City of Pleasanton (0012108.00) 4 Woodard & Curran, Inc. Woodard and Curran Condition Assessment Scope_14Feb24 February 9, 2024 Task 8 – Pump Station and Force Main Condition Assessment This task involves the review and analysis of twelve (12) pump stations and developing a process to identify and prioritize rehabilitation needs. It also includes the evaluation of the associated force mains for condition assessment. Subtask 8.1 Review Existing Documentation W&C will review existing documentation for the pump stations and force mains including as-built plans,equipment data, and maintenance records. Subtask 8.1 Assumptions • City will provide relevant data regarding pump stations and force mains. This is expected to include as-built plans, equipment data including cut sheets/show drawings, pump curves, performance test data, motor data,. Subtask 8.2 Prepare Pump Station Assessment Forms and Force Main Assessment Plan For each of the twelve pump stations, W&C will prepare assessment forms documenting major assets and condition including pumps, valves, mechanical equipment, electrical gear, and support systems based on data provided by the City. The initial (draft) format of these forms will be shared with the City for review and comments, as will the initial list of assets or systems intended to be assessed during the site visit.. Once the format is finalized, Woodard & Curran will fill in available data for assets/systems in preparation for the site visits (Subtask 8.3). For each pump station force main, Woodard & Curran will review record drawings and operations data to develop a list of recommended locations for field testing. These will likely include high points or other high-risk areas where pipelines may be especially subject to corrosion, or areas where breaks have occurred in the past. This list will be summarized in a “Force Main Assessment Plan”, including large scale maps or other means of field locating the recommended locations for excavation and in-situ testing (by others). Subtask 8.2 Assumptions • City plans to hire crews to excavate force mains at select locations, per W&C recommendations. The excavation work is per separate contract, as is the work to assess force main condition, which is anticipated to include non-destructive pipe wall testing and visual observation. Woodard & Curran will not participate in field testing of force mains. • Major assets like pumps, motors and drives will be assessed as indivdual assets. Piping and smaller support system components (e.g. seal water) will be assessed systematically to limit the level of effort required to document the condition of these systems. Subtask 8.2 Deliverables • Pump station asset/system list (each pump station) • Draft field assessment forms EXHIBIT B.1DocuSign Envelope ID: 5A406C2C-41AC-4CD1-B24B-4EEEED3DC26E
