How do you calculate excavation?
So, the formula is: Ab = Wb * Lb, where Wb and Lb are the width and length of the bottom of the excavation. At = Wt * Lt, where Wt and Lt are the width and length of the top of the excavation. In our example, Wb = Lb = 5 and Wt = Lt = 15, so Ab = 5 * 5 = 25 and At = 15 * 15 = 225, and D = 5.
Why is excavation so expensive?
It can cost $50-$200 per yard depending on local rates, the accessibility of the job site and its geology (soft soil, hard pan, boulders, etc), and whether the dirt excavated is left on site or hauled away. Prices can increase if the digging hits a rock shelf or other underground obstruction.
