WEST YOST <br />ASSOCIATES <br />Cantultmg Engu.em <br />October 25, 2017 <br />SENT VIA: EMAIL <br />Ms. Robin Kim <br />Management Analyst <br />Public Works Services Department <br />City of Redwood City <br />1400 Broadway St. <br />Redwood City, CA 94063-2505 <br />SUBJECT: SCADA Communications Network Design and PLC Upgrades <br />Dear Ms. Kim: <br />West Yost is pleased to submit this proposal for the SCADA Communications Network Design <br />and PLC Upgrades project (Project) for the City of Redwood. Our team has demonstrated <br />successful completion of similar projects with a focus on secure network design, and <br />implementation based on current industrial control system cyber security standards including NIST <br />800-82 and the Cyber Security Framework (CSF). Our key staff maintain multiple industry <br />recognized cybersecurity certifications including CISSP, CCNA and GPEN as well as registration <br />as Professional Engineers in the state of California. <br />PROJECT UNDERSTANDING <br />Our team understands the drivers and timeframe for this project including the current challenges <br />with limited radio frequencies available to the City as well as the cybersecurity challenges facing <br />critical infrastructure in general. We understand the need to evaluate the existing radio <br />infrastructure to help the City evaluate options including licensing of additional radio frequencies. <br />We understand the City will need to upgrade much of the existing control systems equipment, <br />including obsolete Allen Bradley MicroLogix controllers, throughout the City. We understand that <br />the City plans to continue to use Wonderware software and Allen Bradley controllers. <br />We understand the City's planned schedule for implementation of the upgrades to the network is <br />within 2 years and the control system replacement will be within 3 years. <br />2020 Research Park Drive.
