6.1. Project Requirements

Try these first

1. 1.

   What is the first step in earthmoving operations?

   Hint

   Think about what makes it easier to dig.

2. 2.

   Define Haul Distance.

   Hint

   What would affect the time it takes to transport material?

3. 3.

   What is the primary purpose of earthmoving operations?

   • To excavate soil
   • To manage water
   • To transport materials

   Hint

   Consider the main objective of the operation.

4. 4.

   True or False: Rolling resistance increases with poor maintenance of haul roads.

   • True
   • False

   Hint

   Think about how road conditions affect machinery.

5. 5.

   A contractor needs to excavate and haul 200 cubic meters of soil over a distance of 500 meters. Given the average rolling resistance of 75 kg per ton, calculate the total required effort if the machine weighs 25 tons.

   Hint

   Consider each component of resistance carefully.

6. 6.

   Discuss the potential impacts on project timelines if the equipment selected does not match the haul distance requirements. What management steps could be taken to mitigate these impacts?

   Hint

   Think about logistics and time management.
