What is a correction factor?
Think about how we adapt numbers to reflect real conditions.
Why do soil density levels matter in dozing operations?
Recall how bulldozers interact with different materials.
What does a correction factor do in production estimates?
Think of how you adapt estimates to real-life conditions.
True or False: Job efficiency indicates the actual working minutes compared to total minutes available.
Reflect on what job efficiency means in practice.
A bulldozer is scheduled to work on a site with varying soil densities. If planned density is 1400 kg/m³ but actual is 1600 kg/m³, calculate the material weight correction factor.
Similar to previous examples; apply the same formula you used in class.
After adjusting for correction factors, the bulldozer's productivity has dropped to 50 m³/hour instead of the expected 80 m³/hour. How does this impact your cost estimations?
Consider how much more you'll need to charge with the new productivity figures.
