15 <br />5) Lateral Earth and Static Pressures <br />vii. Potential for pile supported foundations <br />viii. Perform buoyancy calculations and propose methods to counteract buoyancy <br />forces if needed. <br />6. Evaluate constructabi lily issues including pipe support, dewatering, access, coordination <br />with WPCF operations, and anticipated construction schedule. <br />7. Develop construction constraints including wastewater flow bypassing requirements. <br />8. Preliminary Engineer's Estimate of Probable Construction Cost: <br />a) Estimate of the construction cost will follow the expected level of accuracy for an <br />Associate for the Advancement of Cost Engineering Class 5 estimate. <br />9. Provide in-house QA/QC of documents. <br />Client Responsibilities <br />1. Provide timely input on all deliverables and information requests from the Consultant. <br />Client reviews shall be -completed within 3 -weeks. <br />2. Provide consolidated review comments on provided (or City) forms. <br />3. _Actively participate in workshops to provide input and design recommendations and <br />preferences. <br />4. Provide desired input on features for new and upgraded facilities. <br />5. Provide input on existing and desired facility/plant operation. <br />6. Provide geotechnical information and reports for previous projects in the immediate <br />vicinity of the proposed Diversion Structure 0 project. <br />Assumptions <br />1. The Pre -Design report will be prepared as a DOE Engineering Report to demonstrate <br />continued regulatory CSO compliance of SRO3. Final model predicted flows for the <br />combined sewer rainfall time series along with the one year return flow from the Hayes <br />Street project will be provided by the City. Flow predictions from other future projects <br />such as the 17th Street interceptor will be based on the Comprehensive Sewer Plan <br />model or the most current City sewer model. <br />2. Geotechnical work will be completed, if needed, in the design phase and is not included <br />at this time. Structural assumptions will be updated at a later date when geotechnical <br />recommendations have been provided. <br />3. Location of existing utilities will be based on existing information; however, critical <br />utilities or those with anticipated conflicts will be verified in the surveying subtask prior to <br />final design. <br />4. Design flows and loads have been established through previous facility planning and will <br />be available for incorporation into the current design. <br />5. Existing plant PLC/SCADA network block diagram is available and will be provide in <br />AutoCAD format. <br />6. lire -Design Repo r i will be no more -'than 20 Mages and include approximately{ 6 11 "x1 r:' <br />figures (1 Pf__D's, 1 plan view layout, -i section vievr,(s), 3 clan/profile sheets). <br />",y LiVe'Sion S._.!.dLure 0 132 JCCpe ci SeiY;C_.. <br />
