State safety investigators and Minneapolis-based Mortenson Construction are seeking to determine the cause of a worker fatality on the $1.1-billion U.S. Bank Stadium project, which was being monitored via an enhanced safety program with the Minnesota Occupational Safety and Health Administration.
At about 7:45 a.m. on Aug. 26, Jeramie Gruber, 35, a worker with Berwald Roofing Co., and a co-worker fell from the edge of the stadium’s roof. According to Mortenson officials, Gruber died when he fell an estimated 30 ft onto an intermediate structure. The unidentified co-worker’s fall was arrested by a safety barrier and resulted in only minor injuries.
