Q: What are the voltages?

A: Please refer to Exhibit A attached to this Addendum.

Page | 3

Q: Is FSDB looking for new or refurbished transformers?

A: FSDB would like pricing for both options. An updated Appendix H – Vendor Price Proposal has been attached to this Addendum.

Q: (FSDB) What is the lead time for a new transformer?

A: Based off lead times for generators, possibly 30 weeks.

Note: Do not let the time of performance in the sample agreement draft prevent you from submitting a bid. It will be adjusted according to the selected vendor’s project schedule and timeline.

Q: If transformers are shipped to the campus, would FSDB have a lift to move the equipment?

A: FSDB does NOT have a lift, but a lull. The vendor is responsible for moving equipment for this project.

Q: Is this project funded by federal money?

A: No.

Q: (Regarding the transformer located behind Wilson Music Center, building #50) Would FSDB like to level this pad?

A: Yes.

Q: Are vendors able to take down the fence during removal and installation?

A: Yes, however, vendors are responsible for putting in back up.

Q: Will the wiring remain the same?

A: Yes.

Q: Why is FSDB replacing these transformers?

A: Due to age and condition.

Q: Do you want to modify for an external port, for your oil sample report?

A: No modification, as another company provides FSDB that report.

Q: Are replacements to be consecutive?

A: Yes, or can be scheduled for different days.

Note: Work is to take place on Saturday or Sunday.

Q: Is there road access (regarding the transformer located by Settles Gymnasium, building #17)?

A: Yes, there are multiple access points.

Note: Vendors were shown the main access point which would require the least amount of navigation between buildings.

Q: If the awarded vendor has a lull, are they allowed to drive it through campus to reach the transformers?

A: Yes.

Q: If the awarded vendor needed to schedule an alternative date for replacements, how long would that process take?

A: Approximately a month.

Q: Are vendors able to bring other motorized vehicles onto campus (besides lulls)?

A: Yes, subject to FSDB approval.

E. Site Visit

Walk through project locations with FSDB Project Manager.

Site Discussion Notes:

• A word document version of Appendix G (titled PUR 7801) is posted to the FSDB website: Purchasing | FSDB

• Vendor is responsible for the disposal of the old transformers. FSDB does not have a place to store them for refurbishment.

• Storage is available for vendors and will be coordinated between the awarded vendor and FSDB project manager.

• Transformer specs and photos have been attached as Attachment A of this Addendum.

• All staff working must have Jessica Lundsford Act (JLA) badges. The only exception being deliver drivers, however; drivers still need to have a valid Driver’s License and no warrants or anything else that would prohibit them from being on school grounds.

The awarded vendor should also send their badging information to the project manager, Greg Peacock as well; we have had some difficulty with our electronic filter holding emails.

Q: Cost? A: Between $85 to $100 per person. The badges are good for 5 years.

F. Conclude

1. Minutes of the Site Visit will be issued as Addendum #1 and posted to the FSDB website in the Purchasing Competitive Solicitations Dropbox folder by October 21, 2026.

2. Submit all questions in writing to the attention of Elizabeth Nimitz no later than October 23, 2026, at 4:00PM by e-mail: nimitze@fsdbk12.org.

Secondary (Low Voltage)

• 208Y/120 V o 208 V phase-to-phase o 120 V phase-to-neutral o 4-wire grounded wye

HV Tap Settings

The transformer is presently set to whatever tap position the internal changer is on; the nameplate does not indicate the current tap.

Insulation / BIL

• HV BIL: 95 kV

• LV BIL: 30 kV

• Neutral BIL: 30 Kv

Impedance

• Impedance: 4.5%

Weights

Tap Voltage % Above/Below Rated A 13,860 V 5.00% B 13,530 V 2.50% C 13,200 V Rated D 12,870 V -2.50% E 12,540 V -5.00%

Component Weight Core & Coil 1,762 lbs

Tank & Fittings 1,207 lbs Fluid 1,362 lbs

Total Weight 4,331 lbs

Fluid

Based on the 1999 manufacture date and the OA classification, this is most likely a mineral-oil-filled unit unless a special dielectric fluid was specified. The fluid type is not shown on the visible portion of the nameplate.

Full Load Current

Using the nameplate ratings:

Primary Current @ 13.2 kV

≈ 13.1 amp

Secondary Current @ 208Y/120 V

≈ 833 amps

Short-Circuit/Fault Current Estimate

With 4.5% impedance, the theoretical secondary available fault current at the transformer terminals is:

• ≈ 18,500 amps symmetrical (18.5 kA)

Actual available fault current at your downstream service equipment will be lower depending on secondary conductor length and impedance.

Current Transformer located by Settles Gymnasium, building #17

General Information

• Manufacturer: Cooper Power Systems

• kVA Rating: 500 kVA

• Serial Number: 9937000616

• Catalog Number: 0075WP11K64A

• Date Manufactured: January 1999

• Frequency: 60 Hz

• Cooling Class: OA (Oil-Immersed, Self-Cooled)

• Temperature Rise: 65°C

Voltage Ratings Primary (High Voltage)

• 13200 GrdY / 7620 V o 13.2 kV grounded-wye distribution system o 7,620 V phase-to-neutral

Secondary (Low Voltage)

• 208Y/120 V o 208 V phase-to-phase o 120 V phase-to-neutral o 4-wire grounded wye

Impedance

• Z = 4.0%

This is slightly lower than the 4.5% impedance on the 300 kVA unit you showed earlier, resulting in a higher available fault current.

BIL Ratings

• HV BIL: 95 kV

• LV BIL: 30 kV

• Neutral BIL: 30 kV

Tap Changer Settings

Tap C is the nominal 13.2-kV setting.
