BACKGROUND: Through the course of the development and installation of the new SCADA System, several issues have occurred that necessitate a change order to the project The two major items are 1) the addition of a new alarm system design to replace the existing alarm system; and 2) modifications to the City's radio system to maintain a "tone alert" for entry into the City's wells, towers and hft stations that are broadcast on the City's radio channel. The first item to add anew alarm system is a modification that has been requested by City staff. As outlined in the attached letter from Paul Kaeding, the new alarm system \\all allow quick and efficient modifications to the "dial out" numbers from a work station at Pubhc Works versus reprogramming of the "dial out" numbers at the master location at Well No 7 next to the Chippendale Tower The second major item is necessary to modify and maintain a "tone alert" system as part of the City's radio system. Again, as outhned in the letter from Paul Kaeding, the "tone alert" system is routed through the wood shop, Well No 3 and City Hall. Modificauons to the system will eliminate the route to Well No 3, a low production well that is planned to be taken off -line in the future. Following is a summary of the proposed contract cost modifications: Change Order #2 also includes an extension of the completion date for the project from July 31, 2005 to September 30, 2005. SUMMARY: Staff is requesting Council approval of Change Order #2 for the 2004 SCADA System, City Project #377.

This change order request includes six items related to the project. An explanation of the items follows: During the design of the project, a path study was conducted to predict if the projected radio paths from the vanous sites to the master location would be successful. The study is "general" in nature because the radios are not permanently mounted, and the antenna at each location is approximated rather than being permanently mounted at its final location. The results are interpolated, and a prediction of the signal strength is generated. Actual results are generally better than predicted, since the final height of the antenna is greater than dunng the study. At three lift station sites in the northwest part of the community, the actual signal strength is marginal, and occasional "loss of signal" conditions have been encountered. This condition is expected to deteriorate as trees grow and additional attenuation from the foliage is encountered. The condition is expected to be better in the winter when the foliage is off the trees. To improve the situation, the signals from the lift stations have been transferred to the Connemara Tower and "repeated" from that tower to the system master. To improve the reception at the Connemara Tower, the antenna was changed from a directional antenna to an onmi- directional antenna, and the antenna was raised. This resulted in additional costs related to the antenna and mounting the antenna higher on the tower. An increase in the contract amount of $1,650 will be encountered, and approval of this change order item is recommended. Programming changes will be handled via a "call back" allowance provided in the specifications. The new SCADA system includes computer workstations at the Public Works Building, as is the case with the existing system. The new system will include two dialers at the master location. One of the dialers is programmed to alert operators to alarm conditions The second dialer is used to contact law enforcement personnel ifunauthonzed entry is attempted. (Please note that since this document is in the public domain, we are avoiding being more specific, but will provide those details if you or the Council are interested.) The major advantage of this configuration is that it is the most reliable of several options. A disadvantage is that it requires that operators access the alarm system components at the CITY OF ROSEMOUNT Attn: Mr. Andrew Brotzler, City Engineer July 27, 2005 Page 2 master location. The operators have requested an alarm system that allows configuration of the "dial out" numbers from one workstation. This alarm system is a software program that resides in the workstation and will not work if a workstation "crashes so the dialers are also recommended. However, the ability to configure and change telephone numbers and disable alarm points for daytime operation is easier with the software -based system than the dialer system. The cost of the software -based alarm system is $14,296. The workstation screens have been revised from the format originally used in order to "standardize" on terminology for the water distnbution, wastewater and stormwater pumping stations. This "standardization" will result in software changes and additional costs of $3,000. These items are recommended. It was discovered during construction that a "tone alert" system was installed many years ago on the Public Works radio system. The location of the components of this "tone alert" system was not known. After a substantial amount of research, it was discovered that the "tone alert" system is connected to the radio system at well #3 The wiring then goes to the wood shop, which was formerly the Public Works office, and then to City Hall where the tone alert system is located. The existing components indicated a company in Webster, Minnesota, constructed the system. A search of the files at Public Works, as well as checking telephone listings and reverse telephone listings, failed to turn up any schematic diagrams, parts lists, or related information on the system or the person who ongmally built the system estimated to be some 20 years ago. The manufacturer of the City Public Works radio and communication system was contacted. They offer a two tone alert system that can be added to the radio system. The advantages include the ability to remove components from well #3, which is a low production well; and the ability to obtain components from the manufacturer of the radio /communication system, so schematics and parts can be obtained from a single source. However, this will require modifications to the proposed SCADA system so a common alarm can be generated. The SCADA project will realize additional costs of $1,500 for work by US Filter field personnel in tracmg the wiring from the ongmal SCADA panel in wellhouse #3 to the existing wood shop. A change order amount of $5,900 is proposed for system software changes to consolidate the alarm points and generate a single tone output. The specifications included an allowance for computer hardware that was available at the time the project was bid and constructed. The fourth item is a reconciliation of the actual cost for the computer hardware and the allowance. This will result in a deduct change order amount of $14,739.61. The construction of the new SCADA project is commencing at a satisfactory rate. However, conversion of lift stations and water system facilities to the new SCADA system has been delayed pending resolution of the alarm functions identified in this memo, particularly the tone alert features. As a result, US Filter, the contractor for the SCADA system, has been directed to not convert the City system from the old monitoring system to the new SCADA system until the tone system is also converted. This will result in a delay of the completion time of the project. A change order item extending the completion of the project from July 31, 2005 to September 30, 2005 is requested and recommended.

Radio Tone E -Mail: paulk@kaeding.com 1 Project: Rosemount, MN, 503812 CHANGE ORDER Quotation Number: 07/25/05 CIO #7 Addition of Radio Tone logic for alarms on the Rosemount SCADA System. A spare relay at the Chippendale/Well #7 panel will be used and interfaced with a third -party device (supplied by the City) that provides a tone on the City Wide Radio System. A screen will be added to the HMI system that allows the radio tone to be enabled/disabled and provides a configurable time period for a delay between the tones, i.e. 5 minutes. The screen will be added in a location on the HMI system that is only accessible at a Manager level login. There will be an indication of the Radio Tone status added to the network screen, so all Users can view if the tone is enabled or disabled. In addition, an alarm event will be logged to the HMI system when the radio tone is disabled. The PLC program at Chippendale/Well #7 will be modified to output when any alarm Is received on the SCADA System. The radio tone output will function based on the configured time period delay and if the tone is enabled on the SCADA screen. The output will continue until the alarm condition has cleared regardless if the alarm has been acknowledged at the SCADA system. USFilter will mock -up the MTU ChippendalelWell #7), the CTU (Public Works), and the SCADA system at our facility to test the software changes before they are implemented in the field. Field work consists of loading an updated PLC program at the MTU, wiring of the output, and loading of an updated HMI program. The system will be tested with the interface to the City Wide Radio System. Items to Note: This proposal is based upon several e-mail exchanges, verbal discussions, and a site meeting. Please review the scope description and request clarification if needed. Provisions for items not specifically mentioned above are not included. The third -party interface card to the City's Radio System will need to be installed and functional prior to the implementation of USFilter's scope of work. Schedule Impacts: USFilter has been instructed by the City to cease startup of the sites to the new SCADA system until the Tone System is in place. We are requesting a four -week contract extension after the approval of the change order and the readiness of the Radio System to allow for the implementation of the change order and the completion of startup. Total sell price is $5,900.00 net; Terms: Quotation is valid for 20 days. Payment of work shall be in accordance with the established Schedule of Values for the project. Terms of USFilter contract with City of Rosemount apply. Thank you for this opportunity to be of service to you. I f you have any questions, please d on't hesitate to call.
