He said it is impossible to tell from just the images whether the concrete used in original construction was weaker than the designs called for, or whether the apparent weakness was due to damage over time. He added that instead of seeing aggregate material mixed into the concrete, “it’s just homogenous,” which is likely indication of saltwater damage. “The white color just stuns me,” Aghayere told the newspaper. The National Institute of Standards and Technology (NIST) National Construction Safety Team (NCST) investigating the June 24, 2021, partial collapse of the Champlain Towers South building in Surfside, Florida, is preparing to begin invasive testing and preparation of physical evidence collected from the collapse site. Stone-like aggregates used to strengthen concrete during construction typically remain visible but they were not in the images from the collapse site. Raw video of Building Collapses in Miami - Champlain Towers South collapseAbout 55 of the 136 units at Champlain Towers South collapsed around 1:30 a.m., off. He said he was struck by how “powdery” and white the concrete in columns appeared in the newly released video. Joe Raedle/Getty Images In the pre-dawn hours of June 24, part of the Champlain Towers South condo building in Surfside, Fla., suddenly collapsed. While it’s already congested with rebar, at the splice regions, it would have been “even further congested,” Aghayere told the Herald. The risk posed by “congested” vertical rebar in columns would have been even worse in spots where the rebar overlapped, which is known as “lap splice” regions, Abieyuwa Aghayere, a Drexel University engineering researcher who also reviewed the video, told the newspaper. “There is no reason there should be that kind of bar congestion,” Lehman said. The images show beams, walls and columns that appear to be overcrowded with steel reinforcement, which suggests potential weaknesses, she explained. A federal investigation into what caused it has zeroed in on the building's pool deck. “If there’s that amount of corrosion, this should have been fixed,” she said. The partial collapse of the Champlain Towers South condominium in Surfside killed 98 people. ![]() She said that amount of corrosion should have been obvious and documented as part of the 40-year inspection that was ongoing when the building in Surfside, Florida, collapsed June 24. Nearly a week since the horrible collapse of the Champlain Towers South, a new video has emerged showing the building moments before it went down. In this webinar, WJE structural engineers Matthew Fadden and Gary Klein detail WJE’s investigation and findings, including our collapse theory.“The corrosion on the bottom of that column is astronomical,” Dawn Lehman, a professor of structural engineering at the University of Washington, told the Miami Herald. The video, which captures the southern side of the building. Credit: Miami-Dade Fire Rescue Department. Champlain Towers South building collapsed in Surfside, Florida. It shows the rubble that resulted from the collapse, and also clearly shows the standing portion of the building. Discover videos related to champlain tower original collapse footage on TikTok. Our investigation found that the flat plate slab supporting the pool deck above an underground garage was under-designed, with significant structural distress apparent before the collapse. 1361 Video annotated by The New York Times describes the stages of a deadly building collapse in Surfside, Fla., on Thursday. Surfside Champlain Towers South Condo Collapse & the Science of Concrete Video This image shows the aftermath of the Surfside condominium building collapse which occurred on June 24, 2021. Our scope of work included a review of design and construction records, videos, and photographs taken before, during, and after the collapse site inspections at the Champlain Towers South collapse site and NIST primary evidence facility testing of construction materials and subsurface conditions (in coordination with the involved parties) review of relevant codes and standards and structural analyses. ![]() The collapse of roughly half of the building occurred around 1:22 a.m. WJE was retained by attorneys representing the condominium association to determine the cause of the collapse and provide litigation support. The Dubai developer was the lone bidder for the property, paying 120 million last summer to buy it. Champlain Towers South opened in 1981 just north of Miami Beach and included 136 condominiums. Miami Herald Investigators with the National Institute of Standards and Technology issued a preliminary summary of their findings Thursday regarding the catastrophic collapse of Champlain Tower. In the early morning of June 24, 2021, the eastern half of the twelve-story Champlain Towers South Condominium collapsed, killing ninety-eight residents of the forty-year-old building in Surfside, Florida. ![]()
