Description

User Story Description

Urban planning authorities have to instruct application for permit to build coming from BIM contractors, and check the conformance with urban planning rules (UPR). The use of BIM models encoded in IFC will become mandatory for important building projects.
The proposed building project (provided as a BIM and encoded in IFC) should be:
- validation against urban rules planning (this process should be automated)
- validation with human verification; the analyst should be able to view the building project within the existing 3D model of the city.

Once the project has been validated and realized, the BIM data needs to be added to the exiting 3D City Model or database, according to local city rules, with mappings to the various LODs. The provided BIM data should also be stored with links between the geospatial data (at feature level) and BIM data.
