Maintenance Dredging of Great Kills Harbor, Federal Navigation Project

Synopsis of Proposed Dredging - Maintenance Dredging of Great Kills Harbor, New York, Federal Navigation Project.

Background Information

The New York District of the U.S. Army Corps of Engineers (USAGE) proposes to perform maintenance dredging of Great Kills Harbor Federal Channel. The dredged material would be dredged and subsequently placed at the Historic Area Remediation Site (HARS), approximately 4 miles east of Sandy Hook, New Jersey.. The proposed maintenance dredging would remove approximately 200,000 cubic yards of dredged material from Great Kills Harbor. Dredging would be required to a depth of -10 feet and - 8 feet Mean Lower Low Water (MLLW) plus 2 feet allowable overdepth, respectively. The dredged material consists primarily of sand and gravel.

The purpose of the proposed work is to alleviate the effects of shoaling and restore the authorized project dimensions, thereby providing safe and economical use of Great Kills Harbor by military, commercial and recreational boating interests while providing future beneficial use of the dredged material.

Based on past dredging cycles, it is recommended that the proposed work only be performed by utilizing a mechanical dredge with a clamshell bucket. Additionally, multiple ocean-going barges, tug boats and ancillary equipment will be needed to perform the dredging, transport and placement activities. The entire channel will generally not require maintenance dredging; only areas where shoaling has reduced the depth of the channel will require dredging. The dredged material would be required to meet all federal, state, and local criteria required by the government agencies having jurisdiction where the placement site is located.

The Contractor will be required to commence work within five (5) calendar days after the date of receipt of the notice to proceed, and to prosecute said work diligently and to complete the basic work ready for use not later than seventy-five (75) 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.

The work is estimated to cost between $1,000,000 and $5,000,000. Plans and specifications for the subject project are expected to be available in April 2024, with bid opening in May 2024. It is the intention of the government to award in June 2024 and issue the NTP in October 2024.

Liquidated Damages of $3,046.00 per calendar day of delay will be assessed to the contractor until all work under the contract is accepted as complete.

This is an unrestricted Procurement.
