The roles of contractor in implementing industrialised building system in Malaysia

In line with the Government's Industrial Revolution (IR) 4.0 policies, Malaysia's rapid development is something to be proud of. However, the low implementation level of the Industrialized Building System (IBS) construction method is a main cause of concern for construction stakeholders due to negative perception toward this method. According to the literature, many contractors choose to use the traditional approach rather than the IBS method in their construction projects. As a result, the goals of this research are to identify the roles of contractors in the implementation of IBS construction, to identify the challenges that contractors faced in implementing IBS construction, and to recommend improvements on the IBS construction implementation. The data for this study were gathered using a questionnaire survey distributed to the target group of CIDB-registered grade 7 IBS contractors. A total of 200 questionnaires were distributed, with 90 being returned. The descriptive analysis method was used to analyse the data collected using SPSS software. The study concludes that despite the contractor's role and the barriers they encounters are not critical, most of strategies to enhance IBS construction usage are critical. Contractors' primary function in IBS construction is to train employees to improve their IBS construction abilities, whereas an oversupply of untrained labour in the IBS construction business is a major impediment to contractors implementing IBS construction methods.
