For the 637E tractor scrapers and 777C off-road trucks, haul segment lengths and average grades <br />• were translated into haul and return times using the Caterpillaz VEHSIM, and FPC computer <br />haulage simulation softwaze. The following rolling resistance factors were used in the calculation <br />of cycle times: <br />• 3 percent for material movements on established azeas <br />• 4 percent for material movements in operating or dump azeas <br />Standazd fixed cycle times obtained from the Caterpillaz Performance Handbook were <br />utilized in determining total cycle times for each reclamation activity as summazized in Appendix <br />B, Productivity Documentation. A load factor was developed utilizing material density and swell <br />data and equipment volume and payload specifications from the Caterpillar Performance <br />Handbook. All calculations for haulage equipment productivity are included in Appendix B, <br />Productivity Documentation. <br />For wheel loader production, estimates aze based on cycle times, bucket capacity, payload, <br />and correction factors from in Caterpillar Tractor Performance Handbook. Production estimates <br />for loaders are 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 />Caterpillaz 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 are presented and summazized in Appendix <br />B, Productivity Documentation. <br />9.0 DETERMINATION OF EQUIPMENT EIOUR 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 chazacteristics 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, seven <br />777C haul trucks, three 992D loaders, eight 637E scrapers, three 14G motor graders, two 5,000 <br />e <br />
