NIGP 05589: Warning Devices, Triangular (Including Slow Moving Vehicle Signs)

NIGP 05589 Warning Devices, Triangular (Including Slow Moving Vehicle Signs), an Item code, covers sign blanks, fabrication, installation, and traffic infrastructure that state and local governments buy to support roadway safety, facility identification, and regulatory compliance. Recent solicitations show counties purchasing aluminum sign blanks on indefinite-quantity, as-needed arrangements; prefabricated traffic signposts meeting FDOT specifications; and design-through-disposal services for comprehensive signage programs spanning directional, safety, regulatory, ADA-compliant, and electronic message signs. Issuing bodies are predominantly county governments, including Collier County, Pasco County, and Hillsborough County in Florida, and Williamson County in Texas. Work scopes range from one-time equipment purchases to multi-year, pre-qualified contractor pools supporting project-by-project competitive bidding, with contractors required to hold state specialty licenses, carry comprehensive liability insurance naming the county as additional insured, and comply with E-Verify and local-vendor-preference criteria when applicable.

Recent activity concentrates in Florida, where Collier County posted an Invitation for Qualifications (IFQ) due November 6, 2026, for a two-year signage services contract with three optional one-year renewals, emphasizing firm experience (45 points), specialized team expertise (35 points), and local-contractor preference (10 points); Pasco County issued an as-needed RFQ for aluminum sign blanks due October 13, 2026; and Hillsborough County conducted competitive sealed bidding (ITB 26-00258) for traffic signposts at $103,776 estimated value due May 29, 2026, with delivery to Tampa within 20 days of purchase order. Insurance minimums and compliance documentation are standard across these procurements, with Woman and Minority Business Enterprise certification scoring available where claimed. The code sees intermittent activity tied to infrastructure maintenance and facility-upgrade cycles rather than continuous demand.
