It’s not just about checklists, inspections, and meetings, said Steve Skau, vice president of safety and compliance for Nelosca Technologies. It’s also about everyone on a job having the ability to give feedback and know it will be valued.

“Everything we do at Nelosca starts with safety, no matter what scope of work we’re doing,” Skau said. 

80 years old and 35 years since its last rehab, LaGrange Lock and Dam in Versailles, IL was in major need of rehabilitation. Nelosca partnered with prime contractor Shimmick Construction (Shimmick) and the U.S. Army Corps of Engineers (USACE) Rock Island District, along with hundreds of crew members, to execute quality repairs through the existing lock.
