Dimensions according to ÖNORM A 6241-2
ÖNORM A 6241-2 has introduced further dimensions for analysing and using building data, in addition to those already known:
- 2D = plans
- 3D = models
have been defined:
- 4D = time/scheduling: This dimension is currently mainly used for simulations (e.g. construction sequences), but a link to schedules is also possible.
- 5D = Costs: This is mainly used for model-based quantity and mass determination for cost calculation and the creation of specifications.
- 6D = Sustainability: information on the sustainability of a building over its life cycle is analysed here.
A further dimension can also be added:
- 7D = BIM and facility management: represents the linking of BIM information with operational and strategic facility management.
The dimensions are a good aid for categorising and dealing with the various topics, e.g. in the use cases.
