UNSPSC 12163301: Cement expanding agents

UNSPSC 12163301 Cement expanding agents is a Commodity code that covers concrete admixtures, reinforcing fibers, and specialized concrete materials used by state and local governments in infrastructure and facility maintenance. In practice, state and local procurement under this code encompasses ready-mix concrete supply contracts, concrete repair and restoration work, and precast concrete components—often bundled with broader concrete and asphalt procurement. The issuing-body mix spans county departments of road and bridge, city public works and operations departments, municipal water districts, fire departments, school districts, and transit-adjacent utility authorities. Repeat buyers include Kissimmee Utility Authority (which re-bid precast concrete pads, sleeves, and posts twice between June and August 2026 after canceling the initial solicitation), Pasco County Board of County Commissioners (which solicited both fiber-reinforced and regular ready-mix concrete on as-needed bases), and the City of Santa Cruz Fire Department (which procured concrete pad installation with utilities in back-to-back solicitations in May and July 2026). Work solicited under the code ranges from single-material purchases—Portland cement supply to Pinal County (IFB 270532, bid due September 4, 2026) and ready-mix concrete delivery to the City of Olathe (IFB-26-0083, bids due August 21, 2026 for 4,600 estimated cubic yards across five concrete types)—to integrated construction services combining concrete placement with site work, demolition, and finish operations.

Recent activity concentrates in Florida, California, and the Southwest, with secondary activity in Texas, Oregon, Kentucky, Georgia, and Mississippi. The City of Plant City (Florida) sought ready-mix concrete services on an as-needed term basis (response due July 9, 2026); Pasco County (Florida) issued two separate procurements for miscellaneous concrete and asphalt services and fiber-reinforced ready-mix concrete (proposals due August 18 and June 30, 2026); and Deschutes County (Oregon) requested bids for primary clarifier rehabilitation including floor demolition, replacement, and topping-grout work for a water treatment facility (bids due July 30, 2026, engineer's estimate $808,800 to $1,213,200). The City of Arlington, Texas solicited an annual requirements contract for concrete repair, overlay, and new installation services including polyurethane-foam pavement-leveling work (proposals due August 20, 2026). The City of Santa Cruz (California) issued two consecutive solicitations for concrete pad installation supporting fire apparatus storage—the original IFB (Fire-0301, bids due May 19, 2026) and a re-posted IFB B25-0290 (bids due July 29, 2026)—each specifying 18.15 cubic yards of 4,000+ PSI concrete with fiber mesh or rebar reinforcement and design load capacity for 55,000-pound fire apparatus, subject to California prevailing wage and Green Building Code compliance including 65 percent construction waste diversion. Kissimmee Utility Authority's rebid (AR26-050-JG, bids due August 11, 2026) for precast pads, sleeves, and posts across 16 line items totaling 476 estimated units over a five-year initial term reflects typical utility-sector standardized concrete-component procurement. Most opportunities are issued as IFB, RFQ, or RFP with response windows of two to six weeks; many impose prevailing wage, Davis-Bacon, or Green Building Code compliance; and several require performance and payment bonds at 100 percent and 50–100 percent of contract value respectively.
