Industrialized Building System (IBS) is a construction system in which components are factory-made in a measured atmosphere (on or off-site), placed, conveyed, and collected on site with minimal additional site activities, according to the Construction Industry Development Board Malaysia (CIDB). The application of IBS in construction projects could significantly improve site performance in terms of protection, quality, charge efficiency, production, sustainability and waste reduction. In the construction industry, sustainability has become increasingly essential. Meanwhile, due to the extremely difficult constraints that stakeholders encounter in adopting new technology and a scarcity of experienced labour, the degree of IBS implementation in Malaysia remains low. According to several studies, typical IBS is gradually being pushed to the background. However, no systematic study applying bibliometric examination of IBS studies to more investigate relevant study in this field was uncovered. This study offers an outline of the IBS current studies gathered from "Web of Science"database. To visualise the material included in the study scope, VOSviewer was combined with bibliometric analytic techniques. As a conclusion, six clusters were discovered that focused on these primary theme segments: IBS approach, prefabrication, construction, innovation, sustainability, and management. Based on the current gap, this paper makes recommendations for future IBS research. Assisting the IBS research community with research and development. © 2022 IEEE.
