International Dredging Review

International Dredging Review

On September 12, the U.S. Army Corps of Engineers New England District awarded a $4,452,937.50 contract to H&L Contracting, LLC of Bay Shore, New York, for maintenance dredging of the Hampton Harbor Federal navigation project in Seabrook and Hampton, New Hampshire.

Dredging and disposal operations started on October 15 and are anticipated to take about 4 to 5 months to complete.

Approximately 150,000 cubic yards of sandy material are being hydraulically dredged from the 8-foot deep entrance channel, the 8-foot deep Hampton channel, the 8-foot deep cross channel, the 8-foot deep Hampton anchorage, the 6-foot deep Hampton anchorage, the 8-foot deep Seabrook channel, and the 8-foot deep Seabrook anchorage with the material pumped onto adjacent beaches in Hampton and Seabrook, according to Project Manager Coral Siligato, of the Corps’ New England District, Programs/Project Management Division in Concord, Massachusetts.

An optional bid item is included in the contract to hydraulically dredge approximately 2,500 cubic yards of sandy material from the state anchorage in Hampton with placement on Hampton State Beach.

Natural shoaling processes have reduced available depths to as little as 1 foot in the 8-foot MLLW channel in Seabrook and 8-foot MLLW anchorage in Hampton, as little as 2.5 feet in the 8-foot Seabrook Anchorage, and approximately 4.0 feet in the 8-foot MLLW cross channel, 6-foot MLLW Hampton Anchorage and 6-foot state of New Hampshire Anchorage making navigation hazardous or impossible at lower stages of the tide.
