In recent years, due to the rapid growth of the urban population, land scarcity and high costs particularly in metropolitan áreas and limitations in horizontal city expansion, vertical development and high-rise construction have significantly increased. Despite the numerous advantages of the vertical urban expansion, several criticisms exist, including a lack of transparency in ownership boundaries and spaces, ambiguities regarding rights, restrictions, and responsibilities associated with these spaces, which lead to conflicts of interest among owners and generate various legal and social issues. In response to this challenge, 3D cadastre has been introduced as an effective tool to address the mentioned issues. Building Information Modeling (BIM), which has recently brought significant advancements to the construction industry, has become a focal point for the researchers working on 3D cadastre. The existing BIM-based methods for 3D cadastre have been highly successful in registering and visualizing the 3D ownership boundaries and spaces. However, their dependency on the local jurisdictional frameworks and lack of support for temporal aspects of cadastre are among the challenges in operationalizing these methods. This paper introduces a method based on the extension of the Industry Foundation Classes (IFC) (ISO 16739: International Organization for Standardization, Open Standard No. 16739) for managing 4D property rights in multi-story buildings, in accordance with Iran’s apartment cadastre regulations. The proposed approach details how to manage the temporal aspects required for 4D cadastre, along with registering land parcels and the adjacent plot information, modeling and registering the subdivided units on each floor, and defining and recording the boundaries of private, shared, and servitude ownership spaces. To evaluate and demonstrate the effectiveness of the proposed method, the division of the apartments of a 12 storey building in Iran was implemented and visualized. The results of this study indicate that the proposed method and the newly introduced IFC classes are well-suited for managing, registering, and retrieving the spatial 3D and temporal aspects of ownership for the urban land management applications. |
