How does the type of soil to be excavated affect the estimate?
What will be an ideal response?
The type of soil affects the estimate by:
The amount of swell varies for each type of soil affecting the amount of soil that needs to be used as backfill or hauled away.
The type of soil also affects the slope at the sides of the excavation. This affects the amount of soil that must be excavated, backfilled, and will determine whether bracing or piles will be required to support the sides of the excavation.
The type of soil may also affect the type of equipment selected for the excavation and how long it will take to perform the work.
