DfMA for a Better Industrialised Building System

To improve the performance of the construction industry, innovative methods were introduced to make them better. Industrialised building systems (IBS) and prefabrication construction are the popular methods used and studied. However, these methods are still unable to meet the demands of the stakeholders. Design for manufacturing and assembly (DfMA) is a design principle that is seen as capable of improving the situation. The uptake of DfMA in the construction industry needs to be analysed to obtain a better picture of the existing condition of the method and its manner of implementation it going forward, but there are still too few studies performed on this topic. This paper gathers relevant articles from the previous studies on DfMA. With the available data, the main benefits, hindrance factors, and enabling factors for DfMA uptake in the construction industry were identified in this study. The authors also identified the research trend among the research themes and the benefits of building information modelling (BIM) integration with DfMA. By synthesising the information from previous studies, a conceptual framework was developed. Knowledge gaps and future potential research topics are also discussed in this paper, forming a simple research framework for future effort guidance. With a suitable strategy and guidelines, the application of DfMA could improve the performance of the construction industry in Malaysia and other places with similar construction environments and approaches.
