Hopper dredging work is expected to commence in the fourth quarter of 2021 with estimated completion in the first quarter of 2022. The client on this project is the US Army Corps of Engineers, New York District and majority is federally funded with additional funding from the state of New Jersey. This project will provide beach fill to towns of Elberon and Sea Girt. Open options totaling $21.1 million remain in low bids pending award bringing total contract to $47.7 million. At this time the base contract was awarded that includes dredging from an offshore borrow area and pumping sand to Allenhurst and Deal beaches. The Sea Bright to Manasquan, Section II Beach Project that was awarded in the third quarter is part of the Sandy Hook to Barnegat Inlet Beach Erosion Control Project.

Numerous publications are available.HOUSTON, Oct. Army Corps of Engineers Waterways Experiment Station has a Dredging Research Program, a Dredging Operations Technical Support Program and a Dredging Operations and Environmental Research Program. The Great Lakes Commission has a web site for the Great Lakes Dredging Team a partnership of federal and state agencies to assure that dredging is done in a manner that meets environmental protection, restoration and enhancement goals. Other Web Sites with Dredging Information This saves not only valuable space in the CDF’s for only the contaminated material but also benefits the port and harbor region economically and environmentally by realizing dredged material can be a valuable resource and not just a waste material. Nowadays, port and harbor facility managers try to place only contaminated material into CDF’s while beneficially using the uncontaminated material for other types of projects such as construction projects, habitat creation or restoration, landfill and landfill cover material, soil amendments, and many other re-use applications. These structures are usually very large and very costly to construct. The removed material is then typically placed into a barge which transports the material to its final destination.ĭredged material is sometimes placed into specific engineering designed areas designed to contain the material called confined disposal facilities (CDF’s). Most common mechanical dredges used on Great Lakes projects are the grab or bucket type dredge. Mechanical dredges remove the sediments via mechanical methods which can include grab dredges (clamshells & buckets), backhoes or bucket ladder dredges. Sometimes a cutterhead is attached to the dredge intake to loosen hardened material. Hydraulic dredges use hydraulic pumps to produce a slurry of the dredged material, are typically used when there is much material to remove and it can be easily transported long distances via a pipeline attached to the dredge.
