PERFORMANCE WORK STATEMENT (PWS)

Preventative Maintenance Services for High-Volume Low-Speed (HVLS) Fans

1.0 INTRODUCTION AND BACKGROUND

This Performance Work Statement (PWS) outlines the requirements for preventative maintenance (PM) services for High-Volume Low-Speed (HVLS) fans located within the 128th Aviation Brigade’s operational footprint at Ft. Eustis, Va. 128th Aviation Brigade, hereafter referred to as "the Government," requires these services to ensure the continued failure, and extend the operational lifespan of the equipment. The Contractor shall provide

Government-Furnished), materials, and transportation to perform the PM services as

2.0 SCOPE OF WORK

The Contractor shall perform scheduled preventative maintenance on all HVLS fans ide ts included at the end of this PWS performed on each fan one time during the contract period of performance.

maintenance schedule with the 128th Aviation Brigade Facilities Managers, Brian Rounion,

- -4902, prior to performing any maintenance.

Performance includes provi Preventive Maintenance included recommended manufacturer 21-point inspection:

1. Clean all airfoils

2. Check tightness of all hardware with a torque wrench

6. Verify airfoil retainer clips are installed

8. Check mounting method

9. Check fan for plumb and level

10. Check torque of Fenner at 167 ft-lbs, if applicable

11. Check dimensions of any supplemental steel supports

12. Visually inspect welds

13. Check wiring methods used

14. Verify raceways are isolated (line, load, other fans)

15. Verify all electrical connections on motor and controller are correct arrangement and properly tightened

16. Verify fault history

17. Verify properly sized fuses are installed in controller, if applicable

18. Verify maximum HZ has not been changed in the VFD

19. Inspect for any signs of physical damage to fan or controller

20. Clear debris and dirt from the VFD with air gun

21. Document any customer complaints

If PM determines repairs are required, then PM contacts BAF to obtain a service quote and provides the quote to the organization POC. PM will include, or ensure BAF provides to the organization POC a report on completed services (e.g., Building number, type of fan, fan serial number, findings or needed repairs and/or recommendations).

2.1 Exclusions

This PWS covers preventative maintenance only.

• Repair work required due to incorrect fan mounting by others, damaged parts discovered during maintenance (e.g., cracked airfoils, worn bearings), or other operational failures is excluded from the scope of this contract.

3.0 APPLICABLE DOCUMENTS AND STANDARDS

The Contractor shall perform all work in accordance with:

Occupational Safety and Health Administration (OSHA) regulations, particularly

(LOTO), and working at heights.

4.0 SPECIFIC TASKS – PREVENTATIVE MAINTENANCE

The Contractor shall perform the following preventative maintenance tasks for each HVLS fan covered under this contract during each scheduled service visit:

4.1.1 Safely access the fan using an OSHA-approved, two-man scissor lift appropriate for reaching the fans safely.

for heavy equipment or training devices (aircraft) located near the fan installation area are

4.1.3 Adhere to all site-

4.2 Mechanical Inspection & Servicing:

4.2.3 Check the tightness of all accessible mounting hardware (hub-to-motor, airfoil-to-hub, mount-to-structure) using a calibrated torque wrench set to manufacturer's specified torque values. Record torque values checked/achieved.

4.2.4 Inspect the fan mounting method for secureness, integrity, and ensure the fan assembly is plumb and level according to manufacturer tolerances.

4.2.5 Inspect the entire fan assembly (motor, hub, airfoils, mount) for signs of corrosion, discoloration, pitting, or flaking of metal finishes.

4.2.6 Check breather cap for cleanliness and proper function (if applicable).

4.2.7 Check gearbox oil levels (if applicable). Inspect gearbox and motor for any signs of oil leakage. [Specify if oil sampling/analysis or oil changes at certain intervals are required, or if topping off oil is included. If oil change is required, specify type of oil and disposal requirements].

4.2.8 Inspect primary safety cable(s) (connections, condition, tension). If guy wires are present, check their tightness and anchor points for integrity.

4.2.9 Check the dimensions and integrity of any supplemental steel supports used for mounting the fan.

4.2.1 O Visually inspect accessible structural welds on the fan mount and any supplemental steel for signs of cracking or fatigue.

4.3 Electrical Inspection & Servicing:

4.3.1 Check wiring methods for proper installation, support, and protection (e.g., conduit, connectors, strain relief).

4.3.2 Verify electrical raceways are properly isolated (e.g., separating line voltage, control voltage, communication lines) according to manufacturer specifications and applicable codes.

4.3.3 Verify electrical connections on the fan motor and Variable Frequency Drive (VFD)/controller are secure and properly tightened according to manufacturer specifications.

4.3.4 Check and record any fault history stored in the VFD/controller. Clear faults after recording if appropriate and per manufacturer guidance.

4.3.5 Verify properly sized fuses are installed in the controller (if applicable).

4.3.6 Verify the maximum Hertz (Hz) setting has not been changed from the originally commissioned setting in the VFD parameters, unless directed otherwise by Government personnel and documented. Record current setting.

4.3.7 Inspect fan motor and controller enclosures for any signs of physical damage, water ingress, or overheating.

4.3.8 Clear accumulated dust and debris from the VFD/controller heatsinks and internal components using low-pressure, dry compressed air or an appropriate vacuum.

4.4 Documentation & Reporting During Service:

4.4.1 Document any non-repair related customer complaints or operational concerns reported by facility staff regarding the specific fan being serviced.

5.0 DELIVERABLES & REPORTING

The Contractor shall provide the following:

5.1 Completed Preventative Maintenance Service: Performance of all tasks listed in Section 4.0 for each fan during each scheduled service visit.
