CONCORD, Mass. – Maintenance dredging and rock removal at Portland Harbor in Portland, Maine, will be completed under the terms of a $9,231,250.00 contract recently awarded by the U.S. Army Corps of Engineers, New England District.
Work will be accomplished by Cashman Dredging and Marine Contracting, Co., LLC, of Quincy, Mass. Construction is scheduled to start on or about Nov. 1, 2013 and take 3 to 5 months to complete. The contract was awarded on Aug. 1, 2013.
“The work of this project consists of mechanically dredging the Portland Harbor 35-foot channel. About 700,000 cubic yards of sediment will be removed,” said Project Manager Jack Karalius, of the Corps’ New England District, Programs & Project Management Division in Concord, Mass.
In addition, there are five rock pinnacles protruding above the –35 foot mean lower low water (MLLW) plane, totaling about 1,500 cubic yards, which will be removed presumably by drilling or blasting.
Lobster relocation will be conducted by a non-Federal sponsor prior to dredging, requiring close coordination with all parties.
Dredge material disposal will be in open water at the Portland Disposal Site, approximately 10 miles away. The environmental work window when dredging can be performed is Nov. 1 to March 15.
The project will be managed by the Corps and all work will be accomplished under the supervision of a Corps’ Quality Assurance Representative to assure compliance with contract requirements.
