REV: 04-04-25 LR <br />Subtask 13.3 – Prepare Draft Pump Stations Condition Assessment Technical <br />Memorandum (TM) <br />The Consultant will compile the work conducted under this task into a Technical <br />Memorandum (TM) for use by the City. The efforts included in the development of the TM <br />include, but are not limited to the following: <br />Document existing conditions. This will take the form of representative photos and <br />brief descriptions. <br />Identify issues that require immediate attention (typically conditions where failure <br />may be imminent, or which represent an apparent risk to health and safety or <br />operators or the public). Issues will be given a numerical ranking based on the <br />criticality of the issue. <br />Estimate the remaining life of key pump station assets per site. This includes <br />pumps, valves, piping, blowers, odor control systems, electrical, etc. based on <br />year installed and/or existing condition. Support systems (e.g. seal water, gas <br />monitoring/life safety systems, or similar) will be assessed as systems rather than <br />individual components. <br />The TM will include a conceptual level remaining life assessment for assets. <br />Engineer’s Estimate of Probable Cost (planning level estimate, AACE International <br />Level 5) will be developed for issues, systems, or equipment with 10 years or less <br />years of remaining life. Detailed cost breakdown will not be prepared. <br />Deliver the Draft TM for City review. <br />One meeting to review and discuss City comments on the Draft TM. <br />Subtask 13.3 Deliverables: <br />Draft Pump Station Condition Assessment and Rehabilitation / Replacement TM <br />(Electronic files) <br />Meeting agenda and minutes <br />Subtask 13.3 Assumptions <br />No assessment of process/electrical capacity or expansion evaluation to meet increased <br />flow or more stringent permit requirements is included in the scope of work for this task. <br />The assessment results from all sixteen (16) pump stations (Redwood Shores and <br />Seaport/Pacific Shores) will be included in one TM, but the effort to complete the TM will <br />be separated by Subtask. <br />Equipment/system remaining life will be based on typical useful life for equipment in the <br />installed conditions and the assumed age of equipment/systems. Age of <br />equipment/systems will be calculated by one of the following methods depending on <br />available data: <br />o Assume that equipment dates to the most recent record drawings that included the <br />equipment. <br />o Specific installation year or timeframe if known by City staff. <br />ATTY/AGR.2025/Amend.
