SiteWork Earthwork and Utility Take-off Software works with PDF and CAD files, or from paper plans using an optional digitizer. It calculates cut and fill, stripping, strata quantities, paving and concrete materials, topsoil re-spread, areas, lengths, trench excavation, and backfill. 3D Live can be used to visualize the site from the operator’s vantage point, and see live updates of 3D during modeling and export models to various machine control systems.
