February 2019 City of Everett <br /> Exhibit A—Scope of Work <br /> Cost Estimate Summary <br /> Task Description Estimated Hours Reimbursed Estimated <br /> Principal CP Tech. Expenses Budget <br /> Perform an evaluation on four exposed sections of Transmission Line 5 near the water <br /> treatment plant. This assessment will determine if additional cathodic protection in this <br /> 1 area is warranted. Provide a report detailing the results of the inspection along with 20 Mileage$232 $4,143.00 <br /> recommendations. Excavation of Transmission Line 5 will be by others. <br /> Evaluate the compatibility of the existing PUD by-pass pipeline paralleling Transmission <br /> Line 5 with the proposed Transmission Line 5 cathodic protection system. Determine if <br /> 2 the potential for stray current exists on the PUD piping with the installation of a new 12 Mileage$58 $2,404.60 <br /> impressed current groundbed installed for Transmission Line 5. If the stray current <br /> interference is a concern,provide options for mitigation. Evaluate if both pipelines can <br /> be protected or otherwise benefit from the City's project. <br /> Initial cathodic protection system design for Transmission Line 5 has selected candidate <br /> sites for a new deep anode groundbed along with performing in-situ soil resistance <br /> testing. Task 3 will provide for completing the drawings and specifications. Services <br /> include selection of a final groundbed site,on-site inspection visits during installation, <br /> 3 commissioning support,development and review of final punch list,and provide an 50 Mileage$174 $9,951.50 <br /> installation and startup report to the City. All work associated with Task 3 is contingent <br /> upon the results of Task 1 which may result in not incorporating additional cathodic <br /> protection provisions for this section of Transmission Line 5. <br /> Measure electrical potentials at established test stations along the entire corridor and <br /> verify proper rectifier operation for Transmission Lines 2,3,and 4. This work will be <br /> 4 completed along the length of each line with City Staff present. It is anticipated that this 60 - Mileage$174 $11,907.00 <br /> task will be performed after City personnel have completed upcoming cathodic protection <br /> training. Provide a report of findings. <br /> Northwest Corrosion Engineering Page 2 of 4 <br />
