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.
A typical residential excavation job runs between $1,449 and $5,313 with an average of $3,317. Though most companies charge anywhere from $40 to $150 an hour, residential jobs receive project bids. Project bids reflect cubic yards of dirt moved, anywhere from $50 to $200 per cubic yard.
Why is excavation so expensive?
A good contractor owns their own equipment. So, residential excavation costs help cover the man hours, cost of purchasing the equipment, and transportation and maintenance. These large machines can be quite expensive, which is why the excavation team needs to charge appropriately to cover the expenses.
For a 4 hour job the trucking cost is probably much higher than the actual rental of the hoe. I think your $150 an hour is close for a 325. I would use $250 as an average for the excavator and $210 for transport.
