Theory and representation

Theory and representation 

BIM may seem to stimulate progress but in some respects it restricts progress. In the bad old days of CAD, no-one dared suggest that CAD was anything more than a technology. This created room for theoretical and methodological development as a complement, as the underlying reasons for using computers in architecture or at least as an intelligent approach to an enabling technology. The old diptych of design and drawing was interpreted as theory and representation, allowing room for exploration that did not necessarily fit the priorities or limitations of the technology.

By being both a technology and a methodology, BIM restricts this room to within its own framework. It forces one to work with a representation that often disappoints and requires much loyalty concerning key methodical aspects. In this sense, BIM is an old-fashioned technology and approach, a largely closed (proscriptive) system. It doesn't help that the current implementations are lacking in many respects, for example the central issue of shared models: to be able to collaborate online, people have to make many concessions concerning the size of files etc.

This brings us to an interesting situation: the currently dominant technology, which theoretically promotes inclusive integration and appears progressive, seems to exclude further development and variation. Of course, some would argue that add-ons, especially parametric programming tools, allow us to solve many problems but that's not the best way forward, especially concerning representation. If BIM has given us a usable theory of design, we now need a better theory of representation.
