A BIM-based approach to design a lifecycle 3D property formation process: A Swedish case study

3D property formation has become an important solution to provide a more comprehensive and accurate rep-resentation of the property's physical characteristics than traditional 2D property formation. Despite the numerous benefits of the 3D property formation, there is a need for more detailed descriptions of 3D cadastral data delivery between the involved actors to ensure efficient and effective collaboration. In particular, the practical difficulties are when/what related 3D cadastral information and models should be exchanged and stored from/to whom. Therefore, to address these issues, we propose a lifecycle 3D property formation process with four phases by designing an IDM process, which is an international open BIM process standard. In the purpose of forming a Swedish lifecycle 3D property formation process, the IDM process has been applied through organizational, legal and technical aspects, including identifying actors and their roles and values, gathering 3D property formation requirements, defining the data exchange requirements and designing the process map. Moreover, a case study was used to specify the Swedish lifecycle 3D property formation process and information delivery between stakeholders in the IDM. The aim is 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 process is quite generic and could also be applied in other countries.
