About NIGP 556
NIGP 556 Mass Transportation, Transit Bus, a Class code, encompasses design, supply, installation, integration, maintenance, and operation of onboard bus surveillance systems; fixed-route vehicle and operator scheduling software; bus shelter manufacturing; transit bus destination signage; charter and paratransit transportation services; vehicle inspection and compliance auditing; and facility operations including control centers, video mirror solutions, and scheduling dispatch systems—grounded in active state and local solicitations across multiple transportation modes and operational scopes.
State departments, counties, cities, transit authorities, and special-purpose transportation districts solicit under this code, with notable repeat activity from Florida jurisdictions (Broward County Transportation, Escambia County Area Transit, Pinellas County Solid Waste, Sarasota County Transit, Orange County) and California agencies (City of Santa Monica Department of Transportation, Orange County Transportation Authority, Stockton Unified School District). Recent opportunities span onboard bus video surveillance system design and integration (City of Santa Monica, RFP 491, due November 5, 2026); charter transportation services for educational tours and field trips (Pinellas County Solid Waste, ITQ 260749, due October 6, 2026; Stockton Unified School District, RFP 2615, due June 1, 2026); prefabricated bus shelter manufacturing under federal disaster recovery funding (Escambia County for ECAT, IFB PD2526110, due September 30, 2026); fixed-route operations and maintenance covering 219 buses across two facilities (City of Phoenix, RFP PTD26004, due September 30, 2026); paratransit operations management and scheduling (Orange County Transportation Authority, RFP 260, due November 5, 2026); and vehicle and operator scheduling software procurement (City of Santa Monica, RFP 471, due June 10, 2026). Geographic concentration appears strongest in Florida and California, with secondary activity in Texas, Oregon, Wisconsin, Illinois, Georgia, Kentucky, and Michigan. Activity is current and active, with procurement timelines extending through late 2026 and into 2027, driven by federal Transit Administration funding, disaster recovery CDBG-DR allocations, and operational modernization initiatives across urban and regional transit systems.
