This review paper present the challenges faced by the construction industry to integrate the prefabrication construction with the existing traditional method and to make the comparative study among the three countries; United Kingdom, Australia and Malaysia. Malaysia applied industrialised building system (IBS) which is defined as a construction system where components are manufactured at factories on or off- site, transported, and then assembled into a structure with minimum work. IBS involves prefabrication and installation of components at the construction site. While, modern method of construction (MMC) is the term used by the United Kingdom government to describe a number of innovations in house building. However, offsite manufacturing (OSM) is the term used for Australian and UK construction industries. This research studies the pattern of MMC, OSM and IBS to identify the pattern research scholars in the three countries and precast concrete system become popular system. Conversely, to highlight the important role of the government and researcher in educating the construction industry players and to transform the construction industry into a modern and efficient industry Keywords: Industrialized Building System (IBS), Modern Method of Construction (MMC), Off-site Manufacturing (OSM), IBS components, pattern of off-site ISSN 2232-1309 © 2012 Royal Institution of Surveyors Malaysia 1.0 INTRODUCTION The building sector has yet to undergo a complete phase of industrialization. Yet, if a car was produced the way a building is delivered, very few people would be able to own one; if a computer was produced the way a building is delivered, it would cost a fortune (Richard, 2005). This demand can be met by means of the advanced technology used in the Industrialized Building System (IBS) or prefabrication system. Malaysia possesses the “hardware elements” of the industrialized building systems technology with only a little concern on the structure, but still lacks the “software elements” regarding availability of data and information on the system, users, clients, manufacturers and assembly layout and process, as well as allocation or resources and material (Badir et al., 2002). Most of the construction industries have the resources but still lack on the constructability concepts and the advanced technology that can enhance the speed of construction, improve the quality of the structure and be able to protect the environment. However, the concept of constructability started in the late 1960s to integrate the optimum use of construction knowledge and experience in the conceptual planning, detail engineering, procurement, and conduct field operations in phases to achieve the overall
