Greenland Wins Michigan Concrete Association Award of Excellence

Greenland Enterprises was recently recognized with a Michigan Award of Excellence by the Michigan Concrete Association. The award highlights the concrete work involved in Greenland’s boiler plant replacement project at the Soo Locks in Sault Ste. Marie, Michigan. Greenland is replacing the boiler system in the locks’ steam plant building with three natural-gas package boilers, and performing other significant improvements.

The boilers allow the locks to operate in cold weather, and the award recognizes “constructing a 55-foot-long concrete tunnel approximately 21 feet deep. The 8-foot by 8-foot tunnel was cast in place using a slide rail system as the shoring system.”

This project was particularly challenging because all materials and equipment for the project had to be transported to the job site between the Poe and Davis locks. Barge trip shad to be coordinated with the Lockmaster to schedule around freighter traffic at the busy locks.

“There were over 60 projects submitted for this year’s awards program, which made the selection very difficult,” said Corinna Ruthig, Financial Administrator for the association. The recognition is in the Structural – Navigation category.

“We appreciate the recognition from the Michigan Concrete Association, and we’re proud of the work the Greenland team accomplished with our partner Bacco Construction,” said Greenland President Steve Seckler. You can read more about the project award at
