Q: Specific sheet note #3 indicates items shown with light line weights are existing, however, all lines appear to be the same density.

Q: The RFP FA4626-09-R-0021 page 3 of 43 indicates nameplate information that is not listed on the one-lines. It is difficult for me to determine what I need to provide a quote on.

A: I believe the confusion is with the NSN that this number is generated by Contracting’s Procurement System. This is not name-plate data. The intent is to provide and install equipment per the drawings and specifications. This can be addressed further at the site visit.
