The Nantasket Beach Hurricane and Storm Damage Reduction project in Hull, Mass., will be completed under the terms of a $2.7 million contract recently issued by the U.S. Army Corps of Engineers, New England District.
Work will be accomplished by George R. Cairns & Sons, Inc. of Windham, New Hampshire.
Construction is scheduled to start in January 2018 and extend over a 5-month period.
“The project consists of installing an approximately 2,200-linear-foot stone toe revetment along the seawall at Nantasket Beach Reservation on Hull Shore Drive in Hull,” said Project Manager Michael Riccio, of the Corps’ New England District, Planning Division in Concord, Mass.
The seawall was constructed in 1915 and has experienced failure due to undermining at the northern and southern bookend sections. Those sections have since been repaired and their footings fortified with stone revetments, leaving just the middle section project area unprotected.
According to the Corps, this project will fortify the middle section in order to create a single and complete revetment along the entire Nantasket Beach Seawall. The revetment work will include: shoreline excavation of approximately 27,000 cubic yards of existing beach material (expected to be re-used on site); placement of approximately 4,000 square yards of geotextile fabric; placement of approximately 1,600 cubic yards of gravel and crushed stone; placement of approximately 4,000 cubic yards of 350-pound stone; placement of approximately 10,000 cubic yards of 2-3 ton armor stone; placement of approximately 30, 6-foot by 3-foot by 2-foot granite slabs (access steps); and backfilling of the revetment with the excavated beach material.
Staging areas will be located on Nantasket Beach Reservation, which is owned by the Massachusetts Department of Conservation and Recreation, the project sponsor. The repair project will be managed by the Army Corps under the supervision of USACE’s’ Quality Assurance Representative to assure compliance with contract requirements.
