Towards sustainability practices deployment in building construction projects in Nigeria

Abstract

PurposeWith recent extreme weather change from global warming, the ever-increasing volume of waste, and the unsustainable use of natural resources, there is the need to evolve a new way by which building construction projects are constructed to reduce carbon emissions, environmental degradation and excessive resource consumption. It is based on this premise that this paper presents the level of implementation of sustainability practices during building construction projects in Nigeria.Design/methodology/approachThis study adopted the mixed methods research approach that involves collecting quantitative and qualitative data through the use of questionnaire and interviews. The numeric data were analysed using descriptive and inferential statistics such average percentages, mean item score, Kruskal–Wallis and Mann–Whitney U tests whereas the textual data were analysed thematically.FindingsFrom the questionnaire survey, the result shows that the awareness level of sustainability practices by construction professionals is high in the study area. Also, the findings indicate that “choosing the right construction method for resource conservation and consideration of the client’s satisfaction” is the major sustainability practices that construction professionals implement in the construction phase of building projects in the study area. Insights from the interviews align with the findings from the questionnaire survey.Originality/valueThis study concluded that the awareness level of sustainability practices is high in the study area and “choosing the right construction method for resource conservation” and “consideration of the client's satisfaction” are the major sustainability practices that construction professionals are aware of and is being implemented in the study area. Based on these findings and conclusions reached, it is recommended that construction professionals should improve their knowledge of sustainability to enhance their competence for the effective implementation of sustainability practices during building construction projects in Nigeria.
