A CAT D8 power-shift dozer is used in a pushing operation. The dozer is equipped with a U blade. The material non-cohesive, dry silty sand weighs 106 pcf in the bank state. It is estimated that the material will swell 8% from bank to loose state. The center-of-mass–to–center-of-mass pushing is 350 ft on a -10% grade. The operators have average skill. The job will be performed in good visibility Job efficiency can be assumed to be equivalent to a 45-min hour. Calculate the direct cost of the proposed earthmoving operation in dollars per bcy. The normal O&O cost for these machines is $126.00 per hour and the operator’s wage is $31.00 per hour plus 35.0% for fringes, insurance, worker’s compensation, and so on.
