Abstract - The growth of Tunnel Construction industry
increased, as has the rising pressure to reduce costs and shorten construction time.
made significant improvement over the past few decades. “Safety First” should be one of the main objectives of any construction projects mainly tunnel and shall be given high priority throughout the construction period. This many a times lead to the incompletion of these projects, and ultimately its cost overrun and time overrun. This study aims to bring out the safety measures taken by the management towards the construction workers involved in the tunnelling works. This research involves literature study through reviewing various journal papers and data collections regarding the tunnel workers safety and case studies on various metro tunnel projects and accidents happened during the construction. The outcome of this study is to come up with the proper managing tools for the safety managers towards the safety of the workers and identifying the risk factors in the construction phase and also suggesting some risk mitigation measures and techniques to avoid such accidents in future.
2. AIM AND OBJECTIVES The main objective is to assess and manage the risks associated with tunnelling projects in India, as well as to determine the probability and severity of risks involved in various phases of the project, analyze the risks, and offer risk mitigation methods for the principal hazards included in the project. Determine the primary internal and external risks that the tunnel construction industry's development is most vulnerable to risk assessment in order to rank them for effective risk management. The development of a risk management strategy that incorporates appropriate measures to reduce tunneling-related hazards.
3. METHODOLOGY The first step will involve conducting a thorough review of relevant literature on metro tunnel projects, construction safety, and best practices in ensuring safety for construction workers in tunnel projects. This literature review will provide a comprehensive understanding of the current state of research on the topic, identify research gaps, and provide a foundation for the research.

1. INTRODUCTION Tunnelling is commonly used in the construction of railways, roads, and irrigation systems. Tunnelling engineering specialisation is a major risk factor during project implementation. Tunnelling and subterranean construction projects entail risks to all parties concerned, including those who are not directly involved in the operation. The impact has been significant, particularly in residential areas. Influence the local population as well as neighbouring structures. Among the inherent threats are ground and groundwater concerns. There are also conditions, cost overruns, and major accidents. There is a risk that the tunnel project could cause public protest, which could have an impact on the project. Typically, these dangers are mitigated by employing appropriate risk assessment and mitigation measures. However, a lack of appropriate risk management approaches in our country has resulted in many project cost and time overruns. Implementing risk assessment and the need for management in the tunnel construction sector has grown over time as the complexity of tunnelling projects has

The second step will involve conducting case studies of metro tunnel projects from different regions of the world to identify and compare different safety measures implemented in these projects. The case studies will include interviews with project managers, construction workers, and safety officers to gain insights into the various safety measures implemented and their effectiveness in ensuring worker safety. The third step will involve conducting gathering data on the current safety measures being implemented in metro tunnel projects. This will be designed to gather information from construction workers, supervisors, and project managers involved in metro tunnel projects. This will focus on the types of safety hazards encountered in metro tunnel projects, the current safety measures being implemented, and the effectiveness of these measures in ensuring worker safety.
