estimated in the same manner. The resulting project duration is estimated at approximately 42 <br />weeks for earthmoving and 8 weeks for revegetation. Figure 1, Project Schedule, graphically <br />summarizes the sequencing and timeframes for major reclamation activities. <br />10.0 EQUIPMENT COSTS <br />Equipment costs utilized in the bonding cost estimate were obtained from the 2002 Cost <br />Reference Guide for Construction Equipment. <br />11.0 LABOR COSTS <br />Labor rates in the bonding cost estimate were obtained from the U.S. Department of Labor <br />and represent current Davis Bacon wage rates for Western Colorado. <br />12.0 FACILITIES DEMOLITION AND REMOVAL COSTS <br />Unit costs for removal of structures and facilities in the mine facilities and tipple azeas <br />were obtained from the standard reference, "Site Work and Landscape Cost Data", published by <br />the R. S. Means Company. For the mine facilities area, disposal of the resulting demolition debris <br />was assumed to occur in neazby pit backf"ill areas. For the tipple area, demolition debris would be <br />placed in the excavation resulting from demolition of the coal stockpile reclaim system. Facilities <br />to be removed are shown on the Facilities Regrading and Removal Map, Map 38. Details of <br />demolition costs by facilities type are shown in Appendix C, Cost Documentation. The method of <br />calculating costs is illustrated by the cost calculation worksheets presented in Appendix D, Cost <br />Tables. <br />13.0 REVEGETATION COSTS <br />Costs for revegetation and reseeding activities are based upon recent costs for work <br />completed at the Colowyo Mine and current ASCS rate schedules. Details of the revegetation <br />cost estimate aze presented in Appendix C, Cost Documentation. The method of calculating costs <br />is illustrated by the cost calculation worksheets presented in Appendix D, Cost Tables. <br />14.0 OTHER COSTS <br />Costs for complete downhole explosive service, including all loading and blasting <br />activities, were obtained from a quote by MSI. Details of the quote are provided in Appendix C <br />9 Revision Date: 10/23/03 <br />Revision No. TR-56 <br />
