Building Information Modeling for a Smart and Sustainable Urban Space

Conclusion

BIM (Building Information Modeling) represents a major innovation in construction engineering that is based on a new business paradigm leading to major changes in the way buildings are designed, constructed, managed and operated. BIM has environmental, economic and social components that must be integrated into a larger space, putting the building in its geographical and urban context. This is how the concept of multi-scale BIM emerges to integrate different spatial and thematic dimensions in the intelligent and sustainable management of the city.

Multi-scale BIM must capitalize on a very rich urban knowledge by taking advantage of data models developed for BIM and 3D GIS (Geographic Information Systems). There are two perspectives when it comes to development. The first relates to 3D acquisition, modeling and semantic enrichment to produce the 3D base of multi-scale BIM, where different dimensions and scales of analysis are integrated. This requires the development of processing, storage and visualization methods adapted to the massive and heterogeneous data of the urban space. The other perspective focuses on the integration of multi-source geometric and thematic data, often distributed among several actors, in different formats and models for the geometric construction and semantic enrichment of digital models.

The challenge is even greater when it comes to interoperability, format translation and the development of formalized processes for exchanging data and ...
