Abstract
There has been significant research on the intersection of 3D cadastre and building information modelling (BIM) over the recent years. BIM provides a multidimensional environment for capturing, curating and communicating the physical and functional aspects during a building’s lifecycle. A BIM-based solution for 3D cadastre provides a rich repository of legal and physical datasets in a common environment. The knowledge encapsulated inside a cadastral BIM model should be tapped to unlock the value of 3D cadastral information. Therefore, this article aims to develop BIM-based queries for interrogating questions about the legal ownership of properties inside multistorey buildings. These queries include identifying legal spaces that belong to a private or common property; querying physical elements that bound a legal space; and finding legal spaces that are adjacent to each other at a specific building element.
Highlights
The prolific increase in 3D models describing the physical reality of our world provides a good opportunity for cadastral systems to shift from 2D to 3D information environments [1,2,3]
We used a modified version of Query 2 to query all legal spaces in the Building information modelling (BIM) model, which is illustrated in illustrated in
Effective management of 3D cadastral information in a BIM environment is predicated on good data query mechanisms to deliver untapped knowledge about ownership arrangements and legal boundaries in spatially complex situations
Summary
The prolific increase in 3D models describing the physical reality of our world provides a good opportunity for cadastral systems to shift from 2D to 3D information environments [1,2,3]. Previous research shows that 3D-enabled cadastral systems would provide an efficient mechanism to disseminate cadastral information related to complex situations, addressing the legal and physical intricacies in urban built environments [4,5,6,7,8,9,10]. The BIM environment is being adopted for managing the lifecycle of infrastructure facilities such as tunnels, bridges and roads. There are new extensions of the IFC standard for modelling infrastructure objects [21]
