The benefits of BIM are well known in construction industry. Yet, the use of BIM is not as widely spread as the benefits could entail. Finland has been active in the deployment of BIM during the past few years and recognized in many studies as one of the leading countries. Hence, I feel that it is necessary to take a closer look at the levels of BIM implementation and to identify, study and understand the possible barriers that prevent us from reaching the known benefits. In addition to a thorough review of the literature available, I wanted to approach the topic in the field. With the help of focus group sessions, it was possible to first, observe each benefit of BIM and then identify the real-life barriers preventing a successful BIM implementation. The focus groups were formed with around 80 Finnish BIM specialists coming from design, construction, maintenance, research and public organizations.
