Michigan firm to dredge lower Detroit River

Published April 12, 2012
DETROIT – The U.S. Army Corps of Engineers, Detroit District, awards a $1.1 million dredging contract for the Detroit River to Ryba Marine Construction Co., Cheboygan, Mich.

Beginning in early June, Ryba Marine will dredge 200,000 cubic yards of sand, silt and organic shoal material from the lower Detroit River near Lake Erie. The company will deposit the materials in the nearby Pointe Mouillee confined disposal facility located in Monroe County, Mich. Work is expected to wrap up by mid-July.
“We are pleased to provide this dredging for the Detroit River, which is a vital connecting channel within a Great Lakes Navigation System that provides an environmentally clean and economically efficient method of transporting commodities,” said Lt. Col. Mike Derosier, district engineer.

The job was contracted through a Multiple Award Task Order Contract, MATOC. A task order contract allows the Corps to compete required work among the selected contractors throughout the duration of the contract, while minimizing the delays of conducting a separate procurement for each requirement. This shortens the time needed for the advertise-bid-review-award process.

The U.S. Army Corps of Engineers, Detroit District, maintains a navigation system that includes 94 harbors and the Great Lakes Connecting Channels that join lakes Superior, Michigan, Huron, and Erie.
