Agreements for On -Call Engineering Services <br />April 4, 2023 <br />Page 2 <br />For the wells in which PFAS has been detected but do not exceed the state Response <br />Levels, and therefore do not meet the requirements for OCWD agreement, the City has <br />taken a conservative approach and taken the wells offline. In order to bring the wells <br />back online, the City will need to design and construct PFAS treatment facilities at each <br />affected well site. <br />Water Resources is seeking engineering consultant firms to provide design services for <br />PFAS ion exchange treatment facilities in order to optimize treatment at future sites <br />impacted by the constituent of concern. It is imperative that the City prioritizes water <br />treatment to ensure residents can be guaranteed the highest quality of potable drinking <br />water. <br />On October 3, 2022, the Public Works Agency released Request for Proposals (RFP) <br />No. 22-133, by which it sought the services of qualified consulting firms to provide <br />engineering design services for PFAS treatment systems. The RFP was advertised on <br />PlanetBids, and proposals were received electronically via PlanetBids on November 17, <br />2022. The City notified a total of 112 regional vendors via PlanetBids, with 40 vendors <br />downloading bidding documents. Three proposals were received and evaluated by a <br />selection committee. Based on criteria outlined in the RFP, the following summarizes <br />the responding firms and their ranking: <br />Firm <br />City <br />Rank <br />Tetra Tech, Inc. <br />Irvine <br />1 <br />Stantec Consulting Services, Inc. <br />Irvine <br />2 <br />EEC Environmental <br />Orange <br />3 <br />Staff recommends awarding agreements to Tetra Tech, Inc., Stantec Consulting <br />Services, Inc., and EEC Environmental to provide engineering services on an as - <br />needed basis (Exhibits 1-3). Their proposals demonstrated the firms have the <br />necessary capacity and expertise to complete the required services. The firms' rates are <br />reasonable and within industry standard, the teams' qualifications are appropriate, and <br />the proposals were determined to provide the best value for the City. All firms selected <br />for this award are currently under agreement with the City for other consulting services <br />and have performed quality work for the City. <br />FISCAL IMPACT <br />Funding is available in the FY 2022-23 budget and funding for subsequent fiscal years <br />will be included in the proposed budgets for City Council consideration.
