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.
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
- Cut and fill volumes from irregular survey data

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 sloped plane, or a second surveyed surface.
