This is a market survey by the U.S. Coast Guard, not a solicitation, to determine interest in a potential small business set-aside for modernizing mooring infrastructure at three locations: New Haven, CT; Southwest Harbor, ME; and South Portland, ME. The estimated budget for the project is between $5,000,000 and $10,000,000, covering corrosion mitigation, structural repairs, safety enhancements, and utility upgrades. A single contract is anticipated, with work phased across the three sites. Interested vendors must demonstrate bonding capacity and relevant past performance, with a response requested by a specified deadline. No contract will be awarded from this announcement, and no reimbursement for costs will be provided.
