Abstract

Due to the demand of development in the construction industry rises, the amount of construction waste increases rapidly and causes impact to the environment. Statistics research showed that the construction industry has contributed a huge amount of waste towards Malaysia and it is a problem that needs to be solved promptly. It is well-established that efficient construction waste management is crucial to prevent any rise of negative impact to the environment and human health. This study aims to investigate the waste management in Malaysia construction industry which include the investigation of the causes of construction waste, waste management hierarchy in the construction industry and importance of construction waste management. In this context, construction waste is defined as any substances, object, or thing that was generated due to construction work and like renovation. To test the hypothesis of importance of construction waste management in the construction industry, an online survey was distributed to grade 6 and grade 7 contractors registered under CIDB. Simple random sampling was adopted to randomly pick 100 respondents within Kuala Lumpur, Malaysia grade 6 and grade 7 contractors. Responses were analysed using normality test (Koimogorov-Smirnov’s test), kruskal-wallis test and kruskal-wallis 1-way ANOVA test as post-hoc test to test the differences of data between different groups in variable such as working experience, and education qualification. It showed that there is a major significant relationship between construction waste and design changes as the respondents chose frequent design change as remained top 5 in this study. For waste management hierarchy where 3Rs has been concluded to be the best waste management method to be done before disposal of waste to landfill. Lastly, the benefits of good construction waste management can significantly lead to cost saving and profit maximisation as shown in this study.
