EXHIBIT A-3 7 SCOPE OF WORK Task 11. Easement Coordination The City will provide all easement acquisition services for the project. At the direction of the City, the Engineer will provide the following limited easement coordination assistance: A. Identify Easement Requirements. Identify the location and extent of any new temporary or permanent easements that are determined to be required for construction access or staging areas. Convey this information to the City and/or the City's Easement acquisition subconsultant. B. Limited Support and Assistance for Easement Acquisition. Provide limited technical support and coordination for the City and/or the City's Easement acquisition subconsultant for acquisition of up to two easements. The effort is limited to the budget established for this item. Survey documents for new easements are covered under Task 4. III. Final Design and Bidding Assistance Prepare the final design of the Phase 6 replacement of the existing Water Transmission Line 2 and 3 for the 48-inch diameter pipe based on the HDD concept. This work is further described by the tasks below. Task 12. Final Geotechnical Studies A. Field Explorations. The initial conclusion by the Engineer's project team is that the subsurface information contained in the ZZA Geotechnical Report for Phase 6 dated October 11, 2004 appears to be sufficient for design and construction of the HDD option within the City's existing transmission corridor easement. As a result, no additional field exploration within this portion of the alignment (for the HDD concept) is included in the scope of work. Two existing borings are located near the east transition section. Although these borings appear to provide adequate subsurface information for the buried pipe alternative, an additional boring may be required if the alignment of the buried pipe segment or the HDD entry/exit location for the east transition section is relocated outside of the existing transmission corridor easement. Any boring (and any other additional field exploration or laboratory testing), if needed would be considered additional services as described under Section V Additional Services. B. Engineering Analyses. Supplemental engineering analyses, evaluations and geotechnical recommendations will be completed by both ZZA and BSE based on the existing field exploration information for the proposed Phase 6 HDD project. Responsibilities for the various engineering tasks between the two subconsultants are identified below. Topics to be addressed include: 1.
