• 36C25626R0023 RFI Answers
  Proposal RFI #1 Drawing E502 (partial one-line) shows 5KV switchgear feeding transformers and 15KV switchgear feeding transformers. Is that accurate? What is the primary voltage of all the transformers? Can we get that included in the table on drawing E501.
  Use drawings E401-E406. Drawing # 502 detail 4 show existing 5KV switch gear at building 88 has been removed. Everything is 15KV.
  Proposal RFI #2 Can we get a one-line that shows all the transformers and manholes? Similar to drawing E502 but will all the transformers and manholes. See the attached marked up E502 that shows the transformers I was able to deduce by the buildings they are feeding (per the table in E501). Note that one of the manholes we looked at during the site visit was outside of Building 69, and it has cables running through it with T-connectors tapped off to feed a load that was assumed to be the nearby Transformer 18, but drawing E502 shows a separate unlabeled vault feeding T18. So drawing E502 might not be very accurate anyway, but it could be a good starting point, and it would helpful if the loops were color-coded.
  Attached drawings are for information only.
  Proposal RFI #3 Can we get a bid extension of at least two weeks?
  See P0003 Block 11.
  Proposal RFI #4 Can we schedule another site visit and walk to every transformer that is being replaced? Can we also look at the switchgear feeding the loops, and can we see the sites where the sectionalizers are going to be installed?
  An additional site visit will not be authorized.
  Proposal RFI #5 Can we assume that the cable feeding each transformer will need to be replaced because it s impossible to know if the existing cables will be long enough to reach the new transformer terminals? Can we get approximate (or assumed average) distances from the separable connectors to the transformers?
  The intent is to procure replacement transformers with similar connections that do not require addition...
