Smart Web Application on Quantity Survey, Estimation and Costing

摘要

A construction project of any building is mainly based on 3 important steps, that are, Planning, Estimation & Costing for the building and construction/execution of the building. Estimation and costing is estimating the amount of material to be used and also calculating the approximate budget required for construction. Calculating the amount appropriately is very important to manage the costing. This estimation and analysis is mostly done manually. Maintaining high accuracy is very difficult at human level and even a small human error can cost a huge loss. Hence to eliminate the human errors and to enhance accuracy we are proposing a model in intelligent system. In this mode, input will be in the form of AutoCAD drawings (.dwg) from which dimensions will be extracted and converted to proper unit and will be used for calculation. This will reduce the human intervention to a large extent, thus minimizing the errors. The proposed model will estimate the amount of material used during construction such as sand, cement, concrete, bricks and all other materials and also will calculate real time cost, i.e. the total cost required to be spent on the material. Also the model will have a live database that will take input from the user, the real time costing of the material. The algorithm used will calculate material estimation and also the total cost for the materials, based on the dimensions extracted and quantities estimated. Hence the proposed model can help to eliminate human error while calculating estimates and can be used by a Contractor or a Builder to calculate total estimated cost and present it in the form of a detailed report which can be used for tendering purpose and negotiating a fruitful contract.
