Hi Dave

I definitely would have two level certification. One for the use of the program (Building model) and the other to figure out the design and analyze the results. First part is definitely for COADE certification but the other? Where to draw a limit certifying a CAESAR II expert and where true piping engineer?

If I would be a boss of a company supplying large number of design calcs I would definitely have two level people working on a pipe stress program. Those who can build a model and those who can analyze it. Reason for this is pure cost and availability. It is easy and quick to train model builders but you still need to know their skill level. To find one who is a pipe designer or train one is a different issue. As the plan is to have CAESAR II certification so maybe the limit would be that the "engineer" should be a CAESAR II guru. Anything over this is for professional engineering bodies.
