Analysis of Cost Overrun For Flyover Bridges Construction Project Using Fuzzy Logic

Abstract

Bridges Construction industry is measured as one of the most dynamic and risky industrial sector. Project failure takes place in terms of project delay, cost over runs and poor quality. In this project, I aim to identify and analyze the major cost overrun factors in bridge construction projects in Indore. The cost is measured as one of the most important success parameter of any project. The cost overrun factors are identified based on questionnaire survey and expert opinion which is ranked using Relative Important Index (RII) scale. Graphs showing the variation of cost overrun for different combination of cost overrun factors are obtained. This project work presents an application of fuzzy logic for developing cost overrun evaluation model using Fuzzy toolbox of MATLAB Program Software. This project work aims to identify the main factors affecting the construction cost overrun in the construction industries. A list containing 74 factors of cost overrun which are accountable for the cost overrun in the construction industries was prepared based on data collection, questionnaire survey and by conducting interviews. Finally, the model has been calibrated on real case study.
