Consultant will prepare final reports of Pipeline Evaluation and Associated Cathodic Protection Facilities, including Alternatives and Recommendations. The report will include all information contained within the various subtasks. Results of all testing, in graphical or tabular form as appropriate, will be included and will serve as a basis for future corrosion evaluation and maintenance on the pipeline. Consultant will obtain GPS coordinates of tested facilities to be included in the appendix to aid in future maintenance and testing needs. The reports will indicate the condition of the pipeline at the excavated locations. Results of testing and analysis may possibly be extrapolated to an area surrounding each excavation for several hundred feet up- and down -station. Recommendations will be made with respect to required repairs as well as a discussion of the possible merits of providing electrical continuity, dielectric isolation, and further cathodic protection if necessary. 2. Other Corrosion Tasks Upon request of the City Engineer or designee, Consultant will provide services for tasks related to the performance evaluation of insulating materials and other NACE standard activities, which may include the following tasks, as needed: • Testing soil resistivity and conductivity with pipelines • Evaluating the effectiveness of buried insulating joints • Evaluating the effectiveness of exposed insulating joints • Preparing engineering reports to document measurements, interpret results, and recommend improvements 3. Corrosion Engineering Design Services Based on the City's review of engineering and assessment evaluation reports, the Consultant will prepare a scope for potential construction projects to correct or mitigate any problems or deficiencies identified during assessment. Consultant will assist the City in preparing the scope of the recommended cathodic protection improvement projects including problem definition, feasible alternatives analysis, and selecting the most cost- effective project to address the problem. The required engineering design services performed by the Consultant may include the following tasks and other miscellaneous engineering services: • Attend meetings with City Staff to discuss cathodic protection topics • Conduct corrosion control design analysis and calculations • Prepare and draft construction plans and specifications for cathodic protection projects, including cost estimates at key design stages. • Review material submittals for cathodic protection systems for construction projects • Observe construction of cathodic construction plans and specifications.
