It is my understanding that the hatched lines on drawing E-05 reference removal. Please reference demolition note #1 on E-07 it directs us to remove completely the conduit and wire between Blower house #1 and Blower house #2, yet on E-05 this same conduit is not shown to be removed. What drawings will take precedence?
E-05, E-06, E-07 The conduit can remain as a spare conduit. However, the wiring must be removed completely.

Section 40 62 00, Part 2.01 references specifications for a workstation, spare workstation and software licenses but none are indicated in the electrical or instrumentation drawings. Please confirm this is not in this project scope.

Section 40 61 13.01, Part 2.03, subsection D references specifications for a UPS, however, the electrical drawings seems to indicate the UPS is external to PC-1, RIO-1, RIO-2, and RIO-3. Electrical specifications section 26 33 53 seems to suggest this will be supplied by someone other than the system integrator. Please advise.
