Equipment Type. the types of equipment selected were pa sad on similar type equipment <br />presently operating at [he mine site or could prudently be brought in for a job of this <br />magnitude. Whenever possible, Caterpillar equipment w•as used for reclamation due to <br />widely published informs [ion regarding costs and performance. All equipment costs were <br />taken trom those provided 6y CDMG. Please see Tables 13.7-2 through 13-7.9 for a list of <br />aLl cost factors. Equipment performance was based on Cat Handbook No. 21, FPC, EM F, <br />Means, or otherwise as noted. <br />Equipment and operator performance factors were based on generally published and accepted <br />criteria (see individual worksheets). <br />Operator wages were ell based on the Davis-Bacon wage rates for government products as <br />published by the U.S. Department of Labor. AlL rates are based on Routt County, Colorado. <br />Reclamation Time Frame. A reasonable time frame for a job of this magnitude is estimated <br />at approximately 2000 hours for bee kfilling end grading, and 1000 hours for topsoiling. <br />This is based on three D11Ns working two shifts per day and four 637s working one shift <br />per day. Some of the topsoiling can overlap the bac kfilling and grading; therefore, total <br />project time rs estimated at eight months. <br />Mobilization and Demobilization Costs. Mobilization end demobilization costs were based <br />on mobilizing the equipment es listed on Yor ksheet MOB-1. <br />Engineering Redesign Fee (Contract Preparation) <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, PYCC used the chart provided by CDMG. This was <br />estimated at five percent of the direct costs. <br />Contractor Profit and Overhead <br />Profit and overhead for the contractor was estimated at ten percent of the direct cos [s. <br /> <br />13.56 Revised 12/07/93 <br />
