The U.S. Coast Guard is conducting a sources-sought market survey for a Design-Build contract to repair storm sewer lines at Coast Guard Base San Juan, Puerto Rico. The work includes field verification of utilities and existing conditions, hazardous waste determination, material sampling, design drawings/specifications, construction scheduling/phasing, and repair/cleaning of storm sewer inlets, catch basins, culverts, and pipes. The design and construction performance period is 290 calendar days, with tentative contract performance completion in September 2027. The estimated procurement value is between $1,000,000 and $5,000,000, and bid, payment, and performance bonds are required. The Coast Guard is considering a HUBZone, VOSB, SDVOSB, or WOSB set-aside and seeks responses from interested small businesses with relevant experience, bonding capability, and SAM registration.
