| Summary: | In Malaysia, the huge generation of construction waste (CW) has led to negative
impact on the environment. Limited data is available on quantification methods of CW
in the country. The lack of quantification methods has resulted to the improper
management of CW. The consequence of the improper CW management has shortened
the lifespan of landfills. The aim of this study is to compare the construction waste
generation rate between different construction methods. In order to obtain CW data in
terms of volume and weight, the site visit (SV) method was carried out for a 3-month
period. There are two types of SV methods applied in this study, namely direct
measurement and indirect measurement. The data were collected from 12 social
amenities projects at the construction stage which can be divided into the Conventional
Construction Method (CCM), the Mixed Construction Method (MCM) and the
Industrialised Building System (IBS). The waste (tonnes) obtained from each
construction method is divided by gross floor area (m2) to attain the Waste Generation
Rate (WGR). Finally, the result of the study revealed that the WGRs for IBS, MCM
and CCM are 0.018 tonne/m2, 0.030 tonne/m2 and 0.046 tonne/m2 respectively. It can
be concluded that the IBS method is the most effective method to reduce CW
generation on site. This finding will be a contribution for construction players, policy
makers and authorities in the country to promote IBS methods more rigorously. |
