For years, Architects and in some cases Engineers have seen their project involvement slowly diminish as new niche disciplines take over parts of the project delivery process.  Once upon a time, an Architect would have controlled design, contracts, bidding and cost analysis, full contract administration, defects and more.  Many of these components have been trimmed away by quantity surveyors, project managers, and to a large extent Head Contractors.

Could Trade Contractors (in Australia these are often call Subcontractors) be the next group who starts chipping away at this scope, as they take on more and more responsibility for developing detailed BIM models (yeah I said it) for future projects?

Along these lines, you may have seen this tweet, where I quoted Steve Jones from McGraw Hill, speaking at the SmartMarket breakfast in Adelaide this week:

This trend is evidently not limited to just one country, as this quote supports: 
Contractors have now surpassed architects as the fastest growing adopters of BIM. Over the next two years, contractors expect the percentage of their work that involves BIM to increase by 50 percent on average…

Ryan Schultz is working on Revit–>IFC–>Revit translations, and he has created a open source page as a focus for test and sample files.  Here is the link:

Interestingly, Ryan is looking into IFC translations with ArchiCAD, Vectorworks, Microstation, Tekla and others.  The mixed environment of BIM software on collaborative projects is proving a challenge to many teams.  Ok, we can’t all work with Revit (maybe one day), but for now we have to find a way to share our models with high geometry fidelity and without losing the actual intelligence of BIM data.

I’m sure Ryan would be keen to hear from you, perhaps via Twitter or the github page.

Let’s work together to learn how to work together…


In a somewhat unexpected post, landarchBIM has described a method of inferring the movement of a Reference Plane that is driven by an angle parameter.  This probably falls outside of the “best practice” category, but it may be worth a read:

The key seems to be “that the plane must be constrained to the plane it wants to move along.”

Personally, I will probably stick to Reference Lines, because I don’t find them too difficult to understand or control.  But hey, whatever works for you!  Oh, and if you have any problems, contact landarchBIM 🙂
