Technical drawing reviewing too time consuming?
Technical drawing reviewing too time consuming?
(OP)
I'm a junior structural engineer with 1.5 years of experience, based in Germany. In my office, we each have to review multiple shop drawings of concrete components every week. The process often feels repetitive and, honestly, a bit demeaning boring, as it mostly involves checking that all components are correctly inserted, referenced, and specified.
Does anyone else find themselves in a similar situation?
Are there any software solutions to help automate or streamline this process? We currently use Bluebeam, but it still feels quite manual.

RE: Technical drawing reviewing too time consuming?
You post is vague and incomplete. Please clarify. What kind of drawings are you being asked to review? Structural design drawings or shop drawings? Also, what kind of structures are you designing? Steel? Concrete? Wood? How many years experience do you have? Also, are you in the U.S.?

@RPGs: I find it kinda demeaning because it feels like a monotonous, low-skill task that doesn’t really utilize any of my (engineering) knowledge. While I understand that accuracy and attention to detail are important, this task mainly involves checking that all components are properly referenced and inserted in the drawings, rather than engaging in design or analysis.
RE: Technical drawing reviewing too time consuming?
Some people have more tolerance for these types of tasks. Maybe that's not you. LOL. It's not me, either, BTW. If I found myself stuck doing that long term, I would be looking for ways out. I know people who have spent much of their lives checking shop drawings. I don't know what mental tricks they have for staying the game and continuing to look for errors, and not going crazy.
RE: Technical drawing reviewing too time consuming?
Like 271828, I've met engineers that are OK with that and have no desire to do much else, but if you aren't OK with that it might be time to look at your options. If you like your firm, at a minimum it's time to talk to your supervisor and see if there's a path out of the shop drawing review sweat shop. If you can't get an answer that aligns with your career goals, it may be time to change firms.
I don't know what the job market looks like in Germany, but here in the US, small to mid-size firms seem to have what you're looking for.
I have only worked at small firms and it has been ideal in giving me a wide variety of project experience. I've had my fair share of mind-numbing shop drawing reviews (and there will certainly be many more in my future--it tends to come with the territory), but they are relatively few and far between and sometimes I actually appreciate them as a break from projects that are excruciating design/analysis headaches.
Navigating the structural engineering industry is very challenging, but at a minimum you can take heart that you are doing important work. Best wishes to you.
RE: Technical drawing reviewing too time consuming?
Demeaning!? How is doing extremely important work demeaning? Do you think you are better/more important than the rest of the people around you? There is plenty of unexciting and undesirable work in all careers and professions. Do you really think a medical doctor is enthusiastic about performing a prostate examination? Lawyers still need to read 100s or 1000s of pages of boring contracts in order to do their due diligence. When you are more senior sometimes you can outsource a large majority of the more mundane tasks to more junior staff, but it never completely disappears.
I am the most senior engineer in the company I work for and I also do work for myself. Yet I also have to review shop drawings at times.
Sure review drawings isn't exciting but if you find it demeaning you either don't understand the meaning of the English word or you have an inflated sense of self importance.
(And with respect to you, maybe you chose the wrong word which is totally understandable as presumably English isn't your primary language.)
RE: Technical drawing reviewing too time consuming?
Reviewing shop drawings is extremely important. The purpose of shop drawing review is primarily to check that the detailers correctly interpreted your drawings and properly detailed the reinforcing steel and whatever other embeds are in the concrete. But the shop drawing review is also the last chance to catch mistakes on the design drawings. While young engineers are often responsible for reviewing shop drawings, I sometimes joke that shop review should be performed by the most experienced engineers – because this is the last chance to find a major mistake! People have died because of mistakes made by structural engineers and failure to catch those mistakes during shop drawing review. Likewise subtle changes could have been made by the detailer that could result in a failure (Google “Kansas City Hyatt Regency skywalk collapse”. 114 people dead.) There were many reasons that led to that collapse – not just a shop drawing error. If you don’t review the shop drawings, who in your office would review them? The drawings must be reviewed by some who knows what they are looking at.
When reviewing shop drawings, you are not just looking at what is on the drawings. You also have to look for what is missing from the drawings. This is often the hardest part – and it is something that cannot be done by engineers with little experience.
To my knowledge there are no software solutions that will facilitate shop drawing review. When the manufacturers of structural engineering software start making claims that their product uses Artificial Intelligence to save time – BE CAREFUL!!! That will be an exaggeration. A human brain will always (for at least the next 30 years) be required to thoroughly review shop drawings! And for us, that’s a good thing. Otherwise, we could be replaced by robots!
Reviewing shop drawings is NOT demeaning!
I agree with human909. I suspect the English word "demeaning" is not the exact word you were looking for. "Boring" might better describe shop drawing review. That is, until you find a huge mistake that might have slipped by were it not for you being knowledgeable and alert, catching it, and avoiding a major problem!

