WPCF Headworks Replacement Project Scope of Work <br />35 <br /> <br />Task 401 Quality Assurance and Quality Control <br />Activities/Approach: Implement the QMP developed under Phase 200 for the alternatives analysis. <br />This work includes providing appropriate calculation and deliverable QA/QC reviews by in-house, <br />senior staff members. Work products are listed in subsequent tasks. Incorporate internal and City <br />review comments to prepare and complete listed work products. <br />This phase includes the following activities: <br /> Manage and execute the QMP for Phase 400 deliverables. <br /> Perform readability reviews for documents by technical editors. <br /> Perform discipline design reviews for all alternatives analyses and the draft Alternatives <br />Analysis Report. <br /> Perform reviews by facility leads for all discipline documents associated with each process <br />and/or facility. <br /> Conduct independent calculations review by experienced senior engineers. <br /> Verify that QA/QC reviewers concur with work products. Maintain written documentation of <br />QA/QC reviews and written responses. <br /> Set up and administer Bluebeam Studio cloud-based document reviews internally and <br />externally for concurrent review by City staff. The Studio session will be prefaced by project <br />training for City reviewers for commenting and adjudication procedures. <br />City Responsibilities <br /> Provide coordinated and consolidated collection of review comments and resolution of any <br />conflicting comments from the City reviewers prior to returning to the design team. <br /> Participate in the review process and provide an independent review of products. <br />Work Products <br /> QA/QC reviews documented with markup documents and/or comment logs for record- <br />keeping. <br /> Collection and storage of QA/QC documentation as required by the QMP. <br /> <br />Excel worksheet. <br />Deliverables <br /> None <br />Task 402 Design Criteria <br />Objective: The task involves analyzing historical and projected plant flow data to develop a process <br />flow diagram for the new headworks, including bypass procedures, and to establish the design flow <br />rate for the new facility. This work includes developing updated flow projections using historical plant <br />influent flow and the recently completed WPCF Facility Plan. This task will also define critical <br />hydraulic profile constraints for the new facility and establish additional process design criteria such <br />as screenings solids loading, grit production rates, and septage receiving station capacity. <br />Activities/Approach <br /> Examine historical plant flow data and existing flow projections. <br /> Review the 2022 WPCF Facility Plan to identify forecasted plant flow conditions.
