NIGP 74501: Aggregate, Precoated

NIGP 74501 Aggregate, Precoated, an Item code, covers precoated aggregate materials that state and local governments buy primarily for road construction, pavement rehabilitation, and streetscape projects. Recent solicitations show municipalities and counties purchasing precoated aggregates as components within larger construction procurements—materials such as hot mix asphalt, asphalt concrete, recycled asphalt pavement (RAP), and recycled asphalt shingles (RAS)—alongside uncoated stone, sand, and slag for base courses, surface treatments, and fill. The work spans design-build infrastructure projects, routine maintenance contracts, and vendor qualification frameworks. Issuing bodies include cities (Detroit, Temple, Pembroke Pines, Johns Creek), counties (Collin, Santa Clara, Broward, Neshoba), special districts (Sanitation District No. 2-3 in Santa Clara County), and county parks departments (Boulder County Parks and Open Space). Cities and counties dominate; repeat solicitors include Collin County, Santa Clara County, and the City of Detroit, all pursuing multi-year supply agreements or capital construction projects.

Recent activity concentrates in Texas, California, and Florida. Collin County solicited asphaltic concrete and aggregate for surface treatments under IFB #2026-280 and #2026-278 (bids due July 16, 2026) with an estimated contract value of $3 million for asphaltic concrete across eight zones with options to renew for two additional one-year terms. Santa Clara County's Central Expressway Pavement Rehabilitation Project (ITB ITBRDAFY260694, bids due May 21, 2026) and Structural Defect Repair Project Phase 2 (ITB ITBRDAFY270088, bids due September 17, 2026) both incorporate asphalt and aggregate materials within comprehensive construction scopes. The City of Detroit's RFQ 546989 for fine and coarse aggregate materials (11,000 tons; quotes due June 5, 2026) and RFQ 548310 for asphalt pick-up (3,000 tons of Bituminous Aggregate Wearing Course 36A; quotes due June 29, 2026) demonstrate active city-level procurement. Boulder County Parks and Open Space solicited landscaping and erosion control materials including aggregates under SOQ28626 (proposals due May 27, 2026) on a five-year pre-qualified vendor list structure. The City of Temple budgeted $120,000 for an annual aggregate base agreement (BID340427, bids due August 20, 2026), while the City of Johns Creek (Georgia) issued ITB 27-314 for streetscape improvements including asphalt pavement and concrete work (bids due November 10, 2026). Payment terms typically run Net 30; most solicitations require bid bonds (5%), performance bonds (25–100% of contract value), and commercial general liability insurance ($1–2 million per occurrence). Multi-year terms and primary/secondary vendor awards are common.
