NIGP 21011: Blocks, Hollow and Solid, Normal Weight

NIGP 21011 Blocks, Hollow And Solid, Normal Weight is an Item code under which state and local governments procure concrete and masonry blocks for infrastructure, utility, and facility renovation work. Recent opportunities show municipalities and special districts sourcing concrete blocks for sewer infrastructure repairs, truck dumping areas, and building renovations. The issuing bodies include city public works and utility departments, county sanitation districts, and facility operators. The City of Austin's Austin Resource Recovery department and Santa Clara County's Sanitation District No. 2-3 have solicited concrete blocks for distinct applications: Austin requested 44 concrete bin blocks measuring 2 feet by 2 feet by 6 feet for a truck dumping area, while Santa Clara County specified new 48-inch diameter precast concrete sanitary sewer manholes and fittings as part of a sewer mainline extension and repair project. Work solicited under the code tends to be embedded in larger capital projects—sewer rehabilitation, facility renovations, and public works infrastructure—rather than standalone block procurement.

Geographic activity centers on Texas and California, with the City of Austin, City of San Antonio, and Santa Clara County appearing in recent solicitations. The City of Austin issued an IFQ for steel sheeting and concrete bin blocks due October 7, 2026, for immediate delivery by October 22, 2026, requiring FOB Destination pricing and a Certificate of Insurance. Santa Clara County solicited bids via ITB for structural sewer repairs including concrete precast components, with bids due September 17, 2026, and a sixty-five working day completion window from Notice to Proceed. These opportunities typically nest within larger construction or infrastructure projects and require vendors to integrate their material supply with broader site delivery and project management frameworks. Concrete blocks appear as line items in comprehensive renovation and infrastructure packages rather than as standalone commodity buys.
