Finish Grading . A cost has been estimated to finish grade the area with wheeled <br /> motor graders. This was based on CDMG estimated time frame of 81.1 hours. <br />Rill and Gully Repair. A cost to conduct the rill and gully repair (including <br />sediment ponds) has been included in this estimate. It has been assumed that <br />this task could be handled with a Cat D3C Dozer every two years and would <br />continue for the 10 year liability period. <br />Fleet Determination <br />Once the volumes for the various phases of reclamation were determined, the <br />number of shifts, hours per shift, equipment types, operator/operating <br />efficiencies, support equipment, and overall reclamation time span, all of which <br />ultimately affect mobilization and demobilization, had to be determined. The <br />following discussion provides the considerations utilized in determining the <br />equipment fleet needed. <br />Production Shifts. Keeping with current practice locally, one shift per day was <br />used for this estimate. Using one shift per day would allow for preventative <br />maintenance and minor equipment repair to occur on second shift, if needed. <br />Shifts were based on an eight-hour period per shift and a series of job <br />condition correction factors were built into the production estimate. <br />Equipment Types. The types of equipment selected were based on similar type <br />equipment presently operating in or around Routt County. Whenever possible, <br />Caterpillar equipment was used for reclamation due to widely published <br />information regarding costs and performance. All equipment costs were taken <br />from those provided by CDMG. Please see appropriate worksheets in Attachment <br />23-1 for a list of all cost factors. Equipment performance was based on <br />Caterpillar Handbook No. 29, or otherwise as noted. <br />Equipment and operator performance factors were based on generally published and <br />accepted criteria (see individual worksheets). <br />Operator wages were all based on information supplied by CDMG. <br />TR-07 5 Revised 03/06 <br />
