Health and Safety Hazard Identification and Risk Assessment of Underground Cross Passage Construction in Between Two Metro Tunnels and Physicochemical and Microbial Assessment of Tap and Filtered Water in Academic Zone of NIT Rourkela

Abstract

Th construction industry is an important contributor to the nation growth in terms of gross domestic product (GDP) and employment opportunity. Owing to its relatively labour intensive nature, construction works provide opportunities for employment for a wide range of people skilled, semi-skilled and unskilled. Despite its importance, construction industries are considered dangerous to work with as accidents rates, illness and injuries to workers, employees and public are increasing day by day. However, knowledge on how health and safety risks are managed on construction sites is limited. This study therefore, aims to study the current practice of health and safety risk assessment, risk communication and risk control at Delhi Metro Railways Corporation (DMRC) CC-27 site and to prepare a Risk assessment, communication and control procedure which can be applied to all the activities in the project site. In pursuing this objective, a detailed study on different procedure on health and safety risk assessment, communication and control being followed at different industries was studied and analyzed. A suitable procedure best suited to the Underground metro station construction project was proposed and validation was also done with the underground cross passage construction in between two metro tunnels. Lastly a suitable table for hazard identification and risk assessment (HIRA) and Safe Work Method Statement for the cross passage construction activity was also presented
