Abstract

Construction waste management is defined as a tool for controlling disposal costs of construction wastes, as well as facilitating examination of other alternative disposal methods such as recycling and reusing in order to reduce wastes that are finally disposed to landfills. This study is aims to identify the factors causing construction waste generation, type of construction waste management, major benefits of waste management as well as difficulties faced by Malaysian contractor when implementing construction waste management. At first, there are 18 causes of construction waste is analyzed by independent sample t-test and no significant differences between Grade 6 and Grade 7. Next, the second objective as construction waste management plan is analyzed by Chi-square test of independence and independent sample t-test. Chi-square test is introduced to analyze the relationship between contractors‟ grade and the need of waste management procedure. Moreover, it also tested the relationship between contractor‟s grade and whether the construction waste reduced by CWMPs implemented. However, there are no relationships between Grade 6 and Grade 7 in this two categorized variables. The implementation of 6 types of waste management plans is then analyzed by independent sample t-test. The results shows that half of the variables are tested as significant differences, whereas the remaining half is tested as no significant differences among the contractors‟ grade. The third objective is consists of 12 benefits in implementing waste management in aspects of economic, environment and social. Also, the independent sample t-test is investigated that all of the benefits in implementing construction waste management is not depends on the contractors‟ grade. The last objective in this study is to examine the difficulties faced by Malaysian contractor in implementing construction waste management. There are 12 difficulties is faced by main contractor that categorized into social culture, legal, financial and technical. Same as the previous objectives, it also using an independent sample t-test and the results shows that all of the difficulties are no significant differences between Grade 6 and Grade 7 in additional to a significant difference exists in the technical matters. Lastly, for the independent sample t-test is finding that no more differences between the main contractors from Grade 6 and Grade 7 in regarding to causes of construction waste and major benefits of waste management in the construction industry. However, there may have slightly difference for the types of waste management plan that implemented as well as difficulties of waste management plan in aspect of technical factors. Moreover, Chi square test of independence is also mentioned that no more relationship in regarding to the performing of construction waste management plans in the chapter of findings.
