<br />" <br />.' <br /> <br />\ \\ <br /> <br />. <br /> <br />. <br /> <br />~ " <br /> <br />2.0 SCOPE OF WORK <br /> <br />SRK proposes to perform the following tasks in accordance with our <br />Standard General Conditions of Contract. <br /> <br />2.1 Task 1 - Review of EXisting Information <br /> <br />This task will be performed simultaneously with Task 2 - Field <br />Investigation to ensure rapid collection of the data required for <br />remedial design. The purpose of the review is to familiarize SRK <br />with previous work performed at the site. This will prevent <br />unnecessary duplication during the investigation and data <br />collection effort and wi 11 thereby minimize the length and cost of <br />the investigation. <br /> <br />The review will concentrate on available information <br />concerning the configuration, condition and component material <br />properties of the outlet structure, the embankment and the dam <br />foundation. While significant gaps are believed to exist in the <br />available data base, especially concerning critical embankment and <br />foundat ion materi a 1 propert i es, we understand that some val uab 1 e <br />data from earlier investigations will be available. The results of <br />tracer dye flow tests in the new sinkholes is a good example of <br />existing data which is important and should be easily incorporated <br />into the proposed investigation. In addition, existing geologic <br />maps and air photos of the site wi 11 be obtained and evaluated. <br />l <br />Areal jOint patterns and fault traces will be delineated and <br />interpreted where possible and an evaluation of their significance <br />to sinkhole development will be made. <br /> <br />The proposed field investigation program will be refined based <br />on the review of existing information to maximize the effectiveness <br />and minimize the cost of the subsurface exploration. <br /> <br />-3- <br />
