Q1. Attachment 1 titled SOW dated 14 JUL 2017, released on 16 JUL 2017, calls for the following in sec 7

(Submittals), sub section 7.3:

7.3 Submit coordination study for UPS prepared in accordance with IEEE Std 242 Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems; demonstrate fully selective coordination with immediate upstream and downstream over current protective devices

In reviewing this requirement, to fully complete this, we would need knowledge of power upstream of the UPS and at the building level. The building design or any part of the electrical distribution is outside of the SOW for this RFQ so we are wondering if this should be accounted for in our package or fall outside of the scope of the RFQ.
