Previous surveys reported that waste management has been receiving less attention from business senior management in comparison with construction cost and time. Nowadays, construction waste is considered one of the factors that lead to the problems faced by man and animals which ultimately results in economic, environmental and biological losses. Thus, waste minimization is an important area of concern in the implementation of construction waste management in the construction industry of Malaysia. The studied shows that enforcement of the Industrial Building System (IBS) method by the government can reduce construction waste by as much as 41-50 percent, which is a big amount of reduction (Bukhari, 2009). The comparative level of waste generated at site when using the IBS method
and the conventional method also shows that IBS has a lower mean level of waste generated than the conventional method. This shows that our government is serious about reducing the waste management at site and IBS is one of the factors that contribute to less generation of waste at site. The result of this study also shows that most of the factors that contribute to the generation of waste come from the traditional construction method used by most contractors.
