Does that constitute the practice of engineering under Georgia state laws?
Is there anything exempting the person or the item under Georgia state laws?
In practice, there is probably a fair bit of engineering done that should be sealed (& done by a licensed PE) that is not.
Note that there are a number of exemptions which vary from state to state, but including for example, manufactured products, designing improvements to one's own property, utility construction, federal work, etc., and it can take some research into a state's laws to determine what exactly is required.
