NIGP 75580: Concrete and Mortar Mixers

NIGP 75580 Concrete and Mortar Mixers, Item code, names equipment and materials that state and local governments procure for infrastructure repair, pavement rehabilitation, and construction projects—though recent solicitations show the code activity centers on concrete supply and placement services rather than mixer equipment itself. Cities, counties, and state transportation departments dominate the issuing bodies, with Utah Department of Transportation (UDOT), Santa Clara County, City of Atlanta, and City of Bend appearing as repeat buyers across multiple recent opportunities. Representative recent work includes the City of Bend, Oregon RFQ for commercial-grade concrete supply on an on-call basis (May 8, 2026 response deadline, annual value not to exceed $85,000 per year over three years), the City of Palo Alto RFQ for Portland cement concrete materials delivery within four hours of notification (February 17, 2026 response deadline, annual value $85,000), and Appling County's invitation for bids on roadway improvements with cement-treated base and asphalt paving components (August 3, 2026 response deadline, with mandatory pre-bid conference July 14, 2026).

Geographic activity clusters in the West and Southwest, with heavy recent concentration in California (Santa Clara County, City of Bend), Utah (UDOT Region 2, Region 3, and Region 4 projects), Georgia (City of Atlanta Department of Transportation, Appling County), and Texas (City of Buda). Most solicitations are issued as IFBs or RFQs under unit-price or lump-sum bid structures with firm fixed pricing and no escalation provisions; liquidated damages ranging from $500 to $1,000 per calendar day are standard for schedule delays. Suppliers must deliver within specified timeframes (often 80 minutes after batching for ready-mix concrete), maintain CSTT and QCT technical certifications for quality control, and comply with state standard specifications (GDOT, UDOT, Caltrans, Oregon) and prevailing wage requirements where applicable. Insurance minimums typically include $1 million to $2 million general liability per occurrence and $2 million to $3 million aggregate, with workers' compensation and pollution liability required in some jurisdictions. No consistent set-aside designations appear across the opportunities, though Texas HUB certification preferences, DBE participation requirements, and resident bidder status qualifications are present in selective jurisdictions.
