Challenges in the Execution of Industrial Building System (IBS) Project in Private Sector

The adoption of the Industrialised Building System (IBS) has been widely promoted in Malaysia to enhance construction efficiency, quality, and sustainability. However, despite its recognised benefits, IBS implementation in the private sector continues to face significant challenges. This study aims to identify and rank the key challenges affecting the successful execution of IBS projects in Malaysia's private construction sector from the perspectives of construction professionals. A quantitative research approach was employed, involving the distribution of structured questionnaires to professionals, including engineers, architects, quantity surveyors, site supervisors, and project managers. A total of 100 valid responses were received and considered valid for analysis, representing a response rate of 50%. The findings revealed that cost implications, a lack of skilled labour, and resistance to change were the top three challenges hindering effective IBS adoption in private sector projects. The study points out the need for enhanced stakeholder awareness, better training initiatives, and financial incentives to support the growth of IBS. These insights are valuable for policymakers, contractors, and developers aiming to improve the efficiency and acceptance of IBS in Malaysia’s private construction landscape.
