Preliminary Design Stage <br />• Basis of Design Study: The Basis of Design summary report will consist of a <br />brief description of each improvement element, the associated design parameters and <br />equipment design criteria. Design features of the plant process, electrical, mechanical <br />(I VAC and Plumbing), architectural, structural, instrumentation and control, and civil <br />site components will be listed. The design summary will also include project <br />constraints /limitations, coordination items, needed approvals, detailed opinion of project <br />cost and a schedule of critical design milestones. <br />During preparation of the Basis of Design study, the DB team shall hold a minimum of <br />three design workshops with the City. These workshops shall be used to ascertain the <br />City's concerns, preferences, and project specific operation and maintenance issues. <br />These workshops will also be used to substantiate the information on which the project <br />will be designed and constructed. Specific discussions will include: equipment selection, <br />upgrades of existing facilities including OBC issues, operational considerations, <br />construction methods, design guidelines to be followed, cost impacts and schedule <br />impacts. The Basis of Design stage will be considered complete upon the City's <br />acceptance of the Basis of Design report. <br />• Preliminary Design: Preliminary design drawings will be produced after the <br />Basis of Design has been accepted by the Owner. Preliminary design deliverables will <br />include plan layout of the plant structures buildings and process equipment. Major <br />section drawings for plant improvements will be prepared during the preliminary design <br />as necessary. Other plant design drawings initiated during the preliminary design will be <br />process schematics, and a baseline instrumentation and control schematic. <br />The completion of the Preliminary Design work constitutes approximately 15% of <br />the overall design. <br />Design Development Stage <br />• Design Development Stage work will be produced after the Preliminary Design <br />has been accepted by the Owner. Design Development Stage deliverables shall be <br />submitted to the City Engineer and the Criteria Engineer (as the City directs) by the DB <br />through the FOR at the completion of the following: <br />30% completion of design stage; and, <br />■ 60% of completion of design stage <br />Design Development Stage deliverables at each stage shall take into account and address: <br />6 1Page <br />
