UNSPSC 30131505: Haydite block

UNSPSC 30131505 Haydite block is a Commodity code that in recent state and local procurement reflects solicitation for concrete masonry units and related building materials used in infrastructure rehabilitation and construction projects. Santa Clara County's Central Expressway Pavement Rehabilitation Project—the only recent opportunity tagged to this code—is a comprehensive roadway reconstruction effort rather than a discrete haydite block procurement, suggesting the code may be capturing a minor material component within larger, broader-scope infrastructure work rather than standalone masonry supply. The county solicited qualified contractors to supply labor, materials, and equipment for pavement rehabilitation including partial depth recycling, hot mix asphalt overlay, pavement repairs, Portland cement concrete curb and gutter installation, curb ramp and sidewalk replacement and new installations, ADA access improvements, pavement markings and striping, roadway signs, guardrail system replacement, bioretention basin installation, traffic signal modifications, pedestrian sensor installation, and inductive traffic loop removal and replacement. The work is being solicited through an Invitational, Competitive Sealed Bid (ITB) notice by a county government rather than a state department, school district, or transit authority.

Santa Clara County posted the Central Expressway Pavement Rehabilitation Project solicitation (ITBRDAFY260694) on April 29, 2026, with a response deadline of May 21, 2026, requiring physical bid submissions to the County Clerk of the Board of Supervisors at the County Government Center in San Jose, California. The project timeline requires completion within 142 working days from the first charged day, anticipated 30 to 45 days following Notice of Award. The solicitation document does not specify project budget, set-aside designations, or preferential procurement criteria. Recent activity under this code appears limited to this single California county opportunity; no other recent state or local haydite block procurements are evident in the source, suggesting minimal current demand or alternatively that this code is infrequently matched to relevant solicitations in state and local procurement systems.
