AHP Framework for Prioritising Risk Factors in Bridge Construction

With increase in scale of road construction in India, it has become increasingly difficult to assess the timely completion of bridge construction. The major issue for delay is poor management of associated risks on projects. Moreover, the complexity of bridge projects further adds variety of risk factors. It is important to concentrate only on most significant risk factors which are having highest impact on timely completion of project. In this work the author brought an Analytical Hierarchical Processes (AHP) approach to identify most significant risk factors on bridge construction which are responsible for delay. Around 25 bridge case studies are considered for work. The long list of risk factors is formulated through repository of literature and bridge expert’s opinions. In the framework initially risk factors are divided in 3 level hierarchy for eliciting weightages. Then, the matrix is prepared using the pairwise comparison and the final weightages are obtained through AHP procedure. These weights are further used for prioritisation of risk factors. The main intent of this work to produce robust framework in prioritisation of risk factors predicted in bridge construction.
