NIGP 28024: Building Cables and Wires, Single and Multiconductor: Types Nm, Thwn, Tw, Thw, Thhn, Xhhw, Rhw, Rr, Romex, etc.

NIGP Item 28024, Building Cables and Wires (Single and Multiconductor: Types NM, THWN, TW, THW, THHN, XHHW, RHW, RR, Romex, etc.), covers the supply of insulated electrical conductors and jacketed wire assemblies that state and local governments procure for facility electrical infrastructure, equipment installations, and maintenance work. Recent solicitations show purchasing across correctional facilities, municipal utilities, school districts, state transportation departments, water management districts, and housing authorities, with a mix of routine restock purchases, project-specific material needs, and long-term supply contracts. The code spans straightforward material procurement (rolls of THHN wire, conductors, cable connectors) through to integrated supply arrangements with annual or multi-year contract terms.

Activity across the code concentrates in California, Georgia, Texas, and Florida, with additional recent opportunities in Maryland, Mississippi, and Utah. Representative recent work includes the California Department of Corrections and Rehabilitation soliciting jacketed wire and cable connectors for Mule Creek State Prison under IFB FPCM-MCSP-I001145-M001-KR-C (bids due October 28, 2026), Caltrans requesting aluminum conductors across multiple Central Valley jurisdictions under IFB HSR26-39 (due November 19, 2026), Gainesville Regional Utilities procuring a three-year wire and cable supply contract under RFP 2026-067 (proposals closed), and the Texas Department of Transportation Amarillo District issuing IFB No. 601340000065445 for XHHW and bare copper stranded wire (submission closed May 8, 2026). The Florida Department of Corrections issued a multi-zone statewide electrical services and repair contract (ITB-26-088, public bid opening August 25, 2026) that implicitly requires conductor and cable materials. Set-asides and preferences appear regularly: California-certified small business preferences (5%), MBE goals (15% at Maryland Environmental Service), DVBE incentives, and local vendor preferences shape several procurements. Lead times and supply chain stability matter—utilities and school districts prioritize on-time delivery and stock availability, often with 60- to 90-day delivery windows and multi-year renewal options to reduce procurement friction.
