3 Please confirm who is responsible for applicable signage and VA specific identifiers at the transformer.

4 We cannot find the Pump House on Drawing E-2 dated 06/12/80. Is it identified as something else on Drg E-2? If not, can you please provide a One-Line Drg that includes the Pump House

5 On page 6 of 48 of the Solicitation, you are asking for dual feed transformers on all 5 transformers. However, Drg E-2 shows the transformer at the Laundry to be single feed.

Since you have identified custom transformers, if required, to meet the sizing of the existing transformers, do you want the new transformer for the Laundry to be single Feed?

6 Is the transformer for the Pump House single feed or dual feed?

7 Do any of the existing transformers have pcb (polychlorinated biphenyl oil) contamination? If so, which ones are contaminated?

8 Please identify where we are expected to connect the temporary generators for each of the 5 transformer replacements and provide 1-line diagrams for those services & switch gear.

Contractor responsible for all signage.

15 Will the Con Ed shut off the power or not?

16 We believe that the Transformer for the Pump House Bldg 176 is on its own separate Con Ed Service and that transformer feeding the Pump House is a Con Ed Transformer. Please verify if this is true, and if it is; please remove this transformer from the Scope of Work and from the pricing sheets/forms.

Any shutdown of incoming utility power would need to be coordinated with Con Edison and the VA in advance. The contractor should not assume that Con Edison will shut off power without an approved outage request, utility coordination, and a VA-approved shutdown plan. If the work requires de-energizing utility service or primary feeders, the contractor should identify the required shutdown duration, affected loads, sequencing, and restoration plan for VA review and approval.
