Abstract. Nowadays development of construction in Malaysia has been effect to the increasing of construction waste. Additionally, the production of construction waste from construction projects has given negative impact to the environment especially in illegal dumping activities. The increasing number of illegal dumping activities from construction projects in Malaysia gives a sign that Malaysian construction waste management needs to be concerned. To date, a comprehensive criterion for construction waste management, particularly for a construction project in developing countries is still not clearly defined. Therefore, construction waste management in Malaysia needs further research. The objectives of this paper are to explore illegal dumping activities, and discuss the contributory factors of illegal dumping activities. Hence, this research conducted an interview with expertise in the area of construction waste management in order to scrutinise illegal dumping activities in Malaysia. The data from semistructured interviews were analysed by content analysis. Findings from this research will help to find out the strategies to reduce the illegal dumping activities. The final result also expected to increase the awareness and better solution for reducing illegal dumping activities in construction projects among construction players.

Utilization of Industrialized Building System (IBS) becomes increasingly dominant in the construction of affordable housing in Malaysia. Theoretically, utilization of IBS system can benefit to reduce the affordable housing price due to the less labor involvement and short constructions time. However, current IBS usage in housing construction still cannot fulfill the affordable housing demand especially in term of price and housing quality. Recent study reveals the lack adoption of IBS component in construction industry mainly caused by poor perception among stakeholder toward the system. Hence, some alterations in the supply of the IBS component essential to being prepared in order to reach the price target to permit all middle-income groups to own the quality house. Construction industry also can explore the other types of IBS system focusing on lightweight types such as wood or steel system which clearly could give benefit to the housing industry on faster works and high housing quality. Due to strong and durable characteristic of lightweight steel panel, it can be seen as an alternative component to be explored to enhance construction practices of affordable housing project. Therefore, the main purpose of this study is to identify the potential of lightweight steel panel system to be implemented for affordable housing project. Accordingly, for the highlight in reducing affordable housing price integrate with provision of good quality housing this research focus on feedback from developer about the proposed lightweight steel panel system. This research conducted an interview with six project managers with more than three years working experience in housing construction project at South of Peninsular Malaysia. Developer’s experience in affordable housing project mainly for landed house is coinciding because of lightweight steel panel system suitability for not more than two stories house. The result reveals that, respondent prefer to the advantages of lightweight steel panel system in term of faster installation works, low maintenance work, flexibility and smart construction. In conclusion, the ability of the system to decrease housing price at the same time sustain the desired quality of housing will increase ability and satisfaction for middle-income earner to own the house.

The high demand-supply gap of affordable housing has been a major issue in Malaysia and has increased housing prices. A conventional method of construction is not reliable in delivering the increased demand for housing. Additionally, Industrialised Building System (IBS) faced difficulties to be implemented smoothly due to the issue related time, cost and quality. Therefore, light steel panel (LSP) system, is one of the IBS types; can be utilized in a housing construction project. This new system can replace the conventional method that was currently used in the construction of an affordable housing project. The objectives of this study are to identify the potential of LSP and the influencing factors of system implementation. Interviews are conducted with three project managers who have working experience in Syarikat Perumahan Negara Berhad (SPNB), Kumpulan Prasarana Rakyat Johor Sdn Bhd (KPRJ) and PIJ Property Development Sdn Bhd as a developer of affordable housing in Johor. Two contractors from G1 which have more than three years’ experiences in implementing affordable housing project in Malaysia were also interviewed. Based on the interview, it is expected to define the potential and influencing factors of the LSP system. The findings are meaningful in framing and enhancing construction housing method of an affordable housing project in Malaysia.
