(considered preliminary) will be provided to the City or City's master plan consultant for review on a weekly basis within 3 days after interrogation (at the City's discretion, the data submittals may be reduced to a biweekly basis after the first 2 weeks if the initial data appears to be good). The final data will be compiled following removal of the flow meters and rain gauges. In the event that more than one flow meter fails to provide usable data during a significant storm event (> 0.5 inches of rainfall in 24 hours), V&A will extend the monitoring period for up to 2 weeks at no additional cost to the City. 3. Deliverables: V&A will submit a Flow Monitoring Report (3 copies) containing site details and pictures; field installation and maintenance sheets including calibration data; depth-velocity scatter plots; 7-day plots of flow for each meter and rainfall for each rain gauge; and summary tabulation of daily average, minimum, and peak flow for each flow meter. Electronic files will be submitted in Excel format containing depth, velocity, and flow rates for each meter and rainfall for each rain gauge in 15-minute intervals. Final report and data shall be delivered within 3 weeks of completion of flow monitoring. We propose to complete this work on a time and materials basis as follows: 12 Flow Meters and 1 Rain Gauge for 60 days: Weekly extension(s) to monitoring period (optional): $50,000 $5,000 per week Terms are Net 30 days and this price is valid for 90 days from the date of this proposal. The scope of work was developed as a result of our discussion and represents our mutual understanding. Estimated costs for the above project scope are itemized in the attached Resource Allocation Estimate. These costs represent our best estimates at this time and may change subject to future developments during the project. It is possible that some of the estimated manpower requirements for specific task items may increase while others may not require the entire anticipated effort. This provides us a greater degree of confidence in the overall project estimate, rather than in any given particular task. If unforeseen circumstances should arise which indicate that more time is required, we would provide a written estimate of additional required time and cost. We will not proceed with work beyond the not to exceed figure without a written authorization from your office. We are prepared to begin work on your project upon receiving written approval, a Notice to Proceed, or purchase order from your office. On behalf of our staff and myself I would like to thank you for the opportunity to be of service to you and the City of Redwood City. We look forward to working with you.
