<br />. <br /> <br />. <br /> <br />Task 3 - Obtain Site Access - The Contractor shall make all reasonable <br />attempts to secure the necessary access to the sites for the geologic <br />mapping, the site drilling, and the construction materials drilling and <br />sampling. <br /> <br />The Contractor shall prepare an "access plan" which documents the pertinent <br />ownerShips for each site and the plan for obtaining access. This plan shall <br />be upgraded to include record of contacts made by the Contractor in <br />attempting to obtain access. Should access at any site be blocked, the <br />State will promptly be informed, along with an appraisal of the effect on <br />the entire study. <br /> <br />Task 4 - Geologic Mapping - Two types of geologic mapping shall be conducted <br />by the Contractor. The first component will be on a broader areal basis to <br />provide information relating to selection of specific dam sites. This areal <br />mapping will cover the reservoir areas and potential dam sites. The primary <br />objective is to define the structural geologic features and lithology of the <br />area. Rock units already designated as formations by the USGS will be <br />mapped. The mapping will note structural features such as the strike and <br />dip of the beds, joint patterns, slumping, and faulting. These features <br />will be mapped on the surface in sufficient detail to enable projection of <br />surficial features to the subsurface. This general areal mapping will be <br />initiated after aerial photographs and topographic maps are available for <br />reference. The completed geologic mapping will be the primary information <br />source to be used in selecting the dam locations, for locating prospective <br />construction materials, and for evaluating reservoir stability. At the <br />conclusion of this phase of the geologic mapping task, a meeting will be <br />held with CWCS personnel, to identify the dam sites that will be mapped in <br />the next phase. <br /> <br />The second type of geologic mapping shall be carried out on the specific <br />foundation and abutment areas of each dam axis. This detailed geologic <br />mapping activity will identify the geologic units and structure in more <br />detail than the areal mapping and will describe the nature of the soil and <br />rock exposed. Special attention will be given to identification of faults <br /> <br />A-4 <br />
