Calculation of Cut and Fill of Earthworks with Quantum-GIS

The work of cut and fill is the first step in any earthworks. So it is very necessary for any contractor to carry this work with full precautions and complete the work without any errors in the calculation. The road works or the drainage constructions are very important constructions as it shows the economy of a country. It beautifies the surrounding of a place. If the construction of such structures is done properly then it may lead to severe accidents and other major losses may occur. It is necessary for all the earthwork contractors to calculate the proper and accurate estimate of earthwork. If the estimate of earthwork done by contractor is not accurate then he will be unable to assign the proper construction assets he cannot formulate a project schedule as well. There are many unknowns and assumptions required in estimating the earthwork construction. And this is the reason that while doing this task the contractor is at greatest risk. The Project of river interlinking need lots of information. The selection of paths through which two rivers should be interlinked is very cumbersome and time consuming. But the same process will take very less time if it is done with the help of GIS in the software Quantum-GIS. The major problem in interlinking of two rivers comes when the proper path is to be selected. Less the undulations, more will be the suitability of the path. But if there is some suitable path with more undulations then the construction work is increased. By construction we mean the work of cut and fill. This cut and fill must be done in appropriate manner so as to make the project successful. Quantum-GIS help in calculating the total cut and fill through certain formula. In this paper we will be discussing the analytical solution of cut and fill through Quantum-GIS. The same procedure can be done while doing road work or drainage work. The software reduces some amount of manual work and hence time is saved.
