A BIM-based approach to design and development 3D property formation process_a Swedish case study

• During the past decade, 3D property formation has shown increased interest and significance with high demand for 3D cadastre. The 3D property formation process should facilitate solutions to complicated problems within building projects (for example space above and below the ground) and provide secure and lasting rights in complex situations. In addition, the process should clarify clearly how the involved actors exchange and share information between each other. It is important to provide efficient, clear and unambiguous methods to form 3D property units, as well as to register 3D property RRRs (rights, restrictions and responsibilities).In this paper, to achieve sustainable property management, a lifecycle process for 3D property formation is proposed with four phases: initiation, preparation, decision and registration phase. In order to model cadastral information and model exchange, we utilize the Information Delivery Manual (IDM, an open BIM process standard) for clarifying the detailed property formation process, facilitating actors’ communication and harmonizing 3D cadastral data models delivered, to improve the cadastral management more efficiently and collaboratively. In the IDM process map, the main actors are identified to illustrate responsibilities and activities to delivery of cadastral information and models. Moreover, the four phases of the lifecycle 3D property formation process are explained, and the detailed data/model exchange flow among different actors is described. A case study is developed to specify the Swedish 3D property formation process and information delivery between stakeholders in the IDM. The proposed methodology aims to facilitate a standardized and unambiguous digital 3D property formation procedure on a national level in order to improve and enhance the digital Swedish Cadastral and Land Administration Systems, but the methodology is quite generic and could be applied in other countries.
