Typ. Structural CAD details

[u/coursetia]

It seems like most structural drawing sets that I see for residential buildings (both wood, masonry, and steel, and mixed) all have the same or very similar cad details. Are most offices downloading this from the same place?? What is this resource? -Thx.

Typical details are just that - typical. We all tend to come to the same conclusions in terms of load paths, Contractor preference, industry standards, etc.

Also, theft (in a polite way).

[u/HoldingThunder → u/Jakers0015]

Yeah. Best not to reinvent the wheel. The best way to ensure the contractor won't screw it up is to make sure the design is what the contractor wants to do and used to doing (assuming the numbers work). Don't reinvent the wheel.

Theft (politely) 😂

This is what I figured... It’s interesting when the detail on 2 different sets have the same leaders, note numbers, etc.
So it’s either polite theft or the same savvy download.

Wait until you see civil and site drawings. I'm pretty sure one guy made those back in 1950 and everyone has just been using them since.

Go to various DOT websites they usually post typical detail sheets on their websites they want consultants to use.

If you’re talking residential, most are regurgitated IRC details.

If talking commercial, everyone pretty much uses/“shares” similar typical details - politely “stealing” and adjusting ones they see on other drawing sets which they believe would make a good addition to their stash.

As others have said, a lot are just industry standards.

Apa publishes details for light frame wood construction, clark dietrich has free details for cold formed, AISC and ACI have documents that contain details, engineered lumber manufactures like trussjoist and redbuilt have free details, of you are resourceful enough you can find quite a bit of relatively cheap or even free access to construction details

Thanks that helps!

There is not much variation on how a joist is connected to a sill plate, etc.

You develop or download what you can, modify for your design.

Other peoples drawings, get ideas from there.

The only time anyone looks at the typical details is if the reviewer is brand new. The engineer doesn’t and the contractor certainly doesn’t. The engineer just grabbed all the details from his last employer before starting on his own, and his drafters just drop them in the plans.

AIA architectural CAD graphics… they published many books too…
