Cities and BIM (Virtual Bldg)

[Rakela Raul]

Most of the Cities have consultants: architects, engineers, etc...and all consultants must submit their work to the City following guidelines like the AIA Cad standards and the like:
Do you know any City that already incorporated BIM guidelines??

tons of thx in advance

[Rakela Raul]

cmon guys, please one at a time !!!

i just spoke to one of the IAI board member and i realized that this is really new...
but it will happen at city level shortly
thx u

I am not sure about any cities in particular. I do know that the federal government is adopting BIM as a standard and there is commission right now that is regulating what those standards should be. Soon state governments will follow. How soon I am not sure but you are right, this is going to happen.

correct..

im learning as i go..the site above is a good starting point x me.....thx

Our city uses Microstation. Anything that is not Microsation, in their view, is inferior, such as AC-generated shadow studies, etc. I can't imagine them adopting BIM protocols anytime soon. As long as your project can port into their mega DGN file, that is all that matters.

The problem is, we have had a hellacious time trying to import the city's DGN file into ArchiCad, whereby we get recognizable, complete, 3D elements. It just spits out a chaos of unclosed, indeterminate polygons. We have tried everything, capping stuff off in 3DS, etc. Nothing works. Microstation cannot export anything but DGN or DWG. How lame is that?

I say all of this, because even though MS is a full-blown BIM solution, it doesn't play nice with AC, so I can only wonder how any kind of BIM standards can come to be??

thanku Andy,

another big problem is that you cannot force the cities' consultants to use a BIM solution (for now), difficult to impose that kind of investment to 'minority' consultants...but you can enforce standards to follow instead and this is when the IAI . IFC come into play and somehow BIM begins to show.

im in the process of putting my neurons together first and try to see this thing from abv

IFC?

[Andy Thomson]

Are you saying that MS9 can export IFC? And import?

I am asking.

Archicad definitely can, Revit can, even ADT can. Not having that is quite incredible.

My last experience dealing with Bentley (very frustrating by the way, ZERO tech support or assistance unless I owned a license, they debugged the file, gave it back to us, still garbage), we got multiple versions of the DGN and DWG exported from The City of Toronto (various versions, export options) and dealt with just about every tech person I could get in touch with, but basically we had no recourse to getting clean, sensible model output from Microstation, into ArchiCad. We even went as far back as AC7 to see if it could handle earlier DGN export any better. Nope. You had better believe we tried every form of import to AC as well. We had 4 people in our office working on this. The issue had to do with non-co-planar polygon edges, and tops of buildings not closing - which we tried to fix with a command in 3DS to no avail.

At that time (last year) I was in utter disbelief that (MS) would only export a DGN or a DWG - NOTHING else, I believe these were both versions 7 and 8. The quality of it's DWG was so bad we tried to open it in just about every program you could think of, Rhino, Revit, 3DS, Maya, Sketchup - not a single one of them could even open the file - only ADT, and the results saved out again, after extensive purging, simplification, audit, etc. gave total garbage in ArchiCad.

Every time I hear the word Microstation now I cringe.
