Shop Drawing Review 1

[ohiowater]

Greetings,

I am looking to get some young design engineers engaged in shop drawing review, primarily for water/wastewater treatment plant equipment, piping, valves, and pumps. I was hoping to find an established shop drawing review checklist that will help guide them in their first endeavors so they can better ascertain how to perform a complete and appropriate review of shop drawings that may involve multiple disciplines.

I have checked EJCDC and AIA websites, but found nothing useful. Can anybody offer a suggestion on where to find such a checklist so I may share with these engineers. Thank you.

The best-organized shop drawing reviewers in our place review the submittals against the drawings for dimensions and physical type information. We had a case where a vertical turbine pump can was submitted too short. It was clear on the drawing, clearly wrong on the submittal, yet still got through.
For the specification information, they'll get a copy of the specification and a highlighter. They go through the submittal and highlight each piece of information in the submittal that matches. When everything is highlighted in the copy, the submittal is reviewed.
I don't think you'll find a nice checklist. They need to check everything that's in the contract documents. That's their checklist.

I have worked as manufacturing engineer, reviewing drawings, design engineer and metallurgist. To me, this require a lot of experience. People have to know the products, general manufacturing processes and drafting practices to do a good job of reviewing drawings.

What I am doing to review a drawing is to follow machining steps, then if you are missing a dimensions to cut one feature you know where is the problem. This way, you can catch almost all the missing dimensions if they are in 3D model already. To catch design problems, one has to assume design engineer role to come up with improvement ideas.

I TOTALLY agree with salmon2!!! ...This is one of the problems in alot of companies; they are going to get a "young engineer" to do the job! What you'll end up with is a "cheap engineer" doing a half-a$$ job. The old adage of "you get what you pay for" still applies in today's world.

I agree, I worked for one of those companies that gave it to the new guy...it was overwhelming, and I'm sure a lot slipped through the cracks.

Now, ten years later, I like to do my own reviews...in my industry, the battle is won and lost in the specifications.

But how do the young engineers ever learn how to do it if all the older engineers do it themselves?

We mentor our younger engineers in how to do it, (how to check model numbers, how to check ASTM numbers, etc.) and run a less time consuming back check of their work. That way the younger engineer gets trained and the company makes money because the older (more expensive) engineer didnt have to do all the work.

They get what they pay for because we give them a quality check, but don't tie up the older engineer in something a younger (and less expensive) engineer can do with proper training and oversight.

I agree with using the younger engineers for this task. It's a good way to expose them to specifications and submittals, see the importance of them and most important, ask questions! An important way for a young engineer to learn is to be exposed to project materials and get to what's crucial, what's good design touches and what's fluff. I see submittal review as a way to do this and be productive.
