Thanks for the replies. I should have given a more detailed
explanation of why I asked. I got into a little cat-fight with a
consulting engineering firm over fabricator's shop drawings which were
to be sealed by a P. Eng. The contract drawings showed connections with
very little detail, i.e plate sizes, but no weld sizes, shear forces but
no axial forces, eccentric loads on connections. I wrote to this firm
and requested the member forces which are required by our national
specification CSA S16.1 "Limit States Design of Steel Structures". A
person wrote back in an unsigned letter that I was to just follow the
contract drawings and seal the shop drawings. I replied that under no
circumstances would I seal the drawings with the information supplied
and explained why, and I also asked if he or she was a structural
engineer since I suspected I was dealing with a "civilian". He took
great offence at that and accused me of unethical behaviour. I wrote
back and suggested he look in a mirror. I am still awaiting the forces
acting on members.
As a side-light to this, I contacted the Professional Engineers of
Ontario (PEO) and asked the guy in charge of "standards and practises"
what happened to a planned committee on the long on-going dispute
between fabricators and consulting engineers over shop drawings. We
discussed the issue in general and he asked me what the USA uses for a
steel specification. I should really have referred him to your code of
standard practise which covers this issue of shop drawings better than
anything up here. I copied the relevant piece from the AISC 9th edition
and e-mailed it to him.
