Hudson River FNC Maintenance Dredging

Maintenance Dredging of Hudson River Federal Navigation Project – Haverstraw Bay, New York

Market Survey Background Information

The New York District (NAN) of the U.S. Army Corps of Engineers (USACE) proposes to perform maintenance dredging of the Hudson River Federal Navigation Project.  The dredged material will be transported and placed at a government provided Historic Area Remediation Site (HARS), located at the New York Bight Apex in the Atlantic Ocean.  The proposed maintenance dredging will remove approximately 200,000 cubic yards of critical shoals from the Haverstraw Bay dredging area.  Dredging will be required to a depth of -32 feet Mean Lower Low Water (MLLW) plus 1-foot allowable over depth.  The dredged material is expected to consist primarily of silt and clay.

Due to the conditions found in the water quality certificate, the proposed work may be performed by utilizing a mechanical dredge with a closed clamshell environmental bucket.  Additionally, multiple barges and tugboats will be needed to perform the work during the dredging and unloading/placement operations.  All necessary permits required for the dredging and dredged material placement will be provided by the Government.  The Contractor will be required to meet all conditions pertaining to dredging and dredge material placement as specified in these permits.

Water Quality restrictions preclude performing any in-water dredging work outside of the window provided in the contract.  To successfully complete the dredging of the required material within the contract’s in-water work window, the Contractor must be prepared to maintain a minimum average daily dredging production rate of 2,610 cubic yards of pay material.  Maintaining an acceptable production rate will be critical to the successful completion of the contract work and will minimize the duration of impacts to ship traffic using the Hudson River Federal Navigation Channel.

The proposed work is anticipated to take place between   August and November 2026, with all the in-water dredging work commencing no earlier than 15 August 2026. The work is currently estimated to cost in the range of $10,000,000 to $25,000,000.

SURVEY OF THE DREDGING INDUSTRY

General

1. Have you ever worked on dredging jobs similar in nature to this project?  If so, please describe the project and for whom the work was performed.  Identify a point of contact and phone number, if possible.

2. What percentage of work (volume of material dredged, transported, dewatered, processed, and ultimately placed) can you perform with your own equipment or equipment owned by another small dredging contractor?

3. Have you performed dredging within the Hudson River Federal Navigation Channel, or similar areas within the Hudson River Estuary? 

4. Are you experienced with HARS placement / ocean dumping of dredge materials?

5. Would you be bidding on this project as a sole contractor, prime contractor with subcontractor(s) or as a joint venture?

6. Is there a dollar limit on the size of contract that you would bid?

7. What is the largest dredging contract, in dollars, on which you were the prime contractor?

8. What is your bonding capacity per contract?  What is your total bonding capacity?

Equipment

1. What type of dredge equipment do you own and / or operate that is suitable for the work described?  Do you own a closed environmental clamshell bucket?  Please list each piece of equipment capable of performing each type of work described, i.e. dredging, transportation and final disposal of the material.  For each dredge that you list, please specify its bucket size(s), and any other salient characteristics.

2. Identify which dredge(s), including support equipment (tug, scows, etc.), you would employ on this project.  Also, for each dredge, identify the digging depth.

3. How many material scows do you have available for use?  Please list the name of the scow, its type, and the capacity.

4. Please list any history with the dredging and placement of HARS and non-HARS material.  Also list the processing and placement sites used to place any applicable non-HARS material.
