| Summary: | The escalating issue of construction material waste in the global construction industry has
raised concerns among stakeholders. Addressing this challenge has become particularly
difficult for contractors engaged in construction projects at the worksite. In Malaysia, the
inadequate waste management practices of construction stakeholders, as evidenced by poor
waste record-keeping, insufficient waste sorting and recycling measures, and inadequate
support from clients and authorities, underscore the need for enhanced waste management
awareness. Consequently, this research aims to explore the causes of construction material
waste in the Kuching residential construction and its waste management initiatives. Three
research objectives were formulated to address the corresponding research questions. The
quantitative approach was employed in this study, employing a structured questionnaire
survey with a five-point Likert scale to generate data for analysis. The target respondents
were CIDB-registered contractors ranging from Grade 6 to Grade 7 involved in residential
projects. The questionnaire consisted of seventeen variables related to the causes of
construction material waste and six waste management initiatives identified through an
extensive literature review. Data collected from the respondents were analyzed using the
SPSS. Furthermore, the stakeholders' willingness to pay (WTP) for construction waste
management was evaluated using the contingent valuation method (CVM). Through factor
analysis, the identified factors were categorized into four groupings: Material Procurement
and Handling-Related Causes, External Influences-Related Causes, Operational Efficiency
and Collaboration-Related Causes, and Design and On-Site Efficiency-Related Causes.
Among the six waste management initiatives, waste reduction planning activities ranked
highest. Additionally, the analysis revealed no statistically significant difference in reported
willingness to pay (WTP) between the two contractor groups, as indicated by a p-value
exceeding 0.05. The findings of this study offer valuable insights and serve as a reference for
professionals in the construction industry |
