2. Estimation of Unit Cost

Try these first

1. 1.

   What is a correction factor?

   Hint

   Think of it as a way to modify ideal estimates.

2. 2.

   Define productivity in the context of construction.

   Hint

   How fast can you move earth?

3. 3.

   What is a correction factor?

   • A constant value
   • A quality control measure
   • A multiplier for productivity adjustment

   Hint

   Think about how we modify ideal conditions.

4. 4.

   True or False: Higher soil density typically leads to higher productivity.

   • True
   • False

   Hint

   Think about how much easier it is to dig in sandy soil.

5. 5.

   You have a bulldozer estimated productivity of 150 units/hour but face adverse conditions bringing a correction factor down to 0.6. Calculate adjusted productivity and unit cost, assuming total costs of 2000 rupees/hour.

   Hint

   Don’t forget to multiply before dividing!

6. 6.

   Design a scenario in which multiple correction factors are applied, and analyze how each contributes to a final productivity calculation.

   Hint

   What happens when you multiply all together?
