USACE’s Arkabutla Lake Project seeks one firm-fixed-price contract under a 100% small-business set-aside for water plant rehabilitation and prefabricated metal building installation. The contractor will abandon the old well; install new plumbing, valves, chemical pump, air compressor, and related fittings; purchase/deliver/install a 30’x50’ red-iron open-span metal building with stamped drawings; sandblast/paint the tank; and install specified electrical work. USACE personnel will remove the old building before delivery and installation, and the contractor must provide all supervision, labor, tools, equipment, and materials. Delivery and installation must be completed no later than 120 days after award. The NAICS code is 332311 with a 750-employee size standard, and the government intends to award one firm-fixed-price contract, potentially without discussions.
