Generator Maintenance and Service Records Assessment Contract

SCOPE OF WORK Complete an initial assessment of all generators and establish maintenance and service records to include schedules per generator based on guidelines outlined in this scope of work and in adherence with specific equipment manufacturer specifications. Submit service and repair records to NYCHA Administration upon completion of work and as requested.

Provide quarterly schedule for all maintenance per generator. This schedule must be submitted prior to the next quarter and approved by a NYCHA Administrator. Minor Preventative Maintenance: For each Generator, perform four (4) Minor Preventative Maintenance visits annually, once per quarter.

Each Minor Preventative Maintenance visit shall take place within seventy-five (75) to ninety-one (91) days after the last Minor Preventative Maintenance visit. Please note the 4 th quarterly inspection will be incorporated into the one annual service visit. All work shall follow specific equipment s recommended maintenance and service guidelines. Vendor shall supply all necessary tools, parts, and materials.

During each Minor Preventative Maintenance visit on each Generator, the Vendor shall perform typical generator maintenance in accordance with the O&M manual and with industry best practice, including but not limited to the following tasks: Cooling Systems: Visual inspection of radiator or heat exchanger for leaks, damage, and obstruction. Check jacket water coolant level and take coolant sample for analysis.

Test coolant for proper antifreeze percentage. Check jacket water heater for proper operation and adjust thermostat setting as needed. Inspect condition of radiator cap, gasket and sealing surface. Visual inspection of water pump and cooling system gaskets for leaks. Check belt tension and inspect for cracking and fraying if accessibility without disassembly permits.

Inspect pulleys for excessive wear and lubricate hub bearings as needed. Inspect flexible water connections for cracking, leaks, and pliability. Tighten hose clamps as needed. Lubrication System . Check and top off oil level. Check for excessive crankcase blow-by with engine running. Visual inspection of front and rear crankshaft seals and lubrication system gaskets for leaks.

Inspect oil hose and connections for cracking, leaks, and pliability. Take crankcase oil sample ; t esting should be as per manufacturer s guidance by submitting sample to a qualified testing laboratory or using the Engine Manufacturers Supplied Test kit. Consolidate the results of all Generator oil samples on a quarterly basis in spread sheet form detailing findings.

Inspect Fuel System Inspect gas pressure regulator and check for leaks. Drain water from water separator if applicable. Check gas line , Maxon valves and regulators for leaks. Check electronic governor connections and actuator. Inspect gas lines , Maxon valves and regulators for cracks, leaks, and proper line bracket support. Starting System Top off electrolyte level in batteries with dis tilled water.

Check and record battery charger/alternator for proper charge rate. Check for proper cranking te rm ination upon starting. Clean and apply corrosion inhibitor to the terminals of lead acid batteries as needed. Tighten battery cable connections as needed. Inspect and tighten starter motor, connections, and wiring.

Check and record battery voltage dip level during over crank t est for minimum voltage required to maintain controls during start-up. Exhaust System Inspect flexible exhaust coupling for cracks, excessive leakage, broken, or missing hardware. Inspect exterior of exhaust manifolds for oil/fuel slobbering (signs of wet stacking). Inspect exhaust rain protection and exhaust outlet screening.

Drain water in exhaust moisture traps. Air Intake System Inspect air filters for plugging and deterioration, clean if required. Check all air intake piping for damage and loose connections. Inspect air cleaner seal for pliability and sealing and clean if necessary. Inspect turbocharger for excessive endplay clearance (if accessible) and seal leakage. Walk around inspection of complete Generator installation.

Inspect Generator set vibration isolators. Check for abnormal noise or vibration. Re-check for oil and coolant leaks with engine running. Check for proper operation of remote fan motors, thermostats, circulating pumps, and solenoid valves. Check inlet and discharge louvers for proper operation with engine running and stopped. Control Panel Operational check of illumination and safety lamps.

Check electronic control panels for fault codes. Clear any unnecessary codes, notify customer of any codes that need to be addressed. Check proper operation of engine and generator instruments with generator running. Adjust governor control for optimum performance and frequency. Adjust voltage regulator for proper voltage. Check for and tighten loose terminals on the generator and the Generator control panel.

Check tightness of relays in the generator control panel. Inspect for excessive dirt accumulation and clean as needed. Test auto-start system. Test safeties and pre-alarms on engine/generator control and annunciator panels. Check operation of automatic sync equipment with customer authorization. Place generator online and check operation of transfer switches.

This will be done only with the consent of the Technical Resources Department. Upon Completion of Service reset all controls to automatic. Set circuit breaker to correct position. Check that gas valves are in correct position. Check that battery charger is on. Check that louver controls are on. Check that jacket water heater is on.

Provide an electronic checklist confirming all items were completed along with recording any measurements, descriptions of conditions, run times, and any notes. The checklist should also include the name of the service technician and date. Gas Booster Pumps, Control Panels and Maxon Valves Check operations. Service. Repair and replace. Fire Safety Equipment Inspection and maintenance of gas Co2 detection systems.

QEL Gas Monitoring System and detection devices and calibration, when necessary, as per manufacturers specifications in accordance with NFPA 12 and 1 RCNY 908-01 Chapter 900. Ventilation Systems Inspect, maintain, repair, and/or replace components of generator room ventilation systems.

Electric and/or gas heaters Inspect, service, maintain and repair electric and/or gas heaters within the generator room and/or Generator Enclosure, Gas Booster rooms, Electric Automatic Transfer Switch (ATS) rooms. l. Uninterrupted Power Source (UPS) i Check operation, service and repair/replace as needed. m. Automatic Transfer Switches i. Inspect and check operation. ii. Repair and/or replace as needed.
