<br />4 <br /> <br />APPROACH TO THE WORK <br /> <br />" <br /> <br />Our plan <br /> <br />is to conduct a continuous process o~ <br /> <br />coordination and analysis which will direct specific work <br /> <br />activities toward achieving an optimum dam configuration <br /> <br />while maximizing benefits. <br /> <br />The premise is that we will <br /> <br />assume no factors are favorable until an assumption is <br /> <br />that each <br /> <br />data. particularly field <br />assumption has been reviewed <br /> <br />supported by all <br />investigations. and <br /> <br />available <br /> <br />by the North Poudre Irrigation Company and determined to be <br /> <br />feasible from their point of view. <br /> <br />After each component of <br /> <br />study for a particular phase. a preliminary analysis will be <br /> <br />brie~ed into <br /> <br />a ~inal <br /> <br />report listing <br /> <br />~avorable <br /> <br />and <br /> <br />unfavorable circumstances with regard to the work. <br /> <br />The ~ield investigation program that we recommend is to <br /> <br />conduct borings in the dam area while installing piezometers <br /> <br />and conducting the appropriate laboratory tests to verify <br /> <br /> <br />the suitability of in situ soils materials. The borings in <br /> <br /> <br />the dam area will include soils sampling. and drilling and <br /> <br /> <br />sa.pling of the rock formations such that the geology of the <br />formations may be verified. Permeability tests will be <br /> <br />conducted to determine water loss through the formations by <br /> <br />conducting falling head permeability tests in the open <br /> <br />standpipe piezometers. <br /> <br />High water losses are not expected <br /> <br />in the overburden soils or the rock ~ormation. <br /> <br />Thus. water <br /> <br />pressure permeability <br /> <br />tests <br /> <br />(packer <br /> <br />tests) <br /> <br />are <br /> <br />not <br /> <br />anticipated to be required. <br /> <br />Laboratory permeability tests <br />
