Comparing Three Types of BIM-based Models for Managing 3D Ownership Interests in Multi-level Buildings

There are various 3D spatial data models to support digital management of legal and physical aspects of buildings. These data models adopt three possible approaches to represent and manage spatial dimension of 3D ownership interests, namely pure legal, pure physical and integrated methods. Building Information Modelling (BIM) is a method for...

Connecting LADM and IFC Standards – Pathways towards an Integrated Legal-Physical Model

In 3D digital land and property registration systems, simultaneous representation of both legal spaces and physical elements can aid understanding of the spatial extent of property rights, restrictions and responsibilities (RRR). The integration of legal and physical objects can be done only at visualisation level without defining any semantic...

An LADM-based Approach for Developing and Implementing a National 3D Cadastre – A Case Study of Malaysia

With the growing dominance of multi-storey buildings and other infrastructures, 2D-based cadastral systems are facing new challenges in recording, managing and visualising the spatial extent of vertically stratified cadastral spaces. In Malaysia, surveying and cadastral measurements are currently stored in the National Digital Cadastral Data...

A BIM-Driven Approach to Managing Common Properties within Multi-Owned Developments

There has been a significant growth of multi-owned developments in cities around the world. These developments include a combination of different types of residential and commercial uses of urban spaces. Common property areas in multi-owned developments typically include a wide range of shared spaces and facilities. Clear and correct delineation...

Design and Implementation of a 3D National Digital Cadastral Database based on Land Administration Domain Model: Lessons Learned from a 3D Cadaster Project in Malaysia

With the growing dominance of urban infrastructures in Malaysia, 2D-based cadastral systems in this country are facing new challenges in recording, managing and visualizing the spatial extent of urban land parcels. In Malaysia, surveying and cadastral measurements are currently stored in the National Digital Cadastral Data Base (NDCDB), which is...

3D Cadastre in Australian and New Zealand Jurisdictions: Similarities and Differences

Many research studies have been recently conducted in Australia and New Zealand to explore a range of technical, legal, and institutional aspects related to modernisation of 3D cadastre. Most of these studies focus on a particular jurisdiction. This stems from the fact that each jurisdiction is responsible for their own cadastral system....

Development of an LADM-based conceptual data model for 3D underground land administration in Victoria

Currently, many cities around the world use underground space for different applications such as tunnels, utility networks, parking, walkways, and shopping malls. Due to the increasing use of underground areas, management of this space is very important for decision-makers and stakeholders. A 3D Underground Land Administration (ULA) data model...

Evaluation of the International 3D Geospatial Data Models and IFC Standard for Implementing an LADM-based 3D Digital Cadastre

Land Administration Domain Model (LADM) is an international standard for defining both semantic and spatial information connected with rights, restrictions, and responsibilities (RRRs) that affect land, water, built assets, natural resources, underground spaces, and airspaces. Since LADM is currently a conceptual land administration model, one...
