NIGP 75014: Caliche

NIGP 75014 Caliche, an Item code, covers the supply of crushed caliche and related materials for road construction, pavement rehabilitation, and related infrastructure projects procured by state and local agencies. State and local governments use this code to source raw caliche materials for base course preparation, pavement patching, and dust control on roadway projects, typically as a component of larger construction contracts or standalone material supply agreements. Issuing bodies span county transportation departments, municipalities, and regional transportation authorities, with recent activity concentrated among county road and maintenance divisions in Texas and California.

Recent opportunities show caliche procurement emerging alongside comprehensive pavement rehabilitation work. Henderson County, Texas issued ITB 260704 on July 13, 2026 (due August 11, 2026) for crushed caliche alone, indicating standalone material sourcing. Santa Clara County, California, has posted multiple related pavement projects—the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard (ITB ITBRDAFY260694, due May 21, 2026) and an Expressway Guardrail Replacement and Safety Barrier Improvements solicitation (ITB ITBRDAFY260652, due April 23, 2026)—both of which involve asphalt overlay, recycled asphalt concrete, and base course work where caliche supply may be embedded. Barrow County, Georgia solicited resurfacing of Wynn Lake Road (ITB PE77075NONST2026000000014, due March 18, 2026) with recycled asphaltic concrete and crack relief interlayer placement. Activity is concentrated in Texas and California, with secondary presence in Georgia.
