Building Information Modelling Execution In Administrative And Commercial Spaces In Iran - A Fuzzy-Delphi Criteria Prioritization

Building information modelling (BIM) is considered an innovative approach which is under development all over the world in architecture, engineering, and construction fields. Iran, among the developing countries, has the potential to adapt itself to achieve sustainable development, especially in building construction industry. Thus, this country is selected as the target of this research. In developing countries such as Iran, the construction industry is currently on progress, but in our best knowledge, there is no evidence for the effective and commercialized execution of BIM yet. The final aim of BIM application would be to make public and private projects more sustainable. Hence, in order to push this technology forward and provide more sustainable conditions for developing countries, such as Iran, this study emphasizes the main challenges and obstacles in the utilization of BIM in the construction industry. A Fuzzy-Delphi questionnaire was designed in order to acquire consensus among the scientific community about the criteria that may affect the implementation of BIM in constructions. The questionnaire was then analyzed by using SPSS (25.0). Results clearly demonstrated that the time required for BIM designing step, along with associated costs and lack of motivation among the involved parties are the main obstacles preventing the commercialized implementation of BIM in the construction projects.
