Recent solicitations show state and local buyers using blanket purchase orders, indefinite-quantity unit-price contracts with multi-year terms, and standing supply arrangements to manage fleet maintenance across diverse bus models. Issuing bodies include state corrections departments with captive bus fleets, municipal transit authorities, and city departments of transportation operating fixed-route and commuter coach services.
