Surveys are typically the owner's responsibility unless you have specific provisions in your contracts with the architect and G.C. to the contrary (unlikely), so this will end up being a fight between the surveyor and the owner over the cost of the change.

This kind of stuff ALWAYS happens on design-build jobs. It's generally not a very good way to work (quality control suffers due to compressed timetables) and one of these days people will start figuring that out. For now the owner will have to eat it and pay the G.C., hoping to recover the $$$ from the surveyor's insurer later - that's what I'd expect anyway.

Sorry to hear about it.
