REQUEST FOR COUNCIL ACTION CITY COUNCIL MEETING DATE: SEPTEMBER 18, 2018 TITLE: APPROVE AGREEMENT WITH DUDEK FOR CONSULTING WATER ENGINEERING SERVICES FOR CENTENNIAL LAKE RENOVATION (PROJECT NO. 18-2681) (STRATEGIC PLAN NO. 6, 1G) RECOMMENDED ACTION CLERK OF COUNCIL USE ONLY: APPROVED ❑ As Recommended ❑ As Amended ❑ Ordinance on 1$' Reading ❑ Ordinance on 2nd Reading ❑ Implementing Resolution ❑ Set Public Hearing For CONTINUED TO FILE NUMBER Authorize the City Manager and Clerk of the Council to execute an agreement with Dudek for a two- year term beginning September 18, 2018, and expiring on September 17, 2020, with two one-year renewal options exercisable by the City Manager and the City Attorney, to provide consulting water engineering design services for Centennial Lake Renovation, in the total amount not to exceed $217,726, which includes a five percent contingency in the amount of $10,368, subject to nonsubstantive changes approved by the City Manager and City Attorney. Centennial Lake is a man-made 10 -acre water feature at Centennial Park (Exhibit 1). Since its construction in 1978, no major renovations have been made. Existing operational equipment and facilities have reached the limit of their design life and as a result, water quality has significantly declined. In 2017 a comprehensive assessment and study of the lake was conducted. Data collection efforts included water quality sampling, lake liner sampling, assessment of lake environs and lake/park user behavior, maintenance personnel interviews, and equipment inspections. These findings led to preparation of the "Centennial Lake Rehabilitation Project Manual," which contains the remediation plan that will provide the basis for the Contract Documents. In April 2018, the Public Works Agency released a Request for Proposals (RFP) via PlanetBids and the City website inviting qualified firms to submit proposals for engineering services. PlanetBids notified 375 firms. Nine firms downloaded the RFP and two firms — PACE Engineering and Dudek — attended the pre -proposal submittal meeting. One proposal was received from Dudek; PACE subsequently sent written notification stating they made a determination not to submit. The proposal from Dudek was evaluated by staff from the PWA Design Engineering and Water Resources Divisions, along with the Parks, Recreation and Community Services Agency. Upon evaluation of the firm and key team member experience, understanding of need, relevant project experience, and appropriateness of proposed fee, staff recommends award of the design contract to Dudek. Based on the schedule of rates and fees, which is incorporated into the contract (Exhibit 2), the proposed fee in an amount not to exceed $207,358 is recommended for City Council approval. Staff 25E-1
