Not dedicated on-site but the Quality Management Plan should outline the role of the quality control manager.

6 Please confirm the commissioning agent is provided by Ames National Laboratory.

Confirmed

7 Please confirm BIM Coordination is required on this project.

Confirmed. The drawings have been developed in Revit but not all existing infrastructure is modeled.

Confirmed

11 U1.10 shows a load bank between the gensets. Is a permanent load bank needed? If so, please provide specifications and details on connection to the electrical system.

No, a permanent load bank is not desired. One should be provided by the contractor for commissioning.

12 2.8 2. The diesel genset is specified as a “walk-in” style enclosure but the NG genset is not. Please advise.

Both gensets shall be level 2 sound attuned manufacturer enclosures. No walk in is desired.

13 2.8 G. Working platforms are specified for the diesel genset but not for the NG genset. Please advise.

No working platforms needed, provide level 2 sound attenuated manufacturer enclosure.

14 3.7 A maintenance contract is specified on the NG genset but not the diesel genset. Please advise.

Please provide a maintenance contract for both generators.

15 No circuit breakers or load break switches are shown on the 5kV generators. Please confirm none are required.

M1, M2, G1, M3, M4 & G2. These will not fit within the gear layout as shown unless they are fixed mount in the cable compartment (not optimal) or top hat mounted on the roof of the swgr. Is this acceptable?

PT locations will be addressed in Addendum 3.

21 Typically, 3 phase PTs are furnished on all incoming sources. Drawings reflect single phase.

For value engineering, the three-phase measurement is on the bus while line side is used for syncing.

22 Are the furnished schematics an accurate as to how the equipment is intended to be wired?

Olsson schematics describe the minimum performance requirements of functionality and do not indicate all internal wiring. Olsson schematics may include place holder terminal blocks that are desired in the terminal cabinet for convenience.
