Find here complete lessons of volume calculation (earthwork / takeoff) methods provided by Survey Drawing.

2. 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.

3. 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.

4. 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

5. There are four popular methods of earthwork calculation:
• Section method
• Average method
• Division by Square method
• Contour method

6. • Preparing for Earthwork Calculation
• Finding the grid Levels
• Interpolating the Available Elevations at the Grid Points
▫ Weighted average
▫ Triangulation

7. Four different Volume calculation methods should be in practice
• Section Method
• Average method
• Division of Square method
• Contour Method

8. 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)

9. 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
