NIGP 75014: Caliche

NIGP 75014 Caliche, an Item code, encompasses bulk caliche — both pit-run and crushed grades — supplied as base material for road construction, pavement rehabilitation, and infrastructure projects, along with readymix concrete and aggregates bundled into master agreements covering multiple material types. State and local governments procure caliche primarily through ITB and master-agreement vehicles from county transportation departments, municipal public works and utilities divisions, and special-purpose sanitation districts. Recent solicitations show caliche being specified as stabilized base course material in pavement rehabilitation work and as standalone supply items through blanket purchasing agreements that allow jurisdictions to call off material as needed throughout a contract year.

Caliche procurement activity appears concentrated in Texas and California. Hunt County and Henderson County, Texas have each issued recent ITBs for pit-run and crushed caliche respectively; the City of Midland, Texas is procuring a FY 2027 Concrete and Caliche Master Agreement due September 23, 2026, which bundles fourteen line items including stabilized caliche base with readymix concrete in multiple grades and aggregates; Santa Clara County, California issued an ITB for the Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 due September 17, 2026, which includes sewer infrastructure rehabilitation work; and Santa Clara County also solicited the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard due May 21, 2026, encompassing extensive pavement work including recycling, overlay, and curb replacement. The Midland procurement applies a local-vendor preference under Texas Local Government Code 271.9051, allowing the City to award to local bidders whose bids fall within 5% of the lowest non-local bid if the City Council determines superior value.
