Yes. it is possible to calculate excavation volumes in several ways: Delta volume analytics allow users to calculate cut/fill volumes against any of the following surfaces: interpolated (average surface based on the elevation of the points the user used for the polygon/area of the volumetric calculation), minimum elevation inside the polygon, custom elevation (the user types in an elevation), any other date of model/design. Generate the volume grid and heat map report, which compares between any two surfaces such as two models from different dates or a model and an imported design. This professional report provides more detailed information such as grid cells, cut/fill volumes for each and every cell and the accumulative volumes in the calculated area.
