This work is part of the Water Treatment Plant Rehabilitation <br />Project (City Project No. 2016-006). <br />Background/Discussion: <br />During the warranty period and as both treatment plants were in operation, the media <br />retaining nozzles on the drain down system, which is part of the back wash system, were <br />clogging. Staff requested that AE2S and Shank look into the cause and find a solution to <br />mitigate the problem. <br />After meeting in March of 2022 a solution to correct this problem was discussed. AE2S sent <br />a Requested for Pricing (RFP) to Shank. After further review a modification was made to the <br />suggested repairs and an updated RFP was obtained from Shank on June 22, 2022. <br />Public Works received Change Order #26 at a cost of $59,830.00 for work to modify the drain <br />down piping at WTP #2 & #3 from Shank Constructors Inc. <br />Further Discussion: <br />AE2S has reviewed the change order proposal and recommends approving Charge order <br />#26. <br />Strategic Plan Strategy/Goal: Maintain and Plan for Infrastructure Improvements. Ensure <br />Clean Water and Maintenance. <br />Financial Impact: No financial Impact to the 2022 Budget. The 2022 Water Fund budgeted <br />estimate of $800,000.00 for Water Treatment Plant and Engineering Design. <br />Recommendation: <br />Staff recommends the City Council approve the attached resolution approving Change Order <br />#26 and the proposal from Shank Constructors for $59,830.00 for modifying the drain down <br />system at WTP #2 & #3. <br />Respectfully submitted, <br />Don Peterson, Director of Public Works/Parks and Recreation <br />Attachments; <br />Change Order #26 <br />
