Video shows fatal building collapse at Argyle High School

Surveillance video of the April 2 collapse of an under-construction indoor activity center at Argyle High School shows metal posts and beams wobbling before they come crashing down, killing one worker.

The video shows two lifts working in the middle of the framework of the indoor activity center at 7:38 a.m. The west half of the framework began to tilt inward slightly before all the beams fell into a giant heap of twisted metal in a couple of seconds.

Construction worker Julio Perez Ledesma, 36, of Fort Worth, was working on one of the lifts and died when the beams crashed down on him. Three other workers were injured.

Five days later, on April 7, Daniel Moran, 22, of Haslet, was killed when he was run over by a truck while clearing out the wreckage from the building collapse.

Argyle’s school board conducted an emergency meeting that night, where trustees decided to hire a safety consultant to evaluate all of NorthStar Builders’ construction projects with the district. NorthStar representatives agreed to stop construction until the consultant submits a report to the district.

More than a week later, the district hasn’t chosen a consultant yet and there is no timeline for the audit.

The Occupational Safety and Health Administration is investigating both incidents at the Argyle school, about six miles south of Denton.
