Use Case: Object statement basic elements (building automation)

By modeling all the basic elements required by the building automation in the different trades and providing the unit labeling system (ULS) key, an automatic element extraction per different disciplines and equipment’s should be possible, so that a rudimentary resource list is available. In a second step, all elements required for building automation (elements with electrical connection) are modeled.


• Increased planning quality and thus increased planning and execution quality • Time savings due to automation. • Position finding of the elements in the model • Field device plans Building automation with link to the equipment list


• Model-based recording of all elements of building automation in resource lists • Replace manual capture with automated process • Create simple field device plans from the model with in-phase information depth from the building automation side • Modeling of the elements enables linking from a control system or CAFM tool into the model for simpler fault elimination.


• Client-specific plant design concept • Centralized directories of attachments and names • Modeling Directive • Phase-sensitive attribute definition building automation


• Automatic assignment of unit labeling system (ULS) attributes to the elements • Completeness of the modeled elements in the model • Interfaces to building automation systems or CAFM tools

The use cases reflect the current best practice do not claim to be complete. Use cases shall be understood in the sense of a generally accepted recommendation or guideline from a legal point of view, but rather to support the client and contractor in the application of the BIM method. The use cases must be adapted to the specific project requirements. The examples listed here are not exhaustive. Information is based on real-world insights and is therefore to be understood as best practice and not universally valid.
