Global efforts are being made to introduce Building Information Modelling/Management (BIM) that links various types of information, such as time and resources, to 3D models. In Japan, from 2023, the Ministry of Land, Infrastructure, Transport, and Tourism has made it mandatory to submit 3D models as reference materials for construction works above a certain size. To improve productivity, 3D models can be introduced in the planning, survey, and design stages. Subsequently, in each of the subsequent construction and maintenance stages, they can be linked and developed so that information can be shared among the stakeholders and plans can be reconsidered at an early stage. For this purpose, the ISO 19650 international standard has been established because information management among the stakeholders is crucial. However, only few Japanese construction companies have ISO 19650 certifications. In Japan, i-Construction initiatives are being implemented to achieve the BIM objectives. However, unlike in the UK and Singapore, where BIM applications are more developed than those in Japan, information management is lacking. Therefore, a questionnaire survey was conducted to assess the use of BIM in construction projects, engineering education, and productivity improvement activities in Japan. Accordingly, how BIM was used by Japanese construction companies in the field was analyzed and discussed. The results of the questionnaire confirmed that the level of BIM commitment at the design stage was relatively low. Some constructors were highly committed, while many were not. Consequently, we managed to grasp the efforts made towards the recognition and adoption of ISO 19650 standard.
