Investigation of BIM Implementation Barriers in Iranian Construction Industry

Building Information Modeling (BIM) is a revolutionary technology and process that has quickly become a way of understanding, designing, constructing and commissioning buildings. BIM is a rich set of smartly designed information that the right data can be extracted and analyzed according to the needs of users to be used to decide and improve the building information process. Building Information Modeling BIM is a simulated multi-dimensional model of building geometry, spatial relationships, geographic information, quantities and properties of all building components and their interconnectedness. The use of BIM in project planning and its early stages allows the project team to analyze relevant environments and understand the complexities of the environment and to understand relevant laws and regulations in an effective way. Reduced time and costs for the project are capable of effectively implementing value engineering for the project and can also reduce project overlaps and inconsistencies. In this regard, this study aims to examine the barriers and challenges ahead in implementing the Building Information Modeling (BIM) approach. Therefore, by identifying these barriers and distributing a questionnaire among the statistical population, which consisted of 200 employer managers, construction consultants and contractors in Tehran province and other cities, each of them was prioritized by using a hierarchical analysis method. Overall, several major categories of personal barriers, organizational barriers, technical barriers, financial barriers, and cultural barriers are the identified important factors of this study. In general, the results indicate that most construction industry stakeholder such as employers, contractors, and consultants are not familiar with the benefits of construction building information modeling and the top facilitator as results are: Government pressure, Support from top management, Rising the BIM understanding, Request by clients, the Training program for BIM.
