Building/City Information Model for Simulation and Data Management
Abstract
This publication is related to a research partnership between the CSTB (Centre Scientifique et Technique du Bâtiment) and the territorial administrative authority of Paris La Défense, regarding multiscale model management and interoperability processes. The project included several steps, starting with the semantization of building data but also information for infrastructures and street furniture. Then, a standard BIM urban model (or City Information Model) has been structured and enriched to address a set of simulations carried out on a pilot urban area. The research challenges were to define data dictionaries, pivotal models and replicable simulation methodologies using the CityGML format and then to integrate them through a multi-scale collaborative format into a database system. In that sense, the objective was to study the potential of BIM as a vector of simulations data for the urban scale.
