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...

Modelling 3D underground legal spaces in 3D Land Administration Systems

Two dimensional (2D) Land Administration Systems (LASs) do not adequately represent 3D underground objects. It is not easy to identify the owners of these objects and the relations between objects below and above the surface are not explicitly provided. A 3D LAS can however facilitate a better understanding, as well as a more efficient...

Linking LADM with BIM/IFC standards for mobile-based 3D Crowdsourced Cadastral Surveys

The ongoing urbanization has led to the emergence of several complex constructions and multi-dimensional property rights. Traditional cadastral procedures cannot meet the demands of this new reality, leading to increased costs and long delays. Exploiting the capabilities of the latest technologies, mobile services (m-services), Building...

Easement spatialization with two cases based on BIM

An Easement is a kind of usufructuary right, and its main purpose is that one party wants to use the property of others to improve the benefits and interests of his own real estate. With increasing population and accelerating urbanization, the limitation of urban space has gradually become prominent problem. To use the spatial resources fully,...

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...

Semantically Rich 3D Building and Cadastral Models for Valuation

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces)....

Experiencing BIM Collaboration in Education

In a context of a slow uptake of the Building Information Modeling (BIM) methodology in the Flemish region, we present the results of an educational research project, carried out over 4 semesters, in a multi-disciplinary, cross-campus collaboration. This project fosters an improved application of BIM, information management and communication, by...

Collaborative design of parametric sustainable architecture

Sustainable architecture is complex. Many aspects, differently important to many stakeholders, are to be optimized. BIM should be used for this. Building Information Modelling is a collaborative process where all stakeholders integrate and optimize their information in a digital 3D model. Sometimes it is called Green BIM. But what exactly is...
