WW11 - of Report Number 14 -060 BAIMMU14 Agenda Section VI -7 the city that works for you Council Meeting Date March 25, 2014 REQUEST FOR COUNCIL CONSIDERATION ITEM DESCRIPTION: CONSIDERATION OF QUOTE AND AUTHORIZATION OF CITY PROJECT 14 -6, WTP #1 IRON & CARBON FILTER PRESSURE TRANSMITTER REPLACEMENT. DEPARTMENT HEAD'S APPROVAL: (mow CITY MANAGER'S APPROVAL: No comments to subblement this Comments attached Recommendation: Accept the quote in the-fimount of $34,500.55 and authorize InControl to perform the necessary work required for City Project 14 -6, Iron and Carbon Filter Pressure Transmitters. Legislative History: This work is included in the 2014 annual work plan with the United States Army. Financial Impact: InControl, the controls integration contractor for the NBCGRS facilities, has provided a quote for replacement of the pressure transmitters on the iron and carbon filters in the amount of $34,500.55 based on an estimated maximum of 30 hours of labor. Freight for shipping of the transmitters is extra and will be added at the time of the work. Explanation: Each iron and carbon filter has a pressure sensor /transmitter that monitors the differential pressure in the vessel and sends a signal to the plant control system. Monitoring vessel pressure is critical for protecting the equipment against damage from unexpected high pressure and for indicating when the media is in need of backwashing. The pressure transmitters installed at the time of construction in the early and mid -1990s are now obsolete and are not supported by the manufacturer. Two of the transmitters have failed and cannot be repaired. Because these are critical components in the operation of the water treatment plant, it is prudent to replace all of the transmitters before more failures occur. The replacement of the transmitters is included in the 2014 work plan with a budget of $38,000 for completion of the work. InControl has provided services related to controls of the NBCGRS for more than 25 years. Using InControl for this work assures that the products installed are compatible with the overall control system and that programming for integration of the new equipment will be done correctly so that there is no interruption to pressure monitoring. Costs and Funding: The total cost of this project will be funded from Fund 206 — NBCGRS Army Water Fund. AJ- ko-- Grant W ffels, P. .
