2. Responses to Proposer Questions (Binding)

• Question 1: RFP indicates the “minimum font size should be 11 pt.” Will Metro Water allow smaller font used for tables, graphics, captions and headers/footers?

o Answer: Yes, Metro Water will allow smaller font used for tables, graphics, captions and headers/footers.

• Question 2: RFP indicates that “proposal must include the following information in the order listed below: 1. Transmittal Letter 2. Executive Summary 3. CM/GC Profile 4. Project Team Structure and Key Personnel 5. Relevant Project Experience 6. Project Approach 7. Appendix A:

Supporting Financial and Company Documentation 8. Appendix B: Resumes 9. Appendix C:

Comments on the form of Agreement (if any) 10. Appendix D: Pricing Information 11. Appendix E:

Letter of Commitment” However, page 17 of 251 section 6.3.10 Appendix D – Pricing Information states that the pricing information shall be provided by 5:00 PM seven days prior to the

Proposer’s interview date. When should pricing be submitted?

o Answer: Proposers shall not provide Appendix D - Pricing Information as part of their proposal due on September 22. If the Proposer is selected for an interview. An interview date shall be provided to the Proposer. The Proposer is then required to provide the

Appendix D – Pricing Information seven days prior to the interview date as indicated in

6.3.10.

• Question: 3 Within Stantec’s Basis of Design Report, the Process and Condition Assessment

Graphs are not visible. Was this intentional? If not, can the graphs be provided?

o Answer: This was intentional. The information was redacted as protected record.

• Question 4: RFP indicates that Electrical/instrumentation Key Firms and/or subcontractors are not to be included in the CM/GC’s Proposal. We are wanting clarification to ensure that this is intended to mean electrical subcontractor in any capacity not just for instrumentation. On past

CM/GCs it has been beneficial to have an electrician as part of the CM team early to help with long lead procurement items and work through constructability issues. We want to make sure we understand the intent with this exclusion.

o Answer: Metro Water clarifies that Electrical/Instrumentation is intended to mean electrical subcontractor in any capacity not just for instrumentation.

• Question 5: The RFP asks us to identify our Project Office Locations, “Identify where construction management Work will be performed during Phase I.” On page 4 of the RFP, Phase II construction services reads like the phase that will involve construction management. We want to make sure that the intention of this question was to identify the office location for construction management work during Phase I and not Phase II?

o Metro Water clarifies that the intention of the request for information on sub-bullet #2 under “Project Office Location” as follows: “Identify the location of offices that will support construction management Work performed during Phase II.

• Question 6: Self-performance basis of calculation Agreement 10.1.A states the Owner intends the

CM/GC to self-perform at least 40% of the total scope of Work on a monetary basis. RFP 6.3.3 identifies Electrical/Instrumentation, Integration/Programming, Public Engagement, and Survey as scopes the Owner will select following CM/GC selection. Will these Owner-selected scopes be included in the denominator when calculating the self-performance percentage? Relatedly, is the

40% figure a contractual requirement or a statement of Owner preference? The agreement says

Total, EI&C contractor would be contracted by the CMGC?

o Answer: Yes, the scopes mentioned will be included in the denominator when calculating the self-performance percentage. However, Owner will not select the scopes mentioned but will work in partnership with the CM/GC in the selection of said scopes.

o Answer: Yes, the 40% figure is a contractual requirement with the understanding that things may vary slightly based on actual bids once the CM/GC is on board and issuing bid backages.

o Answer: Yes, EI&C contractor would be contracted by CM/GC.

• Question 7: Article 6 - SC-6.03 H says that "all persons and entities performing any work on

Owner lands or Owner's interest in lands will provide performance and payment bonds". Does this apply only to the CMAR, or will all subcontractors on this project be required to provide performance and payment bonds for their portion of the work?

o The CMAR is only one expected to provide performance and payment bonds to the

Owner. This will cover the project for the full amount of the project, including work done by the subcontractors and materials provided by the suppliers. The contractor will choose who they want to provide them performance and payment bonds to protect them against failures, but that is their decision and they still have to provide the Owner what they originally signed up for.

