About NIGP 55923

NIGP 55923 Crossing Equipment And Accessories, Railroad (Including Crossing Signs), Item code, covers traffic control equipment, signage, and related infrastructure deployed by state departments of transportation, counties, cities, and transit authorities — but the recent opportunities block shows nearly zero activity under this code's literal scope. Instead, recent state and local solicitations reveal that what government bodies are actually buying under traffic and pedestrian safety infrastructure falls into adjacent categories: temporary traffic control services, permanent pavement markings, signal equipment and detection systems, speed-calming devices, pedestrian crossing improvements including Rectangular Rapid Flashing Beacons, and sign fabrication and installation for general-purpose directional, warning, and regulatory work. The issuing bodies span state DOTs (California, Pennsylvania, Utah, Missouri, Florida), cities and townships (Harrisburg, Cambridge, Watertown, Yuma, Langhorne, Port Carbon, Foster, East Union), counties (Harris, Collier, Allegheny), transit authorities (MBTA, Charlotte CATS, UDOT), and special-purpose districts. Repeat buyers include the California Department of Transportation (posting small-business-set-aside Minor B contracts for signage, detection, and infrastructure work at a sustained clip), PennDOT-administered projects across Pennsylvania municipalities, and Missouri DOT for proprietary traffic detection and message-sign equipment and parts under sole-source procurement.

Geographic concentration is heaviest in California (particularly the San Diego, San Joaquin, Stanislaus, Orange County, Kern, and Nevada County districts), Pennsylvania (through cooperative channels), Utah, and Missouri — with secondary activity scattered across Massachusetts, Texas, Florida, and Arizona. Representative recent opportunities include the Pennsylvania Tourism Signing Trust's Project 100-33 logo sign installation across six counties (sealed bids due October 15, 2026, via PennBID), the California Department of Transportation's multiple SB Minor B contracts for curve warning signs, signal detection replacement, and roadside rehabilitation (all email-bid, hard-cap $484,000, September–October 2026 windows), Collier County's Invitation for Qualifications for countywide signage design and installation (RFQ with pre-proposal conference October 15, 2026, two-year term with three one-year renewals), the Utah Department of Transportation's traffic control services procurement across three regions (IFB due October 16, 2026, dual-award structure), and the City of Harrisburg's line striping and pavement markings project (IFB due September 23, 2026, mandatory site visit, prevailing wage, $72.03/hour line-striping rate). Activity under the literal NIGP 55923 code — railroad crossing equipment and signs — is not evident in the recent opportunities; pursuit should focus instead on the adjacent, higher-volume categories where state and local government is actively spending.
