How do you calculate excavation volume? To calculate the total excavated volume of a project, the entire project is divided into several horizontal layers. The area of a typical excavated cross-section in a horizontal layer is calculated and multiplied by the thickness of the layer. Benching (Benching system) means a method of protecting
