Earthwork volume calculation

This document discusses about the industry practices of various methods of volume calculation so that the readers can finally choose the right one for their project. In this method, volume of cutting or filling is found out for each block and added together to get the final volume. But volumetric calculations done by software still have to presented in understandable manner even while getting different results from different software products. Previous Issues Subscribe Now. Before discussing these in detail let us try to understand Some Basic definition of Terms related to Earthwork Calculation.

Quality Testing Instruments from Industria Triangulation of existing terrain. But volumetric calculations done by software still have to presented in understandable manner even while getting different results from different software products. Example 1 Only Cutting: Example 2 Both Cutting and Filling.

This method is more accurate, but for larger area, finding the area becomes difficult caculation we need to find intersection of points where lines representing Surfaces meet. Before discussing these in detail let us try to understand Some Basic definition of Terms related to Earthwork Calculation.

Home Publication News Tech. Previous Issues Subscribe Now. One of calculqtion great advantages of this method is that cross sections are generated in the process. From these depths the volumes of each grid cell can be calculated, and by adding the cell volumes together the total cut and fill volumes are obtained.

There is a wikipedia page which compares the different software for earthworks estimates here. An advantage of the grid method are that the basis of the estimate can be fully summarised on the site drawings, which presents a very clear summary of the calculations for others to check. Cutting is the process of excavating earth material from a work location or borrow pits to achieve the desired topography.

Earthwork involves cutting and filling to achieve the required topography. We often get asked how earthworks volumes are calculated in our software. Due to the great complexity of these calculations and the thousands of triangles that are generated it is not practical to calculate triangular prisms by hand.

But this can be used only when there is cutting or filling.

Once the volume has been calculated for each grid cell, all of the cut cells are added together to obtain the total cut volume. These values can be used to calculate the cut and fill for each triangle, and the total volumes are easily obtained by esrthwork all the triangles together.

For each section line the cut area and the fill area is determined. 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 Earthwork Calculation Methods: This step is repeated for the proposed terrain.

Then volume is determined by multiplying Average Area with Distance between Sections. The next stage is to merge these two triangulations, to create a third triangulation which contains all the edges of the original triangulations. The spreadsheet included with this article includes formulae which have automated the process of calculating section areas using the trapezoidal rule. Further, all the calculations are done depending upon these values.

Complex examples take a lot of time to solve and it is advised to use any software for such purposes. This method starts by triangulating the existing terrain.

Cutting Cutting is the process of excavating earth material from a work location to achieve the desired topography. In this method Sections are drawn for Each Line of Value.

This calculation is repeated for all of the sections, and the values are added together to get the total cut and fill volumes.

An example calculation of the volume for one of the grid cells in the example above. You must be logged in to post a comment.
