Free calculators for the estimator's bench.
These calculators do the geometric math that goes into a takeoff: cut and fill, earthwork volume, concrete yardage. Each one toggles Imperial and Metric, runs offline once loaded, and points at the Vertigraph product that does the full job from your drawings.
