BIM2FM – What other topics could be discussed?
As a responsible person for Building Operations, please do not worry too much about BIM. The world will not be re-invented in this field, even if you could get the impression it would.
In any case, it is your individual and long-term experience that tells you what you really need for your ongoing building operations. And yes, it is true that it is somewhat toilsome to put all that experience in writing to keep it in a respective BIM manual. Please do use your existing and well proven set of tools in this context. You know perfectly well which attributes you support in your CAFM system for the various object types. If these attributes will be taken over in the 3D model during planning, you will have made half the deal already. In addition to that, all your structures are defined there too, and you know which information you will need to build up the respective hierarchies. The only thing you need to keep in the back of your head is the fact that geometries will not be sufficient.
Thanks to the IFC standard, the possibilities to get data out of the 3D model are manifold. Regardless of whether you would like to take over the entire model, provided you have got a reasonable use case in place, or if you just want to extract data: as long as you are working with ruled-based import mechanisms, the data will be taken over with fairly reasonable amount of work. In case someone really continues to look after the 3D model when the construction phase is over, you can synchronize and take over data another time via existing re-import mechanisms. In the same way as when working in 2D, the only thing to do is to respect which data are the leading data. Thus, you have carried out a proper documentation for your objects including all respective modifications on the time-line and your additional data remain untouched.
Just relax a bit and get on BIM without too many worries. In fact, not many things will change anyway. One day, with technology evolving quickly and computing power improving significantly, we may probably work in 3D even daily. Or the bubble bursts, as many others did before, because something else, far better and more effective, is just a click away.
