This question was aked in 2015, whereas it was not possible - is there any update?
Is there any way to import IFC format into UE4? I need to import models wich has information attached to them and the only way to keep information linked is via IFC format.
Even if it could, I don’t know what it would do with the extra information in the file
A company has 3D-scanned a building and added applications/properties to all the objects using IFC format.
Example: a furniture desk has stored information like where the desk is bought, what maintenance it requires, what type of material the desk is made of, etc.
All the objects has information attached to them stored in ITC format. I want to make a software where I add further information to the objects and utilize this information in an environment (program) where I can navigate in the building, click on a specific object and read its content.
Do you get the idea darth? Could I utilize UE4 in another way to proceed?
When UE4 would import the file, all that information would be gone because there’s no corresponding type of file to store it with in UE4, the only thing that would be there would be the 3D geometry which would be a Static Mesh.
What would probably work better would be to export that information to an XML file–and then you would create something in UE4 that would read the XML file to load the info about the object. Might require some C++ but might be possible to do with Blueprints
Yes, or even create a PHP page that retrieves the information out of a database, then converts that to Json and sends that to a the engine. Might be possible purely in BP.
i think the solution is to find out how to create a"blueprint list" for IFC objects Guid, and make XML communicate with CoBie (a kind of excel) (exporter in xBIM) - please let me know if someone have the solution…!
alot of work for the one that have a solution. 
it will make a greate step, and it`s the big question about IoT - and userfriendley 3D graphical interface- the market will be bigger than games
I know it is a couple years since original post but this is the most recent Info I can find on this.
March 2018: We are looking into IFC. I think we will have to support it eventually, but it isn’t on our roadmap so far.

Support for IFC import is starting development.
