UNSPSC 20121110: Cement retainers

UNSPSC 20121110 Cement retainers is a Commodity code that maps to procurement of prestressed concrete ground storage tanks and associated structural components for municipal water systems. State and local governments buy these tanks as capital infrastructure assets, with recent solicitations emphasizing prestressed composite tank construction, deep foundation systems, mixing equipment, piping, and appurtenant systems. The work is highly specialized, requiring tank contractors with demonstrated experience in wire-wound circular prestressed composite tank fabrication and installation. Issuing bodies are municipal utilities departments — specifically city water systems managing regional storage infrastructure — and the vendor pool is restricted to manufacturers meeting stringent prequalification criteria including documented prior performance on similar projects and structural guarantees.

Recent activity concentrates in Georgia, with the City of Calhoun soliciting a two-million-gallon prestressed concrete ground storage tank at Fire Tower Road (Brogdon) under IFB PE76500NONST2026000000021, due June 18, 2026, and the City of Marietta (Cobb County) soliciting a five-million-gallon tank replacement including demolition of an existing 4.3-million-gallon steel tank under PE66365NONST2026000000031, due February 24, 2026. Bidders on the Calhoun project must demonstrate a minimum ten years' experience in wire-wound circular prestressed composite tanks and at least five completed dome-covered tanks in service; acceptable manufacturers are restricted to CROM Corporation, PreCon Corporation, or engineer-approved equivalents. Performance and payment bonds equal to one hundred percent of contract price are required. The Marietta project similarly requires qualified contractors and includes mandatory site visits and pre-bid meetings. Both projects are locally funded with no federal involvement.
