Approximately 40 per cent of waste component in the world is generated from the construction and demolition of structures. Guidelines on sustainable Construction Waste Management (CWM) practice have already been published by the Construction Industry Development Board (CIDB). However, the waste amount generated is still high. Consequently, in order to identify the factors that affect SCWM efforts at site, 95 questionnaires were sent to construction players and 30 responses were received. The respondents admitted that awareness in managing construction waste sustainably among them is low and the results suggested that the degree of training and education should be increased in order to emphasize the importance and benefit of SCWM practice at site. In addition, the respondents agree that a lack of law enforcement from the Government led to the contractor not following the standard. © 2013 WIT Press.
