Minnesota firm wins $2.6 million contract for Duluth-Superior Harbor dredging, disposal site improvements

Published June 30, 2011
The U.S. Army Corps of Engineers, Detroit District, awarded a contract for site improvements at the Erie Pier Confined Disposal Facility, CDF, and dredging at Duluth-Superior Harbor in Duluth, Minn., and Superior, Wis.

Marine Tech of Duluth, Minn., was awarded $2.6 million to dredge 116,000 cubic yards of silt, sand and organic material from the western Lake Superior harbor, construct about 1,000 feet of berm, clean out a pond within the CDF, and install concrete Jersey barriers. The barriers will protect against dredged material falling back into the harbor at the offloading site where contractors move it from barges into the CDF.

“These site improvements will add years of capacity to the Erie Pier Confined Disposal Facility, and the harbor dredging will enable marine vessels to transport full loads of bulk commodities and cargo,” said Lt. Col. Mike Derosier, district engineer. “Coal, limestone, cement, and lumber are shipped in and out of this harbor, helping sustain the local economy and provide jobs.”

The dredging is expected to begin by early August and be completed in late September. The CDF improvements are expected to wrap up by late July of 2012.

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.

Points of contact for this project are Lynn Duerod, public affairs officer, 313-226-4680, or Mollie Mahoney, project manager, 313-226-2033.
