UNSPSC 30131511: Concrete armor unit

A block built to protect a breakwater or a coastal structure by weakening wave energies.

UNSPSC 30131511 Concrete armor unit is a Commodity code that designates specialized concrete protective components used in infrastructure projects, though recent state and local solicitations under this code focus primarily on comprehensive pavement rehabilitation and roadway improvement work rather than discrete concrete armor units in isolation. Santa Clara County and similar transportation infrastructure procurement bodies solicit concrete and related materials as components within broader construction and rehabilitation projects that encompass asphalt overlays, concrete curbing and gutters, sidewalk and ramp installations, and associated site work. The issuing bodies sourcing under this code include county departments of transportation and public works, which integrate concrete armor and reinforcement materials into multi-phase roadway projects alongside labor and equipment procurement.

Santa Clara County issued an ITB (Invitation to Bid) on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026, requiring physical submission to the County Clerk of the Board of Supervisors in San Jose. The project scope includes partial depth recycling, hot mix asphalt overlay, pavement repairs, Portland cement concrete curb and gutter installation, curb ramp and sidewalk replacement, ADA improvements, traffic signal modifications, bioretention basin installation, and guardrail system replacement, with a 142 working day completion timeline commencing 30 to 45 days after Notice of Award. The solicitation does not disclose a specific project budget, set-aside designations, or vendor preference criteria. Geographic activity is concentrated in California, with Santa Clara County representing the most recent documented procurement under this code, though the limited recent-opportunity data does not support characterization of broader regional distribution.
