Darned good call John.
I'd not only go back to the customer, but I would contact the person that drew the plans too.
Keeping your mouth shut only ends in arguments further down the track and doesn't help anyone.
With respect to showing up on a job you never got, that would be way out of line here.
To start running the guy down that did get the job would not only be un-professional, but it would also be wasting your billable time.
You would be losing on both fronts.
