Combined Synopsis Solicitation No. 1333MF26Q0102 Response to Questions:

1. If you wish us to quote the actual part, we would need a part number, please. Or a picture of the nameplate of the existing unit would be extremely helpful as well.

Make: Eaton ATC 300+ Model #: ATC3C2X40400XDU Serial Number #: 044447

2. There is no detail in the attachment about the ATS itself. Can you please provide the amperage, voltage, cabinet, bypass/non-bypass, SER rated, etc.?

AMPS: 400

Volts: 480 Cabinet # 478C642H01

3. I will need more details on what is existing to be able to provide pricing. Do you have the serial # off of the existing ATS that is being replaced? Are there any one-lines or specifications available?

Make: Eaton ATC 300+ Model #: ATC3C2X40400XDU Serial Number #: 044447 Line drawings or blue prints indicating routing of power lines into the campus would have to be cleared by security office as they are details about the critical infrastructure on the campus.

4. Please confirm the required ATS configuration, including transition type, service-entrance rating, and whether a 3-pole or 4-pole switched-neutral arrangement is required.

5. The RFQ states that the contractor shall remove and dispose of the existing ATS and “associated switchgear.” Please clarify which equipment is included in this scope and identify what must be removed, replaced, modified, or reconnected.

The contractor will remove the defective transfer switch controller and remove from the campus all packing material, defective parts that will be replaced (defective switch gear) that is associated with the project.

6. Please provide the maximum allowable electrical shutdown duration, any required outage windows, and whether temporary power is required during the replacement.

The transfer switch controller that is to be replaced provides power to the Maintenance Building, Boiler and AC Control Room. When power is cut for the replacement of the defective equipment the campus will be without Air Conditioning. Coordination with the Campus POC (Michael Cordova) will have to be made in advance so that staff members can be diverted from the campus. Ideally work can be accomplished either during after hours (starting at 5:00pm, weekend or non-campus work day. With coordination the interruption of the day to day work can be minimalized.

7. Existing Power System Models:

Will the Government provide existing SKM or other power system models for each facility? If available, will the editable/native model files be provided to the awarded consultant?

Prints and files will be made available to awarded contractor for use on site.

8. Previous Study Reports and Drawings:

Are previous Arc Flash Studies, Protective Device Coordination Studies, Short-Circuit Studies, and electronic single-line diagrams available for review?

Sent directly to COR to large to attached here

9. Access to Energized Equipment:

Will qualified Government personnel/electricians be responsible for opening all energized electrical equipment, including switchgear, switchboards, panelboards, MCCs, ATSs, transformers, and other equipment, during the site survey? Or is the consultant expected to provide qualified electricians to perform this work?

The campus personnel will open (unlock) the panels and buildings where the work will be performed, however, the opening all energized electrical equipment, including switchgear, switchboards, panelboards, MCCs, ATSs, transformers, and other equipment will be done by interested qualified parties.

10. Electrical Equipment Inventory:

Will the Government provide an existing electrical equipment inventory for each facility, including switchgear, switchboards, panelboards, MCCs, ATSs, transformers, disconnects, generators, and other major electrical equipment?

Listed in study sent to COR.

11. Electrical Inspection / Field Verification:

For the required electrical system inspection and field verification, please clarify the expected level of inspection. Is the consultant expected to perform only a visual inspection and collect nameplate data, or is a detailed internal inspection required?

The appropriate industry standard that will keep us in compliance and allow for the panels to be certified.

12. Is there a current SLD for the facility for the electrical distribution systems?

One is available on campus but not authorized to release, Prints and files will be made available to awarded contractor for use on site.

13. Are there One-line diagrams for new construction if not represented on Facility one lines available?

One is available on campus but not authorized to release, Prints and files will be made available to awarded contractor for use on site.

14. Is there a prior electrical study completed within the last 6 years that can be provided?

Last study was the ARC Flash Study conducted in 2023

15. Is there a complete software model for the facility.

There is not a digital model available, only hard copy

16. Is there an up-to-date electrical site plan for the facilities?

Yes

17. Will the center be coordinating and providing the current required utility information to execute the analysis?

Available on campus but not authorized to release, Prints and files will be made available to awarded contractor for use on site.

18. The SOW does not require an emergency power analysis, is this correct?

Yes

19. The SOW does not require a facility grounding assessment, is this correct?

Yes

20. Is there any electrical equipment located in places that would need to be surveyed oA hours or weekends?

No

21. Will a full-time escort be provided to unlock doors and show around the team during the Site Investigation?

Yes

22. Are any hot work permits, safety plans, or documentation required prior to being onsite and conduct the investigation on energized equipment?

It is the contractors requirement to be incompliance with applicable regulatory requirement set by the city and state regulators.

23. The SOW calls out “89 electrical panels which need to be certified as safe from Arc Flash.”

As Arc Flash labels are to be installed on any equipment they maybe worked on while energized, does this number include the other electrical equipment that may require an Arc Flash Label?

Detailed listing of previous ARC Flash Certification was provided to COR (in separate document)

24. Who is to conduct the Required Field Verification for the final report? Is the Contractor walking it back down or is the station backchecking it.

It will be a joint verification.

25. Will there be reviews performed by the center and if so how many, when and duration?

What reviews are they referring to?

26. Will there be electricians provided to open the electrical equipment, or will the contractor need to provide their own?

All RFI’s have been answered, request no extensions.

29. We understand from Amendment 0001 that this is a new study and that electrical drawings, one-line diagrams, panel schedules, and campus maps are not currently available for distribution.

Could you please confirm whether any other system information is available electronically, such as a partial equipment inventory, utility data, protective-device information, or equipment photographs? If no additional information is available, we will prepare our quotation using only the information currently posted on the solicitation portal and contained in the published solicitation documents and amendments.
