3.3. Productivity Calculation

Try these first

1. 1.

   What is a correction factor?

   Hint

   Think of it as a way to adjust your calculations.

2. 2.

   How is job efficiency defined?

   Hint

   Consider the ideal time versus the actual time of operation.

3. 3.

   What is the primary purpose of applying correction factors in productivity calculations?

   • To increase theoretical productivity
   • To adjust ideal productivity to actual project conditions
   • To eliminate the need for calculations

   Hint

   Think about why projects may not meet ideal conditions.

4. 4.

   True or False: An operator's skill level can impact the productivity calculation.

   • True
   • False

   Hint

   Consider if an inexperienced operator would perform at the same level as an experienced one.

5. 5.

   A bulldozer is expected to operate on soil with a density of 1600 kg/m³, while the ideal curve is for 1365 kg/m³. Calculate the necessary correction factor and its impact on a productivity estimate of 80 loose cubic meters.

   Hint

   Always convert densities to see how they affect productivity.

6. 6.

   If the budget for operating a machine is Rs. 1500 per hour and the estimated productivity is 60 bank meter cubes, what would be the new cost per bank meter cube if the hourly cost rises to Rs. 1800?

   Hint

   Reassess your budget and divide by the productivity to find costs.
