked. The parking garage was frequently flooded with corrosive saltwater. And the roof was undergoing repairs, with crews pounding on the tower from above for weeks.

Officials don’t yet know whether any — or all — of those factors caused a Florida beachside condominium tower to suddenly collapse Thursday morning.

But experts are closely examining a 2018 report that identified numerous issues with the Champlain Towers South building in Surfside, including “major structural damage” to a concrete structural slab below its pool deck that needed to be extensively repaired.
