Resolution No. 4083 designated Automatic Systems <br /> as a sole source supplier. Staff has received the final proposal <br /> from Automatic Systems , they have listed 2 options for the <br /> control system. The first option is to supply a "semi-hot" back- <br /> up computer in the new treatment plant to monitor the system and <br /> be available to replace the control computer at the shops in the <br /> event of a failure. The cost is $19,610. <br /> The second option does not include a back-up computer. Instead <br /> the back-up function would be supplied by the back-up panel <br /> currently in the shops. This option does not provide for the <br /> back-up of record keeping functions such as amount of water <br /> pumped, chlorine residual levels. or similar information. The cost <br /> for this option is $3,785. <br /> Because of the record keeping information, especially chlorine <br /> residual levels, staff recommends the first option. In either <br /> case the City needs to also install additional wiring between the <br /> shops and the new water plant. This is estimated to cost <br /> approximately $3 , 000 . A small contingency should also be <br /> authorized for unforeseen costs. <br /> Ric Mine'or <br /> City Engineer/Director of Public Works <br /> RECOMMENDATION; Staff recommends authorizing staff to purchase <br /> the new water treatment plant control system from Automatic <br /> Systems Co. for $19,610 with a $2 ,000 contingency, and a $3,000 <br /> allowance for wiring, to be charged to account # 680-4121-703 . <br />
