<br />[New] TASK 13 – PUMP STATION CONDITION ASSESSMENT
<br />The Consultant will review and analyze sixteen (16) pump stations (fourteen in Redwood Shores
<br />and two in Seaport). The pump stations include: No. 1, 2, 3, 4, 5, 6, 7, 10, 11, 12, 21, 24, 25,
<br />Centrum, Seaport #1, and Seaport #2. The Consultant will develop a process to identify and
<br />prioritize rehabilitation needs. The condition assessment will provide a list of issues at each pump
<br />station including recommendations on how to address the issue and the estimated cost for each
<br />issue. The assessment for Seaport Pump Stations 1 and 2 will be categorized under separate
<br />Subtasks from those located in Redwood Shores for funding purposes.
<br />Subtask 13.1 – Review Existing Document (for 14 Redwood Shores Pump Stations)
<br />The Consultant will review existing documentation for the pump stations including
<br />available plans, record drawings, equipment data, pump runtime data, maintenance
<br />records, and other relevant information both prior to site visits and as needed to prepare
<br />deliverables under Subtask 13.3. For each of the fourteen pump stations, the Consultant
<br />will prepare checklist forms for internal use in documenting major assets based on data
<br />provided by the City. These checklists will be used during the site visits to confirm the
<br />major assets (i.e.. equipment make/model, pipe sizes and material, valve locations and
<br />type, etc.)
<br />City staff will provide relevant data regarding pump stations and force mains, including
<br />record drawings, equipment data (such as cut sheets/shop drawings), pump curves,
<br />performance test data, motor data, pump runtime data, maintenance records, and
<br />previous reports.
<br />Subtask 13.1 Assumptions
<br />City will provide relevant data regarding pump stations and force mains. This is
<br />expected to include record drawings, equipment data including cut sheets/shop
<br />drawings, pump curves, performance test data, motor data, pump runtime data,
<br />maintenance records, and previous reports.
<br />Woodard & Curran will review existing documentation prior to site visits and as
<br />needed to prepare deliverables under Subtask 13.3.
<br />The checklists prepared prior to site visits will not be considered a detailed
<br />assessment form and will not be used to develop an asset management program.
<br />Subtask 13.2 – Conduct Site Visits and Operator Interviews
<br />The Consultant will conduct site visits and operator interviews, assuming four (4) pump
<br />stations per day or four (4) days of consecutive field visits (including the two Seaport pump
<br />stations). The existing conditions will be documented and photographed. Each asset will
<br />be confirmed against record drawings and other data, as listed under Subtask 13.1
<br />assumptions, provided by the City. The mechanical equipment and piping will be observed
<br />for noise, vibration, protective coating, corrosion, operating pressure, flows/leaks, broken
<br />or missing parts, or other signs of poor condition. Electrical equipment including
<br />Instrumentation and Control (I&C) hardware will be observed for corrosion, wire integrity
<br />(visual only), and apparent code compliance or deviations. Visual observations of
<br />electrical code (National Electric Code) violations regarding clearance requirements,
<br />missing arc flash hazard labels, and grounding methods will be documented. Structural
