15.4 Assumptions <br /> 1. HDR will only provide recommended updates and revisions to existing standards and <br /> suggestions for new standards, if needed. <br /> 2. No new standards or specifications, or standard detail drawings, will be developed. <br /> 15.5 Deliverables <br /> 1. Chapter for CWP covering Design and Construction Standards and Specifications. <br /> Task 16 Capital Improvement Plan <br /> 16.1 Objective <br /> Prepare a Capital Improvement Plan that includes a description of each recommended project, <br /> together with a planning-level completion schedule, costs, prioritization, and justification. <br /> 16.2 HDR Services <br /> 1. Compile system improvements identified in other tasks necessary to remedy system <br /> deficiencies, meet regulatory requirements, and support system growth. <br /> 2. Compile system improvements to address replacement of cast iron pipes at high risk of failure <br /> and any pipes needed for redundancy of critical pipe. This will rely on information from risk <br /> analyses previously completed by the City, including categorization of cast-iron pipes into age <br /> classes demonstrated to be at higher risk of failure. <br /> 3. Review CIP from previous water system plan and determine projects that remain to be <br /> completed and their current applicability. Projects that still are relevant will be compiled with the <br /> other improvements identified. <br /> 4. Prepare a standard cost estimating methodology that will be used to compare and evaluate <br /> project alternatives. Costs will be updated to account for changes in schedule. Distribution <br /> system piping improvement costs will be based on King County Tabula data. <br /> 5. Work with the City during a workshop to discuss and develop project evaluation, screening, and <br /> prioritization criteria to be used in the selection of and prioritization of projects. The contents of <br /> the CIP table and project sheets will also be reviewed and refined at this workshop. <br /> 6. Prepare text describing the CIP prioritization process, project justification, and description. <br /> 7. As other project information is made available by the City, as appropriate, HDR will evaluate <br /> scheduling water capital improvement projects in coordination with other improvement projects <br /> in the same area. <br /> 8. Outline and summarize the schedule of capital improvement projects in a summary table by year <br /> for the first 10 years, projects between 10 and 20 years, and projects beyond the 20 year time <br /> frame. <br /> Everett Comprehensive Water Plan June 12, 2019 <br /> Exhibit A—Scope of Services Page 26 of 30 <br />
