JOHNSTOWN, Colo. (CBS4) – Loveland Fire Rescue Authority says a construction worker died after a trench collapsed at a home construction site near Johnstown. The collapsed happened at around 3:45 p.m. on Friday.

Firefighters say three other men were trying to save the fourth worker who was under water. Firefighters ordered them out of the excavation hole for fear they, too, could be trapped.

The men were trying to connect a domestic sewer pipe to the public sewer main. They used a “sump-type device” to remove water from the hole. The trench then partially collapsed while water continued to flow into the hole.

“Early into the incident, responders transitioned to a recovery operation due to the continued collapse threat and constant ground water flow. The configuration of the excavated hole did not allow rescue shoring to be utilized to secure the walls of the hole. On site heavy equipment was utilized to enlarge the excavation site to allow rescuers to access the victim. The vacuum truck and small pumps were used to remove water from the work area as crews attempted to recover the victim,” Loveland fire officials said.
