t. <br /> EXHIBIT A - SCOPE OF WORK <br /> The following Scope Of Work details the corrosion control tasks to be completed for the <br /> City of Everett Pipeline 2 Replacement Phase 8A project. The work of this project <br /> includes the replacement of approximately 2,500 lineal feet of 48-inch diameter steel <br /> pipeline located between South Lake Stevens Road and SR 9. <br /> This Scope Of Work is based on the assumption that the existing impressed current <br /> cathodic protection systems Iocated along the pipeline route will provide the required <br /> protective current to the replacement pipeline. The work associated with the following <br /> Task Items will commence upon the City of Everett's Notice to Proceed. <br /> TASK 1: Initial Preparation and Field Data Collection <br /> 1. Review Geotechnical Investigation report submitted by Zipper Zeman Associates <br /> dated January 12, 2004. <br /> 2. Review available preliminary project drawings and specifications. <br /> 3. Investigate as to the presence of foreign pipelines crossings. <br /> 4. Collect in-situ soil resistivity data along pipeline route. <br /> 5. Collect soil samples to perform saturated soil resistivity testing. Submit soil <br /> samples to laboratory to test for levels of chlorides, sulfates, and pH. <br /> 6. Perform impressed current testing. to determine if existing cathodic protection <br /> systems will provide the required protective current to the new pipeline. <br /> 7. Verify proper operation of existing test stations (test lead continuity, reference <br /> electrode calibration, etc). <br /> 8. Test existing pipelines for possible AC influence from overhead power lines <br /> located in the pipeline ROW. <br /> TASK 2: Engineering Design <br /> 1. Provide Initial and Final Corrosion Control Engineering Design package. <br /> including specifications and drawings to the City of Everett. <br /> 2. Review final design package. <br /> 3. Provide contractor submittal review. <br /> TASK 3: Installation Support <br /> 1. Provide corrosion control equipment field installation inspection services. <br /> 2. Conduction cathodic protection equipment checkout and commissioning, <br /> including impressed current cathodic protection system adjustment as required. <br /> Submit letter report to City of Everett including commissioning data, conclusions. <br /> recommendations, and photographs of construction. <br /> A. 4 <br />
