Federal investigators have determined that the tragic collapse of the Champlain Towers South in Surfside is likely to have originated from the pool deck. The National Institute of Standards and Technology (NIST) highlighted significant design flaws and critically low margins of safety in the pool deck structure as key factors contributing to the disaster. Signs of distress were reportedly observed weeks prior to the incident, emphasizing the need for thorough examinations in ongoing investigations. As the investigation nears completion, officials continue to assess the circumstances surrounding the collapse that resulted in numerous fatalities.
