Update:

The foundation company sent someone down to take measurements this morning and apparently the foundation hasn't really shifted that much.

Now the question is: why did the pipe break?

I have an appointment with the plumbing company this Friday to run the camera through the whole system to make sure there're no other leaks.

If the damage is localized to just that bathroom, instead of tunneling which is both labor and $$ intensive, maybe just let them punch through a hole in the floor to get to the leak.

I can fix broken pipe but getting to the leak is what I am not so sure about.
