Honorable Mayor and Members of the City Council: BACKGROUND A sanitary sewer flow diversion structure exists just outside of pump station S-8. The diversion structure provides the ability to redirect the flow of sewerage away from the pump station parallel piping, allowing for the emergency repairs to the pump station if needed. As part of the 2003-2004 capital improvement program, the S-8 diversion structure was identified as needing replacement. The structure was over 25 years old and had deteriorated, with portions of the vault's concrete wall spauling off and exposing the reinforcing steel within the structure. The sluice gates that control flows in and out of the structure had become corroded and deteriorated. The flow structure is approximately 8 feet wide, 17 feet long and 25 feet tall. Three sluice gates operate and direct sewer flows through the structure. Recently, one of the sluice gates failed. The gate stem had pulled away from the gate and left the gate inoperable. Fortunately, the gate was stuck in the open position and flows were being directed through the pump station (the nornial operating configuration). The other two gates were originally installed at the same time and were also considered to be in a similar poor condition. Therefore, there was an immediate need to go forward and replace the structure and appurtenant gates and hardware. On April 18, 2006, City Council awarded the project to the low bidder, Mitchell Engineering. The replacement sewer diversion structure is now complete and the project is ready for acceptance by City Council. The City has received a Stop Notice from American Asphalt R & R Company, Inc. stating that they have not received payment from Mitchell Engineering, Inc. for services rendered. Repaving of the existing pavement damaged during construction was performed by American Asphalt R & R Company, Inc., a subcontractor to Mitchell Engineering. The claim is in the amount of $10,500 and City staff will work with Mitchell Engineering to ensure that American Asphalt R & R Company, Inc. receives payment for work completed prior to . release of the final payment in the amount of $15,437.50. Therefore, it is recommended that final payment be made to Mitchell Engineering Inc. provided all claims have been settled upon the completion of the thirty date "Notice of Completion" to be fIled by the City Clerk. All project costs are listed below. Page 2 on
