MONROE — Badger State Ethanol was impacted twice Tuesday when the roof of a warehouse still under construction in the 11000 block of West 17th Street collapsed just after 2:30 p.m., injuring one worker, less than 12 hours after an early morning fire in one of the plant’s grain silos. 

According to building permits filed with the city, the structure was being built by B. Hagen Construction LLC, which is operated by Brian Hagen of South Wayne. Monroe Fire Chief Dan Smits said the plant plans to use the building as a warehouse for packaging operations once completed and was under ownership of the construction company at the time of the accident.

The man was taken by ambulance to Monroe Clinic ER around 2:45 p.m. after the incident. Smits said he believed the worker fell as the roof collapsed. 

Emergency personnel arrived at the scene to find the partially constructed building damaged. While the outer supports were still standing, wooden beams that had outlined roughly 50 percent of the building fell down to the interior portion of the building. The pitched trusses were folded down to the ground as the horizontal beams clung to the side fastenings. 

The man was taken away from the site by stretcher. Monroe Clinic spokesperson Patricia Lawson confirmed a patient had been admitted from the incident Tuesday and was in stable condition.

Smits said the Occupational Safety and Health Administration is investigating the cause of the incident.
