Given: The Figure shows the calculation for a pit to accommodate a structure of size ${36}^{\text{'}}{0}^{\text{'}\text{'}}{32}^{\text{'}}{0}^{\text{'}\text{'}}$ in soil that is not hard and compact, so the sides of this excavation are cut back to a $1$:$1$ slope.

Required: Takeoff the volume of Pit Excavations, the backfill and the dispose of surplus. Consider that the excavated soil is not recommended for the backfill.
