Maintenance Dredging of New York Harbor, Sandy Hook Federal Navigation Channel

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 Harbor, Sandy Hook Federal Navigation Channel.

The dredged material would be dredged and subsequently transported to and placed at the Sea Bright Offshore Borrow Area (SBOBA), 5 miles southeast of Sandy Hook Point, NJ, and a stockpile placement at Lot J of the National Park Service (NPS) Sandy Hook

Gateway National Recreation Area or at other stockpile site(s) identified by NPS. All stockpile site(s) are subject to change at the discretion of NPS and/or USACE. The proposed maintenance dredging would remove approximately 200,000 cubic yards of selected critical shoals from the Sandy Hook Channel. An estimated 15,000 to 20,000 CY of dredged material would be placed within the stockpile site identified above. Dredging would be required to a depth of -35 feet Mean Lower Low Water (MLLW) plus 2 feet of allowable overdepth. The dredged material is expected to consist primarily of sand and gravel.

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 and tugboats will be needed to perform the work during the dredging, transport and unloading operations. Placement at the stockpile site(s) may require scow, barge, or similar equipment with pump out capabilities. 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.

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 8,000 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 Fall and winter of 2025/2026.

The work is estimated to cost between $1,000,000.00 and $5,000,000.00.

SURVEY OF THE DREDGING INDUSTRY

The following confidential survey questionnaire is designed to apprise the Corps of prospective dredging contractors’ project execution capabilities. Please provide your response to the following questions. All questions are regarding to the New York Harbor, Sandy Hook Channel maintenance dredging project.

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, as a reference of relevant experience.

2) Do you have experience with the placement of dredged material at the SBOBA?

Please list your experience.

3) Do you have experience with the placement of dredged material at stockpile site(s)? Please list your experience.

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

5) Have you performed dredging within the coastal waters of New Jersey?

6) Would you be willing to bid on the project described? If the answer is no, please explain why not.

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

8) Is there a dollar limit on the size of contract that you would bid? If so, what is that limit?

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

10) What is your bonding capacity per contract? What is your total bonding capacity?

11) Do you have experience using the USACE Resident Management System (RMS 3.0) for delivering Submittals, Daily Dredging reports and Pay Estimates?

12) Do you have experience applying the USACE EM 385-1-1 (Nov 2014) and all requirements? Deficiencies observed on site will require immediate attention and action to meet all applicable safety codes.

Equipment

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

14) 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, bottom dump, etc.) and the capacity.

15) Will you be able to meet a production rate of 8,000 cubic yards per calendar day with placement at the SBOBA or for placement at a designated stockpile site(s)?

16) Do you own or have the capabilities of pumping dredged material from a scow, barge, or similar equipment, after it has been dredged mechanically? If so, please explain the equipment needed and the process.

a. Please list projects at which this method of placement was utilized.

Specify if any of the projects were USACE projects.

b. Would you be able to pump dredged material from a scow/barge/similar equipment onto a stockpile site similar to Lot J, an unpaved parking lot at the NPS Sandy Hook National Recreation Area? This stockpile site is subject to change at the discretion of NPS and/or USACE.

i. The dimensions of the Lot J unpaved parking lot are approximately 315 feet by 180 feet. How much dredged material would you be able to place within the area and to what maximum height?

ii. How much pipeline would you need to place at Lot J? Do you anticipate requiring a booster pump? Where would the scow be docked when pumping to the stockpile site?

iii. How much area (square footage) of Lot J would be needed as a dewatering site for the dredged material?

iv. Please provide a visual representation of a potential pump out operation to Lot J by utilizing Figure 1. Include the potential scow location, path of pipeline to Lot J, booster pump location(s), staging site, and dewatering site. This will be used for informational purposes only.

v. What would be the approximate percentage of cost differential when comparing the cost of placement at SBOBA to the cost of stockpile placement at Lot J? The cost differential would be used for planning purposes only.

vi. What are some factors that may affect the cost difference between placement at SBOBA and stockpile placement at Lot J?

vii. If Lot J is not a suitable stockpile placement site, please provide reasons why.

17) Do you have experience with the use of an automated Dredged Material Monitoring

System (Black Box/Silent Inspector) or employing a Dredged Material Inspector

(DMI)?
