Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Cross-section area = (top width + base width) ÷ 2 × height. Multiply by length and berm count, then add the entered compaction and grading allowance.
FAQ
Berm Volume Calculator questions
Why is the berm modeled as a trapezoid?+
A trapezoid represents a flat or rounded working top with sloped sides using simple measurable widths. Irregular profiles should be split into sections.
What does the compaction allowance represent?+
Loose delivered soil occupies more volume than compacted placed soil and grading creates handling loss. Use a project-specific allowance based on the material.
Does the calculator choose a safe side slope?+
No. Soil type, saturation, height, erosion and site constraints determine slope stability and may require professional evaluation.
