Development of a Risk Management Framework for Tunnel Construction in India

Abstract

The growth of Tunnel Construction industry made significant improvement over the past few decades. This is fundamentally due to the increasing investments in road, rail and hydropower sectors. However, the tunnel construction industry in our country faces many challenges. This many a times lead to the incompletion of these projects, and ultimately its cost overrun and time overrun. A successful tunnel project is possible only if the risks associated with the project are identified, evaluated and managed. The main objective of this paper includes risk assessment and management of tunneling projects in developing countries like India. The procedure followed in this paper involves risks identification through literature surveys and interviews with experts, preparation of risk questionnaire to determine probability and severity of risk involved in various phases of the project, analysing the risks and suggesting risk mitigation measures for the major risks involved in the project. Case studies are also carried out to give a better insight in to the study.
