The Implementation of Sustainability Practices in Construction Site and its Effectiveness in Klang Valley

Awareness of sustainable and green practices in Malaysia's construction industry remains suboptimal. One key factor influencing the implementation of these practices is the level of awareness among contractors, despite government incentives aimed at mitigating the social, environmental, and economic impacts without hindering industry growth. Aligning construction growth with sustainable practices is crucial to safeguarding the future of the next generation. Notably, approximately 24% of Malaysia's carbon dioxide emissions originate from the construction sector, underscoring the importance of sustainable construction. This paper aims to analyse the factors affecting the implementation of sustainable practices on construction sites and assess their effectiveness. Data were collected through 368 questionnaires distributed among contractors in the Klang Valley region and analysed using the Relative Importance Index (RII) and Effectiveness Index (EI) methods with SPSS software. The study considered social, environmental, and economic factors influencing sustainable implementation. The findings indicate that all identified factors are deemed extremely important in influencing sustainable practices on construction sites. This research highlights the reasons behind contractors' reluctance to adopt sustainable practices in Klang Valley, providing insights for the government to improve strategies that encourage the adoption of sustainability in construction.
