Added: Oct 01, 2015 3:24 pm

The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of Sandy Hook Channel, in the New York Harbor Federal Navigation Project, with subsequent placement of the dredged material at the Historic Area Remediation Site (HARS). The proposed maintenance dredging would remove approximately 220,755 Cubic yards of sediment to a depth of 35 feet below Mean Lower Low Water(MLLW) plus 2 ft allowable overdepth. The dredged material consists primarily of sand.

Based on past cycles of the proposed work in Sandy Hook Channel, it is recommended that the work be performed by large mechanical dredge. Additional multiple barges and tug boats may be needed to perform the work during dredging, transport and placement of the dredged material.

The Contractor will be required to commence work within five (5) calendar days after the date of receipt by him the notice to proceed. The contractor will be required to prosecute said work diligently and to complete the basic work ready for use not later than thirty-seven (37) calendar days after the receipt by him of the notice to proceed (NTP). The contractor is required to maintain an integrated production of at least 8,000 cubic yards per calendar day for the dredging and placement of the sand at the HARS.
