Building information modelling for 3D underground land administration: Research challenges and future pathways

Le résumé fourni par la source

Underground land and property information is currently recorded, registered, and managed using two-dimensional (2D) datasets provided in survey plans. There are significant communication challenges associated with fragmented 2D land and property data in complex underground projects. On the other hand, building information modelling (BIM) has been adopted for three-dimensional (3D) digital management of the lifecycle of built assets, including those of underground infrastructure. BIM can potentially provide a fully integrated 3D representation of rights, restrictions, and responsibilities for underground assets. Therefore, this study investigates the potential of BIM to support the development of 3D underground land administration (ULA) through an integrated data modelling approach. By reviewing the current body of knowledge, research challenges, and future pathways for adopting BIM-based approaches for 3D ULA data management are identified, specifically across legal, institutional, and technical dimensions. One key finding is the critical transition from current 2D approaches to BIM environments. This will lead to integrated and smooth information flow, which is critically important for more efficient ULA practices, enhancing communication among various stakeholders, improving decision-making in ULA, and contributing to sustainable underground space planning and development.
