FOR <br />SUPERVISORY CONTROL AND DATA <br />ACQUISITION SYSTEM UPGRADES <br />education 18t <br />CITY MANAGER <br />RECOMMENDED ACTION <br />CLERK OF COUNCIL USE ONLY: <br />APPROVED <br />? As Recommended <br />? As Amended <br />? Ordinance on 1St Reading <br />? Ordinance on 2nd Reading <br />? Implementing Resolution <br />? Set Public Hearing For <br />CONTINUED TO <br />FILE NUMBER <br />Authorize the City Manager and the Clerk of the Council to execute the attached amendment to the <br />agreement with Transdyn Controls, Inc. to provide additional support services and equipment for the <br />Supervisory Control and Data Acquisition System (SCADA) for an additional not-to-exceed amount <br />of $20,000, subject to nonsubstantive changes approved by the City Manager and City Attorney. <br />DISCUSSION <br />The City's water production facilities are controlled by a Supervisory Control and Data Acquisition <br />(SCADA) System. The system utilizes remote programmable controllers at each water production <br />site and a central computer system located at the City Yard to remotely operate wells, pumps, and <br />reservoirs. Uninterrupted reliability and functionality of this system is required to maintain operation <br />of the water system. The existing system was installed by Transdyn Controls, Inc. in 1992 and was <br />most recently upgraded in 2006. <br />The current system provided by Transdyn has functioned since 1992 without failure. Due to recent <br />upgrades and additions to the water production system such as the West Station Upgrades, the <br />Water Resources Division has been experiencing communication problems with the SCADA system <br />that have not been resolved. Transdyn provided an estimate to troubleshoot the errors in the <br />system and to supply spare equipment radios for future hardware failures. <br />The City has an existing $25,000 agreement (N-2009-90-2) with Transdyn Controls, Inc. to provide <br />support services and equipment for unexpected problems occurring with the SCADA system, of <br />which $20,000 has been exhausted. The additional work will exceed the existing agreement and <br />therefore, staff is requesting an additional $20,000 for the extra support service and replacement <br />equipment. <br />25C-1
