Risk identification in tunnel construction project: A literature review

Every construction project is always faced with the possibility of various occurrence kinds of risks. The higher the level of complexity of a project, the greater the level of risk that might happen to the project. Based on historical data from tunnel construction many problems and even failure of tunnel construction caused by various factors has been noted and it can have an impact on project delays. A risk management is expected to reduce the adverse impact of risks faced during construction work. Tunnel construction needs management handling with high risk, so it is necessary to identify risks that can minimize bad risks. A risk management is expected to reduce the adverse effects of risks faced in a construction work. It is necessary to perform risk identification to manage the risks that we will face. To successfully improve the performance of tunnel projects, we need to identify various risk factors in a project for efficient project fulfillment. The research method begins with an extensive literature review by reviewing at least 48 journal, journal papers, review articles to provide a list of the main risk factors which are also added to the expertise to achieve a list of final risk factors that contain all risks that may be encountered during road construction. This analysis involves the identification, classification of various risks involved in the construction of a tunnel construction project.
