Corps of Engineers Awards $4.9 Million Contract for Maintenance Dredging of Duxbury Harbor in Duxbury

Posted on October 19, 2015

Maintenance dredging of portions of the Federal navigation channel in Duxbury Harbor in Duxbury, Mass., will be completed under the terms of a $4,994,560.00 contract recently awarded by the U.S. Army Corps of Engineers, New England District. Work will be accomplished by Cashman/Burnham (C/B) Joint Venture of Quincy, Mass. Dredging is scheduled to start in October 2015 and take about 3 months to complete. The contract was awarded on Sept. 9, 2015.

Duxbury Harbor is located at the northwestern end of Cape Cod Bay in Duxbury, about 20 miles northwest of the Cape Cod Canal. It is an active recreational boating center. The Duxbury Harbor Federal navigation project consists of an 8-foot deep, 100-foot wide and 1-mile long entrance channel, and an 8-foot deep, 21-acre anchorage in the inner harbor.

“Work consists of maintenance dredging of approximately 200,000 cubic yards of predominantly silt-clay by mechanical dredge,” said Project Manager Bill Kavanaugh of the Corps of Engineers, New England District, Programs and Project Management Division in Concord, Mass.

A closed bucket will be used while dredging in the silty material to minimize turbidity adjacent to the dredge. The dredged sediment will be transported to, and placed at, the Cape Cod Bay Disposal Site located approximately 20 nautical miles from Duxbury Harbor. The environmental work window when dredging can be performed is Sept. 1 to Dec. 31, 2015.
