Key requirements specify environmentally safe releasing agents, adherence to USCG Drawing Number 121206 for dimensions, and cured sinkers within -3% or +10% of design weight. Concrete must be ready-mix with a minimum compressive strength of 3000 psi at 28 days and weigh at least 140 pounds per bulk cubic foot. Materials must conform to ASTM standards (C 150, C 33), with slump between 2 and 5 inches (ASTM C 143). Workmanship, placement, and curing must follow ACI 318, with a minimum three-day curing period before moving.

The Coast Guard Shore Director of Operational Logistics Command (LOG-95) has issued a Sources Sought Notice (70Z8426QWOPL0002) to identify capable sources for fabricating and delivering 1,000 lb., 1,500 lb., and 2,000 lb. concrete sinkers for U.S. Coast Guard Buoy Tenders across the Midwest. The requirement is divided into three geographical areas: Ohio River Valley, Upper Mississippi Valley, and Lower Mississippi River Valley, with historical ordering data indicating substantial demand in each. The USCG anticipates awarding up to three single awards, one per area, for a base year plus four option years, starting around June 10, 2026. The applicable NAICS code is 327331 (Concrete Block and Brick Manufacturing) with a 500-employee small business size standard. A small business set-aside determination will be made based on responses to this notice. Interested parties must complete and submit a questionnaire via email by December 19, 2025, at 3:00 p.m. EST.
