2.1. Calculation Methodology of Unit Cost

Try these first

1. 1.

   What is a correction factor?

   Hint

   Think about what factors might affect a bulldozer's efficiency.

2. 2.

   How do you calculate unit costs?

   Hint

   Recall the formula we discussed in class.

3. 3.

   What is the primary purpose of applying correction factors in construction?

   • To increase costs
   • To modify productivity estimates
   • To simplify calculations

   Hint

   Think about the conditions under which machines operate.

4. 4.

   True or False: The unit cost is the total cost divided by the volume of bank cubic meters moved.

   • True
   • False

   Hint

   Focus on what unit cost means.

5. 5.

   A bulldozer's ideal productivity is 120 loose m³/hr. However, due to a combination of factors resulting in correction factors at 0.6, what will the actual productivity be?

   Hint

   Think about how to apply the correction.

6. 6.

   If the owning and operating costs sum to 2000 rupees per hour and the productivity is 50 bank m³/hr, what is the unit cost?

   Hint

   Divide total costs by productivity.
