Almost a year after the tragic hangar collapse at Boise Airport, which claimed the lives of three men and left eight others injured, construction has resumed on the hangar.

Construction permits obtained by KTVB reveal that the company responsible at the time of the collapse is back at the site. Big D Builders is once again leading the construction of the hangar, according to public records.

The collapse occurred on January 31, 2024, when a privately owned hangar under construction at the Boise Airport collapsed. First responders worked overnight to assist the injured.

The victims, 59-year-old Craig Durrant, 24-year-old Mariano Coc Och, and 32-year-old Mario Sontay Tzi, all died from blunt force trauma, as reported by the Ada County Coroner’s Office. Durrant was one of Big D Builders' founders.

Following the collapse, the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) took over the site for investigation. After gathering sufficient evidence, OSHA returned control of the property to Big D Builders in April.

In June 2024, Big D Builders confirmed to KTVB that they would demolish the structure, which was torn down that same week.

In late July 2024, OSHA released its full report, which found that Big D Builders had neglected safety standards, noting signs of structural instability, including bent and curved I-beams, unbalanced columns, and snapped wire rope cables.

“Big D Builders’ blatant disregard for federal safety regulations cost three workers their lives and caused at least eight others to suffer painful injuries,” said OSHA Area Director David Kearns in July 2024. “The company’s irresponsible construction methods left the aircraft hangar’s structure extremely vulnerable.”

OSHA cited Big D Builders for one willful violation and three serious violations of federal safety regulations, with proposed penalties totaling $198,586.

Inland Crane, which was also working on the hangar site, received a citation from OSHA for one serious violation. The company was fined $10,163 for exposing workers to collapse risks due to a failure to ensure stability during the hangar’s construction.
