TECHNICAL SPECIFICATIONS I SCOPE OF WORK PREVENTIVE MAINTENANCE & REPAIR SERVICES FOR BUS FIRE SUPPRESSION AND GAS DETECTION SYSTEMS CP B28049 A-1 TS1 Scope This specification and all related Contract Documents cover the service requirements for the complete maintenance and repair of the Authority's Amerex Fire Suppression and Gas Detection Systems. The Authority currently operates approximately 375 CNG (Compressed Natural Gas) buses with both systems on the buses, and approximately 160 diesel buses with only the Amerex Fire Suppression System. Each bus will require preventive maintenance services every six months for each of the systems. TS2 General Requirements TS 2.1 Preventive maintenance of the Amerex Fire Suppression and Gas Detection Systems shall be performed on the Authority's bus fleet in intervals of six (6) months. The Authority shall issue work orders for scheduled preventive maintenance and for unscheduled maintenance repairs by email through the Authority's Garage Management program. The Contractor's personnel shall notify the Garage General Superintendent or their designee of their arrival on to the Authority's property. The Contractor shall perform the required work on the issued work orders and sign the work orders upon completion. TS 2.2 The table in Exhibit "0", MARTA Fire Suppression and Gas Detection System Service Dates, shows the service dates for the fire suppression system cylinders and gas detection systems currently installed in MARTA buses. MARTA has an inventory of approximately 50 agent cylinders that are used to exchange with expired or about to expire installed cylinders. Thus, the list provided in Exhibit "0" will not be current at the time of contract award. The list is provided for information purposes only. The New Flyer and Orion buses have different cylinders. The New Flyer buses have a Horizontal Cylinder and the Orion buses have a Vertical Cylinder. Within fourteen (14) calendar days following the issuance of the Notice to Proceed, the Authority will email the Contractor a list of the Authority's bus fleet with the applicable fire suppression and gas detection systems and the most recent dates of inspection. The up-to-date list of installed cylinders will include the information provided in Exhibit "0", in addition to the bus numbers that each cylinder is installed in. The Authority will also provide the Contractor with a list of cylinders currently in inventory and their respective stamp/tag/hydrostatic dates. It is the Authority's intent for the Contractor to make an initial assessment and identify all fire suppression and gas detection systems with preventive maintenance exceeding the six-month preventive maintenance period at the onset of the contract period. Within five (5) business days following the receipt of the list, the Contractor shall identify all Page 1 of 6
