Hello Timothy, at the University of Birmingham within the Estates Office (and other organisations I have worked with/for) we have chosen to not ask for IFC file types. This is something we have been challenged on regularly, however we still see this as being the most appropriate solution to the problems you have outlined.Â
Forgive me as I don’t know much about the organisation you work at, however, are you bound by legislation to ask for IFC only? We have written in out our BIM Requirements and contracts to ensure the native Revit files (for all disciplines – Architecture, Structure, Landscape, MEP, AV, Civils etc) are delivered to us throughout a project and for final delivery. These are verified, as-built models to a level of precise accuracy. It has taken a bit of time (and not been easy) to get to the point where this is now accepted as the standard delivery mode for the University, but we are there now.Â
The argument against this is that we “should be open” – but IFC file types ae not fully stable in my experience, and unnecessary when you “edit” BIM models regularly – as we do without the support of consultants, to operate our estate.
Hopefully this is useful support for you, but also really happy to discuss further. If you operate an education or health estate it may be worth you joining the BIM4Estates group – let me know.
All the best
