Determine project-specific information required for the intended BIM applications and project objectives.  

Project specific


It is necessary to think project-specifically about the information requirement. The BIM base IDS alone is not sufficient to achieve all project objectives. Therefore, in order to achieve optimal collaboration and the best result, establish with the project team who shares what information, where and when. 

First of all, think carefully about the project objectives and how the process will be organised. By determining which BIM applications can contribute to achieving the project objectives, it becomes clear to what extent information must be incorporated into the aspect models. Depending on the organisations involved in the project, these BIM applications may entail certain conditions. Look, for examples at the BIM use cases on https://ucm/buildingsmart.org.

Examples of project specific IDS

There are several developments in the market that can serve as a basis for drafting a project-specific IDS. Examples of possible effects:


Geo-location is generally used to determine the situation of the building and to perform location-dependent studies, such as a solar study. The mutual coordination of the aspect models is very important, which is why it is included in chapter 3. Geo-location is not necessary for the combining of aspect models.


Every construction task has a time aspect, whereby the status of the objects provides some insight. This status can change over time. A project starts with a recording of the existing situation and ends with an as-built situation. This as-built situation then becomes the existing situation again. 

Property sets

Name and explain which project-specific information - such as properties (Properties), property sets ((Custom)PropertySets) and quantities (QuantitySets) - you will additionally provide.
