Introduction and Purpose: The USACE Jacksonville District is issuing this RFI to conduct market research and solicit information from the dredging industry on the feasibility of utilizing mechanical dredges to maintain the Naval Submarine Base Kings Bay Entrance Channel in St Mary’s, Georgia. The applicable North American Industry Classification System (NAICS) code assigned to this procurement is 237990, Other Heavy and Civil Engineering Construction.

The Small Business Size Standard for this project is $45.0 million Project Background: The Naval Submarine Base Kings Bay Entrance Channel is a critical waterway that requires periodic maintenance dredging to ensure safe navigation for naval vessels. Currently, maintenance dredging is performed by hopper dredges, which are restricted to a working window from December 15 to March 31. These hopper dredges are capable of working throughout the entire channel. The Jacksonville District is exploring the use of mechanical dredges as a potential supplement to the existing dredging operations.

Challenge and Constraints: The use of mechanical dredges in the Kings Bay Entrance Channel presents specific challenges:

Operational Limitations: It has been determined that mechanical dredges cannot safely operate beyond channel station 71+00 Cut-1N.

Tidal Currents: There is a significant concern regarding the impact of strong tidal currents on the safety and effectiveness of mechanical dredging operations, particularly for operations inland of channel station 71+00 Cut-1N.

Information Requested: The Jacksonville District is seeking responses from the dredging industry to the following questions:

Feasibility: Based on your experience, is it feasible to utilize a mechanical dredge for maintenance dredging of the Naval Submarine Base Kings Bay Entrance Channel, specifically inland of channel station 71+00 Cut-1N? Please provide the basis for your assessment.

Tidal Current Mitigation: What are the primary risks associated with operating a mechanical dredge in an environment with significant tidal currents? What specific methods, equipment, or operational procedures would you recommend to mitigate these risks?

Equipment and Configuration: What type and configuration of mechanical dredging plant (e.g., barge size, crane capacity, bucket type) would be best suited for this project, considering the channel conditions and tidal currents?

Demobilization from the Channel: How much time is required to demobilize mechanical dredge plants and all supporting floating plant and equipment from the channel to allow naval vessels to pass? How much time is required to remobilize and recommence dredging?

Additional Information: Please provide any other relevant information, insights, or recommendations that you believe would be valuable for the USACE to consider in its assessment of mechanical dredging for this location.

Submission Instructions: Provide Firm's name, address, point of contact, phone number, website, and email address. Responses to this RFI must be received no later than 2:00 PM, EDT, on 13 April 2026 and shall be sent to Walter Love at walter.d.love@usace.army.mil and Manuela Voicu at manuela.d.voicu@usace.army.mil.
