With advancement of Technology there is a lot of progress in the way we take Ground reading. Earlier only Auto Levels were used, whereas now Total Station, GPS, LIDAR are being used to take ground reading. Previously Earthwork Calculations were simply done on paper followed by some simple computer applications. Now, however, either Spread Sheets likes Excel are used or advanced software products which are specifically designed for earthwork calculation are used. But volumetric calculations done by software still have to presented in understandable manner even while getting different results from different software products.
There are three different methods popularly used for doing Earthwork Calculation for Cutting/Filling Projects. Before discussing these in detail let us try to understand Some Basic definition of Terms related to Earthwork Calculation.
Earthworks are engineering works created through the moving and/or processing of massive quantities of soil or unformed rock. Earthwork is done to reconfigure the topography of a site to achieve the design levels. Earthwork involves cutting and filling to achieve the required topography.
Cutting is the process of excavating earth material from a work location to achieve the desired topography.
Filling is the process of moving the excavated material or additional earth material to a work location to achieve the desired topography.
