Addendum 1 Contract 22-124-G Currin CH.pdf

ADDENDUM # 1 June 7, 2022

Title: Control House for Currin Substation

RFP # 22-124-G

This addendum adds additional information to the original ITB document.

QUESTION & ANSWER:

Q1a. For drawings D-37835-75A and D-37835-76, we do not see the bill of materials. Can you please provide?

Q1b. There are a total of 11 panels to be quoted for drawings D-37835-75A and D-37835-76, however we see only the RTU Drawing D-37835-192. We are asking for the elevations and BOM’s for panels A2, A3, A4, A6, A7, B1, B2, B3, B4, and B5.

A1. Please refer to Item A, attached. The BOM is not 100% construction-ready but will be sufficient for bidding purposes.

Q2. The plan view drawing (052722) is calling out for the building to be split in 3 sections. Are there any site constraints for access that are driving the building to be split in 3 sections?

A2. There are no site constraints requiring the 3 shipping sections. Drawings of Currin’s layout (D-37834-1) and access road (D-37834-5) have are attached here as Item B so the bidder can ensure their proposed solution will not have access or delivery issues.

Q3. The plan view drawing (052722) is calling out for the building to be split in 3 sections. Would EWEB accept a proposal to optimize the design for a [2] piece building divided down the middle?

A3. This is acceptable as long as the general dimensions and layout are not affected. Slight movement of some items is expected and acceptable, but changes that could reduce the work area for switchgear breakers or break the general “flow” of the suggested layout will be reflected in lower scores for “Product Compliance”.

Q4. We are requesting the bid due date to be extended to 7-6-22.

A4. Unfortunately, we cannot extend without compromising the construction timeline.

Q5. It looks like there are missing drawings for the relay panels. Can you please provide all drawings, including the following:

EC3-5.0509, EC3-5.0513, EC3-5.0514, EC3-5.0504, EC3-5.05050, EC3-5.0507, EC3-5.0508, ED3-

5.1010, ED3-5.1005, EC3-5.0104, EC3-5.0525

A5. The following standards listed on EWEB standard ED3-3.0500B (relay test switch nameplates) are not required for this bid:

• EC3-5.0509 (SEL-311C, Single Breaker)

• EC3-5.1006 (SEL-387L, Single Breaker)

• EC3-5.0513 (SEL-311L, Single Breaker)

• EC3-5.0514 (SEL-311L, Two Breaker)

• EC3-5.0504 (SEL-421, Single Breaker)

• EC3-5.0505 (SEL-421, Two Breaker)

• EC3-5.0507 (SEL-411L, Single Breaker)

• EC3.5.0508 (SEL-411L, Two Breaker)

• ED3-5.1010 (SEL-387, Bus)

• EC3-5.0104 (BE1-851)

• EC3-5.0525 (SEL-787, Breaker Fail)

The above relays are either not used for this project or the design of these relays will be provided by EWEB to the successful bidder, including full nameplate details.

The only standards needed for the design of the switchgear are:

• EC3-7.0130 (Panel Meter)

• ED3-5.1005 (SEL-387, XFMR & Bus)

• EC3-5.0522 (SEL-751, Main Breaker)

• EC3-5.0523 (SEL-751, Bus Tie Breaker)

• EC3-5.0521 (SEL-751, Feeder Breaker)

All of the above standards were provided with the RFP documents.

CLOSING DATE AND TIME

June 28, 2022. Remains unchanged.

This addendum constitutes a MATERIAL CHANGE to the Request for Proposals.
