HomeMy WebLinkAbout#06 - SCADA AgreementDATE: 2/2/2022 CONSENT ITEM #: TO: City Council FROM: Marty Powers, Public Works Director AGENDA ITEM: SCADA System Service Agreement REVIEWED BY: Kristina Handt, City Administrator BACKGROUND: Starting in 2016 the City of Lake Elmo has entered into a service agreement with Telemetry & Process Control to perform preventative and corrective maintenance of the computer system and controls that operate the municipal water and sewage pumping systems. The aforementioned contract expires on January 22, 2022. After reviewing the needed service and the growth to the City’s SCADA system, (new water tower, well 5 and new lift stations on 32nd St and in tapestry), I have found necessary benefits from this contract. ISSUE BEFORE COUNCIL: Does the City Council want to enter into a two-year maintenance contract with TPC for the water and wastewater SCADA System? PROPOSAL DETAILS/ANALYSIS: Entering into the proposed service agreement helps ensure that SCADA System functions will be maintained to operate as designed. In addition, this contract reduces hourly service & support rates and guarantees phone support and on-site services 24 hours a day. TPC is the designer of the current SCADA System and has been providing support for the operation of city wells, water towers and lift stations for years. With the growth of the city’s infrastructure, service of this type is crucial in order to provide uninterrupted water and sewer services to Lake Elmo residents. FISCAL IMPACT: $28,240.08 per year paid monthly out of Water and Sewer Contract Services OPTIONS: • Approve SCADA System Service Agreement • Deny SCADA system Service Agreement RECOMMENDATION: If removed from consent agenda “Motion to approve a two year SCADA System Service Agreement with Telemetry & Process Controls” ATTACHMENTS: • Service Agreement Proposal January 7, 2022 City of Lake Elmo - Public Works Department 3800 Laverne Avenue Lake Elmo, MN 55042 Attention: Mr. Marty Powers - Public Works Director mpowers@lakeelmo.org 651-747-3941 Thank you for the opportunity to provide the following proposal for a new annual SCADA System maintenance agreement; as the existing two-year agreement ends on January 22, 2022. City of Lake Elmo, MN Public Works Department Maintenance Agreement Proposal #220107DG - for the - Potable Water Distribution / Treatment & Wastewater Collection Supervisory Control And Data Acquisition (SCADA) System We highly recommend that the City of Lake Elmo Public Works Department enter into a new annual SCADA System maintenance agreement with TPC, Inc. The proposed agreement includes preventative and corrective maintenance services*. Listed below are some important reasons why the agreement will be of benefit to the City: • Reduced hourly service & support rates will apply. • A guaranteed response time for phone support and “on-site” services that will be negotiated based upon your needs and the requirements of the system. Customers who are not under contract will continue to receive our technical service support; however, the response time is not guaranteed. • It has been proven that SCADA systems that are properly maintained operate more efficiently with much less downtime and potential associated overtime expense. • Systems that are routinely maintained typically last longer than systems without preventative maintenance services. TPC’s annual maintenance agreement includes three major service components: • The first of these components is the provision for a complete “on-site” system check out. We recommend that this preventative maintenance task be done once a year. • The second component of our agreement consists of “on-site” corrective maintenance; to repair and/or replace failed hardware components or to troubleshoot and rectify system operational or data communication issues. • The third component is the provision for an estimated number of TPC “in-house” tech service and phone support hours. The following services are typically provided as part of a complete “on-site” system check out: • Check each sites PLC processor for proper running condition. • Verify each digital input and digital output. • Verify the calibration of each analog input and recalibrate if necessary. • Check all PLC power supplies for proper voltages and replace if necessary. • Examine all local hardware (i.e. switches, displays, lights, relays, etc.) to verify their proper operating condition. • Check all local D.C. power supplies; to verify output voltages and replace if necessary. • Check each Uninterruptible Power Supply (UPS) to verify proper operation and the status of the battery in each unit. Recommend replacement, as necessary. • Verify and tighten all terminals, so there are no loose wire connections. • Verify proper RF communication at all SCADA system equipment locations. • Verify the proper operation of the HMI software programs and provide the City with recommended HMI package updates when they become available. • Run tests on the SCADA system printer(s); verify proper communications with the PC. • Check all spare parts, verify proper working condition, and recommend replacement of bad parts. • Retrain existing personnel and train new City personnel who interface with the SCADA system as needed. TPC is certainly aware of and acknowledges the City’s economic constraints. For this reason, we stress the importance in considering the short and long-term savings that can be realized by having this annual service agreement in place. Based upon the projected number of TPC service tech hours required to implement one complete, documented, “on-site”, preventative maintenance, system check of all SCADA system sites and provide a year of TPC service tech support services, this City of Lake Elmo Water Distribution / Treatment and Wastewater Collection SCADA System – Annual Service Agreement Contract includes two-hundred, fifty (250) hours of TPC technical Service Engineer’s time per year for “on-site” and “in-house” support services, travel time and mileage. Replacement parts are not included in this service agreement. TPC’s monthly charge for this service will be $2,368.34; resulting in a total annual amount of $28,420.08. TPC, Inc. is willing to extend this annual contract rate for an additional year; if that is part of the signed agreement now. Lake Elmo service requests of TPC that are made outside of normal weekday, non-holiday, working hours will be subject to the following “Overtime” labor surcharges: • $57 per hour, for weekday, non-holiday, service requests, one hour minimum overtime charge • $114 per hour, for weekend and holiday service requests, one hour minimum overtime charge • These “Overtime” labor surcharges are in addition to the $2,368.34 monthly service charge described above. *Preventive maintenance, as the term is used herein, has the following meanings: 1. The care and servicing by personnel for the purpose of maintaining the SCADA system hardware & software in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects. 2. Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring. The primary goal of this maintenance is to avoid or mitigate the consequences of equipment failure. This may be by preventing the failure before it occurs; which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they fail. Preventive maintenance activities include partial or complete overhauls at specified periods. In addition, our service engineers can record equipment deterioration, so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs. In summary: ➢ Preventive maintenance is conducted to keep the SCADA system equipment working and to extend the life of the equipment. ➢ Corrective maintenance, sometimes called "repair", is conducted to get the SCADA system equipment working again. ➢ We appreciate the opportunity to present this proposal to the City of Lake Elmo Public Works Department.
