Part 4: Building Information Modeling (BIM)International audienceBuilding Information Modelling (BIM), as an object-oriented tool, has been the buzzword in Architecture Engineering and Construction (AEC) sector in recent years. The buzz has created a lot of promise of an imminent paradigm shift and productivity and lifecycle improvements in the AEC sector, and plenty of benefits are cited in the literature. Consequently, the word has reached the shipbuilding industry as well, which faces many similar productivity and lifecycle challenges as the AEC industry, and which is seeking similar advancements in digital tools that can bring around the change. As a result, the Finnish shipbuilding industry expressed interest in exploring what are the BIM-enabled best practices in the AEC sector, and which of these can potentially be transferred to the shipbuilding industry. This research explored these issues. Findings suggest that due to lack of mutual communication, the professionals across each industry believe the other to be doing better
