An Assessment of Environmental Impacts of Building Construction Projects

Abstract

The environment is threatened severely by so many problems, some of which are caused by the activities of Construction Projects. The global concern to address environmental degradation caused by various developmental actions (construction projects inclusive) is the basis for calls to assess environmental impacts of building construction projects in Nigeria. Data for the study were collated through a questionnaire survey administered to stakeholders of Nigeria’s building construction industry. Data collected were analysed and ranked using Relative Importance Index (RII), result shows impacts listed are above the mid (RII) index of 3.0 suggesting that they significantly impact on the environment thereby causing environmental degradation. The research also reveals major environmental impacts of building construction projects to include environmental pollution, resource depletion and habitat destruction causing Destruction of ecosystem, Desertification, Soil Erosion and increasing Material Wastage. Waste Management, Pollution Control and Ecology Conservation were ranked as the most important environmental protection measures used in controlling building construction environmental impacts. The study therefore suggest that in order to reduce environmental degradation, building construction stakeholders must adopt fully environmental impact assessment document and other regulations relevant for environmental protection. Also, all environmental regulatory agencies and sensitization organizations should continuously sensitize the building construction public on requisite environmental management practice and sanction erring agents.
