NIGP 75091: Stabilized Base

NIGP 75091 Stabilized Base, an Item code, covers the supply and installation of base course materials used in road and infrastructure construction and rehabilitation projects. State and local governments procure stabilized base as part of pavement rehabilitation, roadway construction, and utility infrastructure work. Recent solicitations show issuing bodies applying this material in comprehensive pavement overlays, utility mainline extensions, and curb-and-gutter installations across counties and special-purpose districts. The code encompasses material supply, labor, equipment, and installation services for preparing stable foundation layers beneath asphalt, concrete, and utility infrastructure.

Santa Clara County has posted two representative opportunities under this code in 2026. County Sanitation District No. 2-3 issued an ITB (ITBRDAFY270088) on August 26, 2026 for the Structural Defect Repair Project Phase 2, a sewer infrastructure rehabilitation program in the unincorporated eastern foothills, with bids due September 17, 2026 at 2:00 p.m. local time; the scope includes sewer mainline repairs, pipe-burst replacements, and extensions in Santa Clara County requiring completion in sixty-five working days from Notice to Proceed. Santa Clara County also issued an ITB (ITBRDAFY260694) on April 29, 2026 for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026; that procurement encompasses partial depth recycling, hot mix asphalt overlay, pavement repairs, Portland cement concrete curb and gutter installation, ADA access improvements, and related work over a 142 working day timeline. Both opportunities reflect active procurement activity in California focused on utility and transportation infrastructure.
