Grsa clean and inspect water tank

The National Park Service Intermountain Region is procuring cleaning and inspection services for two potable water storage tanks at Great Sand Dunes National Park & Preserve in Mosca, Colorado. The project requires comprehensive maintenance of a 50,000-gallon welded steel tank and a 74,000-gallon glass-fused-to-steel tank, including interior inspections using ROV or divers, exterior assessments, shell thickness testing, sediment removal up to 3 inches, and detailed reporting with photographs and recommendations. Contractors must demonstrate at least five years of experience with glass-fused-to-steel bolted liquid storage tanks, particularly those manufactured by Aqua Store, and comply with OSHA, EPA, AWWA, and NFPA standards. The solicitation will be awarded based on best value consideration of both price and technical capabilities, with emphasis on the contractor's project approach, cost management, and specific technical competence. Amendment P00001 has extended the quote submission deadline to August 26, 2025, at 1100 Mountain Daylight Time, with quotes to be submitted to Billie Thomas at the National Park Service.

This opportunity is designated as a 100% total small business set-aside under NAICS code 561990 with a size standard of $17 million, and no incumbent contractors are identified in the solicitation documents. The contract performance period extends from September 1, 2025, to August 24, 2026, though no specific award values or budget ranges are disclosed in the available documentation. The work will be performed at the Great Sand Dunes National Park visitor center area located at 11500 State Highway 150 in Mosca, Colorado, where both water storage tanks are situated near existing water infrastructure. The project may require two separate site mobilizations due to testing and refilling requirements, and contractors must follow strict disinfection protocols and conduct bacteriological examinations after cleaning completion. Interested offerors must maintain current registration in the System for Award Management (SAM) and possess a Unique Entity Identifier (UEI) to be eligible for award consideration.
