Based on previous studies, prefabricated building usage motivations in the construction sector differ over time and vary from country to country. To adopt this technology, awareness on current trends and the latest innovations should be increased by reviewing previous studies. The objective of this study is to conduct a revision of common motivations and limitations of prefabricated building in the construction industry taking into consideration the experience gained and reported by several countries. Results show that the adaptation of prefabricated building mainly depends on factors such as labor shortage, labor cost, housing demand, building process efficiency, weather, as well as reduction of waste material and energy consumption. Prefabricated building has a relatively low uptake in construction industries worldwide despite its inherent economic, environmental, and social benefits.

The drive toward implementing an industrialized building system (IBS) in Malaysia is in line with Malaysia's Construction Industry Transformation Plan 2016-2020, which seeks to increase more than double the construction industry's productivity. IBS is able to accelerate the construction timeline, provide a safer working environment on site, produce a higher quality of construction, and save costs. Although the introduction of IBS in Malaysia is not new, its acceptance has not been extensive, and IBS implementation is still slow. Thus, to support the successful implementation of IBS, it is vital to determine the factors that influence the achievement of this aspiration. Therefore, this study aims to identify and evaluate the critical success factors (CSFs) that contribute to the smooth implementation of the IBS dimensions within the context of the Malaysian construction industry. By doing so, the uptake of IBS can be accelerated. In order to consolidate the set of candidate success factors, these CSFs were identified from the literature review and confirmed through a self-administered survey questionnaire. Then, the value of importance of each CSF was calculated in a second survey. Based on the factor analysis, 15 CSFs were identified and grouped into five major elements: strategy, sources of funding, process, people, and enabler, with each factor comprising its own set of components. The findings indicate that the CSFs in IBS implementation have different priorities and weights.
