The north jetty feature of the Hampton Harbor Federal navigation project in Hampton, New Hampshire, will be repaired under the terms of a $1.9 million contract issued recently by the U.S. Army Corps of Engineers, New England District.
Work will be accomplished by Mohawk Northeast, Inc., of Plantsville, Connecticut.
Construction is scheduled to start on or about September 15, 2016 and will take about 3-4 months to complete.
“The north jetty was damaged during Hurricane Sandy and subsequent storms,” said Project Manager Bill Kavanaugh, of the Corps’ New England District, Programs and Project Management Division in Concord, Mass. “Approximately 3,320 tons of armor stone will be required to make repairs to 4 identified work areas of the jetty.”
The work involves removing, replacing and reworking existing armor stone as well as placing new armor and core stone along the jetty. The repaired areas will be properly interlocked and be within specified design tolerances.
The stones will vary in size from 3-4 tons and 6-10 tons.
Due to shallow water depths adjacent to the landward end of the jetty, work at this end may be performed from land; the remainder of the work requires a marine based plant. Protection of piping plovers and their habitat limits construction from September 1 to March 31.
The contract was awarded on May 9, 2016.
