Extraction of Exterior Building Envelopes from Building Information Models

With the development of technologies and people’s raising standards for both indoor and outdoor environments, buildings have expanded their functionalities of merely being human’s everyday sheltering place. Common modern building applications include but are not limited to Building Energy Modelling (BEM), solar potential estimation, wind...

How could BIM support the digital building permit process in the Netherlands?

The building permit process in the Netherlands is mostly digitalized, however, there are still some issues. A downsize of information, the manual checking from the municipality, and the duration of the process are some of these issues. To overcome these issues information between 3D building design models, so-called Building Information Modeling...

Modelling the legal spaces of 3D underground objects in a 3D LAS

Urbanisation and a lack of available construction land has led to the increased development of underground space which can contribute to the development of the urban areas by providing space for the construction of (infra)structural objects and networks necessary for a city to function and provide services to its citizens. The main challenge in...

Automatic Conversion of CityGML to IFC

This study presents a methodology to convert from the most dominant 3D city model standard in 3D GIS to BIM. Namely, CityGML to IFC. IFC is chosen because it is the common open standard to exchange data in the BIM world. For the aim of this study, the two standards are divided into 5 comparable sub-parts; Semantics, Geometry, Geographical...

Integration of 3D BIM Models in a Web GIS for Life Cycle Asset Management

In recent years, there has been a growing necessity for 3D geoinformation in urban planning and infrastructure management to provide a more realistic representation of urban areas and the built environment. A key concept in public infrastructure management is Life Cycle Asset Management (LCAM), which aims to improve the decision making in each...

Simplification & Visualization of BIM models through Hololens

Augmented Reality (AR) is the technology that superimposes digital generated objects on the physical world. It has the potential to create new products and services,like visualizing future buildings or objects that will decorate a place, which creates new opportunities for applications in both the public and private sector. The architecture and...
