I watched some of this today, from the buildingSMARTalliance.

Dr. East makes the point throughout, from an owner/operator point of view for FM and for building performance control, that you use the data you have, and you alter/ammend it to suit new testing/performance requirements as they arise.

He also makes a strong case for open standards in data format (for data longevity)

The main point in the presentation, I think, is support for a standardized list of the categories of what should be included in a BIM.

For example, equipment should be included, and information about service requirements (electrical service, for example)

The whole presentation is here 

Throughout the presentation there is an appeal for consistently applied standards of item identification. One of the reasons discussed in the presentation is that without standards, the BIM really just becomes an impenetrable jumble of information within which nothing can be found and no sense can be made. So there is an appeal for good attribution techniques.

For me, I have the same motivation, having myself built BIMs for years, it always seemed to me that anyone who had to look at the model, to see or understand or find anything specific, would have a difficult time, because undoubtedly Dr. East is precisely right: a model is a dense jungle of information.

There are two machetes we use to whack through that jungle, to get somewhere, and make sense of things. One of them is: we arrange things on drawings. The other (and these often go together) is, we develop and adhere to standards in data attribution.

Both of these have the same purpose. They help us find things and understand what we’re looking at.

I’m doing work on both of those, but the one I always talk about here is taking the idea of drawings (directiveness), as a tool, and carrying that with us into the modeled environment where its more effective than when it is abstracted outside of that environment. Drawings are extremely useful as a tool for understanding complex things, but at the same time, not as useful as they should be, hindered as they are by their abstraction.

So I want them back in their environment, where they do what they do, better (Directiveness in AEC: BIM means little without it)

And when the drawings are in there like that, they do their job, years later, when other people come walking through the same information jungle (the model) wondering where anything is and how to make sense of anything, and these drawings will be in there, helping show the way. http://www.youtube.com/watch?v=aqLDk8gO1Yw

New kinds of directives will be added along the way (after construction) as needed, to direct attention to information and what needs to be done.
