EXHIBIT A <br />pw:WA\Everett\_Proposals\Everett 20th Street Sewer Rehabilitation Scope 2023-0314.doc Page 4 of 7 <br /> <br />o Review of possible bypass pumping staging areas, discharge locations, <br />and routing. <br />o Hydraulic analysis of proposed bypass system <br />o Develop a bypass pumping TM <br />Subtask 240 – 50% Design <br />• Prepare 50 percent design level plans, opinion of probable construction cost <br />(OPCC), project schedule, and specifications. <br />• Conduct Risk Management front end review of City supplied Division 0 <br />specifications. <br />• Conduct internal QA/QC review. <br />• Submit 50 percent plans, specifications, and OPCC. <br />• Conduct review meeting of 50% design with City Staff. <br />Task 200 Assumptions: <br />1. City to provide existing CCTV inspection of existing sewer main. <br />2. This task assumes that no entry will be required into any existing structure to <br />obtain the required information. <br />3. Utility locating will not be performed for this project. All information collected will <br />be readily available from the ground surface or maintenance access. This scope <br />of work assumes that all manholes can be readily accessed to collect measure <br />down information and no traffic control is being provided under this scope. Any <br />required traffic control for measure down collection of existing structure in <br />Broadway will be provided by the City, if City Staff is available at the time of the <br />investigation. <br />4. Base map will be prepared using City provided and certified-current GIS mapping <br />in AutoCAD format. <br />5. City will provide access to all manholes within the project limits not located within <br />existing City ROW. <br />6. No potholing work will be completed as part of this work. <br />7. The existing hydraulic model and flow data for the existing system, including <br />flows from the Navy, will be provided by the City. <br />8. No new flow meter data will be required for the bypass pump analysis. <br />9. Budget for 50 percent design level plans assumes that the 20th Street sewer will <br />be rehabilitated using City GIS base maps as the base for the design drawings. It <br />is further assumed that the sewer main rehabilitation can be completed within the <br />existing ROW. <br />10. Specifications will be completed in CSI format with City providing Division 0. <br />Task 200 Meetings <br />1. 50% Design comment review meeting. <br />Task 200 Deliverables <br />1. Survey base map using GIS.
