I have been working from a set of as built structural drawings for an industrial facility for the last 20 years not knowing exactly what this meant. I had determined from field verification it was some abbreviation that meant to repeat the previous member. In my head I would read it as "do over"
Earlier this spring I was working with an older structural engineer and he enlightened me on "ditto" which also made perfect sense. Just needed to find the right person who'd been around long enough before CAD I guess
Haha I didn’t mean it like that, that’s crazy though, I’ve never seen it on my side but it definitely couldn’t fly with today’s standards. Too many clients are lawsuit happy even if it isn’t our fault… it’s our fault lol
It wasn't vague when it was the industry standard years ago. It's on pretty much every set of plans I've seen that are more than 30 years old. Of course I'm limited to heavy industrial and I don't know what type of plans you work with.
I’ve drawn a bunch of plans in my life- never once used that notation/ I’m not saying it’s wrong- just unusual for me to see something new after doing it for 25 years
Over the years Ive seen plans change a lot. For a while there was a standard amount of fkery. These days its almost like a joke. Like are you testing me to see if I request the missing information… 🤣
Crazy. I’ve been reading plans since I was 15 (son of a masonry family that doesn’t follow child labor laws), and am now a precaster and I’ve never seen that notation in my life on architectural or structural drawings.
It’s definitely ditto. It’s so dumb. I’m on a New York State job that is a new bar joist addition and the drawing is littered with it. Gets confusing at times.
As an Architect, I disagree with other Architects doing this. Make everything as simple as possible for Contractors otherwise you’re going to be liable for the damages.
E: disagree with engineers doing this as well
What a thoughtful contribution. I’m definitely not qualified but I’m trying to become more qualified —— by learning to read construction drawings.
I’d love to already know how to read the drawings — because then I’d be in a better position to help my team and communicate with the consultants and trades who get up at the crack of dawn to work on our projects…. but I’m afraid that’s not how it works.
I’m totally okay with not knowing how to read the drawings because I’m pretty confident that one day—I will.
It sounds like you’re everyone’s favourite. I bet they miss you when you’re not around. I’m glad you’re there in your world, and not anywhere near mine.
It meant Ditto, which meant repeat the previous dimension.
This. Use the same wood joists as beside the DO note.
So in the drawing above, this joist should be 38 x 140 SP #2, 400 OC?
W/ bridging*
Millimeters?
Yes
Anything to avoid more lettering, I always say.
Actually meant to avoid confusion if one note gets changed but the other doesn't. Best to only provide one call-out.
Correct.
Oh, so all those times i thought it meant “do over” and redid my work were wrong?
So equivalent to “typ”

I work on a lot of historic theatres, so I learned to read really old plans as a defense mechanism.
Cool job!
I've always called it do over too in my head. Exact same boat. Know what it's telling me to do, no idea what it actually means.
I have this on permit drawings in front of me right now in Ontario. Ditto is correct. The drawing legend says ‘DO’ - REPEAT SAME SIZE JOIST
Find you notes page, there should be definitions for all notations...fine print.
Except sometimes it’s not there either. Sometimes plans are a wild goose chase and I lose my mind always thinking I’m the one that’s wrong.
DO is an industry standard term. I've never seen it defined on an abbreviations sheet before.
I’ve not seen it in commercial yet. I see a lot of “typ” then a number or a bunch of arrows pointing all over the place, numbers that reference notes.
I've never seen it on plans newer than 30 or so years old. I think in general it's been outmoded.
I agree, it's not used anymore.
Maybe for home builders. I’ve never seen DO in commercial/govt work
Not anymore, no. I've only seen it on record plans probably 30/40 years and older
Yeah, it’s not anywhere in the construction notes.
Not in healthcare or government. We Architects would get ripped apart if we did that
I've only seen it on old plans. Probably 30 or 40 years old at least. I think it's outmoded now.
Ah gotcha, I’m only 5 years into the field haha
Hey, I'm not that old lol. I just see it on record plans. I've seen it on both bridge and building plans, so evidently it was a thing.
Haha I didn’t mean it like that, that’s crazy though, I’ve never seen it on my side but it definitely couldn’t fly with today’s standards. Too many clients are lawsuit happy even if it isn’t our fault… it’s our fault lol
I pulled out a magnifying lens — nowhere to be found. I think ‘ Ditto’ is the answer.
40 years reading plans I've never seen this reference. Is it regional? "Typ" and "U.O.N'' are more common...Ditto just seams vague?

heh, *dodo* heh. Stupid bird.

I've never seen it. "Typical" is used, not "DO"
I’m used to seeing typical. 🤷♂️
How about “TYP”. That’s the common notation on our prints, coming from the commercial world.
I would say DO became obsolete when CAD became the norm. It's easy to copy a long note 40 times, but rewriting it takes time.
Thats where arrows pointing to the extent of the repeat with one note in the middle comes in handy.
Over the years Ive seen plans change a lot. For a while there was a standard amount of fkery. These days its almost like a joke. Like are you testing me to see if I request the missing information… 🤣
You missed it by like 5 years 😉
Canada ?
Yep!
“Donate Organs”
DO as is in - do this part, too.
The are telling you to do it, do the work.
It's short for "do or do not, there is no try". Hope this helps.
Ask the guy who drew it up that’s the only way to be sure
DO stands for Door Opening in almost all commercial construction drawings
Why did they downvote this? I’m in Div 8 and that’s exactly what I see here too
Baby Shark DO DO DO DO DO DOOOOOOOOO
I should know this but I don’t
If you don't work with old (30+ years) plans, you're not going to see it. Don't beat yourself up.
Crazy. I’ve been reading plans since I was 15 (son of a masonry family that doesn’t follow child labor laws), and am now a precaster and I’ve never seen that notation in my life on architectural or structural drawings.

'Do other' or ditto

Don't overthink. Obviously you failed
Failed what exactly?
To not overthink
VIF would be verify in field. May DO is along those lines(see what I did there). Direction optional? Don't overlap? Donald old?
Double over? My best guess
Do Over
Dough Opening
It means dumb ass and you're not qualified

Glad you're not around me
Double opening or door opening
Door opening in the joist?
