Construction Services for Maintenance Dredging of the New Haven Harbor Federal Navigation Project, New Haven, CT.

The U.S. Army Corps of Engineers, New England District is issuing a Sources Sought Announcement for a maintenance dredging project located in New Haven, CT. This announcement is to determine the interest, availability, and capability of Small Business and Large Business concerns as described below. The NAICS code for this procurement is 237990 with a size standard of $37M. The project solicitation is planned for issuance on or about May 15, 2026. The construction will occur over 2 dredge seasons starting in October 2026 and being completed by May 2028. The estimated construction cost is between $25,000,000.00 and $100,000,000.

The New Haven Harbor Improvement project involves deepening and widening the existing navigation channel and turning basin from Long Island Sound to the Quinnipiac River. The project will deepen the current 35-foot channel to 40 feet below Mean Lower Low Water (MLLW) and widen it by 100 to 250 feet at various locations. This contract requires the removal of approximately 4,500,000 cubic yards (CY) of silt and fine sand, as well as 61,000 CY of rock that will require blasting. A mechanical dredge will excavate material from the shoaled areas and load it into dump scows. The dredged material will be transported to four designated beneficial use sites within the harbor, with the remaining volume taken to the Central Long Island Sound Disposal Site. Operations are expected to last 8 to 10 months within the project dredging window of October 1, 2026, to May 31, 2028. All dredging, filling and blasting of material north of the New Haven Harbor breakwaters must be completed between October 1 and January 31 of each dredging season to avoid sensitive resources in the harbor. All dredging, filling and blasting of material south of the New Haven Harbor breakwaters must be completed between October 1 and May 31 of each dredging season window. No work is expected to be completed between June 1, 2027, and September 30, 2027, due to sensitive resources within the harbor and Long Island Sound.

In order to accomplish all dredging requirements within the specified dredging window it is expected that the Contractor will need to meet a production rate of 550,000 CY per 30 calendar days.
