UNSPSC 24111817: Cement silo

A tall cylindrical storage facility that stores dry, bulk cement, a raw ingredient of concrete. It is water proof and moisture proof, and has a device for loading or dispensing the cement.

UNSPSC 24111817 Cement silo, a Commodity code, spans purchase of bulk cement and concrete storage and conveyance equipment for state and local infrastructure projects. Recent solicitations show a gap between the code's nominal scope and actual procurement activity: the Charlotte Department of Transportation solicited Portland cement as a material input for street maintenance (sidewalk installation, curb and gutter work, driveway repair, traffic signal and pedestrian signal foundations, and accessible ramp construction), while the City of Calhoun Utilities Department issued two related solicitations for design and construction of a two-million-gallon prestressed concrete ground storage tank. The Charlotte opportunity involves cement supply; the Calhoun opportunities involve tank construction and fabrication, not cement silo procurement per se. State and local issuing bodies using this code include municipal transportation and utilities departments.

The City of Charlotte, North Carolina and the City of Calhoun, Georgia show recent activity. Charlotte posted an Invitation for Bid (ITB) for Portland cement with a due date of November 3, 2026 (Solicitation 2692027029). Calhoun issued two solicitations for the 2MG ground storage tank project — the first due June 18, 2026 (Solicitation PE76500NONST2026000000021), subsequently postponed and reissued with an Addendum No. 2 moving the bid opening to October 6, 2026 (Solicitation PE76500NONST2027000000025). The Calhoun tank project requires bidders to hold a valid Georgia Utility Contractor license, employ a certified Utility Manager, and meet specialized prequalification criteria including minimum ten years of experience in prestressed composite tanks and five completed dome-covered installations. Acceptable tank manufacturers are CROM Corporation, PreCon Corporation, or engineer-approved equivalents. The discrepancy between code scope and actual solicitations suggests this code captures cement and tank-related procurement inconsistently or that issuing bodies tag material inputs under equipment codes.
