The U.S. Coast Guard seeks a qualified, state-licensed contractor to replace the backflow preventer for fire hydrants on the CGC Patoka. The work must be completed within 60 days after receipt of the order, and all services will be performed at the U.S. Coast Guard Cutter Patoka. This is a firm-fixed-price construction contract set aside for total small businesses, to be awarded on a lowest-priced technically acceptable basis. Offerors must be actively registered in SAM and submit a quote addressing price, technical approach, and past performance. All materials and installation must meet or exceed state codes and industry standards, with all work coordinated through the designated Contracting Officer's Representative.
