What is the primary purpose of applying correction factors to bulldozer productivity estimates?
💡 Hint: Think about why we would need to change ideal assumptions.
True or False: A higher soil density always decreases bulldozer productivity.
💡 Hint: Consider the work the bulldozer has to do based on material weight.

Challenge Problems
Push your limits with advanced challenges
During a bulldozer’s operation, the soil density was unexpectedly high, leading to a productivity drop to 70 loose meter cube per hour. If correction factors led to a 15% lower output from the estimated 100 loose meter cube per hour, calculate the adjustment made.
💡 Hint: Think about re-calculating with factors that affect the productivity further.
An excavation project requires calculating the total cost given a bulldozer with a unit cost of Rs. 26.06 per bank meter cube was used for 200 bank meter cubes. Calculate total project cost.
💡 Hint: Focus on simple multiplication for total project expenses.
