Quick Summary
The General Services Administration (GSA) is conducting its 2026 Spring Open Season for the Main Bus Program. This opportunity allows existing contractors to submit new model year (NMY) updates for awarded line items and for current or prospective offerors to propose new bus models for consideration. The program procures a variety of passenger motor vehicles, including Adult Work Buses, School Buses, Shuttles, Inter-City Commuter Coaches, and Over-the-Road Touring Coaches. The bid period closes on March 20, 2026, at 12:00 PM Eastern Time.
Scope of Work
The Main Bus Program seeks vehicles that comply with Federal Vehicle Standard 833T. The Open Season process facilitates continuous updates to the program's offerings. Notably, the Transit Bus Program is scheduled to sunset in December 2026, and incumbent vendors are encouraged to onboard to the Main Bus Program. Deliverables for awarded contracts typically include weekly and monthly status reports, notifications for shipment delays, defects/recalls, and damage in transit updates.
