a. All molded case circuit breakers (frame sizes 225 amp or less) shall be exercised open and re- closed, documented and done during the outage to specific equipment in conjunction with scheduled outages of gear. This work will be performed by VA staff.

WORK SCHEDULING

Contractor shall furnish to the COTR three (3) weeks in advance of scheduled work, a written proposal of scope of work and the equipment to minimize outages to effected areas.

Power Outages:

The power outage for work on Building #21 may be scheduled for a time convenient to both parties, Medical Center and Contractor. Main Substation Breakers #3 and #9 may be opened, disconnecting the feeders, to make available the equipment within the building for work.

Maintenance and testing of the Medical Center s emergency power generators and associated equipment will require close coordination between the two parties. Power outages will only be permitted at night or on weekends. Separate outages must be scheduled for maintenance on each generator. Generators to be serviced are (1) 125 KW generator located in Building #6, (2) 600 KW (480V) generator located in Generator Room attached to Building #1, (3) 600 KW generator located in Generator Room attached to Building #1, and (4) 400 KW generator located in Generator Room attached to Building #1. (1) 100kw generator located in bldg 11, and (1) 125 KW generator located in bldg 12.

Outages effecting D-wing addition and Buildings 3, 4, 5, and 12, and Breaker #5 in the main substation shall be scheduled to be deactivated. This will permit work to be done on the primary side of the 480 V system and pad-mounted Transformers T-4, T-12, and T-1.

After work has been completed on the feeder from Breaker #5, the main substation shall be scheduled down for work on the primary system. During this period, only emergency generator power will be available.

After work on the substation has been completed, the power outage to Buildings #1, #6, and #19 may be scheduled. During this outage, Breakers #6 and #10 in the main substations are turned off. During this outage, power will be applied to all the 480 V circuits in Building #1. Also, by withdrawing Breakers #18, #19, and #22 from, their racks in the main switchgear in subbasement #2 of Building #1 and Breaker #5 of the 208 V distribution switchgear for the C&E Addition of Building #1, emergency power from the 600 KW generator can feed panels EEQ, ELS, EC and EDPE4 without endangering persons working on Feeders #6 and #10 and their associated gear. Breaker #8 will be turned off to inspect and test 480 V switchgear in A001. It should be noted that no work can be performed on the aforementioned panels if the 600 KW generators is not running during this period. Also, during this outage, power will be supplied to the Boiler House, Building #8, by the 125 KW generator located in Building #6. By withdrawing Breaker #2 from the switchgear in Building #6, the Contractor can safely work on the switchgear in that building.

At a time convenient to both parties, Breaker #4 of the main substation can be deenergized to permit work on pad-mounted Transformer T-2, T-7, and associated distribution panels of Building # 7. Service to other portions of the Medical Center is not affected by Breaker #4 being off only Buildings #T-20 and Building #7.

The following work may be done within the normal five day work week during the heating season months of October through March or at a time to be determined by the VA Medical Center when load is at a level to permit testing:

Building #21 primary system work

Hi-Pot of Building #21 feeders from Circuit Breakers #3 and #9

Low voltage breakers in Building #21

Within the normal five day work week during months of milder temperatures:

Generator and transfer switches: Generator test run should be scheduled as well for evening or weekend times.

Weekend or evening hours work during milder months:

Main substation work with one side of the substation, Clifton or Hillcrest, being scheduled down during a weekend.

Primary side of system fed from Circuit Breaker #5. Hi-Pot the feeder during this outage. This work will preferably be scheduled at the same time as work on the Hillcrest side of the main substation.

Hi-Pot on feeders from Circuit Breakers #6 and #10. Available one at a time, during evening hours on weekend days.

Weekend or evening hours work not affected by weather or season:

Low voltage work on buses, breakers and switches (Building #1, #6 and #19).

Proposed 5 day work schedule:

SCHEDULE Plan for evening start 6pm to possibly 12:30am:
