Identification and Assessment of Environmental Risks Factors in Building Construction

Abstract

The requirement of the shelter is essential for the sustenance of the dynamism of livelihood of human being, and it lead to urbanization. The urbanization results in concentration of human population in a smaller area, densify the construction of buildings for living and other civic purposes and other constructions to fulfill the needs of the human being such as, water supply, drainage system, roads, power generation units and many more. The construction activities of all these facilities impacts negatively on the environment. The environmental risk is the probability and consequence of an undesirable impact due to the human interventions in natural processes. The overall scale of construction activities are extremely high and the same is its impact on various elements of environment. In the presented study the four elements of environment, i.e. human health, general atmosphere, ecology and society, on which the impact takes place due to building construction activities are taken into consideration. A total of nine factors and the forty sources are considered for finding out their ranking, with the help of questionnaire survey, in which 102 construction professionals participated. The five point Likert scale is used for probability and impact and analyzed by using the weighted score approach. The outcome of the analysis gives the risk factors and their sources for four elements, which have the highest probability and the impact of occurrence. The ranking of the risks perceived are obtained through analysis.
