<br />. <br /> <br />. <br /> <br />9 <br /> <br />our laboratory in Golden, Colorado, <br />tests will be performed on samples <br />potential borrow materials: <br /> <br />As a minimum, the following <br />of existing embankment and <br /> <br />Quantity Type <br />2 Water Soluble Sulfate Tests (for concrete design <br />considerations) <br />20 Moisture Content Determinations <br />G Moisture Content/Density Determinations <br />4 Hydrometer Grain Si~e Analysis <br />2 Atterberg Limits Determinations <br />2 Standard Proctor Co~paction Tests <br />2 Uulti-phase Consolidated-Underdrained Triaxial <br />Compression Tests (j points) <br />2 Consolidation Perme~bility Tests <br />2 Relative Density Te~ts <br />2 Pinhole Dispersion Tests <br /> <br />3.3 Geologic Evaluation <br /> <br />Prior to beginning the civil design portion of the study, a <br />thorough geologic evaluation of the dam and reservoir area will <br />be performed. The geologic evaluation will address the following <br />items: <br /> <br />o Local area and dam foundation geology <br />o Evaluation of reservoir ~rimeter for slide potential <br />o Faults and fault history that may affect the dam <br />o Seismicity and design acceleration of the region <br /> <br />The latter two items will be studied based on published U.S.G.S. <br />and State Geological Survey data. No extensive field mapping, <br />trenching or seismo-tectonic analyses are anticipated during <br />Phase T. <br />
