NIGP 21011: Blocks, Hollow and Solid, Normal Weight

NIGP 21011 Blocks, Hollow And Solid, Normal Weight is an Item code representing concrete building materials and infrastructure components that state and local governments procure for transportation, utilities, and site-development projects. Recent solicitations show municipalities and counties buying precast concrete products including catch basins, endwalls, infiltration systems, reinforced concrete pipe, drainage pipe, and associated drainage infrastructure; in parallel, transportation agencies are acquiring concrete curb, gutter, and sidewalk materials for roadway reconstruction and pavement rehabilitation work. Issuing bodies include cities (Austin, Salem), counties (Santa Clara), and towns (Glastonbury) — each deploying this code for capital infrastructure projects spanning roundabout construction, streetscape reconstruction, and parking-lot improvements. The code captures both materials procurement (precast components and pipe) and integrated construction contracting where concrete materials and labor are bundled in a single bid.

Recent opportunities span California, Oregon, and Connecticut. The City of Austin posted IFB 6100CLMC1160 on June 8, 2026, due July 9, 2026, for the Rutland/Parkfield Roundabout project under the 2022 SS4A program, requiring conversion of a signalized intersection with ninety working days to substantial completion, MBE/WBE compliance plans, and liquidated damages of $1,330 per calendar day; Santa Clara County issued ITB ITBRDAFY260694 on April 29, 2026, due May 21, 2026, for the Central Expressway Pavement Rehabilitation Project including Portland cement concrete curb, gutter, sidewalk, and pavement repairs over 142 working days; the City of Salem released a sealed-bid RFP (Contract 256107) on February 18, 2026, due March 17, 2026, for Streetscape Improvements Phase V spanning four downtown street segments with an engineer's estimate of $1,854,000 to $2,368,000 and substantial completion by September 30, 2026; and the Town of Glastonbury solicited competitive bids on March 10, 2026, due March 31, 2026, for precast materials including infiltration systems, catch basins, reinforced concrete pipe, and precast light pole bases for parking-lot improvements at 50 Nye Road.
