Volume Calculation that adopted to find earthwork quantities for various civil engineering projects like:

• Road Work

• Irrigation Canal project

• Tank Survey

• Earth Moving

• And etc.

Earthworks - created through the moving and/or processing of massive quantities of soil or unformed rock.

Cutting - The process of excavating earth material from a work location to achieve the desired topography.

Filling - the process of moving the excavated material or additional earth material to a work location to achieve the desired topography.

Typically, earthwork is done in the following projects:

• Road works

• Railways

• Irrigation project such as canals and dams

• Other common earthwork applications are land grading to reconfigure the topography of a site, or to stabilize slopes

There are four popular methods of earthwork calculation:

• Section method

• Average method

• Division by Square method

• Contour method

• Preparing for Earthwork Calculation

• Finding the grid Levels

• Interpolating the Available Elevations at the Grid Points

▫ Weighted average

▫ Triangulation

Four different Volume calculation methods should be in practice

• Section Method

• Average method

• Division of Square method

• Contour Method

For calculating the volume, always two sets of surface data are required.

• Initial Level: Original Ground Level (OGL) (survey data)

• Final Level: Proposed/Designed Level (estimate) or Formation Level (survey data)

In trapezoidal method, each segment of the section is divided into various trapezoids and triangles.

• Trapezoidal Area A = 1/2 X a X (b1+b2)

• Triangle area A = a * b/2
