Almost three years before a Florida condominium tower collapsed, an engineer warned that the building’s pool deck failed to seal, causing “major structural damage,” according to records.
Champlain Towers South, the twelve-story residential tower in Surfside, Florida, partially collapsed in the middle of the night on Thursday. The death toll has risen to four and 159 are still missing.
Officials said at a news conference Saturday that fire and smoke from deep within the remains of the tower are slowing searches, the Associated Press said. While the rescue effort continues, the City of Surfside has released a number of documents about the building.
These filings include a 2018 field research report from Morabito Consultants that found the concrete structural slab under the building’s pool needed repair.
“If the waterproofing is not replaced in the near future, the extent of concrete deterioration will expand exponentially,” the report said.

The company recommended replacing the damaged plates. She also found “frequent cracks and flaking” in the concrete supports, beams and walls of the parking garage. The tower was built in 1981.
The report did not warn of impending danger and it is still unknown what caused the building to collapse. Surfside Mayor Charles Burkett told CNN that he had not seen the 2018 structural field survey report but said it was “not clear at the moment what exactly was going on in that building.” According to The New York Times, the report helped develop plans for a multi-million dollar repair project that was about to begin.
Burkett said during a news conference that he was working on a plan to relocate residents of Champlain Towers North, which was built that same year, the Associated Press reported. FEMA has agreed to pay for the accommodation. City officials are still collecting more information about the Champlain Towers East, which was built in a different style and likely built at a different time.
CNBC asked Morabito Consultants for a comment.
