2. Estimating Unit Production Costs

Try these first

1. 1.

   Define unit production cost and its significance.

   Hint

   Think about how costs relate to output in construction.

2. 2.

   What is meant by cycle time?

   Hint

   Consider all phases of operation, from loading to unloading.

3. 3.

   What is the primary factor impacting operational efficiency?

   • Number of pusher
   • Cycle time
   • Volume per load

   Hint

   Review how cycle time relates to productivity.

4. 4.

   True or False: An increase in the number of scrapers will always improve productivity.

   • True
   • False

   Hint

   Consider the relationship between scrapers and pushers in production.

5. 5.

   Calculate the productivity difference between using 5 scrapers and an increased number of 7, considering the same cycle time and volume per load.

   Hint

   Compare the production rates you calculated for both setups.

6. 6.

   Discuss potential scenarios and operational adjustments needed if the unit cost rises significantly when increasing scrapers. What could you suggest?

   Hint

   Think about operational costs versus project timeframes.
