The material correction factor is 1.0. Assume slot dozing, and a 50 min/hr job efficiency. For weight, wet sand is pretty close to 2300 pounds per Cy. Excluding grade, what is my net correction factor for the other factors (excluding grade)?
Find the different correction factors for less than ideal
conditions.
a). Material – weight Correction Factor
CF = 2,300lbs/LCY / 2,300 lbs/LCY = 1
b). Operator correction factor
- by use table =0.75
c). Material – Type Correction Factor
- by given question = 1
d). Operating technique Correction Factor
- by use table = 1.2
e). Visibility Correction Factor
- by use table = 1.0
f). Efficiency Factor- 50 working minutes per hour / 60 minute
working hour = 0.83
g). Machine transmission factor
- by use table = 1.0
h). Blade adjustment factor
-by use table = 1.0
Determine net Correction factor
= 0.75×1.2×0.83 =0.747
