Investigation of Construction Waste Generating Factors in Bangladesh

Abstract

In Bangladesh, construction waste is increasing day by day due to rapid urbanization and development works.  As a result, the construction development works faced negative impact on project due to excessive waste generation. In addition, the construction industry cannot function if its resources are wasted; therefore, waste identification and management are required. Considering those matters, this study aims at identifying the construction waste generating factors and construction waste management strategies for the construction industry of Bangladesh. This study used correlated literature to identify 28 significant waste generating factors. Then conducted survey on the Likert scale basis and prioritized the waste generating factors using the Relative Importance Index (R.I.I). The survey was performed among the specialists and stakeholders of Bangladesh's building industry and noted the suggestive measures of waste management. The factor identification revealed that ‘deposited material in public place’ is the most significant waste generating factor in the construction site. In addition, improper material storage, lack of training of workers, solid waste, and absence of proper guidelines for worker are also identified as the top reasons of construction waste. Following that, these issues are addressed in depth, with mitigating measures scrutinized from both academic and practical perspectives.
