In the collapsed residential building in Surfside, Florida, USA, 90 people have been found dead so far, local officials said on Sunday, July 11.
The fate of 31 people is still unknown, and the search for rubble continues.
Built 40 years ago, the 12-story Champlain Towers South was partially destroyed on June 24. Dozens of people were rescued from the ruins, but no survivors were found after the day of the collapse.
The cause of the accident is still unclear, but the authorities have released a report issued by construction consultancy Morabito in 2018, which did not say the building could collapse, but acknowledged that it needed repairs to maintain “structural integrity”.
Inspectors have warned of significant problems found in the concrete block under the pool on the ground floor, as well as cracking of the concrete in the underground car park.
“If the waterproofing is not replaced in the near future, the degree of concrete damage will expand exponentially,” the report said. It assumes that the problems are largely due to the corrosive effects of Florida’s salty air over many years.
