Carlson Takeoff is a CAD-based software solution designed for earthwork volume calculations, takeoff, and 3D modeling in construction and civil engineering. It enables users to estimate cut and fill volumes, subgrade quantities, trench and pipe quantities, and roadway volumes using data from paper plans, PDFs, or electronic CAD files. The software supports both layout preparation and machine control modeling, and is compatible with most GNSS, total stations, and machine control systems. It can be used standalone with IntelliCAD or integrated with AutoCAD, and is suitable for contractors, engineers, and surveyors needing accurate site modeling and quantity takeoff.
