Part of a three-story parking garage under construction in central Lubbock collapsed at 9:54 a.m. Tuesday, injuring two workers.
Lubbock fire spokesman Chris Angerer says a beam was being installed when the piece of concrete fell from the top level of the garage at the Suites at Overton Park. That caused a serial "pancake" collapse of parts of the floors below.
Angerer says one of the injured workers was on the third level, but it wasn't clear where the other was. Both were taken to University Medical Center, but Angerer says their injuries don't appear to be life-threatening.
Lee Lewis Construction is building the garage for Lubbock-based McDougal Properties. Company president Mike McDougal says the concrete section that fell had been installed and inspected Monday.
Once again, the accident does not appear to have been caused by a structural failure, but by a large piece of concrete jarring or being dropped onto an existing concrete floor.
The U.S. Occupational Safety and Health Administration and Lubbock fire marshal are investigating.
Engineers are reviewing the damage and integrity of the remaining structure.
