3 Year Switchgear Maintenance
Department of Veterans Affairs (VA)
Veterans Health Administration (VHA)
Oklahoma City VA Health Care System

BRIEF SCOPE OF WORK
(This is for information only)

PURPOSE: Oklahoma City VA Health Care system requires the contractor to provide required 3-year switchgear preventative maintenance inspection, and testing on all circuit breakers, in accordance with the Performance Work Statement (PWS), in an efficient and cost-effective manner, supporting the VA mission.

This is a non-personal services contract. The Contractor, its employees, agents and
subcontractors shall not be considered VA employees for any purpose of fulfilling the PWS and shall be considered employees of the Contractor. Contractor shall furnish all labor, materials, parts, equipment, tools, shipping, transportation, insurances, licenses, certifications and supervision necessary to provide services in accordance with this Performance Work Statement (PWS). For a contract of this size, scope and complexity, the successful Contractor must perform in a professional manner as recognized by commercial industry standards as good to excellent.

TASKS and REQUIREMENTS:

The switch gear is required to be serviced every 3 years for preventative maintenance.

SWITCHGEAR:
Clean, inspect, test and adjust all major electrical distribution equipment. This shall include the electrical distribution equipment and transformers in the following locations: See attached inventory list to be serviced.
1. Sub-Stations: No. 1, No. 2, No. 2.5, No. 3 & No. 4.
2. Animal Research Facility.
Execute work to interfere as little as possible with normal functioning of the medical center. All outages shall be scheduled and approved in writing at least two weeks in advance.
REPORT:
A. The contractor shall provide a complete comprehensive report on the results of the services rendered. The report shall provide for listings of all equipment tested and scanned including complete nameplate data, age, maximum loading in amperes, the conduction as found, and modifications made. In addition, the contractor shall make recommendations including any major defects or deviations in the electrical system detected during the test and inspection and any violations of national or local codes that may affect the safety of personnel and/or continuity of service. Complete a check- list for each piece of equipment. The check- list shall have a line item for each test and inspection to be performed. All critical conditions, including recommendations for corrective action shall be submitted in writing.

INSPECTION, TEST, MAINTENANCE AND REPAIR:
Testing shall be performed in compliance with applicable NEMA, ANSI, ASTM, ASA, NFPA and VA standards. The following equipment shall be inspected, tested and/or repaired in this project:

ENCLOSURES AND CUBICLES: The inside of the enclosures housing electrical switchgear shall be cleaned with a vacuum cleaner with insulated attachments. Keep generally free from dust, lint, dirt, and abrasive material. Clean all buses, supports, etc. Buses and connections should be inspected for signs of overheating and weakening of insulation. Buses shall be inspected for adequate support spacing and bracing in accordance with the NEMA Standards for bus bar bracing. All structure supports will be checked for Tracking and anchor bolts will be checked for tightness. All control connections, screws, lug, bolts, solderless connectors, etc. will be checked for tightness to ensure good electrical continuity and mechanical condition. Inspect the ground for a solid, continuous, and adequate ground. The connections shall be cleaned and tightened. All raceway systems entering the switchboard shall be inspected to determine that they are properly bonded with lock nuts, etc. Service entrance equipment shall be checked to see that it is grounded in accordance with current NEC requirements. All switch gear compartments shall have the backs removed to allow complete cleaning. All front compartments shall be cleaned and lubricated as necessary, following manufacturer specifications.

CIRCUIT BREAKERS: Electrical test shall be made on all circuit breakers by subjecting them to actual operating current to ensure that they will operate within the same limits after service as when new. Adjustments shall not be attempted by anyone other than trained service personnel having the necessary tools and test equipment. The breaker shall be beggared at no greater than 10 percent of its rated voltage. The megger readings must be taken with the breaker closed and latched. Megger readings must be taken from each pole to the breaker frame and from each pole to each of the other poles. The interlock mechanisms should be inspected and tested to ascertain that they are functioning as designed. On a breaker with a 240-volt control, the minimum Megger reading should be one meg-ohm.

All circuit breakers shall be removed from service and inspected for loose, broken, or defective parts. All current contacts shall be inspected, cleaned, and polished as required. All bolts, cutter pins, rollers, and bearings shall be examined to determine if any defect, looseness, or unusual conditions exist. All linkages shall be examined and lubricated as required. All arc chutes, barriers and insulation shall be examined for broken or burned areas. All parts shall be cleaned as required. The circuit breaker shall be reassembled. The circuit breaker shall then be tested for electrical tripping using approved low voltage, high current test equipment or trip tested by stimulated CT current through the time over-current relay devices in accordance with the manufacturer s specifications and published standards.

No change in trip device setting from as found shall be made by the contractor without expressed approval.

SWITCHES-DISCONNECT, TRANSFER SWITCHES, SWITCHGEAR, ATS S AND GENERATOR SWITCHGEAR: Where possible, the main contacts of the switch can be cleaned, adjusted and a thin film of lubricant placed on them. The fuse clips, connections to the bus or cable, mounting in switchboard, and handles shall be checked for tightness and proper alignment. When applicable, the tension on the contacts may be checked with signs of -discoloration caused by heating are noted. After exercising the switch several times, cleaning and making any adjustments necessary, with a conductor test set, the resistance drop across each phase shall be measured. If the drop has greater than + 20% variation between phases, part replacement should be recommended. Generator switchgear, where possible, shall meet -maintenance requirements per manufacturer s specifications.

RELAYS: Relays shall be checked with a current and accurate timing device. If a relay does not give the desired operating time for a given current, the desired time can usually be obtained by cleaning and adjustment. Only qualified personnel, properly trained and properly equipped with test equipment, manufacturer s data, and necessary special tools, should work on this equipment.

INFRARED SURVEY: Thermo-vision equipment shall be utilized to scan all electrical equipment and terminations in the locations previously specified. All hot spot , those which measure greater than 8 degrees (Celsius) higher than die reference temperature (ambient) shall be photographically recorded and included in the Engineering Report to be submitted.

The areas adjacent to the proposed addition shall be continuously occupied by the OKC VAMC. The Contractor shall implement phasing to ensure that the construction will not impact or impede the VAMC s mission to care to the Veterans.

The contractor shall provide quality control of all work conducted and the individual appointed shall be competent and educated/experienced in the field of work this scope encompasses.
Codes and Standards: The Contractor shall follow all applicable codes and standards to this type of work including but not limited to Health Care System Memorandums (HCSM), OSHA Guidelines, NFPA 101, NFPA 70, Lock-out-Tag-out, and Rules of Station.
The C&A requirements do not apply, and that a Security Accreditation Package is not required.
