R5. Please replace General Instructions for Vendors, Terms and Conditions with the revised version included in this addendum.

II. Questions:

Q1. Regarding Section 01 10000, Summary of Work, Part 1, 1.2, C, 1 and 2, it states “1.

Installation of valves may happen in phases in order not to disrupt the Owner’s operations.

2. Startup of the valves may need to happen in multiple visits depending on the construction phasing.” For the purpose of estimating costs, is there any way the number of visits can be capped or after a certain number of site visits, a daily adder for additional visits can be included in the contract?

A1. DWR’s installation contractor will provide start-up services through a separate arrangement between the installation contractor and the awarded supplier.

Q2. Are expansion joints or other valves needed for this project?

A2. No, this project does not require expansion joints or other valves.

Q3. Are there any special requirements, such as BABA or AIS?

A3. There are no special requirements.

Q4. It states that “Simple O-Ring shaft seals will not be accepted”. SWC valves are bottom buffered valves and the shafts in these units are sealed with O-Rings. Please provide clarification about this requirement and whether these valves will be acceptable.

A4. O-Rings will be accepted. See revised specification Section 40 0565.23, 2.2, J.

BL009-26 Page 2

Q5. Please consider adding Pratt/CCNE to the approved manufacturers list in section 40 0565.23, 2.2.B.

A5. Pratt/CCNE has been added to the approved manufaturers list. See revised specification Section 40 0565.23, 2.2, B.

Q7. Has there been consideration for the dimensions of the bottom buffer needed for the new valves being supplied? They require a considerable amount of clearance underneath the valve. The original valves supplied had cushioning devices on the side in a 2-stage or 3-stage arrangement. Please clarify lay length and bottom clearance.

A7. Suppliers are responsible for verifying clearances in existing check valve locations. A second pre-bid conference has been scheduled to provide that opportunity. Please see Revision R1.

Q8. Please provide clarification about the bond requirements for this solicitation.

A8. There are no bond requirements for this solicitation.

Q9. If this solicitation is being awarded by line-item, please clarify how start-up services should be listed.
