How to Calculate Earthwork Quantity in Road Construction

Introduction

Earthwork calculation is important for estimating excavation and filling work.


Methods

1. Cross Section Method

  • Calculate area of sections
  • Multiply by distance

2. Average End Area Method

V=A1+A22×LV = \frac{A_1 + A_2}{2} \times L

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.
