Factors affecting the implementation of BIM (Building Information Modeling) in Off-site Construction at construction companies in Ho Chi Minh city

Abstract

Building Information Modeling (BIM) and Off-site Construction (OSC) are recognized as potential solutions to longstanding issues such as low efficiency and productivity in the construction industry, and are set to transform the sector profoundly. This study aims to identify and evaluate the factors that influence the implementation of BIM in OSC projects in Ho Chi Minh City. To conduct the research, data was collected from previous studies, resulting in the identification of 27 factors related to BIM implementation. A survey questionnaire was developed and used to gather opinions from experts, contractors, and construction companies. After data collection, 172 valid responses were analyzed. The findings of the study reveal that 5 key factors have a significant impact on BIM implementation in OSC in Ho Chi Minh City, including financial factors, legal standards, human resources, and technology. Based on these findings, the study offers several important recommendations, including improving financial policies to support BIM adoption, developing and refining national BIM standards, and enhancing human resource training to increase the capacity for BIM use in OSC projects in the future. These recommendations aim to optimize BIM implementation and contribute to the sustainable development of the construction industry in Vietnam.
