• Eguipment Type. The types of equipment selected were based resentl eratin at the mine site or could rudentl be o on similar type brou ht in for equipment a job of p y g p y p g this magnitude. whenever possible, Caterpillar equipment was used for reclamat ion due to widely published information regarding costs and performance. All equipment costs were taken from those provided by CDMG.. Please see Tables 13-1-2 through 13-1-9 far a list Of all Cost factors. Equipment pelfonmsnce was based on Cat Handbook No. 21, FPC, EMF, Means, or otherwise as noted. Equipment and operator performance factors were based on generally published and accepted criteria Isee individual worksheets). Operator wages were all based on the Davis-Bacon wage rates for government products as published by the U.S. Department of Labor. All rates are based on Routt County, Colorado. Reclamation Time Frame. A reasonable time frame for a job of Chis magnitude is estimated at approximately 2000 hours for backfilling, grading, and 1000 hours for • topsoiling. This is based on three D11NS working Cwo shifts per day and four o37s working one shift per day. Some of the topsoiling can overlap the backfilling rid grading; therefore, total project time is estimated at eight months. Mobilization and Demobilization Costs. Mobilization and demobilization costs were based on mobilizing the equipment as listed on Worksheet MOB-1. Engineering Redesign Fee The reclamation plan as submitted is based on a planned life-of-mine operation. If mining should cease before the planned date, some projects may need to be re-engineered or field engineered. To account for these costs, PWCC used the chart provided by CDMG. This was estimated at five percent of the direct costs. Contractor Profit and Overhead Profit and overhead for the contractor was estimated at ten percent of the direct cost 1I `` u 13-56 Revised 12/01/93
