UNSPSC 31163104: Mechanical rebar connector or splice

A device used to join lengths of rebar together.

UNSPSC 31163104 Mechanical rebar connector or splice is a Commodity code that in practice encompasses connectors, splices, and fastening products used in underground utility infrastructure rehabilitation—particularly sewer and water main repair, replacement, and extension projects where pipe joints, connections, and structural elements require secure mechanical coupling. State and local governments procure these products as components within broader infrastructure construction and rehabilitation contracts rather than as standalone items, embedded in bid packages alongside pipe materials, fittings, and labor. The issuing bodies are primarily county sanitation districts, county public works departments, and regional water authorities managing aging utility systems in suburban and unincorporated areas; these entities post infrastructure rehabilitation work on unit-price or lump-sum IFB and ITB bases with performance timelines measured in working days to months.

Recent activity concentrates in California and Florida. Pinellas County, Florida posted an IFB on October 12, 2026 (Solicitation 260652ITBC, response October 13, 2026, final bids November 5, 2026) for coordinated sewer and water main replacement in the City of Seminole involving approximately 500 linear feet of 12-inch PVC sanitary sewer pipe, six 4-foot diameter manholes, and approximately 6,800 linear feet of 6-inch water main replacement using open cut and horizontal directional drilling. Santa Clara County, California issued two recent ITBs: the County Sanitation District No. 2-3 Structural Defect Repair Project Phase 2 (posted August 26, 2026, due September 17, 2026) requiring removal and replacement of vitrified clay pipe with PVC and HDPE at multiple diameters, service connection fittings including wyes, and mainline extensions with precast concrete manholes across thirty-five point repairs and five pipe-burst replacements; and the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard (posted April 29, 2026, due May 21, 2026), a broader roadway project that includes pavement and ADA improvements but does not specifically itemize mechanical connectors in the available scope summary. The Pinellas County opportunity applies a 10% Small Business Enterprise participation goal.
