| Basic data          | All data that is the basis for a project, often used as a designation for various map sources.                                                                                                                                                                                                                                                                                                                                                                                                       |
| BIM                 | BIM; Building Information Model is an integrated method for better administration of data and information flow by digitizing a railway facility throughout the life cycle. BIM is both a model and a working methodology, and must be central in all the project's activities and collaborate between all parties in the project. This includes information exchange based on open standards and model-based work processes for better quality, communication and handling of data and information.  |
| BIM models          | In this document, "BIM models" are used as a collective term for basic and professional models                                                                                                                                                                                                                                                                                                                                                                                                       |
| Basic models        | Models that describe the existing situation - terrain, ground conditions, objects and defined areas or places.                                                                                                                                                                                                                                                                                                                                                                                       |
| Professional model  | Models that describe what is to be built. Each subject has its own model (s) that contain only subject-specific elements.                                                                                                                                                                                                                                                                                                                                                                            |
| Coordination model  | A model that links all the professional models and basic models to a common model. It shows all the models together where you can see and compare the entire project together, and is the basis for other display models and result models.                                                                                                                                                                                                                                                          |
| Display model       | Coordination model that is adapted for use as presentations in various forums such as design meetings, public gatherings, approval and consultation rounds, etc. The visualization model contains generated defined surfaces / textures that give the model a reality impression and allow movement in the model.                                                                                                                                                                                    |
