Shop drawings 3

[volunteera]

What would be the best method to teach how to produce structural shop drawings? Can anyone advise some good books or references?

Thanks

ACI and AISC both publish detailing manuals that would be excellent resources. What materials are you primarily interested in?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Start reviewing shop drawings...a lot of them. All shop drawing submittals have flaws, but after you review a few dozen of them, you get a sense of the good, the bad, and the ugly.

"All shop drawing submittals have flaws"

I think most detailers would say the same about engineering documents.

This isn't a competition. All construction drawings have flaws, as well. I didn't say that they do not.

Before your butt got hurt, my point was that in order to understand how to most effectively produce shop drawings, it is good to get a feel for the do's and don'ts found whilst reviewing many of them.

The same logic can apply for improving producing construction drawings. I am always looking at others' construction drawings to improve my own.

I think you need to expand on your question. Whom are you trying to train? Engineers, technicians or is this somehow related to your screen name? Are you in a college setting or are you a practicing engineer? If the later, I presume you already know the technical requirements so it is unclear what aspect you need help in. This segment of the forum tends to focus primarily material strengths (member sizes, connections, forces...), and while that is important, it is not the biggest challenge in accurate shop drawing production. The type of software, staff experience and client requirements can be a bigger part of the problem.

Just for the record, I'm not "butt hurt" or offended by your post in any way. I'm a licensed structural engineer who has had done everything within my power to try and produce a good set of drawings. Sometimes, depending on the project, it's just not in the cards.

There can be a lot to Shop Drawings. Some contractors use them to gain tacit approval of alternate (and cheaper) details that the reviewer frequently doesn't catch. And we all know of the shop drawing prepared by a bored drafter showing a toilet in the middle of a hallway that only gets caught when someone inquires about the sanitary outlet in the middle of the floor during construction.

I second the notion of an engineer learning shop drawings by reviewing them. Experience gained by reviewing them and comparing them to the structural drawings is second to none. At first, the new engineer will always be very thorough until they get the hang of it and they learn what the acceptable alternatives are and where the critical areas to check are. If the engineer is also a beginning design engineer, they can get great benefit of seeing how the certain conditions are best detailed.

My experience- good (general) shop drawing preparation requires knowledge of drafting and any drafting standards pertinent to the work, knowledge of the software used, knowledge of the subject matter, including all technical/code requirements, some knowledge of the economics of the work, knowledge of erection requirements, knowledge of safety requirements, adequate math and geometry skills, a bit of artistic talent. How you teach all this depends on what the person already knows. On the drafting/software end of it, check at your local junior college or with the software supplier for classes.

On the reinforcing steel side, CRSI fabricator-members have access to comprehensive, online detailer training. The program takes new detailers from basics through industry-standard detailing practice.

Thanks to all for comments. My goal is to train 1-2 years' young draughtmen. They have been practicing mostly in office environment.
Reviewing shop drawings will definitely be an option but sometimes guys are like opening a pandora's box where a good guide explaining in details helps a lot. Personally i think, taking a place in fabrication process is the best training guide to shape them in.
BTW, i do not agree with that all shop drawings have flaws and even there are some i would call them learning curve rather than mistakes.
