A preliminary layout will be prepared showing alternative methods for connecting the <br /> Marysville pipeline to the existing Chlorine Contact Channel. The City's comments on the <br /> preliminary layout will be addressed when preparing the final design. Design work, <br /> including the specifications, testing procedure,metering facilities, and connection details <br /> will be coordinated with the City of Marysville design team. Final drawings and <br /> specifications will be prepared and sent to the City of Everett staff and City of Marysville <br /> staff for review. Comments from both City staffs will be addressed when preparing final <br /> design. Design work will include a new isolation valve located between the Chlorine <br /> Contact Channel and the trickling filters. The proposal form will be modified to show the <br /> Marysville portion of the work as a separate bid item. Questions from bidders will be <br /> addressed and responses will be included in an addendum as necessary. <br /> Subtask 5.9. Permitting, Design Review, and Bidding Services for Pipeline <br /> Crossing under Railroad Tracks near Kimberly-Clark Mill <br /> This subtask includes permitting,design review,and bidding services associated with <br /> design of a pipeline crossing under the railroad tracks and under West Marine View Drive <br /> near the Kimberly-Clark mill. The design drawings and specifications for this work will be <br /> included as an addendum to the bid documents. Work includes completing the railroad <br /> permit application,a site visit to the Kimberly-Clark mill to observe the potential <br /> construction conflicts,determining any Kimberly-Clark site requirements,reviewing <br /> drawings,modifying specifications,preparing an opinion of probable cost,revising the bid <br /> proposal to account for the longer length of pipe,conducting a site tour for potential <br /> bidders,coordinating design work with Kimberly-Clark staff,modifying the insurance and <br /> safety requirements in the bid documents,responding to bid questions,modifying the <br /> Geotechnical Data Report to include the boring within the Kimberly-Clark mill site,and <br /> preparing a Geotechnical Baseline Report. <br /> Subtask 5.10. Additional Geotechnical Investigation <br /> The existing subsurface information in the vicinity of the Chlorine Contact Channel(CCC) <br /> indicates that a layer of soft silts may be located just below the existing pile tips. There is a <br /> concern that the added weight of the proposed South Effluent Pump Station may cause <br /> excessive settlement of the CCC structure. This subtask includes installation of a deep test <br /> boring adjacent to the CCC to determine the extent of the soft silt layer,laboratory <br /> consolidation testing of soil samples to determine the coefficient of consolidation,analysis of <br /> the test results,and preparation of a technical memorandum. <br /> Subtask 5.11. Provide Engineering Services for Design of BNSF RR Crossing <br /> This task was originally Task 12 of the scope of services for Kimberly-Clark. The task <br /> includes engineering support as requested to design and prepare drawings and <br /> specifications for the BNSF railroad crossing for the City of Everett outfall line in the vicinity <br /> of the Detreve warehouse. This design will include the new City of Everett pipeline from <br /> the connection with the dished head fitting on the City pipeline on the west side of West <br /> Marine View Drive to the top of the vertical section in the jacking pit where the City line <br /> EXHIBIT A-JULY 16.DOC <br /> 2 <br /> 66 <br />
