||Constraints of product modelling approach in building
||The ultimate goal of building product modelling has been to define the datastructures that could be used to describe our entire built environment. Inspite of the huge size and complexity of this task, the theoreticalfoundations of modelling received little attention. In the paper thetraditional foundations of the modelling approaches are questioned. Anunorthodox perspective on the computerised representation of the real worldis introduced. The view is based on Heidegger's philosophy and Winograd'scritique of artificial intelligence. The author exposes the difference betweenthe modelling of material phenomena (such as in structural mechanics) andthe modelling of knowledge and information. He makes a distinctionbetween physical models and anthropo-technical models. He claims that thelatter are not objective but subjective. This is the major constraint in usingproduct model technology in building. The author concludes that buildingproduct and process models do not model objective reality but themodeller's subjective understanding of that reality Therefore several correctbut different models may exist. Based on the analysis the followinginformation technologies look promising: simple generic models that allowroom for different (even wrong) interpretations; generic software that allowsuses outside the intended scope; friendly software that does not build abarrier to engineer's being in the world; non model-based software tosupport creative design; communication software to support commitmentnegotiation instead of information exchange. Complete product models andproduct models for creative design are not possible.
