<strong>Standard</strong> <strong>Bus</strong> <strong>Procurement</strong> <strong>Guidelines</strong><br />
The bus shall be designed to operate in transit service for at least 12 years or 500,000 miles. It shall be<br />
capable of operating at least 40,000 miles per year including the twelfth year.<br />
5.1.5.4.2 Maintenance and Inspection<br />
Scheduled maintenance or inspection tasks as specified by the Contractor shall require a skill level of<br />
3M or less. Scheduled maintenance tasks shall be related and shall be grouped in maximum mileage<br />
intervals. Base upon the Design Operating Profile defined in Section 5.1.2, routine scheduled<br />
maintenance actions, such as filter replacement and adjustments, shall not be required at intervals of less<br />
than 6,000 miles, except for engine oil/filter change intervals for severe duty shown below and routine<br />
daily service performed during the fueling operations. Higher levels of scheduled maintenance tasks<br />
shall occur at even multiples of mileage for lower level tasks. The Contractor may require routine<br />
scheduled maintenance actions at shorter intervals when a more severe operating profile is anticipated.<br />

All systems or <strong>com</strong>ponents subject to periodic maintenance or that are subject to periodic failures shall<br />
be readily accessible for service and inspection. To the extent practicable, removal or physical<br />
movement of <strong>com</strong>ponents unrelated to the specific maintenance and/or repair tasks involved shall be<br />
unnecessary.<br />
As a goal, relative accessibility of <strong>com</strong>ponents, measured in time required to gain access, shall be<br />
inversely proportional to frequency of maintenance and repair of the <strong>com</strong>ponents. Specific<br />
maintainability requirements are defined in other sections of Part 5: Technical Specifications.<br />
5.1.5.4.4 Interchangeability<br />
Components with identical functions shall be interchangeable to the extent practicable. These<br />
<strong>com</strong>ponents shall include passenger window hardware, interior trim, lamps, lamp lenses, and seat<br />
assemblies. Components with nonidentical functions shall not be, or appear to be, interchangeable.<br />
Any one <strong>com</strong>ponent or unit used in the construction of these buses shall be an exact duplicate in design,<br />
manufacture, and assembly for each bus in this Contract.<br />
