This HW evaluates your ability to properly use the CAT dozer productivity estimation. Refer to the CAT handbook pg. 19-50 to 19-55. And, given facts shown below, answer the questions: Facts: - Assume that the contractor selects a CAT D9T tractor with an "SU" blade. - The average dozing distance for the job will be 350 feet and the gradient will be about 20% downhill. - The material will be "hard to drift or cut". - A slot dozing technique will be used by an "average" operator. - The material has a loose density of 2,000 lbs (i.e., material weight of 2000lbs per LCY) - There will be no visibility issue. - The job efficiency is assumed to be 50 minutes per hour. Question 1) Under these conditions, with the CAT machine, what will be the estimated contractor's hourly production rate in LCY/ hr ? Make sure you list all correction factors used in the calculation with indicating where individual factor comes from (e.g., Average operator technique =x.xx, Material density correction =x.xx, etc.); otherwise, you won't get the full credit
