Z--CLEAN WATER TANKS AT PD AND RF

The contract seeks a 100% small business set-aside under NAICS code 541380 for the inspection, cleaning, and disinfection of underground potable water storage tanks at Petrified Forest National Park, specifically one 500,000-gallon tank at the Painted Desert area and two adjoined 100,000-gallon tanks at the Rainbow Forest area. The scope requires interior inspections using ROV robots or divers, exterior inspections with OSHA-compliant fall protection, sediment removal via the same methods, and disinfection in accordance with AWWA C652-19 using liquid chlorine or sodium hypochlorite, followed by bacteriological testing through a state-certified laboratory. All work must comply with OSHA, EPA, AWWA, NFPA, NPS Public Health, and Arizona State Department of Environmental Quality standards. A comprehensive written report with photographs, a DVD of the inspection, corrective recommendations, and cost estimates must be submitted in triplicate—two paper copies and one electronic copy—in bound format within one calendar week of completion, with each binder including the inspection date, contractor contact information, and service contacts for installed components. Equipment submittals must include manufacturer data via the provided transmittal form, and a safety site plan must be approved by NPS and contracting officials before any onsite work begins. The solicitation is issued as a Firm-Fixed Price commercial RFQ on Standard Form 18 and requires a single lump-sum quote for the entire project. Offerors must be registered and active in SAM with a valid Unique Entity Identifier, and they must submit a completed SF18, signed amendments, at least three and no more than five past performance questionnaires for comparable projects, and all required certifications and representations including those for Buy American, prohibition on inverted domestic corporations, and security exclusions. The technical evaluation focuses on the offeror’s documented experience and capability to deliver all labor, materials, tools, supervision, and travel per the Statement of Work, while price is assessed for reasonableness against the independent government estimate and checked for unbalanced line items. Past performance is evaluated based on completed questionnaires confirming successful completion of similar tasks. All submissions must be emailed by 5:00 PM MDT on July 7, 2026, with late responses rejected outright. The contract period runs from July 14 to September 30, 2026, with possible extensions up to six months
