Description

The U.S. Army Corps of Engineers, New England District is issuing an Invitation for Bids on behalf of the United States Navy (USN) for maintenance dredging of two portions of the Federal Navigation Project (FNP) in the lower Kennebec River, Maine. This will be an unrestricted competitive IFB procurement requiring a hydraulic hopper dredge to perform the work. The NAICS code for the work is 237990 with a size standard of $37M. The construction will extend over a 3-4 week period. The estimated construction cost is $1,000,000 to $5,000,000. Any responsible source meeting this standard may submit a bid to be considered by the New England District. The work involves maintenance dredging for the USN of two portions of the authorized, 27-foot deep, 500-foot wide FNP in the lower Kennebec River. Dredging is required to meet the navigational requirements of newly constructed surface combatants being built and tested at Bath Iron Works.  The work will restore the channel to its authorized dimensions and involves removal of a total of about 50,000 cubic yards (cy) of clean sand. Approximately 40,000 cy of material will be removed from the Doubling Point area (i.e., just below Bath) and approximately 10,000 cy of material will be removed from the Popham Beach area (at the river mouth). As part of this proposal, maintenance dredging will be performed to remove the sand-waves in the vicinity of Doubling Point to a maximum elevation of -34 feet MLLW to improve the chance that adequate depths will endure. The 40,000 cy to be removed from the channel at Doubling Point includes approximately 30,000 cy of advance maintenance dredging. Material dredged from the Doubling Point area will be placed in the previously used in-river disposal area north of Bluff Head in about 95-100 feet of water. Material dredged from the Popham Beach area will be placed at the previously used Jackknife Ledge placement site in about 40-50 feet of water. The dredging and dredged material placement work is expected to take 3-4 weeks to complete. The available work window for the dredging and placement of dredged material is from 1 December 2024 to 1 March 2025.
