<br />rely on the 7 1/2 minute quadrangle maps published by the U.S. <br /> <br /> <br />Geological Survey for basin topographic information. Major structures <br /> <br /> <br />such as dams or siphons will use enlargements of portions of the quad <br /> <br /> <br />sheets as a basis for layouts. In some limited instances, field <br /> <br /> <br />measurements will be necessary to verify that proposed designs are <br /> <br /> <br />realistic. In particular, the route for the proposed East Paradox <br /> <br /> <br />Canal, because of the rough terrain traversed, will have aerial <br /> <br /> <br />photographs and strip topography prepared. <br /> <br />It is considered to be of primary importance that all reservoir sites, <br /> <br /> <br />diversion points and conveyance routes be inspected on the ground by <br /> <br /> <br />the principal project engineer and the geologist. Such observations <br /> <br /> <br />help to minimize the development of plans which in later stages would <br /> <br /> <br />be found to be totally unrealistic. <br /> <br />At this preliminary stage, structural layouts will follow conventional <br /> <br /> <br />practices as described in the various design manuals published by the <br /> <br /> <br />U.S. Bureau of Reclamation. At a later stage in project development <br /> <br /> <br />it may be desirable to introduce certain innovative new configurations <br /> <br /> <br />or construction methods. <br /> <br />Estimated quantities will be determined for major construction items <br /> <br /> <br />such as earthwork, concrete and pipe. Smaller cost items will be <br /> <br /> <br />estimated as a percentage of the major ones. A summary of unit prices <br /> <br /> <br />bid on recent siltilar types of work will be development, and from <br /> <br /> <br />these a unit price for cost estimating will be selected. <br /> <br />Some decisions will be required in order to eliminate certain <br /> <br /> <br />alternating features included in the study. In particular, the best <br /> <br /> <br />method for transporting water from Fall Creek to the Lilylands System <br /> <br /> <br />will be dependent on comparable costs and geologic conditions. The <br /> <br /> <br />size of reservoir to bel placed in Beaver Creek will be dependent on <br /> <br /> <br />cost compared to other options and operational advantages.
