# How Do You Estimate 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.

### Excavation Costs

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.

Land grading costs \$17,400 to \$43,600 per acre, depending on the site conditions, slope steepness, and fill dirt or topsoil needed. The cost to level a 1/4-acre home lot is \$4,400 to \$10,900. Most residential grading projects are 1/4 acre or less.

### How to Calculate Backfill

1. Calculate the volume of the space to be filled. …
2. Calculate the cubic yardage of the same trench. …
3. Next you might need to fill a round hole that is 10 feet in diameter and 5 feet deep. …
4. Estimate the number of truckloads that will be required to fill these two holes with backfill.

### What costs make up the cost of labor?

The cost of labor is the sum of all wages paid to employees, as well as the cost of employee benefits and payroll taxes paid by an employer.

### How do you calculate labor cost in construction?

Usually, you can find that number by dividing the indirect costs by the direct costs and multiplying that number by 100%. To satisfy our fellow numbers nerds, here’s the formula for calculating labor burden: Indirect Costs / Direct Costs x 100% = Labor Burden.

### How is Earth’s filling quantity calculated?

Area of the plot = Length x Width = 40 x 30 =1200 sft. Suppose we need to fill the plot by 3’5” = 3.41 feet. ∴ Depth of the plot = 3.41 feet. Volume of plot to be filled = 1200 x 3.41 = 4092 cft.
