Agency: U.S. Army Corp of Engineers

Contract # W912WJ-14-C-0002

On November 19, 2013, Classic was awarded the Repairs to the South Jetty, Phase II in Newburyport Harbor, Newburyport, MA. This project was performed for the U.S. Army Corp of Engineers, New England District in conjunction with the Massachusetts Department of Conservation and Recreation, the Massachusetts Office of Coastal Zone Management and the Town of Newburyport, Massachusetts.

The work of this project consisted of repairing the Newburyport Harbor South Jetty by replacing displaced armor stones to fill in existing gaps in the jetty caused by Hurricane Sandy. The jetty extends out some 1400 feet into the Atlantic Ocean. For this project, construction operations were land based. Access to the work area was extremely limited. A 2,400 liner foot mat road was constructed across environmentally sensitive dunes to access the site. In addition, a time-of-year work restriction was enforced to protect the nesting habitat of the piping plover. All land-based work was required to be completed between September 1 and March 31. 

Classic developed a work plan that addressed all the requirements of the project and expedited the procurement of specialized equipment such as a large stone grapple that could be utilized with a 170,000 lb excavator capable of handling the 12 +/- ton armor stones. Upon specified testing and acceptance of new armor stone, Classic imported and placed approximately 10,600 tons of 6-12 ton and 1,770 tons of 1-3 ton armor stone between December 16 and April 15, 2014. Despite stringent regulations and formidable winter weather, the project was completed safely and ahead of schedule. As a result of the project, a 1400 linear foot, continuously armored jetty was left in place to assist in the battle against the constant beach erosion of Plum Island, MA.
