8. Bidding Schedule item “Existing outdoor electrical equipment and material” includes repairing, testing, and removing and disposing of the following existing outdoor electrical equipment and material:

a. Material to be repaired and tested:

(1) One (1) 230-kV porcelain bushing on existing power transformer KV1A. Includes performing dye-penetrant testing of the broken areas of the porcelain for crack propagation and repairing, painting and sealing the broken sheds of the 230-kV Pecor bushing. The bushing shall remain in place and shall not be removed. Individuals completing these repairs shall each have a minimum of 10 years’ experience performing electrical porcelain repairs. The Contractor shall submit their qualification, repair procedure, materials data, and a minimum of three industry references to the COR for approval.

(2) Dye Penetrant Testing: The Contractor shall clean the bushing and perform a dye penetrant test on the entire area of each broken shed to determine if there are any cracks that propagate from the surface into the bushing. Results of these tests shall be photographed and sent to the COR.

(3) Broken Shed Repair: Repairing the broken sheds shall include chemically treating the broken surface to improve attachment, recreating the shed with a material with thermal expansion criteria matching porcelain and securely attached to the bushing in place of the broken shed, and sealing with a fluorourethane insulator coating that matches the color of the porcelain glaze.

b. Material to be Removed and Disposed:

(1) One (1) 230-kV, 167 MVA power transformer designated KV2A. The power transformer contains 15,400 gallons of oil and has a total weight of 347,600 pounds.

The oil in the bushings and power transformer have been tested and contain less than two (2) parts per million (PPM) polychlorinated biphenyl (PCB).

(2) One (1) 230-kV oil-filled power circuit breaker designated JV2A. The power circuit breaker contains 5,175 gallons of oil and has a total weight of 68,550 pounds. The oil in the bushings and power circuit breaker have been tested and contain less than 2 PPM PCB. The oil in the bushing potential device has been tested and contains 2 to 49 PPM PCB.

(3) One (1) 115-kV oil-filled power circuit breaker designated JY2A. The power circuit breaker contains 2,370 gallons of oil and has a total weight of 33,200 pounds. The oil in the bushings and power circuit breaker have been tested and contain less than 2 PPM PCB. The oil in the bushing potential device has been tested and contains 2 to 49 PPM PCB.

(4) One (1) 13.8-kV disconnecting switch designated WW2A.

(5) Substation Control and Power Cables: Control and power cables shall be disconnected from equipment as shown on the Drawings. The portion that is buried underground shall be abandoned and the portion in conduit or trench shall be removed and disposed. Western will disconnect control cables in the service building prior to removal.

(6) Miscellaneous aluminum tubing, aluminum conductor, conduit, and exposed and buried ground cables.

(7) The Contractor shall include any credit to the Government for salvage of the equipment above in this bid item.

Message from the Administrator

At Western, we show our commitment to safety every day through the actions we take, the training we offer and the work conditions we provide. We expect the same commitment to safety from each of our contractors who provide products or services to Western. In performing work for Western, all contractors must make the right decisions to ensure that the work environment is as safe as possible.

Our safety program is based on four points:

Safety procedures or common sense must be applied by each

Federal and contract employee. Safety should not be set aside to meet a project schedule or for personal convenience.

Employees and contractors must believe that they have the right and the responsibility to identify and take action to reduce, if not eliminate, hazardous work environments and hazardous work practices.

Managers and supervisors must lead by example and execute their responsibility to ensure each job is accomplished in a safe and healthy way.

Safety is a personal responsibility. Each individual makes the decision on what action to take to accomplish a task.

By integrating these principles into every task we take, together we can ensure Western is a safe place to work.
