A15. Refer to the Government’s response to Question 12.

16. Outline drawing showing shipping dimensions.

A16. The GE Transformer Outline drawing (reference drawing 583E464 and included in the amendment) shows the overall dimensions of the transformer and the as-shipped dimensions when it was delivered to the dam.

A17. Refer to the Government’s response to Question 12.

18. Does Barkley Dam have any area that would allow for the transformers to be broken down close to the switchyard area? This would help with shipping weights. It would require no more than 7-days for each transformer to disassemble.

A18. No, see amended specification 26 05 00.00 26 section 3.2.1, Transformer and Neutral Reactor Removal Procedure. With the exception of removing the high-voltage bushings and the radiators, as required for shipping the transformers to the disposal site, the transformers shall not be disassembled on site. Removal of the transformers and neutral reactors must not begin prior to approval of the removal procedure.

19. Can we schedule a walk down in near future?

A19. Physical access will not be available until after contract award. The virtual site visit video and audio will be available until bid opening at the previously provided link.

A20. See updated drawing E-201 in the amendment.

21. Name of short line rail that services site.

A21. Paducah and Louisville Railway (P&L). Access to the rail at Barkley Dam will need to be coordinated with P&L. The contractor will be responsible for coordination and determining how to safely unload equipment from rail to site if they choose to use this resource.

22. Section 02 41 00.00 26 Demolition, 1.2.3 Description of Demolition Work:

a. Are either of the transformers considered “converted from a PCB transformer or a PCB-Contaminated transformer” per the TSCA regulations 40 CFR 761?

b. Are the 26 bushings that are attached to the 2 transformers the only bushings in the scope for characterization and disposal?

c. Section 1.2.3 e. states that all bushings are to be considered PCB equipment which is interpreted that the equipment meets the definition per the regulations 40 CFR 761.3 definition for PCB Equipment. Do we assume > 500 ppm PCB? The costs to treat and dispose are much higher for >500 ppm.

d. If known, what are the bushing weights and volume of oils in the bushings? Otherwise, we will estimate and validate upon award.

A22.a. The two government transformers on-site are original to the construction of the Power Plant and have not been converted from a PCB Transformer or a PCB-Contaminated Transformer. Oil test results are located in specification 01 95 00 Forms and Attachments, Attachment 8, page 426.

A22.b. Contract drawing ED101 shows that there are two bushings on each neural reactor, an oil filled HV bushing and a solid Bulk bushing. This contract drawing also shows that each transformer has six low voltage solid bulk bushing, one neutral solid bulk bushing and three oil filled high voltage bushings.

A22.c. See amendment specification 02 41 00.00 26, section 1.2.3.e. All available PCB oil test results are located in specification 01 95 00, Attachment #8, Attachment #9, and Attachment #10.

A22.d. See reference drawings 150-020-T-427-00, 89493-61-70, and POC750_0800S for the transformer bushing outline drawings. See Attachment #12, in amended specification 01 95 00, for photos of available name plates.

23. Section 02 84 33 Removal and Disposal of PCBs, 1.1 General Information:

What is the capacity of each of the 6 oil storage tanks located in the Powerhouse? Is it the 3,200 gallons each based on a total capacity of 19,200 gallons of oil referenced in Section 02 41 00.00 26, 1.2.3?

A23.. Per reference drawing Q9-79/504.2, the capacity of each tank is 4,340 gallons each. Per specification 02 41
