1 The Quiet Revolution in Building Design and Construction: BIM

2 Building Information Modeling

3 BIM Definition Building Information Model "Building information modeling integrates all of the geometric model information, the functional requirements and capabilities, and piece behavior information into a single interrelated description of a building project over its lifecycle. It also includes process information dealing with construction schedules and fabrication processes."

4 Conventional design document creation

5 Design documents over lifecycle of a building

6 Communication structure in AEC

7 Building information model paradigm Building is designed assembling parametric objects that are related to each other Every object of the building has a set of properties that can be interpreted in different contexts Geometrical representations (e.g. drawings) are only one of many aspects. Drawings can be generated dynamically from existing data. Changes to the model are reflected in all depending documents Different domains (structural engineering, building physics etc.) have different views on a building model

9 Non-parametric building elements Window as non-parametric geometry: ●When size of window is manipulated by scaling, the profiles of the window frame are scaled as well ●Each part of the frame has to be adjusted ●Many operations are necessary => time and errors

10 Parametric Windows in BIM / CAAD packages: Revit

11 BIM: Relationships among objects

12 Building information model paradigm Building is designed assembling parametric objects that are related to each other Every object of the building has a set of properties that can be interpreted in different contexts Geometrical representations (e.g. drawings) are only one of many aspects. Drawings can be generated dynamically from existing data. Changes to the model are reflected in all depending documents Different domains (structural engineering, building physics etc.) have different views on a building model

13 Different representations of parametric objects Low detail 1:100 Medium detail 1:50 High Detail 1:50
