Webb, Public Works Director - 949-644-3311, dawebb@newportbeachca.gov PREPARED BY: Ben Davis, Associate Civil Engineer, bdavis@newportbeachca.gov PHONE: 949-644-3317 TITLE: Approval of Amendment No. 2 to Professional Services Agreement with Stantec Consulting Services, Inc. for Big Canyon Reservoir Flow Metering Vault and Treatment Improvements (Project No. 16W13) ABSTRACT: On July 28, 2015, the City entered into a Professional Services Agreement with Stantec Consulting Services, Inc. for engineering services to design flow metering and treatment improvements at Big Canyon Reservoir (BCR). As part of this design effort, additional reservoir improvements and construction support services are required for the Big Canyon Reservoir Flow Metering Vault and Treatment Improvement project. RECOMMENDATION: a) Determine that the action is exempt from the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) and 15060(c)(3) of the CEQA Guidelines because it will not result in a physical change to the environment, directly or indirectly; and b) Approve Amendment No. 2 to the current Professional Services Agreement with Stantec Consulting Services, Inc. to add $42,452.00 to the agreement to fund necessary design and construction support services, and authorize the Mayor and City Clerk to execute Amendment No. 2 of the Agreement. FUNDING REQUIREMENTS: The current adopted budget includes sufficient funding for this contract. It will be expensed to the Capital Improvements Program budget in the Public Works Department, 70101-980000-16W13. Approval of Amendment No. 2 to Professional Services Agreement with Stantec Consulting Services, Inc. for Big Canyon Reservoir Flow Metering Vault and Treatment Improvements (Project No. 16W13) September 12, 2017 Page 2 DISCUSSION: The City entered into a Professional Services Agreement with Stantec on July 28, 2015 to provide design services for BCR Flow Metering Vault and Treatment Improvements project. The initial scope of services in the agreement included design of a flow metering vault and water treatment improvements. During the design process, the consultant scope was expanded at the request of Utility staff to include a crane replacement and lighting improvements at BCR, as well as Computational Fluid Dynamics (CFD) analysis modeling of the outflowing reservoir waters. As a result of the CFD modeling, the design was expanded to include two mixing elements to improve overall drinking water quality. These additional items were considered critical at the time to keep the design process moving forward; however, the initial work scope did not include the crane replacement, CFD modeling, and design of two mixing elements. Incorporation of these items has increased the consultant design cost and will require additional construction oversite and assistance services from the consultant. This amendment will provide the necessary contract funding to cover these expanded necessary services. ENVIRONMENTAL REVIEW: Staff recommends the City Council find this action is not subject to the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential for resulting in physical change to the environment, directly or indirectly. NOTICING: The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).

(Stantec) to develop improvements at the Big Canyon Reservoir control building to eliminate the treatment issues related to the inability of meter flows on the Zone 2 pipeline and the inadequate chemical mixing downstream of the existing chemical dosing point on the effluent pipeline. The design documents for the Big Canyon Flow Metering Vault and Treatment Improvements have been completed. The project bid on July 11, 2017 and was awarded to the lowest bidder at the August 8, 2017 City Council meeting. Stantec's Professional Services Agreement with the City included limited construction engineering support when requested by the City. However, the budget associated with this work was reallocated to Computational Fluid Dynamics (CFD) analysis. For the CFD analysis, we did not know what type of mixing device should be used for this application when we prepared our proposal. Several of the available options would not have required CFD modeling. When first discussing the application with Tim Berschauer from Charles Crowley, we all had believed that BETE would prove out their system at no cost to the City. It was not until we had several workshops with Tim that we learned that BETE would charge us to prove out their product. Lastly, it should be noted that the RFP did not discuss CFD analysis. As such, neither the City's nor our initial budget included CFD analysis. With hindsight, it was critical that the CFD modeling was performed. We learned that the mixing system will work for flows below the effective range of the Ultratab, but not for the entire range of flows. Two systems were required to provide adequate chemical mixing over the entire operating range. In addition to restoring the construction engineering support budget, the scope of work is proposed to be expanded due to other needed improvements that were added to the project. Design with community in mind 11-8 (3 August 18, 2017 Ben Davis, PE Page 2 of 4 Reference: Request for Change Order No. 2 for Big Canyon Reservoir Flow Metering Vault and Treatment Improvements During the final design phase, the design team determined that it would be cost-effective to have the contractor upgrade several other facilities while mobilized to the site. These additional facilities include the following items: • Installation of a new crane system in the first floor of the control building, • Replacement of the removable grate frame between the first floor and the basement of the control building, • A new lighting system for the basement of the control building, and • A new driveway approach to provide vehicular access to the metering vault. The following scope of work and attached fee proposal include the construction engineering support services that were previously removed from our contract and engineering services to support construction of the above bulleted additional facilities. Scope of Work for Services covered by Amendment No. Two: TASK 5: CONSTRUCTION ENGINEERING SUPPORT A. Prepare Conformed Contract Documents. Stantec will incorporate all changes from Addendum No. 2 into the Contract Plans and Specifications. Deliverables will include electronic pdf file of plans and specifications. B.

Stantec will budget to attend a total of seven (7) construction related meetings. Our electrical engineer, Linkture, will attend two (2) meetings. One (1) meeting will be during construction and one (1) meeting will at start-up to provide their punch list. C. Stantec will review shop drawings submittals to include the following budgeted number of submittals: Design with community in mind 11-9 L August 18, 2017 Ben Davis, PE Page 3 of 4 Reference: Request for Change Order No. 2 for Big Canyon Reservoir Flow Metering Vault and Treatment Improvements 1.
