📐 1. Earthwork Cut & Fill Volume Calculation

In construction and land development, cut and fill volumes determine the amount of earth to be excavated (cut) or imported (fill) to achieve a desired grade. The grid method divides the site into cells, and for each cell, the average depth of cut or fill is multiplied by the cell area. This calculator supports custom grid sizes (up to 10x10) and multiple sections, with a color‑coded heatmap for easy visualisation.

Cut volume: Sum over cells where existing elevation > design elevation.
Fill volume: Sum over cells where design elevation > existing elevation.
Net volume = Cut – Fill (positive = surplus, negative = deficit).

📂 3. How to Use the Calculator

Select grid size (rows x columns). The grid will automatically generate input fields.
Enter existing elevation (top) and design elevation (bottom) for each cell.
Set cell area (m² per cell). Total area = grid cells × cell area.
Compute: Click "Compute Volumes" – cut/fill volumes appear, and the heatmap updates (red=cut, green=fill).
Batch CSV: Upload a CSV with existing elevations (space or comma separated) – one row per grid row.
PDF Report: Download a report with the heatmap image.
History: All calculations saved locally; export or clear anytime.

📈 4. Real‑World Example

Building site, Bangladesh
5x5 grid, cell area = 100 m². Existing elevations vary from 10.5 to 12.2 m, design platform at 11.5 m.
The calculator computes cut where existing > 11.5, fill where existing < 11.5. Net volume indicates surplus or deficit of soil.

❓ Frequently Asked Questions

❓ What is the grid method?

The grid method divides the site into cells. For each cell, the average cut/fill depth is multiplied by the cell area to obtain volume.

❓ How accurate is this calculator?

Accuracy depends on grid resolution. Finer grids give better results. For final design, use professional software.

❓ Is the tool free?

Yes, completely free. Batch processing supports up to 100 rows per CSV.
