provide on-site observation and hydrogeologic services during drilling and testing of the wells ' open <br /> hole sections to an estimated depth of 700 feet. Data will be collected for identifying completion <br /> depths that will provide an optimal balance between maximizing well efficiency (reducing <br /> drawdown) and water quality. PBS&J' s hydrogeologic services, with assistance from the Contractor, <br /> will include sampling and describing the lithology of the drill cuttings, monitoring the specific <br /> conductivity of the discharge water, and conducting drill rod specific capacity test at every drill rod <br /> change. In addition, PBS&J will observe and evaluate the final geophysical logging event and 8-hour <br /> step drawdown test at each well, which will be specified to be performed by the Contractor <br /> Task 2 .5 — Well Completion Memorandums <br /> PBS&J will prepareseparateTechnical Memorandum (TM) which will detail the chronology of <br /> construction activities , document materials used, provide record drawings of each production well, <br /> describe the geology encountered, and provide results of the hydrogeologic testing. A draft copy of <br /> the each TM and record drawings will be provided for County review and comment. Four final copies <br /> of each TM will be provided to the County. <br /> Task 3 — Well Outfittine and Raw Water Line Design <br /> PBS&J will provide design services for outfitting each new off-site well with suitable pump, piping, <br /> valves, controls, and enclosures. PBS&J will prepare the contract documents in support of this <br /> construction effort as detailed in the following tasks. For budgeting purposes, it is assumed that the <br /> three new wells will be incorporated into one set of design contract documents for bidding (one <br /> construction contract) . <br /> For budgeting purposes, the following is a list of anticipated construction plans to be included in this <br /> final design effort: <br /> G- 1 Cover Sheet <br /> G-2 North WTF Well Field Piping Plan <br /> S - 1 Structural Notes and Abbreviations (largely the same as the design completed for the <br /> current three wells under construction) <br /> S -2 Typical Well Enclosure Structural Plans, Sections and Details (largely the same as the <br /> design completed for the current three wells under construction) <br /> S-3 Miscellaneous Structural Sections and Details (largely the same as the design completed <br /> for the current three wells under construction) <br /> M- 1 Typical Supply Well Pump and Piping, Sections and Details (largely the same as the <br /> design completed for the current three wells under construction) <br /> M-2 Miscellaneous Mechanical Sections and Details <br /> E- 1 North WTF Well Field Electrical Site Plan <br /> E-2 North WTF Well Field Wells 7 and 9 Electrical Site Plan <br /> E-3 Typical Well Enclosure Electrical Plan and Details <br /> E4 Miscellaneous Electrical Schedules and Details <br /> I- 1 Typical Supply Well Control Panel Wiring Diagram (largely the same as the design <br /> completed for the current three wells under construction) <br /> 1-2 Typical Supply Well Control Panel Wiring Diagram (largely the same as the design <br /> completed for the current three wells under construction) <br /> CAF1bw/X9.Fnvicnmenta]INDIAI;_RIVLR_COVRC_W WW2006\WO02_CUP-Wall;'.01_Propusuls\ I A_Proq/ als\l new wells s0\4\Attachnwnt 1 ] 12607 doc <br /> "t Revised 11!26.2007 1 28 PM <br /> 4 <br />