• Question 8: The current agreement is silent on the limits of liability: Given the size and duration of the job, would the owner be willing to consider a total limitation of liability? This provides a clearer risk threshold to all parties involved with the work including those parties associated with insurance/bonding. We believe some level of limitation is beneficial to the owner on a job of this size from a cost savings perspective.

o Answer: The draft Contract Documents are as provided with the Request for

Proposals. As provided in Article 6.3.9 of the Request for Proposals, Proposers may include a detailed markup of the Agreement, including exhibits, of requested revisions by the Proposer, to be included in Appendix C. Any such Appendix C must comply with the

Request for Proposals and will be addressed as set out in the Request for Proposals.

• Question 9: Reference - General Conditions 6.01, 11.10, and Exhibit B - Bond Forms on page

218 of the RFP: Would the Owner consider accepting the current AIA payment and performance bond forms, or alternatively the standard EJCDC bond forms published independently of the

Contract Documents, in lieu of the required bond forms? Acceptance of nationally recognized industry-standard bond forms may increase the pool of willing sureties, enhance competition, and potentially reduce bonding costs to the Project while continuing to provide the Owner with robust payment and performance security from qualified sureties.

o Answer: The form of the bonds is as provided with the Request for Proposals. As provided in Article 6.3.9 of the Request for Proposals, Proposers may include a detailed markup of the Agreement, including exhibits, of requested revisions by the Proposer, to be included in Appendix C. Any such Appendix C must comply with the Request for

Proposals and will be addressed as set out in the Request for Proposals. That said, we do not anticipate accepting an alternative form of bonds, such as AIA or EJCDC.

• Question 10: Technical data availability during the proposal period Supplementary Conditions

5.03.G states that the CM/GC may examine the reports and drawings identified in SC-5.03.E and

SC-5.03.F, or request copies from the Owner’s Advisor at cost of reproduction or by secure electronic transmission. Will the Owner make these reports and drawings available to Proposers during the proposal period, and if so, what is the request procedure?

o Answer: No. This information will be provided to the successful CM/GC once a contract is in place.

• Question 11: Owner’s Advisor Agreement Article 2 states the Owner will retain an Owner’s

Advisor to act as Owner’s representative and construction contract administrator. Has the

Owner’s Advisor been selected, and if so, will the firm be identified prior to the proposal deadline?

o Answer: No. An Owner’s Advisor has not been selected. A firm will not be identified prior to proposal deadline.

3. Responses to Proposer Site Walk Questions – August 25, 2026

• Question: Would Metro Water inform the proposers when they receive reference forms from reference clients?

o Answer: Yes, Metro Water will endeavor to notify Proposers.

• Question: Will all 20 filters be needed for construction?

o Answer: Metro Water is currently evaluating whether the system requires all 20 filters or if it can operate efficiently with a reduced number (e.g., 14 filters).

• Question: How will the disinfection contact basin be used during construction?

o Answer: To be determined.

• Question: What is the status of the backfill stock piles on site?

o Answer: Site will be returned to original grade.

• Question: What are the biggest construction risks?

o Answer: MOPO and site access.

• Question: What are the biggest MOPO risks?

o Answer: In some cases, we won’t know what is in the ground until the trench is opened

up. Scheduling tie-ins.

• Question: How long can you go without treating water?

o Answer: Sill evaluating. Metro Water has shutdown LCWTP before but only for short periods of time. Point of the Mountain Plant (POMWTP) is typically a peaking plant which is run between April and November. Winter time (November to March) operation of

POMWTP is under evaluation.

• Question: How will chemical deliveries be routed during construction?

o Answer: Site is constrained. Chemical tanker trucks can turn around in some areas.

Proper, controlled routing will need to be a consideration.
