Well, I saw at least one gentleman filming the sessions here at the Change the World convention yesterday. So its already happening.

I know that there have been a few presentations I wished I could hit the Fast Forward button on.

AIA could post these presentations on the web and learning credits for them. Then maybe you could justify charging for them.

The problem that we've been trying to work out in the Green BIM Network is interoperability between the programs. The examples Paul is showing were built in the analysis software rather than imported from a BIM Model. We need a dynamic link between the analysis software and our BIM software.

[Brian Kimsey]

I hadn't thought of it that way, but you're right. Many of the examples were of models built in the tools themselves rather than the BIM authoring software. Even when he did use a BIM from the native application, there was a lot of work (adding text descriptions of the glazing type, etc.) that was needed within the specialty application. We have to have a more intuitive link between the tools than the current state of the art supports.

Questions:
Moving information back and forth?
Scale- down the information most time intensive.
How much information is coming across from one platform to another.

Rarely pass geometry back to the architecture. Often parametric rules are given instead.

How to improve the workflow ?
Study the amount of information needed. 10 years from now we will have filters.

TAS? – proprietary software – reliable used by people who know how to use it.
Comes down to who is using the tool.

How do we convince clients that it is beneficial to pay for these services?
Engineers fees are based on conventional services. It is often not part of the fee structure for them to be involved early on. Extra scope and fee for Atelier 10 for Environmental consulting.

Explain the risks for the analysis?
Energy – the building may not perform as well
There are penalties in places like Florida if the building performs more than 10% less effective. This is not fare because performance is based almost entirely on how the building is occupied.

Do we qualify results with a factor?
Occasionally but more often we are very clear with what the factors are. More often than not we are comparing or suggesting a better alternative.

Are you hired by the architect or the Owner? Do you use BIM model yourself?
Hired by the architect as a consultant from concept phase forward through the project. Don’t rely on BIM because it is often faster to build the model over. We only want a small portion of the model and are looking forward to filters in the future that will give us these.

Acoustical Consultant – work with them early on to set up design rules. Are you finding that there is a fundamental set of principals that Architects could follow? More often than not we don’t need to do the analysis because we’ve been through it before. We work on hundreds of projects a year so we build up a level of experience faster. The most cost effective way to use our services is spot consulting at key points in the project starting very early on in the conceptual phase.

Paul, " We don't do Architecture because frankly their fees suck."

Great Presentation...Good information. Hope the presentation is online.

It is always disappointing to here that it is just faster to rebuild a model than import the BIM using CFCs. Architects always want it to be seamless and clean, but the technology does not support it. I am doing a D/B Bridging project, where both firms are using Revit, and the production firm is going to completely rebuild the Revit model because the design firm did not build the BIM in the way that the D/B production firm wants it built! Incredibly frustrating.
