Maintenance Dredging of New York and New Jersey Harbor – Arthur Kill 50 foot Reach Federal Navigation Project
Market Survey Background Information
The New York District of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of the New York and New Jersey Harbor – Arthur Kill 50 foot Reach Federal Navigation Project to a depth of -50 feet Mean Lower Low Water (MLLW) plus 1 foot of allowable over-depth. The proposed maintenance dredging would remove approximately 100,000 cubic yards (CY) of material from the critical shoal area. The dredged material would be dredged and subsequently placed at a suitable, contractor provided, state permitted upland placement site(s). The dredged material is expected to consist primarily of silt and clay.
Based on the past dredging projects within the New York Harbor, and anticipated restrictions found in the New York State Department of Environmental Conservation Water Quality Certificate, the proposed work can only be performed by utilizing a mechanical clamshell dredge with environmental bucket. Additionally, tug-boats, sealed hull barges and survey vessels will be needed to perform the work during the dredging, transport, processing and placement activities. The dredging, transport and placement at a suitable, contractor provided, state permitted upland placement site(s) would be required to meet all federal, state, and local criteria required by the government agencies having jurisdiction where the dredging and placement sites are located. All necessary permits required for the dredged material placement will be provided by the contractor to the government.
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 dredged material, 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 2,500 cubic yards per calendar day for the dredging and placement of the dredged material. The presence of the 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 in the summer / fall of 2025. The work is estimated to cost between $10,000,000 and $25,000,000.
SURVEY OF THE DREDGING INDUSTRY
The following confidential survey questionnaire is designed to apprise USACE of prospective dredging contractors’ project execution capabilities. Please provide your response to the following questions. All questions are in regard to the Arthur Kill 50 foot Reach maintenance dredging project.
General
Equipment
13. What type of dredge equipment do you own and/or operate that is suitable for the work described? Do you own a mechanical dredge with a closed environmental clamshell bucket? Please list each piece of equipment capable of performing the work described, i.e. dredging, transfer, transportation, processing and final placement of the material. For each dredge that you list, please specify its bucket size(s), and any other salient characteristics.
14. Identify which dredge(s), including support equipment (tug, crew boat, scows, etc.), you would employ on this project. Also, for each dredge, identify the maximum dredging depth.
15. Do you own material scows? If so, how many do you have available for use? Please list the name of the scow, its type (ocean-going, sealed hull, etc) and the capacity.
16. Do you have the capability to process the dredged material on your own? If so please explain. If not, what commercial provider of dredge material processing will you engage for this project? What is the daily processing capacity in either case?
17. Will you be able to meet a production rate of 2,500 cubic yards per calendar day and complete all work?
18. Do you have experience with the use of an automated Dredged Material Monitoring System (Black Box / Silent Inspector) employing a Dredged Material Inspector (DMI)?
