					The BIM Concept




BIM= Building Information Modeling     Drawings, building views,
                                       visualizations, calculations
 Also known as „Virtual Building” or   and quantity take-offs are
 „Building Simulation”                 automatically derived
                                       from the 3D model.
Working Concept – BIM
   Single file concept: The complete
    building model and all of its
    representations are included in the
    BIM file
   Real architectural elements used for
    modeling
   Changes of the model affect all
    related drawings (and vice versa)
   Automatic generation and updating
    of documentation
   Architectural content (libraries)
   Building information data attached
    to the elements
   Additional materials (rendering,
    animation, quantity take-offs,
    schedules)
Evaluation– BIM
Benefits
    Compared to 2D and 3D CAD
       •   Elements have architectural meaning
       •   Changes on one drawing have
           influence on all others
       •   Rich visualization content (animation,
           sun studies, renderings etc.)
       •   Automatic quantity take-offs,
           schedules
       •   Connection to structural, energy
           calculation, collision detection etc.
           software

Drawbacks
    •   Higher training requirements
    •   Might be difficult to learn the BIM
        approach for people who were previously
        2D users
    •   Might be more difficult to handle complex
        geometry (e.g. freeform structures) then
        in 3D and 2D CAD
