UNSPSC 30171607: Horizontal slider windows

UNSPSC 30171607 Horizontal slider windows, a Commodity code, covers the supply and installation of sliding window systems in state and local building projects, ranging from single-facility replacements to district-wide school renovations. Recent solicitations show counties, cities, school districts, and special-purpose authorities purchasing horizontal sliders as part of broader facility upgrades, security hardening, and energy-efficiency retrofits. Work includes removal of existing windows, installation of new aluminum or commercial-grade horizontal-sliding systems with low-E glass and insulating features, weatherproofing, and finishing work such as drywall repair and painting. Orange County, Florida has emerged as a repeat buyer, soliciting window replacement at the Fredrick Douglas Building (Y26-743, sealed IFB, estimated cost $319,428.00, bid due June 9, 2026) and separately procuring aluminum sign blanks through a five-year requirements contract (Y26-162). The City of Phoenix Housing Department issued a multi-family window replacement RFP (FY26-0861-13, due May 11, 2026) requiring commercial-grade aluminum systems with historic preservation compliance and Davis-Bacon prevailing wage requirements. Elk Rapids Schools (Michigan) posted a horizontal-slider window and shade replacement RFP (RFPELK2600000016301, mandatory pre-bid April 10, 2026, sealed bids due April 17, 2026, completion by August 19, 2026) specifying approved manufacturers including EFCO Corporation, Kawneer, Wausau, YKK, and Wojan.

Recent activity concentrates in Florida, Arizona, Michigan, Georgia, South Carolina, and Wisconsin. Issuing bodies include county purchasing departments (Portage County, Wisconsin; Orange County, Florida; Beaufort County, South Carolina), municipal housing and public works divisions (Phoenix Housing Department; Kissimmee Utility Authority), and school districts (Elk Rapids Schools; Burke County Public Schools, Georgia). Projects range from $13,000 to $319,428 on individual contracts, with typical requirements including Commercial General Liability insurance of $1,000,000 to $2,000,000, bid bonds of 5 to 10 percent, and performance or payment bonds. Evaluation emphasizes qualifications, experience on similar school or institutional projects within ten years, compliance with local building codes and OSHA, and fixed or firm pricing. Procurement mechanisms vary between sealed IFB, RFP, and RFQ formats, with electronic submission mandated in most recent Florida solicitations. Pre-bid meetings and site visits are common, with question deadlines typically 10 to 14 days before bid due dates.
