Approved or Approved Type (signifying Approval): design, type of material, procedure, or method given written acceptance by TTC. Baseline Design Configuration: the design configuration Approved by TTC at the First Article Inspection of the Pilot Bus and defines the configuration of the serial production Buses. Coach (also bus): a complete vehicle that conforms to this Scope of Work and is ready to operate. Engineering Drawings: a formal engineering document, fully dimensioned with tolerances, materials specifications, etc. that adequately defines a part for manufacture and assembly. Engineering Drawings must berevision controlled and formally approved by appropriate Contractor staff. Equal: whenever the words “equal,” “equivalent,” or “approved equal” are used in connection with make or quality of material or equipment, the proposed alternative shall be functionally compatible with and of equal or better quality than the item it is proposed to replace. The Contractor must provide, for TTC approval, appropriate technical documentation to verify equivalence, including a dimensioned drawing, detailed material specifications and testing documentation. The TTC Project Manager’s decision as to whether any material or equipment proposed is equal to that specified shall be binding and final. Fire Retardant Materials: materials that have a flame-spread index less than 35, as measured in a radiant panel flame test per ASTM-E-162-90. Fireproof Materials: materials that will not burn or melt at temperatures less than 2,000 degrees Fahrenheit (2,000°F) or (1,093°C). Fire-Resistant Materials: materials that have a flame spread index less than 150, as measured in a radiant panel flame test per ASTM-E 162-90.

First Article Inspection (FAI): the physical examination, functional and commercial testing and acceptance/approval by TTC or a designated representative of TTC, of an initial part, major assembly, subassembly, system, subsystem, apparatus or material, manufactured or assembled by either the Contractor or Subcontractors. The FAI shall also include a maintainability and quality review of the component/system. Hardware: includes but is not limited to nuts, bolts, screws, rivets, fittings, clamps, washers, lock washers, etc.

Hose: the term “hose” shall be interpreted as any flexible vessel used to transport lubricant, coolant, fuel, compressed air, or any other fluid from one part of the vehicle to another. This shall be interpreted as including all flexible “lines” and “tubes,” regardless of material (rubber, plastic, braided steel, etc.). Pipes, which are hard plumbed, are not included in this definition (See also “Pipe”). Latch: when used, the term “latch” shall include the latch itself, the latch striker (if applicable), and all hardware used to secure the latch and striker. Line: see Hose. Lock-out Tag: refers specifically to procedures used to ensure that equipment is shut down and inoperable until maintenance or repair work is completed. The “Lock-out Tag” are used to keep staff safe from equipment or machinery that could injure or kill them if not managed correctly (i.e. high voltage electrical systems of a diesel-hybrid bus). Maintenance Manual(s): detailed instructions for servicing and maintaining the bus, electrical prints, pneumatic diagrams, and hydraulic diagrams. Mean Distance Between Failures (MDBF): the mean operating distance (measured in kilometers) between independent failures resulting in a bus being removed from service. New System: any system that is specified to be incorporated into TTC’s NOVA bus fleet, as outlined in this Scope of Work which was not incorporated in the buses when they arrived at the Contractor’s facility.

Optional Contract Award: refers to TTC’s decision to award a Contractor with up to 22 additional buses in a given year, for which the Scope of Work is to be completed. Overhauled: remanufactured/rebuilt in accordance with an approved procedure as outlined in the Scope of Work. If not specifically stated, all equipment requiring overhaul shall be performed in accordance with approved original OEM or supplier specifications. Pipe: any rigid tubing, piping, or ducting which is hard plumbed in place shall be considered “pipe” and is not to be confused with hose, tube, etc. Examples of pipe are copper tubing, and exhaust ducting or piping. Proof (used as a suffix): apparatus is designated as “splash proof,” “dustproof,” etc., when so constructed, protected, or treated that its successful operation is not interfered with when subjected to the specified material or condition. Rebuild: to restore an item to OEM specifications by replacing all wear items of a component including cleaning, adjusting, lubricating and painting according to the OEM’s recommendations and specifications using OEM parts.

Remanufactured: overhauled/rebuilt in accordance with an approved procedure as outlined in the Scope of Work. If not specifically stated, all equipment requiring overhaul shall be performed in accordance with approved original OEM specifications. Replace: To replace in kind with new components unless otherwise specified. Safe: the condition in which passengers, operators, or maintenance personnel are secure from threat or danger, harm, or loss arising from improper design, manufacture, assembly, malfunction, or failure of the bus or any ofits components or systems.

Service Proven: refers to the design of any component, system, or subsystem that has a proven history of at least 30,000 kilometers on a single bus of successful operation in revenue service in Canada or the Northeastern United States. Proof of successful operation shall be substantiated by submission of reliability/failure data, service time and location, modification information, maintenance records, and references as required by the Contract Documents.

Standards: standards referenced are the latest revisions unless otherwise stated. Self-Extinguishing: materials in which flame propagation is limited to 4.0 inches when tested in accordance with Federal Motor Vehicle Safety Standards. Special Listings: technical Documentation regarding the Operation and Maintenance of a bus or the bus’s subcomponents which is not provided as part of the OEM or OEM vendor Maintenance and Parts Manuals.
