Architect acting as a structural engr and doing extremely poor job
(OP)
I was asked to take over a project because the architect refused or was unable to provide enough detail to produce bar joist shops. I've just scratched the surface but already have found columns that are at 200% of allowable stress and the specifying of a 26 ga roof panel with no published diaphragm values. The panel is produced by Metal Sales, was originally a wall panel, had one test performed in a diaphragm configuration in 2006 and even using those values the diaphragm is at 350% of allowable. I feel I have no choice but to send a letter to the State Board of Licensure (this is in Colorado) informing them of this. I don't know if this guy has designed any other commercial buildings but the idea scares the hell out of me. This is the first time I've ever had to do this. Any suggestions re: language I should use?

Go through everything structural in the plans with the intent to document and reference each of your reasons. I would suggest that you make a table of design defects, cite the appropriate code provision for each and explain why your analysis shows a breach of acceptable practice.
Remember that many structural mistakes never get brought to light because the structures rarely are stressed to code levels. Every deficiency in structural design requires that the construction approach perfection...which we all know will not happen...and even then failure can occur if the breach is egregious enough.

Some architects are competent in engineering - most not so much.
AND my favorite is Illinois. I can't so much as design a simple I-beam w/o an SE license but ANY architect can. Go figure. And I live about 30 miles from Illinois - I am sure the laws of physics and engineering change when you cross the Mighty Mississippi!!

Good idea

But it may be best to talk to a lawyer (if you can find a good one) first.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.

So far the roof joists and beams are oversized. The roof diaphragm, the columns and masonry walls are under designed. So if enough sky hooks and wall braces are used everything should be fine.

MiketheEngineer: The problem is that you should have just become a computer science programmer so you can call yourself an Architect and Engineer all in one title and everything will be okay. I think I can actually make a proof of that.

I wish they made Gerananimals for men so I could dress myself appropriately..... or least good enough so that my wife doesn't laugh at me.
That's why I never ever even got close to becoming an architect!!!
As I tell my wife - "I don't do colors" - "You pick it out and I will paint it" - "BUT never ever ask me if it looks good - because I REALLY don't know!!"

I haven't met one yet. There may be some who understand the big picture stuff pretty well. But there is more to structures than member sizing.
