CONCORD, Mass. – Maintenance and repairs to the East Jetty feature of the Federal Navigation Project (FNP) in Green Harbor in Marshfield, Mass., will be completed under the terms of a $839,500.00 contract issued recently by the U.S. Army Corps of Engineers, New England District. Work will be accomplished by ACK Marine & General Contracting, LLC, of Quincy, Mass. Work is scheduled to start in late-July 2018 and take several months to complete. The contract was awarded on May 17, 2018.
Green Harbor in Marshfield is situated in the northwestern end of Cape Cod Bay, about 30 miles southeast of Boston and nine miles north of Plymouth Harbor.
“The work consists of repairing a 150-foot section of the east jetty at Green Harbor,” said Project Manager Bill Kavanaugh, of the Corps’ New England District, Programs/Project Management Division in Concord, Mass. The east jetty was damaged during winter storm Juno in 2015 and subsequent storms.
Approximately 1,200 tons of new armor stone will be required to make repairs to the landward section of the jetty. New armor stone will vary in size from 4-7 tons. Work includes excavating, removing, stockpiling, installing and reworking existing armor stone as well as acquiring and installing new armor stones in the jetty repair area. Repaired areas must be properly interlocked and be within specified design tolerances. Excavation and stone placement may be performed from land or water; however, new armor stones will need to be delivered via waterborne plant.
The Notice to Proceed was issued on May 25, 2018 and the contractor mobilized to the site on July 13, 2018. The first 300 tons of stone were delivered to the site on July 16, 2018 and physical construction of the jetty is anticipated to start the week of July 23, 2018. Completion is anticipated in late September 2018.
The project will be managed by the Corps under the supervision of a Corps’ Quality Assurance Representative to assure compliance with contract requirements. For details on the Green Harbor FNP visit: www.nae.usace.army.mil/Missions/CivilWorks/Navigation/Massachusetts/GreenHarbor.aspx.
