4.3. Productive Dozing Methods

Try these first

1. 1.

   What is a correction factor?

   Hint

   Think about how we adapt numbers to reflect real conditions.

2. 2.

   Why do soil density levels matter in dozing operations?

   Hint

   Recall how bulldozers interact with different materials.

3. 3.

   What does a correction factor do in production estimates?

   • Increases productivity
   • Decreases productivity
   • Adjusts productivity based on conditions

   Hint

   Think of how you adapt estimates to real-life conditions.

4. 4.

   True or False: Job efficiency indicates the actual working minutes compared to total minutes available.

   • True
   • False

   Hint

   Reflect on what job efficiency means in practice.

5. 5.

   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.

   Hint

   Similar to previous examples; apply the same formula you used in class.

6. 6.

   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?

   Hint

   Consider how much more you'll need to charge with the new productivity figures.
