Corps Awards Bearskin Neck Repair Contract

The Bearskin Neck Stone Jetty in Rockport, Mass., will be repaired under the terms of a $2.8 million contract issued recently by the U.S. Army Corps of Engineers, New England District.

Work will be accomplished by Classic Site Solutions, Inc., of Springfield, Mass. Construction is scheduled to start on or about October 15, 2014 and take about 6 months to complete. The contract was awarded on September 15, 2014.

The work on this project consists of repairing the 540-foot-long jetty that was damaged during Hurricane Sandy,” said Project Manager Stephen Dunbar, of the Corps’ New England District, Programs/Project Management Division, in Concord, Mass.

The Bearskin Neck Jetty is located at the northern end of Bearskin Neck Road in Rockport, approximately 35 miles north of Boston and 20 miles south of the New Hampshire-Massachusetts border. The jetty extends into the ocean from the end of Bearskin Neck Road to the east and provides protection to Rockport Harbor.

The existing jetty consists primarily of 3-5 ton armor stone. The ocean side of the jetty has retained its shape and authorized dimension while 400 feet of the jetty contains voids 5 feet deep along the crest profile and voids 5-10 feet deep along the harbor side slope. The head at the east end of the jetty is missing along with the U.S. Coast Guard Aid to Navigation that was mounted there.

Work tasks include: delivery and installation of approximately 4,000 tons of 14-19 ton armor stone and 6,000 tons of 4-8 ton armor stone to repair the jetty to authorized dimensions. Repairs will provide a crest width of 18 feet for the first 400 feet, widening for the next 70 feet to a fixed width of 28 feet for the last 30 feet, at the head of the breakwater.

Crest elevation is +18.8 feet mean lower low water (MLLW). Work includes replacing displaced armor stone to fill in existing gaps. A majority of the 18-19 ton stone will be used to reconstruct the last 30 feet, which is the head of the jetty. Repairs will require substantial moving and re-handling of existing stones to obtain the required interlocking placement.

The project will be managed by the Corps and work will be accomplished under the supervision of a Corps’ Quality Assurance Representative to assure compliance with contract requirements.
