The introduction of BIM7D technology in the procedures of designing, investing in, managing and maintaining of facilities is a logical continuation of the development of previous information technologies for project and environmental management and related processes. It is intended for the comprehensive management of projects in various phases with the purpose of reducing costs in each phase of the life cycle of the facility. The BIM7D technology is connected with the existing information systems and digitalisation processes that the company uses for maintenance and management processes. It is necessary to introduce BIM7D for new projects due to the recommendations of the European Union related to public procurement, while it is suitable to raise the management and maintenance of the existing facilities to the BIM7D level. In doing so, we will introduce innovative 3D virtualisation of energy facilities such as: engine room, the bed of the Drava River and similar.
