NIGP 28577: Square Duct and Fittings

NIGP 28577 Square Duct and Fittings, an Item code, encompasses ducting components and associated fittings that state and local governments procure as part of larger facility infrastructure, HVAC system maintenance, and mechanical equipment projects. Recent solicitations show that this code sits within broader electrical and mechanical equipment categories, with state and local buyers acquiring square duct and fittings alongside related parts and supplies for building systems, repairs, and ongoing operations. The code serves school districts, counties, and other public entities managing facilities infrastructure and equipment replacement cycles.

Northside Independent School District in San Antonio, Texas posted IFB 2026098 on June 8, 2026, seeking electrical equipment, parts, supplies, rentals, repairs, and services with a response deadline of July 1, 2026—a replacement for an expiring contract that required all incumbent and prospective vendors to respond or lose future business. Sourcewell, a Minnesota cooperative purchasing vehicle operating under RCW 39.34, issued RFP 061626 on May 12, 2026, for law enforcement equipment, with a June 16, 2026 deadline, structured to serve thousands of governmental agencies, school districts, and public entities across the United States and Canada, though that opportunity focuses on equipment outside the square-duct scope. Activity under this code appears limited in the recent state and local opportunity set, with the Northside IFB representing the most directly relevant recent solicitation for mechanical and electrical components in the code family.
