Analysis of risk factors and proposal for integrating building information modeling (BIM) with risk breakdown structure (RBS) in the construction phase of high-rise building projects in Vietnam

Abstract

In the context of a rapidly growing construction industry with increasingly complex high-rise building projects, risk management has become a critical factor in ensuring project schedule, quality, and cost control. Aiming to enhance the effectiveness of risk management practices in such projects, this study seeks to identify the risks affecting the construction phase of high-rise developments and analyze their impacts. A total of 41 risk factors were identified based on a review of previous studies, combined with in-depth interviews with industry experts who have extensive experience in the construction field. A structured questionnaire was then developed and distributed to 70 respondents, resulting in 63 valid responses used for analysis. Based on the analysis, the risk factors were ranked in descending order of impact during the construction phase. These findings serve as a foundation for proposing an integrated model that combines Building Information Modeling (BIM) and the Risk Breakdown Structure (RBS), aimed at supporting effective risk identification and analysis, thereby contributing to improved performance and quality in Vietnam’s construction industry.
