Concrete Sinkers for Buoy Tenders

The U.S. Coast Guard is seeking qualified vendors to fabricate and deliver concrete sinkers in three weight classifications (1,000 lb., 1,500 lb., and 2,000 lb.) for buoy tenders operating in the Heartland District areas. This pre-solicitation notice is being issued to conduct market research and identify potential sources prior to formal solicitation. The procurement requires contractors to meet strict technical specifications including minimum 3,000 psi compressive strength concrete, ASTM A36/M steel lifting eyes, and compliance with multiple ASTM and ACI standards for composition and testing. Contractors must demonstrate production capability, relevant experience with similar contracts within the past five years, and maintain facilities capable of meeting progressive delivery milestones. The questionnaire response deadline is December 19, 2025 at 3:00 p.m. EST, with submission required electronically to designated Coast Guard contract specialists. The anticipated contract award date is June 10, 2026, and this notice does not constitute a formal solicitation but rather a sources sought exercise to assess market capacity and interest.

This procurement is set aside as a Total Small Business opportunity under NAICS Code 327331 (Concrete Block and Brick Manufacturing) with a small business size standard of 500 employees. No incumbent contractor is identified in this pre-solicitation notice. The Coast Guard anticipates making up to three single awards, with one contractor potentially selected per geographic region (Ohio River Valley, Upper Mississippi Valley, and Lower Mississippi River Valley), based on historical ordering data ranging from 10,000 to 20,000 sinkers per area over the previous five years. The contract will be structured as a one base year plus four option year arrangement, extending performance through June 2031. Interested parties must be registered in the System for Award Management (SAM) and may qualify for special designations including 8(a), HUBZone, Woman-Owned, Veteran-Owned, or Service-Disabled Veteran-Owned Small Business status. Delivery requirements are strictly defined with progressive milestones requiring 20% delivery within 30 days, 40% within 60 days, 60% within 90 days, 80% within 120 days, and 100% completion within 150 days of contract award.
