A lawsuit has been filed by victims injured when an HVAC system fell into a pool at Gaylord Rockies Resort in Aurora in May 2023. Aurora Fire Rescue said six people were injured when a large portion of steel ductwork collapsed onto the pool below that had 50 to 100 people in it on May 6. Two of the victims were taken to the hospital with life-threatening injuries. The lawsuit is against Gaylord Rockies Resort as well as 11 other defendants. 9NEWS legal expert Whitney Traylor went over the lawsuit and said with that many defendants, there will be a lot of finger-pointing if it goes to trial. "Clearly there was some negligence because something like this doesn't happen without negligence," Traylor said. "The real question is, who is at fault and what proportion?" The lawsuit claims that at the time of the collapse, the ductwork improperly contained a significant amount of water, showed a significant amount of rust corrosion on the internal surface and that the cable suspension system was grossly insufficient to support the weight of the ductwork. "Due to failures in the design, construction, material selection, maintenance, and monitoring of the HVAC system in the Pool Building, numerous components of the HVAC system, including hangers, cables, and clamps, corroded to such an extent that their structural integrity was compromised less," the lawsuit says.
