BIM Perspectives in Real Estate Operations

The chapter begins with a critical discussion of BIM in real estate (RE) operations. The number of product announcements, events and publications in the field of BIM far outweighs the number of implemented projects. The chapter shows what current and past research offers to remove existing obstacles to the use of BIM in RE operations. Based on an overview of most important initiatives in the field of standardization, the chapter first introduces research activities for digitally capturing existing buildings. Approaches to (partially) automated processing of 3D point clouds from 3D laser scans or photogrammetric surveys for the creation of BIM models of existing buildings are presented (Scan2BIM). Another research area concerns the management of BIM models during the operational phase. Innovative approaches to Common Data Environments (CDE) for RE operations based on virtual linked data integration are explained as well as the development of open platforms for the selection and support of continuous, digital tool chains for BIM processes. In the field of visualization and virtual, augmented or mixed reality, first practical implementations are presented based on selected research initiatives. BIM opens up new opportunities for using the facility manager’s know-how more easily within the planning phase. The section highlights research initiatives to develop assistance systems up to a framework for BIM-based knowledge management systems. It is also important to efficiently convey knowledge from RE operations and facility management (FM) to practitioners, trainees and students. For this purpose, new possibilities are presented using 3D gaming environments in so-called serious games. Finally, the chapter addresses research focussing on sustainability, energy efficiency and CO2 optimization. Approaches to the use of BIM for the simplified creation of ecological balance sheets with IFC-based building models are presented as well as the development of an open platform for the calculation and optimization of the CO2 footprint of facility services in RE operations. Approaches to research and testing of future scenarios for smart buildings finalize the chapter.
