Abstract
Construction industry is one of the wide, decentralized and highly aboriginal industries in any country, therefore this industry considered as an indicator for growth and development or economic recession in many countries. This industry is currently suffering from many inefficiencies. One of the main reasons for this problem is the lack of growth in the technical field. The use of traditional methods is known as one of the main factors inhibiting productivity in the construction industry in Iran, because most of the traditional methods and their nature led to time delay and waste of resources. In addition, on account of increasing complexity of projects, there is a fundamental need to use more integrated, compatible and cost-effective approaches and technologies for the entire project life cycle. Today, one of the most thriving and flourishing technologies in AEC industry is Building Information Modeling (BIM). Despite the many advantages mentioned about the new BIM system, there are also some challenges and problems associated with it, which in some cases they can be very serious and bring great risks. In this research, with the intension of emphasizing and recognizing the barriers to BIM implementation, some challenges and obstacles of using this technique have been investigated. In order to identifying the barriers, questionnaires and interviews were used, and then the barriers were identified and ranked using the fuzzy Delphi technique. Among the sub-criteria, the lack of instructions for the use of BIM in related organizations, which is a sub-criterion of managerial and procedural barriers, ranked first.
