Construction Worker Dies at Denver Broncos Training Facility Site; OSHA Opens Investigation

A construction worker was found unresponsive in a confined ceiling space at the site of the Denver Broncos' new training facility on the evening of June 15, 2026. Despite rescue efforts by South Metro Fire Rescue crews who used tools to access the confined area, the worker was pronounced dead at the scene.

The incident occurred at approximately 8:20 p.m. at the construction site at 13409 E. Broncos Parkway in Arapahoe County. Co-workers discovered the man before emergency crews arrived.

The worker's identity had not been publicly released as of the date of this report, pending notification of family.

What investigators are doing

The Arapahoe County Coroner's Office is leading the investigation into the cause and manner of death. The U.S. Occupational Safety and Health Administration (OSHA) has opened a separate workplace safety investigation.

Turner Construction, the general contractor on the project, halted work at the site following the death. The Denver Broncos organization issued a statement acknowledging the incident and expressing condolences.

No findings have been released by OSHA. Under the agency's standard timeline, OSHA has six months from the date an inspection opens to issue citations in a fatality investigation.

The site

Construction on the new Broncos training facility began in August 2024. The $175 million project — Broncos Park Powered by CommonSpirit — is a 205,000-square-foot building roughly 30 percent larger than the team's current facility, which opened in 1990. The project was scheduled for completion ahead of the 2026 NFL season.

Confined space hazards in construction

Confined spaces — ceiling voids, crawl spaces, utility tunnels, and similar enclosed areas — are among the most dangerous work environments in construction. OSHA's confined-space standard requires employers to identify permit-required confined spaces before work begins, test the atmosphere for oxygen deficiency and hazardous gases, establish entry procedures, and maintain rescue capabilities on site.

Whether the ceiling space where the worker was found qualified as a permit-required confined space under OSHA's definition, and whether required entry procedures were followed, are among the questions the OSHA inspection will examine. OSHA fatality inspections frequently end in citations: in a recent trench collapse in Yarmouth, Massachusetts, the agency issued willful and repeat violations, and in a fatal Florida roofing fall it cited the employer for a willful failure to provide fall protection.
