OTETRA TECH November 17, 2022 Armando Fernandez, PE Project Manager City of Santa Ana, Public Works Agency 220 S. Daisy Ave., M-85 Santa Ana, CA 92703 Reference: Request for Proposals for On -Call Engineering Design Services for PEAS Treatment Systems, RFP No. 22-133 Dear Mr. Fernandez, Tetra Tech is very pleased to provide our proposal for your On -Call Engineering Design Services for PFAS Treatment Systems. In the last four years Tetra Tech has been performing similar PFAS engineering services for public agencies in both Orange and Los Angeles Counties. We are one of only a few firms that have completed the design of six PFAS projects, including the first operating project in Orange County and the largest PFAS Ion Exchange (IX) project in the United States. The Team we are proposing has extensive, local experience developed over the last five years on PFAS projects. Steve Tedesco, PE, our Project Manager has directed each of these projects making sure the Team provides high -quality engineering while meeting project budgets and schedule. Over the last four years our team has developed a large data base of costs on completed projects that can be used to provide cost certainty in this time of rapidly changing prices. To accelerate the schedule and reduce costs, Tetra Tech has developed an implementation strategy that will provide the City of Santa Ana (City) with two separate design teams working under the direction of a single Project Manager and reviewed by a single QA/QC Manager for consistency. Each team includes a Task Leader and key design team members in the following engineering disciplines: ■ Civil ■ Process/Mechanical ■ Structural ■ Electrical, Instrumentation & Control ■ Water Quality ■ 3❑ CAD❑ Each team will also have access to an additional 20 engineers and production staff to use as needed to further accelerate the schedule. Tetra Tech is committing 35 full-time staff with over 90% of them located in Southern California. Our only sub -consultants on the project consist of Leighton Associates for Geotechnical Engineering and Metz Surveying for Site Topographic Survey. We have also included Alan Ludwig of Pascal & Ludwig to assist with cost estimating and constructability review. Having a local contractor who has built numerous IX plants brings additional credibility to a project. 17885 Von Karman Avenue, SLIICE' 540.