RE: Technical drawing reviewing too time consuming?
I agree that "demeaning" was a strong or misleading word. I’ve replaced it with "boring," which better describes what I meant.
@cliff234 — Since you mentioned Artificial Intelligence, have you had any negative experiences with AI tools for this task? I imagine that while AI might not fully automate the process, but it could help streamline part of it?
@hokie66 @human909 @cliff234 — I completely agree; this is an important task, and I’m not questioning its value. I was curious to hear if others were in similar situations or if they’ve found better processes or (automation) tools to make it less repetitive.
@RPGs @271828 — You’re right! Exploring a change, whether it’s improving things internally or finding a new opportunity, might be something to consider down the line.
RE: Technical drawing reviewing too time consuming?
Engineering could be described the same way, but less extreme (not so much "sheer terror" as "people losing their heads and blaming it on you", so project schedules and budgets disappear, along with the unicorns and fairy princesses).
If the job you're in isn't satisfying (and I've had my share) then change it.
Are you checking just the drafting, important but depressingly dull, or are you also checking compliance to code ?
What can you learn by reviewing drawings (hint, not nothing)?

RE: Technical drawing reviewing too time consuming?
I find what's helped me the most when reviewing these is I start with the mindset that there IS a mistake and I have to find it. This puts me in a more engaged headspace rather than passively scrolling and lulling myself into saying it's okay.
More often than not, there is a mistake, and that feeling of finding it is very rewarding.
RE: Technical drawing reviewing too time consuming?
While it's important to make clear that your review is only for general conformance with the structural design (or whatever the current recommended wording is from a liability standpoint), I still like to review shop drawings in a rather high level of detail.
I generally don't find the task as terrible as others above, mainly because it is very important. Generally it's good practice to start with a checklist and then meticulously go through the drawings, checking as you go. For more critical items, look closer at those areas. Like the comment above noted, I try to make it a game to see how quickly I can find an error. That seems to make the boredom a little less.
You will be amazed at the errors you find as soon as you start to look close. I can't recall a single time I failed to find something of significance on a shop drawing review. Often I find significant errors! Concerning concrete in particular, on a project several years ago, I noticed that a number of prefab. concrete panels would be fabricated with the inner/outer sides reversed based on the shop drawings. I pointed this out, and yet, somehow, they still were still fabricated incorrectly and then installed backwards! Things still got messed up in this case, but I had the receipts in hand before anybody could even think about trying to pass the blame onto us.
RE: Technical drawing reviewing too time consuming?
There are limitations with ALL structural engineering software. The challenge is for engineer to know and understand those limitations.
Having an understanding of constructability, connection design and detailing, and software limitations is extremely important for all engineers – and to my knowledge those things are not taught in college (with the exception that general graduate level courses in connection design are offered at most universities). Connection design is equal parts art and science. While the “science” part of connection design may be taught in school, the “art” part is learned on the job – hence the absolute necessity of having all designs performed by engineers (especially young ones) reviewed by experienced engineers.
RE: Technical drawing reviewing too time consuming?
The latest one, a few months ago, was the moment connection of a beam to an HSS column for a moment in excess of the column capacity. I don't raise any flags... just ask for confirmation (for liability reasons).

RE: Technical drawing reviewing too time consuming?
However, like you, I hated reviewing shop drawings as a young engineer.
More than a decade in, I find it more enjoyable, the addition of a 3D model on the shopdrawing package helped alot.
Can't put enough emphasis how important the process is. Good example is the shopdrawings I reviewed a few days ago. Detailer changed the roof beam pitch due to presence of a box gutter. It seriously affected roof connections, purlin connections, bracings, etc. Our clearance was short by 50mm and it made all the difference for the construction of the box gutter (Architects and their box gutters, yeah?).
It gave the Architect and myself a chance to resolve this before it was fabricated. It would have been a nightmare to repair this on site.
RE: Technical drawing reviewing too time consuming?
Just out of curiosity, What structural engineering software have you used that you consider to be "AI"? I have not seen any that I would label in that manner. Or perhaps I misunderstood your statement?
RE: Technical drawing reviewing too time consuming?
RE: Technical drawing reviewing too time consuming?
How do you write computer code to address and solve the many unique constructability problems that can occur in building structures? It’s challenging enough “programing” (i.e., training) human engineers to find and solve constructability issues!
RE: Technical drawing reviewing too time consuming?
Okey, I understand, you have your own definition of "AI". That explains it . By that definition I think any software can be considered "AI" since software usually has the purpose of simplifying somebodys work.
But I will continue to use more common definitions of "AI". An early approach was the Turing test, I don't know any structural software that would pass that test.
RE: Technical drawing reviewing too time consuming?
Definitely, the Turing test is a big challenge indeed. But don't you think that these new AIs (ChatGPT-level) could maybe be able to do part of the drawing review, for example checking that all components are (correctly) inserted, referenced, and specified in the drawing?
RE: Technical drawing reviewing too time consuming?
On an somewhat related note, the same is true of drafting. Engineers who do their own drafting instead of farming this work to actual drafters are using up time that could bill at a higher rate to perform work that can done more cost effectively and in most cases better by a drafter. There is a saying, "when you let engineers do drafting, you get lesser quality drawings that you paid too much for."
RE: Technical drawing reviewing too time consuming?
Likewise some constructability problems might be easily solvable if the problematic condition (usually a connection) is properly designed and detailed. But in the U.S., how often do design models contain all the connection details? (Answer: Very rarely)

