WPCF Headworks Replacement Project Scope of Work <br />43 <br /> <br />Task Assumptions <br /> The report will include the alternative topics evaluated under Task 405. A description of <br />which topics will be covered within the main body of the Alternatives Analysis Report is noted <br />within the topic descriptions provided in Task 405. <br />City Responsibilities <br /> Review and comment on the draft report. <br />Meetings <br /> None <br />Work Products <br /> None <br />Deliverables <br /> Draft and Final Alternatives Analysis Reports <br />Phase 450 Basis of Design <br />Under this phase, BC will establish the basis of design concept for the new WPCF headworks facility <br />and process. This work will build upon the alternatives analysis completed under Phase 400 by <br />establishing clear project definition around equipment process sizing, facility locations, and general <br />arrangements. The engineering team will refine and add project definition to design criteria for the <br />headworks facilities, including process equipment sizing, development of the hydraulic profile, and <br />continued vendor outreach and coordination started during the alternatives analysis phase. With the <br />conceptual design established, the BODR will be drafted, documenting this work for submittal to <br />Ecology to meet the requirements for an Engineering Report per Washington Administrative Code <br />(WAC) 173-240-060. The BODR will define the project design criteria for each discipline and outline <br />the criteria that will be used during the detailed design phase of the project. <br />Task 451 QAQC <br />Objective: Implement the QMP for review of project calculations and work products. Based on the <br />QMP, provide appropriate calculation and deliverable QA/QC reviews by senior staff members in- <br />house. Work products are listed in subsequent tasks. <br />Activities/Approach <br /> Manage and execute the QMP. <br /> Perform QA/QC of the BODR. <br /> Conduct independent calculations and deliverable review by experienced senior engineers. <br />Responses to internal reviews and City comments will be tracked and maintained in the <br />project file. <br /> Have technical editors perform readability reviews of documents. <br /> Document QA/QC activities, including signoff from reviewers, review comments, and <br />responses. <br />Task Assumptions <br /> Internal QA/QC review will be completed under this phase. Comments will be addressed by <br />the technical team under Tasks 455 through 459. <br /> Regulatory coordination will be completed under Phase 100 Task 130.
