Project Coordination and Invoicing <br />Engineer will provide project supervision, direction, and coordination with the Owner’s <br />management and staff. Project administration and management also includes budget and <br />schedule control, client management support, document control, coordination of activities, <br />monthly invoicing, and project close-out for up to 27 months. Engineer will maintain a <br />change register of any scope changes affecting the project budget or schedule and review it <br />with the Owner monthly. Engineer shall discuss and receive written approval for any scope <br />changes from the Owner prior to proceeding. <br />PHASE 1 – PRELIMINARY DESIGN, DESIGN, AND BID PHASE SERVICES <br />Task 102 – Process Evaluation <br />The existing WAS Thickening process will be evaluated, and recommendations will be provided <br />for treatment process improvements. Currently, waste activated sludge is pumped continuously to <br />the DAF units in the DAF Building. The DAF units are at the end of their useful life and in need <br />of replacement. <br />Waste activated sludge flow (current average, current peak of 77 mgd, future average, future peak <br />of 100 mgd) along with loading information will be analyzed and used to evaluate the following <br />technologies: DAF (in-kind), gravity belt thickener (GBT), thickening centrifuge, and rotary drum <br />thickener (RDT). The existing mixers, grinders, thickened sludge pumps, and waste activated <br />sludge pumps will be inspected and recommendations for improvement will be provided. Engineer <br />has assumed that the thickened sludge pumps will be replaced, and the waste activated sludge <br />pumps will be reused. The dry polymer feed system supporting the WAS Thickening process was <br />replaced in 2008 and is nearing the end of its useful life. The system will be evaluated for <br />suitability with the WAS Thickening process equipment options and a recommendation for <br />improvements to or replacement of the polymer feed system will be provided. If selected by the <br />Owner, design of a new polymer feed system can be provided as a supplemental service. The <br />existing HVAC system and code requirements will be reviewed to ensure compatibility with the <br />selected WAS Thickening equipment and if updates to the HVAC system are required, design of <br />these improvements can be provided as a supplemental service. <br />The results of the process evaluation will be summarized and presented to the Owner in a WAS <br />Thickening PowerPoint presentation. The Owner’s comments will be incorporated in the meeting <br />summary documenting the meeting and decisions moving forward. <br />Task 103 – Basis of Design Memorandum <br />A Basis of Design Memorandum (BDM) will be prepared to provide design information and <br />project direction related to both bid packages. The BDM will establish design criteria, project <br />design schedule, project sequencing plan, control descriptions, and other important project design <br />information. An electronic copy in PDF format of the Draft BDM will be provided to the Owner <br />for review to finalize design criteria prior to moving forward with design. The Owner’s comments
