Any questions or injuries shall be brought to the attention of the Post Occupation Safety and Health Officer (POSHO). As applicable, Material Safety Data Sheets (MSDS) shall be provided by the contactor for all HAZMAT materials. Copies will be provided to the COR for approval.

Follow manufacture specific maintenance and testing procedures, and general industry practices to ensure operational readiness of the buildings electrical switchgear. Perform cleaning, testing and training on these systems following procedures and general operational requirements for this type of switchgear. The contractor shall include the embassy Locally Engaged Staff (LES) assigned electricians in all aspects of this site work, providing “On the Job Training” (OJT) of the local staff as much as possible. It will be the responsibility of the contractor to explain proper safety and maintenance procedures as part of the OJT training program. No formal classroom training is requested or required.

This service contract is for planned maintenance only. If any discrepancies are found that are not covered under this scope of work then the contractor must provide the following:

1. Detailed report noting the discrepancy found.

2. Bill of Materials (BOM) to include component name, quantity, part #, and price for any repair material required and the material lead time noted.

3. Price quote for the estimated repair labor. This should be a not to exceed price and will be contracted separately from this service agreement.

The contractor must clean up after each task and place all maintenance associated trash in the proper embassy dumpster or approved trash container.

III. DESCRIPTION OF EQUIPMENT TO BE SERVICED:

The Embassy switchgears all are produced by CSGE. And ATS (Automatic Transfer Switch) are produced by ASCO.

IV. SCOPE OF WORK

Coordinate site visit service dates with the embassy Facility Manager (FM). Prior to beginning any site work the contractor must submit to the embassy FM an isolation Standard Operating Procedure (SOP) and schedule to reflect the planned work and sequence. The contractor must obtain written approval from the embassy Facility Manager noting the planned servicing schedule, and all required generator transfers, tie-breaker switching, or switchgear outages.

Provide basic consumable parts associated with the service and maintenance of the switchgear listed in section III. This must include, but not limited to, batteries for the trip units, fuses, and dielectric lubricant. Correct any faulty, damaged, discolored, and worn components using site spares. Provide a BOM to include part number and retail price for any noted deficiency found that cannot be corrected during this site visit. Note the faulty equipment or deficiency in a final service report. All follow-on repair action and material will be covered under a separate scope of work. At a minimum this service shall include the following:

A. Step-One, Visual Inspection:

1) Visual and Mechanical Inspection to insure the proper operation of all factory and vender installed meters, breakers, remote power monitoring equipment associated with the switch gear.

2) Inspect physical, electrical, and mechanical condition including evidence of moisture or corona.

3) Inspect that all filters are in place, and the vents are clear.

4) Inspect that the working space is maintained in front of all the electrical gear per the National Electrical Code (NEC) requirements.

5) Inspect that the electrical room is free from foreign articles not associated with the room.

B. Step-Two, Verify:

1) Compare the installed metering measurements with voltage and power readings from a True RMS meter. Make calibration corrections as necessary to ensure accurate voltage and power readings.

2) Verify the circuit breakers sizing match the drawings.

3) Verify the proper labeling of all the breakers in the switch gear.

4) Verify that the Post as-build drawings (electrical one-line) match the distribution system. Make “Red Ink” corrections on a paper copy as necessary. Inform the FM of any discrepancies or changes to the drawings.

5) Verify that the required NFPA70-E safety equipment is available and in good condition for local staff to use.

6) Refer to the manufactures recommendations for additional maintenance requirements.

C. Step-Three, Test/Clean/Correct:

1) Inspect anchorage, alignment, grounding for the equipment.

2) Test the system earth ground (25 ohms or less).

3) Perform infrared testing on all conductor connections, buss terminations. Only record hot spots on digital format for review.

4) Before shutdown insure that all components are operational. Record ones that are not at this time.

Make the FM aware of all components that are not functioning prior to shut down.

5) Schedule power outage of equipment for cleaning. Coordinate any required outage with post.

(Outage may require off hours work).

6) As applicable perform function tests on “rack-out” breakers, test trip units and settings. Replace any faulty battery, fuse, or switch.

7) Perform proper Lock-out/Tag-out and ensure the system is de-energized before removing panel covers and exposing any electrical bus or cabling. Under no circumstances should the equipment be energized during the maintenance operation.

8) Clean each compartment. Check for damage, excessive wear, or corrosion

9) Spot check and correct any loose components or connections.

10) Torque loose connections identified during the infrared test or during inspection.

11) Confirm correct operation and sequencing of electrical and mechanical interlock systems.

12) Use appropriate dielectric lubrication on moving current-carrying parts and on moving and sliding surfaces.

13) Correct any faulty, damaged, discolored, and worn components using site spares.

14) Exercise all active components. This includes racking the breakers out than back in.

15) Inspect mechanical indicating devices for correct operation.

16) Inspect all power control transformers for physical damage, cracked insulation, broken leads, tightness of connections, defective wiring, proper overload protection, and over all general wiring.

17) After re-energizing the equipment ensure that all components are up and functioning properly.

18) Refer to the manufactures suggested recommendations for additional maintenance requirements.

19) Clean or replace any air filters present.

20) Make calibration corrections as necessary to ensure accurate voltage and power readings on permanently installed switchgear metering.

V. GENERAL REQUIREMENTS

Prior to the start of work, the contractor shall customize a work sheet to match the equipment or us a factory supplied one outlining the sequence of events and tasks to be preformed and must submit for review this work sheet and/or check lists that will be used for performing maintenance service.

The Embassy Facility Manager must immediately be made aware of any condition discovered that could result in equipment failure.

Test and inspection field report shall be submitted within 30-days of completing work.

Safety: Safety is the highest priority on this and all OBO/CFSM/FM projects. The contractor shall direct all of those under his charge to work safely. Strict adherence to NFPA70-E and applicable OSHA standards must be maintained at all times. Regular safety meetings shall be held among on-site contractor personnel, LES staff assisting. Safety concerns shall be brought to the attention of the Post Safety and Health Officer (POSHO) and the COR.
