COST-BENEFIT ANALYSIS OF USING BIM COMPARED TO TRADITIONAL METHODS IN IRAQ'S PUBLIC CONSTRUCTION PROJECTS

The construction procurement process generates significant cost-related issues, such as project delivery delays, budget overruns, and poor quality. Public projects were suffering from bureaucracy and separation in work activities. Building Information Modeling (BIM) has demonstrated the potential for solving these issues. The study aims to investigate and analyze the cost-benefit analysis of using BIM compared to traditional methods in public construction projects in Iraq. Therefore, the study evaluated Multiple case studies of two projects quantitatively and conducted several interviews with 15 experts to determine the cost-benefit of adopting BIM compared to conventional methods. The study investigated the benefits of BIM in construction projects due to the remarkable difference between the two methods. The quantitative data of study findings revealed a significant cost improvement using BIM rather than the traditional method in public projects. To conclude, multi-cultural studies need to assess the projects' performance of large and small entities. Furthermore, this research suggested incorporating BIM adoption in government organizations in a wide range.
