Blacksheep,
I stated:
Appropriately delegated engineers (or other such delegated persons) can approve said designs, repairs and modifications.
"Or other delegated persons" means persons other than engineers that are delegated to approve designs. So yes, you don't HAVE to be an engineer to take on this particular role. But "approving" a design on behalf of the administrator is a bit different than approving a design on its technical merits.
Being a signatory (or delegate) doesn't make you a P. Eng.

Please try to sober up before you post and "remove all doubt" of exactly how big a "fool" you really are. In other words, this is a very civil discussion, let's try to keep it civil.
