In this method Sections are drawn for Each Line of Value. Note: Although in this example there is some cutting, because of nullification of value in same block we are not getting any value in Cutting. Note: Value 0.61 = Average (192.51, 193.71, 193.04, 193.14) – Average (191.9, 193.1, 192.43, 192.53) [Values taken from first 2 rows and 2 columns of ground and formation level)Įxample 2 (Both Cutting and Filling) : Difference in Average for Each 10 X 10 Block But here the margin of error is very small when compared to Average method for whole area.Įxample 1(Only Cutting): Difference in Average for Each 10 X 10 Block The problem of nullification is also encountered here when in the same block there is both cutting and filling.
This is mathematically simpler then Section Method, but more accurate than Average method. In this method, volume of cutting or filling is found out for each block and added together to get the final volume. Volume = Average * 900 = 0.606 * 900 = 545.62īlock Method (Division of Square Method): When Leveling of surface includes both cutting and filling, Average method gives wrong result as cutting and filling values nullify each other while averaging. But this can be used only when there is cutting or filling. This is a very simple and straight forward method. Difference between the Average of Two Sets of Levels multiplied by Area gives the Result. In this method Levels at each grid point is found out. Let us take 2 Simple Examples for our Study In the Example below the plot is 30 X 30 Meters and all the Grid levels measured at Grid level of 10M Earthwork involves cutting and filling to achieve the required topography.Ĭutting is the process of excavating earth material from a work location to achieve the desired topography.įilling is the process of moving the excavated material or additional earth material to a work location to achieve the desired topography.
Earthwork is done to reconfigure the topography of a site to achieve the design levels. Before discussing these in detail let us try to understand Some Basic definition of Terms related to Earthwork Calculation.Įarthworks are engineering works created through the moving and/or processing of massive quantities of soil or unformed rock. There are three different methods popularly used for doing Earthwork Calculation for Cutting/Filling Projects.
#EARTHWORK QUANTITY TAKEOFF EXAMPLE SOFTWARE#
But volumetric calculations done by software still have to presented in understandable manner even while getting different results from different software products. Now, however, either Spread Sheets likes Excel are used or advanced software products which are specifically designed for earthwork calculation are used. Previously Earthwork Calculations were simply done on paper followed by some simple computer applications. Earlier only Auto Levels were used, whereas now Total Station, GPS, LIDAR are being used to take ground reading. With advancement of Technology there is a lot of progress in the way we take Ground reading. Transportation - Metrorail / Airways / Waterways.
