Excavation Volume Calculator
Quickly estimate the soil volume for trenches or pits using recommendations from IS 3764:1992 (Code of Safety).
Formula: Volume = Length × Width × Depth
About Excavation (IS 3764 Highlights)
- For excavations deeper than 1.5m, provide shoring, sloping, or benching to prevent collapse.
- Keep excavated soil and materials at least 1/3 the trench depth or 1m from the edge.
- Mark and avoid underground utilities before digging.
- A competent supervisor must inspect excavations daily and after rainfall.
Common Types of Excavation
- Topsoil Excavation: Removing fertile upper soil layer.
- Earth Excavation: Removing subsoil for foundations, bridges, or roads.
- Rock Excavation: Blasting or drilling hard rock layers.
- Trench Excavation: For pipelines, cables, drainage works.
- Basement Excavation: For below-ground structures, needing special care.
Key Excavation Hazards
- Cave-ins: Sudden collapse of trench sides; often fatal.
- Contact with utilities: Striking electric cables or pipelines can cause serious injury or flooding.
- Falling tools/equipment: Keep all equipment away from excavation edge.
- Water ingress: Flooding from rain or broken water lines can destabilize excavations.
Essential Safety Tips
- Always use barricades around excavation sites.
- Provide safe entry/exit (ladders, ramps) for deep excavations (>1.2 m).
- Never allow loads or vehicles near trench edges.
- Wear personal protective equipment: helmets, gloves, reflective vests.
- Check atmospheric quality before entering deep excavations.
