ADDENDUM # 2

Metal Clad Switchgear for Jessen and Willow Creek Substations

ITB # 25-151-G

This addendum modifies the bidding document(s) for work only to the extent indicated herein. All other areas not specifically mentioned or affected by this addendum shall remain in full force. This addendum shall be added as a part of the original bidding document and shall become part of the work required.

QUESTION & ANSWER

1. Please confirm if the RFP is for 2 lineups of indoor switchgear going into an existing enclosure.

Response: Yes, this RFP is for two (2) lineups of indoor switchgear going into two (2) different CMU block control houses which are existing structures. The lineups will be installed at different locations as noted in the Legal Advertisement.

2. Is EWEB able to provide a list of bidders who intent to bid for this RFP?

Response: We are provided a list of bidders from OregonBuys who have registered to be notified when we have bids with the same NIGP codes that the bidders are interested in, but the list does not indicate actual intention to bid.

3. What are the physical site requirements/description for both Jessen and Willow Creek substations to determine an accurate equipment lift plan ?

Response: Both Jessen and Willow Creek are electric substations that have CMU block constructed control houses. The access for each set of switchgear into the control house will be via a roll up door with a 9’-4” x 9’-4” opening (approximate). This contract does not include any field services (including offloading or field assembly) so EWEB will handle this work as long as the switchgear shipping section can fit through the roll up door.

4. Can you provide a list of approved crane contractors that are approved by EWEB currently?

Response: Oldham Crane Services and Ness Campbell Crane Services

5. Is Contractor to do any cabling? EWEB specifically states the power transformer is not in scope but there is a detailed description of the connections.

Response: EWEB will be responsible for bringing power cables to the switchgear and making connections.

6. Do we need to include a quote for field services?

Rev 4-21-20

Response: No field services are required for this RFP. The specification has provision for including field services and a Field Engineer but we are not using those provisions for this RFP. Again, this contract does not include any field services (including offloading or field assembly) so EWEB will handle this work as long as the switchgear shipping section can fit through the roll up door.

7. The enclosure does not appear to be defined- there is no specification regarding the building or site plan to provide guidance as to foundation, dimensions, environmental, building codes.

Response: The enclosure will be a block building to house the switchgear and EWEB-owned control panels. Exhibit #1 is provided and shows a building floor plan for Jessen Substation with the planned layout.

8. There are lots of control and protection drawings included in the bid documents but where are the electrical single line drawings? Are we supposed to assume that Jessen and Willow Creek are identical?

Response: Exhibit #2 has been added which shows the protection and control single line drawing for Jessen Substation. EWEB is looking for two identical designs and the electrical requirements of the switchgear are identical for both stations.

CLOSING DATE AND TIME: SEPTEMBER 24, 2025; 2:00 PM
