Risk Factors Influencing BIM Accuracy and Efficiency in Construction Projects

Various challenges face Building Information Modeling (BIM) application in construction projects. The primary goal of this research is to identify the key challenges in the form of risks that considerably impact BIM application in the construction industry. Also, this research aims to analyze and evaluate the impact of these risks on the accuracy and efficiency of BIM application. A multi-stage field survey approach was employed and two innovative risk factor indices, namely the Risk Factor Indices for both BIM Accuracy and Efficiency, were utilized to assess and rank the severity of the verified risk factors. Fifty-six risk factors that had an impact on BIM accuracy and efficiency were presented and divided into four groups, including technology issues, managerial issues, financial matters, and legal regulations. Based on a thorough discussion and analysis, it was determined that managerial issues represent the highest risk category, while the lowest risky group was linked to legal regulations. The results indicated that the "Inadequate project management and top managers experience" risk factor had the highest probability of occurrence, and also had the highest influence on BIM efficiency. On the other hand, the risk factor of "Lack of available skilled personnel, or replacement of experienced employees" risk factor had the highest influence on BIM accuracy. The planning process had the highest enhancement through implementing BIM. This study introduces a strategy for improving the comprehension of the risks that restrain BIM and sets the groundwork for future research and advancements in BIM application in constructions.
