Maintenance Dredging of Mattituck Harbor, New York, Federal Navigation Channel

Background Information

The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of the Mattituck Harbor, New York Federal Navigation Channel. The dredged material would be dredged and subsequently transported to and placed at an upland placement site at a contractor furnished, state permit upland placement site. The proposed maintenance dredging would remove approximately 11,500 cubic yards of selected critical shoals from the silty/clay areas in the Mattituck Harbor. Dredging would be required to a depth of -7 feet Mean Lower Low Water (MLLW) plus 1 feet of allowable overdepth. The dredged material is expected to consist primarily of silt/clay.

It is recommended that the proposed work only be performed by utilizing a mechanical dredge with a clamshell bucket. Additionally, multiple, ocean-going barges and tug boats will be needed to perform the work during the dredging, transport and unloading operations. The dredged material would be required to meet all federal, state, and approved local criteria required by the government agencies having jurisdiction where the dredging and placement sites are located.

The apparent low bidder shall, within 35 calendar days from the date the apparent low bidder is notified of being such, provide copies of all required permits and approvals for transportation, transfer, dewatering, processing and final placement of the dredged material for the upland placement portion of the project, and shall submit evidence of such permits and approvals to the government.

Once the contract is awarded, the contractor will be required to commence work within five (5) calendar days after the date of receipt of the notice to proceed and maintain an integrated production rate of at least 1,500 cubic yards per calendar day for the dredging, transportation, and final placement of the material. The presence of dredging equipment in the channel will impact ship traffic and it is necessary to maintain this production rate while minimizing the duration of this impact.
The proposed work is anticipated to take place between September and December 2024. The work is estimated to cost between $1,000,000.00 and $5,000,000.00.
