Mm, not quite, when say having 60+staff work in a single building model you need something that allows object locking so stag can work on part of a building and check it in and out.

I'm not the architect, I'm the sysadmin that designs and builds the server/network infrastructure for a half dozen architecture firms, some which have over 300 architects spread around Australia, Europe, and south East Asia. That mostly means running up servers to host BIM and BIM cache servers, as well as maintaining PIM servers.

To be honest I quizzed you because I honestly never heard of it and my life revolves around both revit and bim360, revit and revit self hosted bim servers, or archicad. Not that I do anything much in them, BIM managers generally administrate their own BIM instances and their teams. But some of the projects are in the billions of dollars that you'll find on featured on the b1m YouTube channel.

Id argue that while the architects themselves are by and far the largest cost, the largest IT cost is the modelling software. I've even had some people using unreal engine to do parts of their work now especially for customer facing flythrough demonstrations and city view with time of day and all that.

So I'm pretty open minded to keeping my ears open to new software since I'm never sure what to expect. It would be interesting to see if it could ever be possible to do one of these megaprojects in open source. But my gut says it's unlikely.
