OEM

The contractor shall provide two (2) class slots at the manufacturer’s suppliers' training facility for a “train-the-trainer” technical instruction course on the operation, diagnostics, troubleshooting, repair, and servicing of the below listed areas:

1. Engine

2. Transmission

3. Data Communication System

4. Hybrid Drive

5. Fare Collection device.

6. Electric Drive Each Purchaser will only be allowed to select two (2) of the six (6) training areas to send their two (2) representatives. This represents the OEM base requirement.

The Purchaser’s training department shall coordinate the scheduling of training with the contractor. Each training subject area (module), to include manufacturer’s supplier training facility slots, shall also be priced separately from the bus in the Price Sheet.

Operating Environment The bus shall be capable of satisfying the requirements of this specification while operating in ambient temperature ranges of 10 to 115 °F, at relative humidity between 5% and 100%, and at altitudes up to 3000 ft 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 3000 ft. Altitude requirements above 3000 ft will need separate discussions with the propulsion/drive system manufacturer to ensure that performance requirements are not compromised. Speed, gradeability, and acceleration performance requirements shall be met at, or corrected to, 77°F, 29.31 inHg, dry air per SAE J1995.

Purchasers may define operating environments differently from the description.

Secure Lines, Hoses, and Wiring All lines, hoses, wiring, and similar connective materials shall be tied and secured so as not to interfere with the operation of the vehicle or any component system. At a minimum, electrical wiring shall be insulated. All wiring looms and all wiring harnesses shall be wrapped in weather-resistant tubing or wrap material in accordance with applicable local, state, and federal regulations. All lines, hoses, and wiring shall be positioned and configured so as to prevent chafing and cutting.

NOISE

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 68 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. Maximum internal noise level shall not exceed 75 dBA in the operator’s area near normal operator ear level and 80 dBA in all other areas in the interior of the vehicles under all normal operating conditions at locations inside the bus in adherence with the standards of ISO 5128. Articulated buses shall be exempted from this requirement 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. All noise readings shall be taken fifty (50) feet from, and perpendicular to, the centerline of the bus with all accessories operating. The Contractor shall comply with the exterior noise requirements defined in local laws and ordinances identified by the Purchaser and SAE J366.

Fire 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 and FTA Docket 90, 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.

Fire Suppression CNG-propelled buses shall have a methane gas detection system as an option and priced as a separate line item. A fire suppression system shall be installed per the manufacturer’s recommendation. Other fire suppression systems may be available as options (Fog Master or similar product).

The fire suppression system shall meet the minimum life cycle of the bus bid. Cylinders should be heavy-duty type that can be hydro tested and recertified 12 years after the manufacture date. Cylinders offered must come from new stock that will not affect the life cycle of the bus. Fire suppression manufacturer must provide Training on inspections and service as part of the purchase price. Bus OEM shall offer actuators, sensors, and other key parts of the suppression system that will need to be replaced during the life of the bus, on the spare parts list.

Materials Respect 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.

DIMENSIONS

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.

FIGURE 1:

Bus Length For ease of use, the following tolerances will be allowable for each given bus length. Bus length is determined as the measurement from bumper to bumper.

Bus Width Body width shall not exceed 102 in. (+0, -2 in.).

NOTE TO USER: Body width measurements are without mirrors.

Bus Height Maximum overall height shall be 150 in., including all rigid, roof-mounted items such as A/C, exhaust, fuel system, and cover, etc.

Step Height The step height shall not exceed 16.5 in. (+.5, -.5 in.) at either doorway without kneeling and shall not exceed 15.5 in. at the step. A maximum of two steps is allowed to accommodate a raised aisle floor in the rear of the bus.

Underbody Clearance The bus shall maintain the minimum clearance dimensions as shown in Figure 2 and defined in SAE Standard J689, regardless of load up to the gross vehicle weight rating.

Ramp Clearances The approach angle is the angle measured between a line tangent to the front tire static loaded radius arc and the initial point of structural interference forward of the front tire to the ground.

The departure angle is the angle measured between a line tangent to the rear tire static loaded radius arc and the initial point of structural interference rearward of the rear tire to the ground.

The breakover angle is the angle measured between two lines tangent to the front and rear tire static loaded radius and intersecting at a point on the underside of the vehicle that defines the largest ramp over which the vehicle can roll.

TABLE 2

Ground Clearance Ground clearance shall be no less than 9 in. (8 in. at jacking pad) except within the axle zone and wheel area. Axle zone clearance, which is the projected area between tires and wheels on the same axial centerline, shall be no less than 5.4 in.

Wheel area clearance shall be no less than 8 in. for parts fixed to the bus body and 6 in.
