Environmental risk Assessment Modelling of Construction Projects

Abstract

India lives in villages , however the trend is changing. The level of urbanization increased from 28 percent in the 2011 census to 31 percent in the 2021 census. The migration towards the urban area imposes negative impact on urban area such as natural resource depletion from surrounding, environmental pollution, earning disparities, redundancy, urban expansion, social unrest, population crowding etc. The protection of the environment is the matter of utmost concern to achieve the sustainable development goals, if not dealt scientifically and logically would impact ecosystems within the boundary of urban area as well as outside it, with implications for the quality of life of people. The construction is one of the main source of environmental pollution. The construction activities affect the environment negatively throughout the life cycle of the constructed building, starting from period of construction period, period of its use to its demolition at the end of its service life. Although the period of construction of building is too less in comparison to its useful life, but the activities in short time impose significant impact on environment. The construction projects contributes to economic and social developments, however their detrimental effect on environment needs proper attention. The construction of building have massive direct and indirect impact on environment which occurs due to various atmospheric emissions, liquid, dust and solid waste and many more reasons. newlineThe sustainability is a new concept for the building construction industry in all developing countries like India. There are no explicit comprehensive references by the law enforcing agencies at local, state and national level to the building planners, designers and contractors. It create huge challenges for urban local bodies for maintaining the environmental quality without compromising the safety and quality of life of people. This study is aimed to ascertain the priorities of various factors impacting the newlinePh.D. Thesis : Environmental risk A
