What You Can Calculate
Our earthwork calculators help you estimate excavation quantities in three states: bank cubic yards (in-place soil), loose cubic yards (after digging), and compacted cubic yards (after compaction). Select from eight soil types with standard swell and shrink factors based on USCS soil classification.
Common Applications
- Foundation and basement excavation
- Trench digging for utilities and drainage
- Site grading and cut/fill analysis
- Dump truck load counting and haul-off planning
- Compacted fill requirements for building pads
Disclaimer: All calculators provide estimates for planning purposes only. Soil behavior varies with moisture, density, and site conditions. For structural excavations or trenches deeper than 5 feet, consult a licensed geotechnical engineer and follow OSHA 1926 Subpart P requirements.
