NOTE: The requirements will not be quoted on the base bus but will be a separate line item on the purchase document. Training materials and time cost should be included in the options with associated costs.

The Contractor shall have at least one qualified instructor who shall be available at the Agency’s property for [insert number] calendar days between the hours of [insert starting time] and [insert closing time] per month for [insert number] months prior to, and [insert number] months after, acceptance of the first bus. Instructor(s) shall conduct schools and advise the personnel of the Agency on the proper operation and maintenance of the equipment. The Contractor also shall provide visual and other teaching aids (such as manuals, slide presentations and literature) for use by the Agency’s own training staff and which become the property of the Agency.

NOTE: Agency to insert language that specifies the hours when it wants the training to occur, the total number of hours of instruction it wants to be provided, what items it expects the curriculum to cover and the format in which it expects the training and teaching aids to be provided (print, DVD, etc.).

Technical/Service representatives

The Contractor shall, at its own expense, have one or more competent technical service representatives available on request to assist the Agency in the solution of engineering or design problems within the scope of the specifications that may arise during the warranty period. This does not relieve the Contractor of responsibilities under the provisions of Section 7: Warranty Requirements.

4.7Operating environment

The bus shall achieve normal operation in ambient temperature ranges of 10ºF to 115ºF, at relative humidity between 5 percent and 100 percent, and at altitudes up to 3,000 feet above sea level. Degradation of performance due to atmospheric conditions shall be minimized at temperatures below 10°F, above 115°F or at altitudes above 3,000 feet. Altitude requirements above 3,000 feet will need separate discussions with the engine manufacturer to ensure that performance requirements are not compromised. Speed, gradability and acceleration performance requirements shall be met at, or corrected to, 77°F, 29.31 in. Hg, dry air per SAE J1995.


Interior noise

The combination of inner and outer panels and any material used between them shall provide sufficient sound insulation so that a sound source with a level of 80 dBA measured at the outside skin of the bus shall have a sound level of 65 dBA or less at any point inside the bus. These conditions shall prevail with all openings, including doors and windows, closed and with the engine and accessories switched off.

The bus-generated noise level experienced by a passenger at any seat location in the bus shall not exceed 80 dBA. The driver area shall not experience a noise level of more than 75 dBA.

An exception shall be made for the turntable area, which shall be considered a separate environment.

Exterior noise

Airborne noise generated by the bus and measured from either side shall not exceed 80 dBA under full power acceleration when operated 0 to 35 mph at curb weight. The maximum noise level generated by the bus pulling away from a stop at full power shall not exceed 83 dBA. The bus-generated noise at curb idle shall not exceed 65 dBA. If the noise contains an audible discrete frequency, a penalty of 5 dBA shall be added to the sound level measured. The contractor shall comply with the exterior noise requirements defined in local laws and ordinances identified by the procuring agency and SAE J366.

4.9Fire safety

The bus shall be designed and manufactured in accordance with all applicable fire safety and smoke emission regulations. These provisions shall include the use of fire-retardant/low-smoke materials, fire detection systems, bulkheads and facilitation of passenger evacuation.

All materials used in the construction of the passenger compartment of the bus shall be in accordance with the Recommended Fire Safety Practices defined in FMVSS 302, dated October 20, 1993. Materials entirely enclosed from the passenger compartment, such as insulation within the sidewalls and sub-floor, need not comply. In addition, smaller components and items, such as seat grab rails, switch knobs and small light lenses, shall be exempt from this requirement.

4.10Americans with Disabilities Act

The contractor shall comply with all applicable federal requirements defined in the Americans with Disabilities Act (ADA), 49 CFR Part 38, and all applicable state, provincial and local regulations.

4.11Respect for the environment

In the design and manufacture of the bus, the contractor shall make every effort to reduce the amount of potentially hazardous waste. In accordance with Section 6002 of the Resource Conservation and Recovery Act, the contractor shall use, whenever possible and allowed by the specifications, recycled materials in the manufacture of the bus.


IP 5.Physical size

With exceptions such as exterior mirrors, marker and signal lights, bumpers, fender skirts, washers, wipers, ad frames, cameras, object detection systems, bicycle racks, feelers and rub rails, the bus shall have the following overall dimensions as shown in Figure 1 at static conditions and design height.
