Sara Nir, a resident, told The Post that shortly before 1 a.m., she noticed loud “knocking” noises that she assumed were caused by construction work.

“There’s got to be a very specific sequence of events that somehow evaded all the fail-safes in the code and everything else.” The building collapse is as shocking “to the public in general … as it is to the engineering community,” said Joe DiPompeo, the president of the Structural Engineering Institute of the American Society of Civil Engineers. Such a catastrophe is extraordinary for a 40-year-old building even if a range of imaginable failures had occurred, the experts said. In images of the rubble, four experts saw indications of “punching shear failure,” in which concrete slabs that make up the floors of a building detach from the structure’s vertical support columns. Of more than a dozen experts interviewed for this article, including nine structural engineers, most agreed that the collapse appeared to involve a failure at the lowest levels of the building or in the parking garage beneath it.

“And then once the middle of the building collapsed, number two, then the rest of the building didn’t know how to stand up and it fell down also, number three.” A resident told The Washington Post that part of the pool deck and the surface-level parking lot collapsed before the building. “There is a possibility that part of the pool came down first and then dragged the middle of the building with it, and that made that collapse,” said Kilsheimer, who had previously voiced skepticism about the significance of the damage noted in the engineer’s report. Kilsheimer, a veteran engineer hired by Surfside to investigate the collapse, told The Post that such a failure could have set off a wider catastrophe. Experts urged caution and some structural engineers said they doubted that a collapse in the deck slab would have jeopardized the beachside building’s overall integrity. The investigation into the collapse last Thursday is likely to take many months and may find no single definitive cause. At least 64 people were killed and 76 remain unaccounted for following a type of disaster that is unheard of in the United States.

The husband of another resident has said that his wife, who has not been seen since the disaster, made a similar observation in a telephone call shortly before the collapse.Īn engineer in 2018 found “major structural damage” in the pool deck area caused by what he said was a flaw that limited water drainage.

A Washington Post examination of video and images from the deadly collapse of a high-rise apartment building outside Miami - along with interviews with structural engineers, a key witness and an investigator - deepens questions about whether existing damage to a deck in the pool area contributed to the disaster.Ī resident told The Post that minutes before Champlain Towers South in Surfside came down, she noticed that a section of the pool deck and a street-level parking area had collapsed into the parking garage below.
