NIGP 15035: Hardeners, Concrete and Plaster

NIGP 15035 Hardeners, Concrete and Plaster is an Item code under which state and local governments procure ready-mix concrete delivery, concrete pads and sidewalk installation, concrete repair and resurfacing, and related concrete hardening materials for maintenance, construction, and infrastructure projects. Recent solicitations show municipalities and counties contracting for as-needed ready-mix concrete supply (the City of Jackson, City of Plant City, Pasco County, City of Bradenton, and County of Volusia), concrete pad installation with utilities for fire station buildings (City of Santa Cruz), concrete sidewalk removal and replacement (City of Madison, City of Fairburn, Town of Waterford), and concrete pavement work including curbs, gutters, and ramps (Orange County for ADA pedestrian safety improvements, County of Ventura Harbor, City of Owensboro). Issuing bodies span city public works departments, county boards of commissioners, transit authorities (Charlotte Area Transit System), and special districts (City of Santa Cruz Fire Department, Ventura Harbor Department). The code attracts work from cities and counties nationwide, with recent activity concentrated in Florida (Volusia County, Plant City, Pasco County, Bradenton, Orange County, Pembroke Pines), California (Santa Cruz, Ventura County, Fairburn), and scattered activity in Wisconsin (Madison), Connecticut (Norwalk, Waterford), Georgia (Fairburn), Kentucky (Owensboro), Michigan (Jackson), Oregon (Deschutes County), and Texas (Williamson County, Harlingen ISD).

Representative recent opportunities include the City of Santa Cruz Fire Department issuing an IFB for concrete pad installation and utilities at Fire Station #3 (18.15 cubic yards, bids due July 29, 2026, local business preference 2–6%), the City of Jackson issuing an RFP for ready-mix concrete continuous delivery services with Davis-Bacon and Section 3 compliance (responses due June 18, 2026), Orange County, Florida issuing a term contract RFP for ADA pedestrian safety improvements encompassing concrete sidewalks, curb ramps, and drainage at an estimated value of $6.255 million (bids due May 7, 2026), County of Volusia issuing an ITB for ready-mix concrete products in multiple grades delivered within the county (responses due April 23, 2026, local preference 3–5%), and the City of Palo Alto issuing an RFQ for Portland Cement Concrete on a three-year blanket purchase order basis (annual cap $85,000, responses due February 17, 2026). Concrete material procurement at this code attracts significant volume from municipalities maintaining capital budgets for pedestrian infrastructure, emergency services facilities, and routine pavement maintenance; prevailing wage and Davis-Bacon compliance requirements appear frequently in publicly funded work.
