Earthwork volumes from survey points: cut, fill, and isopach map
From total station survey points the tool builds a TIN surface and computes cut and fill volumes against a design elevation or a second surface. Output includes the earthwork balance, contour lines, and an isopach map with a quantity schedule.
Data current as of 2026-08-24
Standards
TIN method (Delaunay triangulation), verified against analytical solids to 10⁻⁶ accuracy. Grid method and cross sections are available for regular surveys.
Input
X, Y, Z points from Excel or CSV. Design elevation or a second surface.
Output
Cut, fill, balance, isopach map, quantity schedule.
What it does

Questions
What kind of survey works?
Any irregular total station survey: TIN does not depend on grid orientation. A grid method is available for gridded surveys.
How is the base surface defined?
By a design elevation, a second surveyed surface, or an excavation design with side slopes.
What is free?
Volumes to a plane or between two surveys up to 500 points with the on-screen cut-fill map. The full feature set is shown in the built-in example project.
