The Excavation Quantity Calculator estimates the volume of earth needed for footings. It helps with project planning and resource management.

To use the calculator, input the number of footings, their length, width, depth, and the excavation angle. The tool calculates the volume for each footing and provides the total excavation quantity.

The calculator uses a formula for the volume of a truncated pyramid. This accounts for sloped sides and gives accurate results. It adjusts the top length and width of the excavation based on the angle of the slope. The excavation angle can range from 0 to 75 degrees. A 0 degree angle means exactly vertical excavation, while 75 degrees means excavation line makes 15 degree angle from the ground.

The results are given in cubic meters (cum) and cubic feet (cft). This makes it easy to switch between measurement systems. The calculator helps you order materials, plan labor, and avoid construction errors.
