REQUESTS FOR INFORMATION:

1. Who is responisble for the transformer disposal?

Answer: The contractor is responsible for the transformer disposal. Transformers do not contain PCBs.

2. Can wires be crimped rather than spliced?

Answer: No, splice kits are specified; compression kits will not be accepted.

3. Which connectors (feeders) are to remain and which are to be replaced?

Answer: The connector from project office to disconnect at base of dam remains. The connector from disconnect to gatehouse will be replaced.

4. Who originally pulled the feed from the disconnect to the gatehouse?

Answer: The US Army Corps of Engineers did.

5. The disconnect remains at the pole at the base of the dam?

Answer: Yes, it remains.

6. What is the size of the feed from the Project Office to the base of the dam?

Answer: Feed is 3 phase, 480V, ungrounded.

7. Are any new grounding rods to be added at the base of the dam at the disconnect?

Answer: No.

8. The bonding at the pole of the base of the dam is only to the lightning arrestors and doesn’t include the disconnect. Will the disconnect need to be bonded?

Answer: Yes, the contractor will need to bond the disconnect.

9. Is an equipment grounding conductor required?

Answer: Yes, the contractor will need to run an equipment grounding conductor from the disconnect at the base of the dam to the gatehouse.

10. Will additional grounding be required at the gatehouse?

Answer: Yes, an additional ground rod will be installed at the base of the gatehouse.

11. How do we access the base of the gatehouse?

Answer: Access for vehicles to the base of the gatehouse will be provided by the US Army Corps of Engineers.
