• Equipment and operator performance factors were based on generally published and accepted <br />criteria (see individual worksheets). <br />Operator wages were all based on information supplied by CDMC. <br />Reclamation Time Frame. A reasonable time frame for a job Of this magnitude is estimated <br />at approximately 900 hours for backfilling and grading, and 1,000 hours for topsoiling. <br />This is based on three D11Ns working two shifts per day and four 637s working one shi Et <br />per day. Some of the topsoiling can overlap the backfilling and grading; therefore, total <br />project time is estimated at six months. <br />Indirect Costs <br />The following is an estimate of indirect costs aesoci aced with the reclamation of the <br />Yoa st Mine. <br />Mobilization an3 Demobilization Costs <br />• Mobilization and demobilization costs were based oa mobilizing the major pieces of <br />equipment. The guidelines set forth in the OSM Reclamation Bond Handbook place a value of <br />mobilization and demobilization at one to five percent of the direct costs. SCC used the <br />five percent. <br />Engineering Redesign Fee <br />The reclamation plan as submitted is based on a planned life-of-mine operation. If mining <br />should cease before the planned date, some projects may need to be re-engineered or field <br />engineered. To account for these costs, Graph 1, OSMRE Hond Handbook was used the <br />estimate these fees. This was estimated at 4.9 percent of the direct costs. <br />ConCiactoi's Prof i[ and Overhead <br />Profit and overhead for the contractor was estimated using Graph 2, OHNRE Bond Handbook. <br />This was estimated at 7.3 percenc of the direct costs. <br />• <br />7 Revised 2101 <br />
