Excavation Volume Calculator
Estimate bank and loose excavation volume from station sections using the average end-area method.
What would you like to do next?
Calculate volume between changing site sections
Enter station distance, average width and average depth for each section. The calculator sorts stations, derives a rectangular section area and applies the average end-area method between consecutive positions. Bank volume is totaled before an editable swell allowance creates a separate loose-volume planning quantity.
Replace simplified sections with controlled survey data
Actual excavations can include side slopes, benches, shoring, rock, unsuitable material, structures and overbreak. A width-times-depth section is only an early approximation. Use current survey surfaces, geotechnical classifications, design lines, pay-item rules and approved safe excavation methods for project quantities.
Frequently asked questions
Are stations sorted automatically?
Yes. Valid station values are sorted before volume calculation.
Which volume method is used?
The average end-area method is applied between adjacent sections.
Are side slopes included?
Only if their effect is already represented in the entered average width.
