There may be a coordinate issue, but if you look at the two screenshots, it seems obvious to me that your bearings in Civil3D are not the same as FreeCAD.
I think your initial tangent was around 12 or 13 degrees. It looks to me like your Civil3D alignment starts at 12 or 13 degrees counterclockwise from East. In FreeCAD, the alignment starts at that same angle, but clockwise from North.
Anyway, once the angles are certain, we can sort out the coordinate issues.
As for the coordinates, FreeCAD uses mm as it's base units - at least that's how it seems to me - so all of your alignment coordinates are multiplied by 1000 accordingly. I'm guessing you aren't doing that with your surfaces?
