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 answer questions such as identifying an appropriate HVAC system for a building based on room usage, outside air temperature, solar exposure and traffic pollution or validating whether a proposed built asset meets relevant planning constraints and support tasks that include logistics for construction, asset management, facilities upgrades, and road safety design improvements amongst many more.
From the data perspective, this integration raises the question of how to integrate very detailed design & construction data from the BIM domain with contextual geospatial data (both 2D and 3D) that models a very diverse range of aspects of the wider built environment and also underpins analytical analysis.
Developing a coherent approach to GeoBIM integration requires consensus between multiple stake-holders from both the Geo and the BIM side. Logically this is best addressed at the multi-country level, and is the topic of the new EuroSDR project on GeoBIM integration. The general aim of the project is to detail both the needs and the issues of GeoBIM integration, studied from use cases as well as from existing experiences in the participating countries.
The partners in this project (besides EuroSDR) are: Lantmateriet Sweden; GUGiK Poland, NLS, Finland; Kartverket, Norway; Agency for Data Supply and Efficiency, Denmark; Kadaster, NL; Swisstopo, Switzerland; Ordnance Survey, UK; Ordnance Survey, Ireland; IGN, France and ICGC, Catalonia. Apart from co-funders, these organisations are active partners in the project and they will carry out parts of the project. Also a few universities and research institutes are partners in the project, i.e. University College London, Dublin Institute of Technology, Lund University and the Delft University of Technology.
The project is divided into two phases. In the first phase, (November 2017-May 2018) aimed at making an inventory of the GeoBIM state-of-play in the participating countries by means of a questionnaire.
The second phase aims at the definition of a workflow and of the specific requirements of the data for managing GeoBIM information within two specific use cases:
The project is expected to finish end 2019.
