SOW-2020 Building 402 Utility Reroute.docx

Statement of Work Building 402 transformer replacement and main feed reroute USDA, Ames, IA 7-9-2020

Project Requirements:

Background:

During the deconstruction of Building 400, one of the two (2) 13.8kV power feeds that had previously fed Building 400 was redirected into the old, existing 500kVA transformer that feeds Building 402. The other feed, Dayton Avenue, was removed. The transformer at Building 402 shares the 13th Street feeder with the existing switchgear located to the north and east of Building 402. This feeder originates from the city feed switch located on the outside of the south perimeter fencing, just to the north of 13th Street and then terminates at the existing switchgear located to the northeast of Building 402 across the road. This system has become a concern due to the fact that if the existing 500kVA transformer were to fail, we would lose all of the south campus due to how the feed is wired.

Scope:

The scope of work for this project is as follows:

1. Outages will need to be scheduled before any of the following steps are performed! Outages will need to be scheduled at least 2 weeks in advance to allow for notification of affected personnel. Building 402 has electric heating. Winter shutdowns will need to be scheduled when the temperature is above freezing and kept to a minimum. If needed, power outages could be scheduled after hours or on weekends.

2. Remove the existing 13th Street feed (13.8kV) feed from the existing Building 402 transformer back to MH-402.

3. Re-route the 13.8kV feed from MH-402 to the existing switchgear north of 402.

4. Connect the existing 13th Street feed from MH-402 to the existing main feed switch in the switchgear.

5. Using the spare switch in the switchgear that formerly fed Building B1 and B2, re-feed Building 402 transformer.

6. Remove old, existing 500kVA transformer.

7. Once the existing 500kVA transformer is removed, demolish existing concrete pad and replace with a new concrete pad with a spill containment basin. See attached detail labeled “Transformer Details”.

8. Replace the existing 500 kVA transformer with a new, outdoor-rated, 3 phase, 60 Hz, 500 kVA transformer with a kV class of 15kV. Transformer shall have a dead front, cooling class of KNAN, 95kV BIL, and a temperature rise of 65 degrees average. New transformer shall meet the DOE 2016 standards for efficiency.

9. Contractor will re-install all equipment and wiring associated with the Veris Industries, Hawkeye 8100 power monitoring meter located inside Building 402 and inside the new 500kVA transformer. This also includes proper disposal of old transformer in compliance with Federal, State, and Local codes.
