• 3 percent for material movements on established areas <br />• 4 percent for material movements in operating or dump azeas <br />Standard fixed cycle times obtained from the Caterpillar Performance Handbook were <br />utilized in determining total cycle times for each reclamation activity as summarized in Appendix <br />B, Productivity Documentation, or the Caterpillar Fleet Production and Cost Analysis program <br />was used to determine equipment productivities. A load factor was developed utilizing material <br />density and swell data and equipment volume and payload specifications from the Caterpillar <br />Performance Handbook. Al] calculations for haulage equipment productivity are included in <br />Appendix B, Productivity Documentation. <br />For wheel loader production, estimates are based on cycle times, bucket capacity, payload, <br />and correction factors from in Caterpillar Tractor Performance Handbook. Production estimates <br />for loaders aze presented in Appendix B, Productivity Documentation. <br />In order to determine accurate productivity values for all reclamation functions, base <br />productivities calculated as described above were adjusted for altitude as indicated by the <br />Caterpillar Performance Handbook and adjustments were made for a working utilization of 50 <br />minutes per hour (0.83). This factor reflects the average to favorable conditions typical of a large- <br />scale reclamation project. The equipment productivity references utilized in the bonding cost <br />estimate calculations and all productivity calculations aze presented and summarized in Appendix <br />B, Productivity Documentation. <br />9.0 DETERMINATION OF EQUIPMENT HOUR AND FLEET REQUIREMENTS <br />Calculation of the equipment hours required to complete each reclamation function <br />involved dividing the material handling volumes as adjusted to reflect material characteristics by <br />the adjusted productivity rates. Because dozer requirements constitute the majority of the work <br />and time necessary to complete the overall reclamation project, total dozer hours were utilized as <br />the basis for determination of the project schedule. Atwo-shift per day, five-day per week <br />operating schedule was assumed for all reclamation functions, except facilities removal and <br />revegetation, which were scheduled on a single shift basis. Using this base working schedule and <br />the total required loader and truck hours, it was determined that seven D10N tracked dozers, <br />seven 777C haul trucks, three 992D loaders, eight 637E scrapers, three 14G motor graders, two <br />5,000 gallon water trucks and two overburden drills would be required to complete reclamation <br />work. <br />The proposed reclamation equipment fleet will optimize utilization of support and auxiliary <br />equipment and result in completion of reclamation in less than one year. Required hours for those <br />reclamation functions, which are sequenced to follow completion of loader/truck work, were <br />8 Revision Date: 5/8/03 <br />Revision No. TR-56 <br />
