The project scope involves the mobilization, demolition, and removal of eight existing 6-inch backflow preventers and three 6-inch T-fittings, followed by the installation of one 6-inch reduced pressure zone backflow preventer assembly and seven 6-inch double check detector assemblies, including necessary T-fittings. The estimated magnitude of the project is between $100,000 and $250,000, and the work must be completed within 90 days after the Notice to Proceed, with a performance period scheduled from September 30, 2026, to December 31, 2026. This acquisition is a total small business set-aside under NAICS code 238220, with a size standard of $19 million. Quotations must be submitted by September 24, 2026, and must include a completed SF 1442, the pricing schedule, a past performance questionnaire covering five relevant contracts from the last five years, a written technical approach with supporting documentation, and a bid bond if the quote exceeds $150,000. The contract is subject to the Davis-Bacon Act, requiring compliance with prevailing wage determinations for Maricopa County, and includes requirements for performance and payment bonds. Evaluation will be based on the technical approach, past performance, and price reasonableness.
