Seriously, when will the design professional have an ASSE 6000 series related credential?
Most problems I have seen in the past few years has less to do with installers, inspectors and verifiers. Design professionals with PE after their names have not been on board with the code. Their mistakes or misinterpretations have a much larger impact on a given project than any of the other disciplines mentioned above.
I am a Licensed Respiratory Care Practitioner in California but there was still a learning curve I had to prove to become a Medical Gas Verifier.
Fair is fair.
