- Calculate area of sections
- Multiply by distance
2. Average End Area Method
Where:
- A₁ = First cross-section area
- A₂ = Second cross-section area
- L = Distance between sections
Importance
- Cost estimation
- Material planning
- Project control
Conclusion
Accurate earthwork calculation ensures proper budgeting and execution.
