Why is "stamping" of plans illegal? I don't understand this. If plans are reviewed and approved by a licensed PE, whats the problem if they were not done "in house"? If the PE has the authority to make changes as neccesary, why not? I ask this because much of the design work in my field(construction industry) could be performed by someone not licensed. If the stamped plans pass all applicable codes what is the problem? I guess my question is what defines "under my supervision" in the PE disclaimer.
