You should always setup your project at the origin, setting up a long way from the origin will increase errors in the project and also lead to inconsistencies as you are experiencing.
This problem exists in most CAD and BIM packaged as the database where all info (coordinates and other info) only has a limited length of fields, so by adding a stack of numerals for distance from the origin before the decimal point you limit the number after the decimal point.
If you need to reference a survey point you can use the coordinate library part and input required survey coordinate info into that
I also like having the origin as a logical point on my model (generally two first grid axis meet there), it helps me see odd dimension input right away in the coordinate box when I am modelling things.
Yes, I agree we should never have models use the Civil coordinates. Someone didn't think it would have any issues when creating the file, when I realized it was that far away it was too late in the process to change. In retrospect I probably should have done it anyways and bite the bullet.
That is how I like to set up my projects too, when I get to start them.

Yes, but then all the layout views need to be redone and section/elevation have more issues as things aren't all linked to the model, so you would need to move everything in each of those views.
On top of it all we had already sent coordination DWG and IFC models with coordinates for our point clouds. So its more work for everyone which is why I didn't and still wont do it. We are in CA now so it's not worth it.
