Advanced information modeling

Define your BIM model in detail

The information modeling takes place simultaneously with the design based on specific customizable settings.
The structure of the model, the elements that compose it, the geometric representation of the objects and their information content are defined.
The integration of buildingSMART's IDS (Information Delivery Specifications) and bSDD (buildingSMART Data Dictionary) standards directly into parametric information modeling enables easy and intuitive creation, management, modification, and validation of information content, ensuring data consistency between project, information model, and information requirements.
Thus you create an information model according to the specifications required in the BIM Execution Plan (BEP).
The information model is created while maintaining information consistency with all the information documents created.
The activity of multidisciplinary collaboration is supported by the implementation of the BCF (BIM Collaboration Format) standard, facilitating both design integration and BIM collaboration.
