Costing Estimation and Scheduling of 60m ECC Box Girder Bridge Over Man Khad Barsar HP

Abstract

In this project the Estimation and Costing of a 60 M span box Girder Bridge over Man khad on jeoli devi , Saheli, Bhebar Karsai, Joure Amb Road has been done. The bridge consists of two spans of 30M each. And in the Project Part I the estimation of the foundation as well as the sub structure has been done. The purpose of this project is to basically learn the technique of estimating the quantity of concrete as well as the steel used in the structure. Along with the costing and estimation, rate analysis for the entire bridge has been done as per the items state in the BOQ for the respective bridge work. The rate analysis is extremely helpful to know the expected cost of a project which is further helpful for the construction firms at the time of bidding for a particular tender. The entire project has been summed up by comparing the estimated quantity of the concrete and the steel used with the quantities given in the BOQ of the work. The project has been complete using software’s like MS Excel 2010 using the format for the Rate Analysis, Estimation of concrete and the Estimation of the quantity of steel has been done. The drawing to show the cross sectional and the dimensional details of the have been prepared using AutoCAD. In the analysis of the Rates the entire cost has been divided into four parts i.e. cost for labour, cost of material, cost of machinery and in some cases cost of carriage has also been taken into consideration. Whereas in the estimation. The estimation has been done in two parts the estimation of the quantity of steel and the estimation of quantity of concrete has been done separately. And in the end the abstract has been prepared to summarise the total rate of the project, total amount of concrete used and the total amount of steel used. In addition to this the amount of backfill and the amount of filter media used has also been calculated.
