V&A shall report to the City within 24 hours of each site visit if any meter has <br /> malfunctioned or failed to provide good data, or if changes in site conditions have impacted collection <br /> of good data. Field calibration data (independent measurements of flow depth and velocity) will be <br /> collected throughout the monitoring period for each meter to verify monitor accuracy over a range of <br /> flow depths. The monitor data will be collected at 5- minute intervals and reported at 15- minute <br /> intervals. The meters will be interrogated at each site visit and the data (considered preliminary) will <br /> be provided to the City for review on a weekly basis within 3 days after interrogation (at the City's <br /> discretion, the data submittals may be reduced to a biweekly basis after the first 2 weeks if the initial <br /> data appears to be good). The final data will be compiled following removal of the flow meters and <br /> rain gauges. In the event that more than one flow meter fails to provide usable data during a <br /> significant storm event (> 0.5 inches of rainfall in 24 hours), V&A will extend the monitoring period for <br /> up to 2 weeks at no additional cost to the City. <br /> 3. Deliverables: V&A will submit a Flow Monitoring Report (3 copies) containing site details and pictures; <br /> field installation and maintenance sheets including calibration data; depth - velocity scatter plots; 7 -day <br /> plots of flow for each meter and rainfall for each rain gauge; and summary tabulation of daily average, <br /> minimum, and peak flow for each flow meter. Electronic files will be submitted in Excel format containing <br /> depth, velocity, and flow rates for each meter and rainfall for each rain gauge in 15- minute intervals. <br /> Final report and data shall be delivered within 3 weeks of completion of flow monitoring. <br /> We propose to complete this work on a time and materials basis as follows: <br /> 7 Flow Meters and 1 Rain Gauge for 60 days: $35,000 <br /> Weekly Extensions of Flow Meters and Rain Gauge: $3,800 per week <br /> Terms are Net 30 days and this price is valid for 90 days from the date of this proposal. The scope of work <br /> was developed as a result of our discussion and represents our mutual understanding. Estimated costs for <br /> the above project scope are itemized in the attached Resource Allocation Estimate. These costs represent <br /> our best estimates at this time and may change subject to future developments during the project. It is <br /> possible that some of the estimated manpower requirements for specific task items may increase while <br /> others may not require the entire anticipated effort. This provides us a greater degree of confidence in the <br /> overall project estimate, rather than in any given particular task. <br /> If unforeseen circumstances should arise which indicate that more time is required, we would provide a <br /> written estimate of additional required time and cost. We will not proceed with work beyond the not to <br /> 10 - 0614 Storm Page 5 of 8 <br />
