UNSPSC 12162300: Curing agents

UNSPSC 12162300 Curing agents, a Class code, encompasses concrete-related materials and services that state and local governments procure to support construction, repair, and maintenance of concrete infrastructure. Recent solicitations show that the code captures not just chemical additives but the full constellation of ready-mix concrete delivery, precast concrete products, concrete repair services, and specialized concrete work—from routine as-needed supply contracts to capital projects involving concrete pads, sidewalks, and structural elements. State and local issuing bodies include city public works and operations departments, county transportation and utilities authorities, school districts, water utilities, and fire departments. The mix spans small routine maintenance suppliers to specialized contractors managing complex concrete rehabilitation and new construction.

Procurement activity clusters in Florida, California, Georgia, Texas, Kansas, Kentucky, Mississippi, Arizona, Michigan, and Oregon, with the heaviest recent posting volume in Florida (Volusia, Pasco, Orange, Indian River counties and multiple cities), followed by California and Texas municipalities. Representative recent opportunities include the City of Santa Cruz Fire Department's IFB for concrete pad installation supporting a metal storage building (sealed bids electronically due July 29, 2026 at 2:00 p.m. with mandatory pre-bid July 1, local business preference 2–6%, prevailing wage compliance required); Kissimmee Utility Authority's rebid for precast concrete pads, sleeves, and posts on an as-needed fixed-price basis (bids due August 11, 2026, 476 units over five years, 100% performance bond required); the City of Olathe's IFB for ready-mix concrete furnishing and delivery across five concrete types totaling approximately 4,720 cubic yards (bids due August 21, 2026 at 10:00 a.m. CST, local-vendor preference within Johnson County up to 2% or $5,000); and the City of Arlington's RFP for annual concrete repair services including overlays, new installations, and polyurethane-foam pavement leveling (proposals due August 20, 2026). Most active issuing bodies are county transportation departments and municipal public works offices managing ongoing as-needed supply relationships; pre-selected vendor arrangements and prevailing wage compliance appear consistently across fire department and utility projects. Contract structures typically run one to five years with optional renewals, and award almost uniformly goes to the lowest responsive and responsible bidder.
