REQUEST FOR PROPOSAL <br />On -Call Water Resources Engineering Services <br />(RFP NO.19.100) - ,W <br />used to calibrate the model to within 10% of actual readings, which is an industry standard <br />acceptable calibration level. <br />• Analyze System: Michael Baker will use the calibrated model to analyze the system under different <br />operational conditions, aka, different model scenarios. These scenarios will analyze the system <br />operation under existing and future demand conditions. <br />• Provide Draft and Final Reports: All findings and processes as mentioned above will be <br />described in detail in a report. Draft report will be submitted for review and after addressing City <br />comments, final signed report will be submitted to the City. <br />Condition Assessment <br />• Review Existing Facility Information and As-Builts: This task includes collecting available data <br />and performing a table top review of the facility based on the record drawings and other available <br />information. Michael Baker will research and collect available data through the City and other <br />sources for this task. The review will also include the facilities' Operational and Maintenance <br />Manual (O&M Manual). <br />• Review Maintenance Records and Testing Documents: We will also request, collect, and review <br />any maintenance or testing documents that are available for the facilities. This will help us to <br />understand if the facilities have undergone their regular maintenance and if any major upgrades <br />have been made. <br />• Perform Site Visits: Michael Baker's engineering team (and subconsultants, if needed) will attend <br />site visits to review and document existing conditions at the facilities being reviewed. Visual <br />inspection and photographic documentation will occur during this task. <br />• Perform Field Testing (if necessary): If needed (depending on the facility type), field testing will <br />be suggested and can be performed by either Michael Baker and our subconsultants, or by the City <br />crew. The non-destructive tests will be designed to collect additional information about the facility, <br />their performance, and their remaining life. Tests will include, but are not limited to: smart ball <br />technology for leak testing, SAHARA technology, CCTV inspection of water lines, flow testing at <br />hydrants or pumping facilities, etc. <br />• Analyze and Provide Recommendations: Michael Baker will review data already collected <br />through research, site visit and visual inspection, and testing, and will create a Risk Factor Table <br />based on the "Severity" and "Importance" of each item. Risk factor table will be used to prioritize <br />maintenance/upgrade requirements. Preliminary cost estimates will be developed for each <br />remedial option, and recommendations will be discussed with the City. <br />• Provide Draft and Final Reports: A summary of processes and steps taken, along with a detailed <br />description of the analyses, results, and recommendations will be presented in a draft report for the <br />City review. Once comments and concerns are addressed, final report will be submitted to the City. <br />Design - Pump Station Improvements <br />• Pumps and Associated Piping: We will develop system head curves based on the available <br />information as well as utilizing the City's hydraulic model that would be available to us. Based on <br />the available data, we will calculate the proposed Total Dynamic Head (TDH) and required flows <br />(GPM) for each pump. We will use Hydraulic Institute Standards (HIS) guidelines and <br />recommendations in pump station design, to assure our design meets and exceeds industry <br />standards. Total number of pumps for each pump station will be determined based on the minimum <br />and maximum demands. If one pump cannot cover the wide range of demands, two duty pumps <br />will be designed. One standby pump will be provided for each pump station as back up. <br />• Pump and System Curves: The customer service elevations vary for each pump station. Each <br />pump station must develop sufficient discharge pressure to provide a minimum hydraulic grade <br />elevation to overcome different elevations in their service zone and provide sufficient pressure at <br />Proposal I Page 13 On -Call Water Resources RFP No. 19-100 <br />I N T E R N AT T 0 N AL <br />
