J061--ELECTRICAL TESTING

of equipment is included in this contract as well as a dollar amount to be set aside for repairs. All inspections and testing procedures must meet the criteria of the original equipment manufacturer along with the latest editions of the following codes, standards and specifications listed: ANSI, IEEE, ICEA, NETA, NEMA, NFPA, JCAHO and VA regulations. The contractor shall be responsible for supplying all portable power required to power up any and all test equipment necessary throughout these tests. The use of normal or emergency building power will not be allowed. The contractor shall be responsible for securing all manufacturers information, curves, data, procedures and any other information necessary to conduct specific tests on equipment and systems. Prior to beginning field-testing, the testing organization shall submit test procedures and a detailed test schedule to the Electrical Supervisor for each item of equipment to be field-tested. No testing is to be performed until after the test procedures and schedules have been approved. The contractor shall be responsible for all coordination between Dominion Virginia Power (if applicable), station supervisory personnel and test personnel for scheduling shut-downs, system tests and tests on system components. The V.A Medical Center Electrical Staff will be responsible for conducting the actual scheduled outages and reenergizing of circuits and components on V.A. premises and V.A. owned equipment only. Lockout/Tagout of this equipment will be performed jointly between the V. A. Medical Center Electricians and the Contractor. The contractor will be responsible for removal and replacement of any and all breakers needing to be tested. All breakers being removed will be properly reinstalled. Any and all conductors removed from a breaker will be properly terminated back to that breaker and any and all lugs will be properly torqued to manufacturers specifications. Testing shall commence and be completed within nine (9) consecutive days, beginning on a Saturday and ending on the following Sunday. The specific dates shall be coordinated with the COTR. All outages shall be scheduled with the COTR two weeks in advance of testing start date. Testing dates may change due to inclement weather, however, the COTR shall first be notified and approve any changes necessary. Contractor shall anticipate all work to be done after normal working hours. Outages will be scheduled at night between the hours of 5:00 p.m. and midnight and between the hours of 7:00 am and 5:00 p.m. on weekends. However the Contractor should be prepared to work longer hours should problems develop to assure restoration of power. Daytime hours, during the week, may be approved under certain circumstances if there is no impact to building occupants. This would be a rare instance, thus Contractor should anticipate overtime hours for all contract requirements. Equipment Repairs: Minor repairs shall include but not be limited to such items as loose bolts, loose or broken lugs, wiring terminals, heaters, malfunctioning targets, dirty/high resistance connections, etc and shall be corrected on site during testing if possible. Repair or replacement of larger items such as breakers shall also be performed during this outage if possible. However if parts are not readily available, these items will be repaired or replaced under a separate smaller outage and will be scheduled after parts or components are available. Contractor shall set aside a line item not to exceed $50,000 for repair or replacement parts with this contract. All repairs shall be invoiced under this line item at the conclusion of the contract. This amount is to be used for bidding purposes. However a materials breakdown will be required with the final invoice and Contractor shall be paid actual costs with appropriate mark up s up to $50,000 for parts. Contractor is not to exceed this amount without prior written approval of the Contracting Officer. Minimum Equipment Test Requirements: 5 KV AIR CIRCUIT BREAKERS 1. The breakers will be removed from their compartments. The compartments shall be cleaned and inspected. Shutters shall be cleaned, inspected, and tested for proper operation. The racking mechanisms shall also be cleaned, lubricated and tested for proper operation. 2. All cable termination s, both primary and secondary, shall he checked for signs of overheating, proper tightness and support. 3. All exposed bus connections shall be checked for signs of overheating and for proper tightness. 4. The arc chutes will be removed, cleaned and inspected. 5. The entire breaker and the mechanism will be inspected. 6. The entire operating mechanism will be thoroughly cleaned, lubricated and exercised. 7. All of the interior components of the circuit breaker will be thoroughly cleaned. 8. The contacts and current carrying assemblies will be inspected for burning, pitting, arcing, worn fingers, garter springs etc. 9. The contacts will be cleaned and anti-oxidant grease will be applied to the breaker s main contacts. 10. The breaker contact resistance will be measured and recorded. 11. An insulation resistance test will be performed and results recorded. 12. The breaker will then be closed manually to ensure proper closing and trip operations. 13. Any and all interlocks will be checked and proper operation will be verified. 14. The breaker will be electrically operated when test stands are available, or the breaker will be operated from its cubicle, if the system allows. 15.
