No award will be made off of this posting. INTRODUCTION The Department of Veterans Affairs, Veterans Health Administration (VHA) has a requirement to conduct Switch Gear maintenance at the VA Medical Center (VAMC) in Oklahoma City, Oklahoma. This is a one-time switch gear service requirement (that is to be completed every 3 years for preventative maintenance). Contractor shall provide all tools, equipment, labor, supervision, transportation, project management, and materials to do the one-time annual preventive maintenance, inspection, and testing on all circuit breakers. Â SCOPE OF WORK Switch Gear Clean, inspect, test and adjust all major electrical distribution equipment. This shall include the electrical distribution equipment in the following locations: 1. Sub-Stations: No. 1, No. 2, No. 3 & No. 4. 2. Building No. 19 and ARF. 3. Room BF-118. 4. Boiler/Chiller Plant. 5. Mechanical/Electrical Rooms: Building 19 Mechanical Rooms (3) total, 3rd floor Fan Room, 3rd Floor Mechanical Room, 5th Floor Mechanical Room, 6 Floor Mechanical Room, 8th Floor Mechanical Room, 8th Floor Mechanical Room North, and Generator Rooms (5) total. Repair as needed all open/close indicators and charged/discharged indicators in sub-station 3 type AK breakers. Execute work to interfere as little as possible with normal functioning of the medical center. Schedule all work in specific areas with the Resident Engineer to enable Engineering Service to make any necessary arrangements. Coordinate with the Resident Engineer in advance of any outages. Only after the approval of the schedule outages, by the Resident Engineer, work can proceed accordingly. All outages shall be scheduled and approved in writing at least two weeks in advance. Outages will be scheduled only at night and on weekends. 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 to the Resident Engineer. B. For generators report shall indicate: nameplate data including manufacturer, age, capacity, KW load under emergency conditions, fuel type, number of hours of fuel tank capacity, reliability, transfer time, number of hours of accumulated run time and if mounted above, on or below grade. 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 of the Resident Engineer. 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: Thermovision 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. Preventive Maintenance: The Contractor shall provide preventative maintenance according to the applicable schedule or intervals established by the original equipment manufacturer (OEM) for each model of equipment. The preventative maintenance schedule will be reviewed and approved by the government Program Manager before beginning such program. Such preventative maintenance shall consist of, but not be limited to, the following: Quarterly, annual, and triennial OEM recommended preventative maintenance services and inspections shall be performed and shall adhere to OEM instructions and intervals of the Equipment Operation and Maintenance Management Schedules and shall include, but not be limited to, the following: Use only fluids and lubricants that are approved by the OEM.
