State of California - Bid Specification Zero Emission Buses 3600-0000032479 2310-0279652

SCOPE

This specification establishes the minimum requirements for zero emission buses (ZEBs) of both battery electric buses (BEBs) and fuel cell electric buses (FCEBs). This specification is not intended to dictate any specific design, but rather indicate the base type of bus and equipment desired by the State. This specification defines requirements for a base, medium-duty ZEB to be used for both suburban express service and general service on urban arterial streets. Specific options not included in this specification for the base ZEB shall be configured directly with the manufacturer and/or dealer.

The State of California, Department of General Services (DGS) in collaboration with the transportation districts within the State, seek to establish agreement(s) for the purchase of the most modern transit ZEBs available. Intent is to maximize passenger appeal in appearance, comfort, and safety, combined with excellence in reliability, operating characteristics, and economy of operation. The ZEBs are for seating ambulatory and wheelchair passengers from a wide spectrum of passengers including children, adults, elderly, and people with disabilities.

The contractor shall ensure that the application and installation of major subcomponents and systems are compliant with all such subcomponent vendors’ requirements and recommendations. Components used in the vehicle shall be of quality design and capable of transit service.

The ZEBs may be referenced as “the bus” or “the van” for this specification and requirements.
