Professional Service Agreement <br /> The professional services provided by ADS will provide three months of sewer flow monitoring <br /> with an optional extension of 30 days. Ninety days is the minimum recommended time to provide <br /> sewer flow monitoring to develop dry weather diurnal patterns. The City will also receive the <br /> highest probability catching spring rainfall with a March installation. If the City does not receive <br /> enough measurable storms a 30 day extension or more may be necessary to complete the project. <br /> The flow monitoring will provide the measured flow required to calibrate and verify the computer <br /> model of the system within all nine areas targeted for inflow and infiltration reduction. Crawford <br /> Murphy and Tilly, Inc. will use the Lost Bridge North Basin and the Florian Basin data to calibrate <br /> and verify their computer model. The City will use the remaining target area basin data to prioritize <br /> future Inflow and Infiltration Reduction Projects. The cost for the 2017 Target Area Flow <br /> Monitoring Project is not to exceed$462,944.28 for a 90 day monitoring period, the price includes a <br /> 30 day extension of$89,828.28 if required. <br /> SCHEDULE: The services approved in this agreement will start in February and be completed by <br /> the end of August 2017. The City must follow an aggressive schedule to meet the ACO December <br /> 31, 2018 deadline. <br /> BUDGET AND STAFFING IMPLICATIONS: <br /> Budget Impact: The proposed Professional Services Agreement with ADS Environmental <br /> Services is for a cost not to exceed$462,944.28.
