B. The contract will be for a one-year period from the date of award, with four (4) one-year options. Exercise of the option years shall be at the sole discretion of a U.S. Government Contracting Officer.

QUALITY ASSURANCE AND SURVEILLANCE PLAN (QASP)

This plan provides an effective method to promote satisfactory contractor performance. The QASP provides a method for the Contracting Officer's Representative (COR) to monitor Contractor performance, advise the Contractor of unsatisfactory performance, and notify the Contracting Officer of continued unsatisfactory performance. The Contractor, not the Government, is responsible for management and quality control to meet the terms of the contract. The role of the Government is to monitor quality to ensure that contract standards are achieved.

1. SURVEILLANCE. The COR will receive and document all complaints from Government personnel regarding the services provided. If appropriate, the COR will send the complaints to the Contractor for corrective action.

2. STANDARD. The performance standard is that the Government receives no more than one (1) customer complaint per year. The COR shall notify the Contracting Officer of the complaints so that the Contracting Officer may take appropriate action to enforce the inspection clause (FAR 52.212.4, Contract Terms and Conditions - Commercial Products and Commercial Services (NOV 2023), if any of the services exceed the standard.

MINIMUM AND MAXIMUM AMOUNTS

During this contract period, the Government shall place a minimum of one semi-annual preventive maintenance and inspection service request for a standby, low voltage diesel generator.

1. GENERAL INFORMATION

The United States Embassy in Conakry requires professional services and contractor cost proposals to perform Planned Maintenance and Inspection services of the facility's Low Voltage Diesel Standby Generator systems.

1.1 CONTRACT SCOPE AND LIMITATIONS

A. Standby Service - Standard Application This contract is designed for diesel standby generators in emergency/standby service. The standard maintenance schedule assumes:

· Infrequent operation (emergency use and regular testing only)

· Typical annual operating hours are less than 200 hours

· Calendar-based maintenance intervals (two visits per year) B. Prime Power and High-Utilization Applications While the maintenance tasks in this SOW are applicable to prime power and continuous duty operations, the service visit frequency and scheduling must be modified for these applications.

Posts operating generators in the following modes must notify the Contracting Officer prior to solicitation to adjust service intervals and pricing:

· Prime power or continuous duty operations

· Peak shaving or co-generation systems

· High-frequency operation (>200 hours annually)

· Extended run-time operations For these applications:

· Maintenance intervals shall follow manufacturer's hour-based schedules rather than calendar-based

· Service visit frequency shall be increased (typically quarterly or more frequently)

· Additional monitoring and testing requirements may apply

· Pricing structure must account for increased service frequency and consumables usage C. Service Visit Frequency - Standby Service For standard standby service, this contract provides TWO (2) scheduled maintenance visits per year:

· One (1) Semi-Annual service (every 6 months ±30 days)

· One (1) Annual service (every 12 months ±30 days) Additional visits, major repairs, or component replacements require separate purchase orders.

D. Hour-Based Maintenance Triggers Certain manufacturer-required maintenance is triggered by operating hours regardless of calendar intervals (e.g., valve lash adjustment, oil changes, major services).

The Contractor shall:

· Record operating hours at each service visit

· Notify the COR when generators approach hour-based maintenance intervals

· Follow the more frequent calendar-based or hour-based schedules per manufacturer’s recommendations

· Perform hour-based maintenance at the next scheduled visit if within acceptable range, or coordinate additional service if immediate attention is required

2. PROJECT REQUIREMENTS

8. Engine Control Module (ECM)

· Plug in OEM computer/diagnostic hardware.

· Review fault history

· Download status report or similar depending on manufacturer to be submitted with report

9. Run Unit – No Load

· Run the generator with no load for 10 minutes

· Remote Start Panel - Inspect and test operation

· Check the generator for unusual conditions, such as: excessive vibration, leaks, smoke

· Verify all meters, gauges and indicators are normal and functioning properly

10. Run Unit – With Load Start unit and run under load for minimum 2 hours at 75-80% of rated capacity:

· Unit should be run under facility load if COR authorizes to test and exercise entire system

· If facility load is not permissible or is not a minimum of 50% of rated capacity, the unit shall be exercised with a load bank to a minimum 75-80% capacity for 2 hours

NOTES:

· The only way to ensure your system functions and is available in the event of an outage is to perform a real load test with the facility

· Continual low or no-load running results in low pressures in the engine cylinders which do not allow the piston rings to seat resulting in oil entering the combustion chamber and exhaust tract. This is commonly referred to as "wet stacking" and can cause reduced capacity, equipment damage and premature failure

· Loading of the generator will ensure proper performance of cooling and ventilation systems and that unit can run for extended periods under load without overheating

· Performing a load bank test in addition to the facility load will also exercise and verify operation of post load bank During Load Test:

· Automatic Start/Stop – Inspect

· Check louvers, shutters and room exhaust fans for proper operation

· Generator Set Vibration – Inspect

· Read and record all key performance indicators from gauges/meters/ECM:

· Ambient Temperature

· Coolant Temperature

· Oil Pressure

· DC Voltage

· Frequency (HZ)

· Amps (A/B/C phases)

· Volts (AB/BC/CA)

· Volts Phase-Neutral (A/B/C)

· Power Factor (PF)

· KW output

· % of Capacity

· Fuel Consumption at this load

· Record Alternator bearing temperatures

· Check exhaust for excessive black or white smoke

· Check turbocharger for vibrations or any abnormal noise during operation

· Check generator bearing for noise and overheating
