Surveying, Mapping and Right-of-Way Support If required, CES can obtain digital orthophotographic map and a separate planimetric and topographic contour map (at one-foot intervals). Benchmarks for horizontal and vertical control can also be provided. The Team will support the City's right-of-way department in the following specific activities: ✓ Estimating construction corridor widths, including the preparation of typical sections showing trench widths, temporary stockpile locations, construction equipment dimensions and operating criteria, temporary traffic control measures, and clearances between the various construction zones necessary to afford safe working conditions. ✓ Identifying requirements for permanent access to the pipeline. 1 ✓ Using Assessor's Parcel Maps, documenting current land ownership along the alignment. ✓ Preparing Metes and Bounds descriptions of required property for both permanent and temporary easements. 1 Preliminary Geotechnical Investigation A preliminary geotechnical investigation, based on a desk-top literature review supported by field reconnaissance, will be conducted to assist in the establishment of preferred alignment corridors and facility sites. Geotechnical evaluations of soil and rock properties, groundwater, and potential geologic hazards at prospective sites will be summarized. Specific recommendations will be developed to facilitate engineering evaluations of alternative alignments and profiles including special considerations for pipeline trench stability, groundwater, tunneling and rock excavation. Conditions may differ substantially from those described above where pipelines cross developed areas. Local fill, imported material and disturbed formational materials probably are present due to earthwork performed for development. These conditions will be evaluated by a surface reconnaissance and subsurface exploration program during design. Thanks to our in-house materials testing lab, some limited geotechnical activities may be expedited to facilitate early decisions in the design analysis. a Value Engineering Review Throughout the design effort, the CES Team will seek the means to provide the most effective, cost-efficient, biddable and constructible design documents. We understand that this effort will 1 be augmented by value engineering (VE) reviews to provide essential functions in the most cost- effective manner, consistent with requisite performance, constructability, reliability, maintainability, and safety standards. The CES Project Manager and lead designers will provide required calculation and design documents to the VE Team Leader. We will make our technical experts available for the VE Team briefing. We recommend that the City also participate on the VE Team. The CES Team will make a design presentation to the VE Team, who will evaluate potential cost-saving options both for construction and total life-cycle costs. All VE Team's recommendations that maintain the design intent, reflect lower costs, and/or improve constructability and bidability will be implemented. Preliminary Design Cost Estimate A detailed breakdown in CSI format of our opinion of labor and material costs for construction will be prepared. From this stage through final cost estimate preparation, we will actively track cost changes to construction scope work items and maintain a "running" estimate for the City's periodic review in a project-specific web site.
