Dozer Hrs Calc:Total Hrs required to complete Project = Volume required to be moved x Production

Production = Max. Production x Correction Factors

1 Ramp Slope = 1% down hill1 Grade Correction = 1

0.75 Operator capability = Average0.83 Job Efficiency = (50min/hr)

19500 Total volume to be moved = 19,500 m3Dozer available = D11Max. Dozer distance = 100mDozer Blade = Semi Universal

600 Dozer Max. Productivity = 600Lm3/hr

Production = Max. Production x Correction Factors= 600 x 1 x 0.75 x 0.83= 373.5 Lm3/Hr

Volume Required to be Moved = 0.3 x 65000= 19500 m3

Total Hrs required to complete Project = Volume required to be moved x Production= 19500 / 373.5= 52.2088

62.6506 (safety factor = 1.2)

Total Days @ 9 hrs per day production = 5.80098
