GUID

You can export to IFC with Openroads, but Bim360 (and all Autodesk products) can't read the IFC version that ORD export because it export it in the latest version (that nobody use yet).  I don't know of an easy way to do this because Bim360 does not read that much information and or format.  

One way could be to assign Item Type to your corridor defining all the parameter that you want, export you corridor to DWG, export your item type to excel. 

Then with civil 3D use a Dynamo script to remap your item types to custom properties from the excel file to the exported corridor.  The element ID of the different element stay the same once exported.  The script is given with civil 3D and dynamo.

Or tell your client that the information is in the layer and build your corridor with good layer name?

You can also export you corridor to an Imodel, open it in Navisworks, the Inside Navisworks links the element property (element ID) to an Imodel database to have access to the different corridor elements, there are some post about this workflow in this community, again nothing easy and no push button...  Then you put your Navisworks file into Bim360.

Good luck and if you find an easy solution please post it in this forum.

This GUID IFC issue was addressed in OpenBuildings a few versions ago so I hope this will make it to OpenRoads:

As far as im aware the GUID in ORD IFC exports is randomised on every export, but im not 100% sure. I think you should request this via a ticket or the Ideas forum.

Also, FME 2020 can now read Item Types from DGNs so you could try that to convert to a format compatible with BIM 360 maybe?

Good call Mark about FME, I didn't think or knew about this. 

I can not find the option to export as IFC. I am using OpenRoads Designer Connect edition 2020 Release 2

Try the Home Ribbon Tab to the right or Ribbon search IFC
