Certain parts of a building can and sometimes must be described using standardized parameters that describe the product quality in a measurable manner such as concrete quality ratings. However in terms of BIM I would like to see the possibility to actually document what has been measured on site (e.g. concrete slump test). It is basically a more detailed way of storing the model “as built”.
Is IFC already capable of storing such real-life values of measured parameters which are obviously not available at design time?
