A section of concrete on a parking deck under construction in Atlanta partially collapsed on Friday, injuring six workers.

Atlanta Fire Rescue Deputy Chief Glen Riley said firefighters cut out one worker trapped under debris with saws. Video from news outlets showed the worker, who Riley said had leg injuries, being strapped into a basket next to the collapsed section.

Firefighters then communicated with a crane operator using a construction worker’s radio, Riley said, as the worker was lowered to the street. The worker never lost consciousness, he added.

“That was an awesome job,” Riley said.

Other construction workers were injured but managed to walk away from the collapse, Riley told reporters at the scene.

Four workers were taken to hospitals, said Jason Wasulko, a spokesman for Batson-Cook Construction Co., which is building the structure. The six workers were employed by a subcontractor, Wasulko said.

“We are committed to the safety of every employee and trade partner working at our job sites,” Wasulko said in a statement.

A firefighter also was taken to a hospital, with likely heat exhaustion, Riley said.

The collapse involved part of a prefabricated parking deck under construction in Atlanta’s Midtown neighborhood, officials from Atlanta Fire Rescue said in a statement. A column on the 11th floor gave way, causing debris to fall onto the 10th floor. The cause for the collapse is unclear, Wasulko said, adding that engineers were inspecting the structural integrity of the rest of the parking deck. He said there had been no prior problems.

Riley voiced concerns that more of the structure could collapse and fall onto Interstate 75/85, a busy freeway through the heart of the city. Parts of adjoining streets and a ramp to the freeway were closed as a precaution.
