It sounds like the cart got put before the horse here.
What work did you do? What was inspected? What was the permit for?
It seems reasonable that there be, somewhere, some paperwork that answers these questions.
No 'stamped' plans? No problem. Along with the EC license comes your authority to make your own sketches and sign off on them. These are usually included when you apply for the permit.
You can also include 'cut sheets,' information regarding specific appliances and their loads.
