<br />" . <br /> <br />SCOPE OF WORK <br /> <br />Task Description <br /> <br />1. Document Review and Equipment Preparation - Review available drawings and reports prior to <br />the field evaluation to determine the personnel and equipment requirements for the condition <br />assessment. Prepare safety equipment and personnel protective equipment necessary for the <br />manned entry and evaluation of the header. <br /> <br />2. Safety Plan - Submit a safety plan to the City prior to the confined space entry. The safety plan <br />will document the entry approach, identify possible hazards, include methods for safely crossing <br />each 3D-inch pump discharge pipe and provide rescue procedures for the internal evaluation of <br />the header piping. <br /> <br />3. Condition Assessment - Conduct a confined space entry through the 42 inch diameter blind <br />flange to evaluate the interior condition of the piping for a distance of approximately 75 feet. The <br />condition of the internal pipe surfaces and exposed portions of the welded steel pipe will be <br />documented using the following methods: <br /> <br />a. Digital photographs or digital video of defective areas of the pipe lining or exposed pipe <br />surfaces. Concrete condition assessment by sounding and penetration measurements with a <br />chipping hammer. <br /> <br />b. Damaged areas on the interior will be recorded and communicated to the technician on the <br />outside of the pipe. The thickness of the pipe will be measured and recorded to document <br />the extent of metal loss due to internal corrosion. UT will be measured from the pipe exterior <br />on exposed areas of the pipe. UT will be measured from the interior of the pipe at buried <br />areas of the pipe. <br /> <br />c. Measure pipe-to-soil potentials, anode current outputs and insulating effectiveness to <br />evaluate the condition of the CP system. <br /> <br />4. Technical Report - Prepare a report that documents the results of the condition assessment. The <br />report will include areas of corrosion damage, UT measurements, percent metal loss and results <br />of the CP system evaluation. The report will provide recommendations for internal and external <br />corrosion control. Rehabilitation methods will be recommended for areas with severe corrosion <br />damage. <br /> <br />V&A proposes to complete this work on a time and materials basis at a total cost not to exceed $9,900 <br />with terms of net 30 days. This fee is valid for 90 days from the date of this proposal. The scope of work <br />was developed as a result of our discussions and represents our mutual understanding. <br /> <br />Estimated costs for the above project scope are itemized in the attached Resource Allocation Estimate. <br />These costs represent our best estimate at this time and may change subject to future developments <br />during the project. It is possible that some of the estimated manpower requirements for specific task items <br />may increase while others may not require the entire anticipated effort. This provides us a greater degree <br />of confidence in the overall project estimate, rather than in any given particular task. <br /> <br />If unforeseen circumstances should arise which indicate that more time is required, V&A will provide a <br />written estimate of additional required time and cost. V&A will not proceed with work beyond the not to <br />exceed figure without a written authorization from your office. Charges to this project will be made for <br />actual time spent on the project and will be charged as per the attached Fee Schedule. We request that <br />you carefully review this proposal to assure full understanding of the scope of the work. Our Fee <br />Schedule is adjusted annually in January. Fees will be adjusted at that time and a new Fee Schedule will <br />be sent. Charges on the remainder of the project will be based on the new schedule. <br /> <br />Page 2 of 4 <br />