RE: Technical drawing reviewing too time consuming?
I think that AI may in the future be able to assist with things like that. One challenge will probably be how to describe the task to a computer. I think that is the main thing with AI. To be able to communicate with a computer as you do with a human. That is also what the Turing test is about.
But I think it will be some time before "Checked with AI" will be considered as a guarantee of quality.
RE: Technical drawing reviewing too time consuming?
As basically a one-man show, I do my own drafting and for the relatively small jobs aI do ($10k USD or less typically), this works better for me and the customer. I have been drafting my work since about 1995 and I can go toe to toe with most dedicated draftsman. I also engineer the plans as I draft them so my "feel" of the job is better than if I delegated it. And, there is no time lost trying to communicate my ideas to the draftsman and then checking their work.
RE: Technical drawing reviewing too time consuming?
Meanwhile, structural analysis/design was emphasized in school and this is where you feel your interest, expertise, and best opportunity to contribute lies - rightly so. Trouble is, you're not in the structural analysis/design business! You're in the Development-Architecture-MEP Engineering-Structural Engineering-Construction-Real Estate Sales Business, of which shop drawing review is a part. After 30 yrs, though less than I once did, I'm still looking at shop drawings.
One more thing, all of the seniors at your office have been through the same thing you're going through - they're observing how you handle it. Don't blow it off - you don't want one of those mistakes, mentioned in other responses, to get by you. Case Studies are full of failures that could have been prevented in the shop drawing stage.
RE: Technical drawing reviewing too time consuming?
My first few years were spent on construction administration for commercial building projects. This was in the '00s, on the cusp of Bluebeam - but not quite.
On one large, very multi-story steel project, each steel piece drawing was printed on ARCH E sheets (36 in x 48 in) - SIZE E! Every W10x12 infill around a floor penetration - 36x48. Three copies. Etc.
Each piece had to be reviewed, and all the comments made on one sheet had to be manually written over to two others copies, each page stamped with a review stamp - and folded (FOLDED) and FedEx'd back to the team. The act of folding several thousand sheets caused my finger prints to, ahem, smooth-i-fy. Which wasn't a good look (nor was it comfortable). Borderline demeaning, even.
But man, did I get a feel for how structural systems come together. And man, did I stumble upon a series of potential errors along the way. Why? I was just another set of eyes on the drawings, double checking, and allowing my intuition (which was still developing) sniff out things that didn't feel right. That helped build that intuition over time. It helped me be able to, eventually, design, depict, and review a structural system.
I mean even this summer, I reviewed shops on a small steel frame that I designed to support a small thing. My drawings were good, but, when I saw how the pieces were coming together from the detailer -- it, just, didn't feel right. Catching it there allowed me to make an easy tweak, which was no big deal, and it came together nicely. Thank you, shop drawing review.
So as an engineer with 1.5 years of experience, one of the best things that you could do is construction administration for projects. That's my two cents. Plus, with Bluebeam, the risk of loosing your finger prints is minimal.
Grow that intuition, where you are, while you can.

RE: Technical drawing reviewing too time consuming?
Of all the projects I've worked on which went poorly during construction, the big problems were almost entirely related to aspects of the construction which didn't rely on the shop drawing review process. For this reason, it seems steel building elements rarely have major problems. Field framing, on the other had, often does due to the missing level of oversight.
Shop drawings provide a nice preview of what's about to be done. If some of these carpenters had to create shop drawings for what they were planning to do, we'd definitely be shaking our heads and catching major problems before they happen.
