Earthwork Volume Calculation Methods

Earthwork Volume Calculation Methods

• 2.
  Volume Calculation thatadopted to find earthwork quantities for various civil engineering projects like: • Road Work • Irrigation Canal project • Tank Survey • Earth Moving • And etc.
• 3.
  Earthworks - createdthrough 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 isdone 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

  For calculating thevolume, 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) Read full article here: http://www.surveydrawing.net/earthwork-volume- section.html

  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 Read full article here: http://www.surveydrawing.net/earthwork-volume-trapezoidal. html
