Guler, Dogus (author), Alattas, A.F.M. (author), Broekhuizen, Marjan (author), Kalogianni, E. (author), Kara, A. (author), van Oosterom, P.J.M. (author)Τhe built environment has a vast and ever-growing number of complex and multi-layered buildings and other structures. The number of those is growing because of the increasing pressure on the limited space in cities. It is important to note that different professional sectors are involved in the realization of a new building. These sectors are...conference paper 2022

Krijnen, T.F. (author), El-Diraby, Tamer (author), Konomi, Theohar (author), Attalla, Ahmed (author)Multi-disciplinary three-dimensional representations of building designs are available in BIM. However, thermal analysis often remains a manual task due to disparities in modelling: In IFC, buildings are decomposed into sets of elements with individual solid volumes. Thermal analysis requires interfaces between pairs of adjacent spaces.<br/>In...conference paper 2021

Hesselink, Geert (author), Krijnen, T.F. (author), Pannekoek, Geert (author)In this paper, we discuss an automated procedure to automatically analyse and extract domain specific construction information from IFC building models. More specifically, we were interested in extracting location potential placement sites for thermal bridges between balconies and their neighbouring floors. For this aim, we developed a web-based...conference paper 2021

Berlo, Léon van (author), Krijnen, T.F. (author), Tauscher, Helga (author), Liebich, Thomas (author), Kranenburg, Arie van (author), Paasiala, Pasi (author)The buildingSMART Technical Roadmap, published in April 2020, was the start of multiple modernization efforts for buildingSMART Solutions and Standards. The modernization, modularization, and normalization of the Industry Foundation Classes (IFC) is one of the priorities. A taskforce has been working on restructuring the core of IFC for the IFC...conference paper 2021

Luttun, Johan (author), Krijnen, T.F. (author)Recent progress in computer vision and the pervasive use of Building Information Models (BIM) in the construction industry provide countless opportunities for decision making in architectural design. It allows capturing real-world geometrical data for assessing design options, such as windows products for replacement on the façade of an existing...conference paper 2021

Ramlakhan, R.J.K. (author), Kalogianni, E. (author), van Oosterom, P.J.M. (author)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...conference paper 2021

Krijnen, T.F. (author), Noardo, F. (author), Arroyo Ohori, G.A.K. (author), Ledoux, H. (author), Stoter, J.E. (author)The Industry Foundation Classes are a prevalent open standard to exchange Building Information Models. In such a model, geometric representations are provided for individual building elements along with semantic information, including a significant amount of properties related togeometry and explicit topological relationships. These...conference paper 2020

Luttun, Johan (author), Krijnen, T.F. (author)The Industry Foundation Classes (IFC) cover a wide variety of subdomains in the construction industry. Model View Definitions (MVD) enable to specify a subset of the IFC schema to assess the content of a model for specific use cases and information exchanges. However, IFC and MVD paradoxically complexify the workflow since it requires a deep...conference paper 2020

Gkoika, Maria (author), Coenders, Jeroen (author), Nijsse, R. (author), van Nederveen, G.A. (author), Pasterkamp, S. (author), Rutgers, Arend (author)This paper presents a novel approach to modelling and documenting design knowledge: to use parametric technology to explicitly store knowledge which exists in a group of people (such as a company), so that it can be reused over many projects and grow over time when more projects are designed. This approach has been applied and tested on a test...conference paper 2019

Chiang, Y.-C. (author), Borgart, A. (author), Li, Q. (author)Membrane shells, which have minimized bending moments under certain load conditions, are regarded as ideal structural forms in terms of material efficiency. Most of the existing numerical form-finding methods are based on discretizing membranes into finite panels or funicular networks and focusing on gravitational loading only. In order to...conference paper 2019

Ellul, Claire (author), Stoter, J.E. (author), Harrie, Lars (author), Shariat, Masoome (author), Behan, Avril (author), Pla, Maria (author)In both the Geographic Information (Geo) and Building Information Modelling (BIM) domains, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step in facing the multi-disciplinary challenges of our built environment. The result of this integration – which can broadly be termed GeoBIM –could...conference paper 2018

Vrijhoef, R. (author), Dijkstra, Jan Tjerk (author), Koutamanis, A. (author)This paper presents a research endeavouring to model site work in a 4D BIM model. Next simulations are performed with this model in 5 scenarios including specific interventions in work organisation, notably changing positons of facilities for site workers. A case study has been done in a construction project in the Netherlands. The research has...conference paper 2018

Khoshelham, K. (author), Díaz-Vilarino, L. (author), Peter, M. (author), Kang, Z. (author), Acharya, D. (author)Automated generation of 3D indoor models from point cloud data has been a topic of intensive research in recent years. While results on various datasets have been reported in literature, a comparison of the performance of different methods has not been possible due to the lack of benchmark datasets and a common evaluation framework. The ISPRS...conference paper 2017

Xu, Man (author), Wei, S. (author), Zlatanova, S. (author), Zhang, Ruiju (author)At present, 87 % of people's activities are in indoor environment; indoor navigation has become a research issue. As the building structures for people's daily life are more and more complex, many obstacles influence humans' moving. Therefore it is essential to provide an accurate and efficient indoor path planning. Nowadays there are many...conference paper 2017

Oldfield, Jennifer (author), van Oosterom, P.J.M. (author), Quak, C.W. (author), Veen, Jeroen van der (author), Beetz, Jakob (author)Much work has already been done on how a 3D Cadastre should best be developed. An inclusive information model, the Land Administration Model (LADM ISO 19152) has been developed to provide an international framework for how this can best be done. While this generic framework encompasses a wide range of eventualities, it does not prescribe the...conference paper 2016
