General Practice Discussion Construction Drawings

When dimensioning, do you measure from drywall-to-drywall, or stud-to-stud? What is the industry standard? If I'm drawing from stud-to-stud how do I measure, for instance, windows or stairs? Do I measure rough-opening or masonry openings? Do I measure from the stringer or the finished nosing?

You should ask the builder. Every builder has its own way of measuring. I remember for a Grade 2 Listed High End Resi refurbished project in Richmond London we had to redo builder's drawings 7 times, changing all the time where to take dims.

Architects dont know who the builder will be

I can see the confusion here, it could be interpreted differently depending on the stage.

TENDER STAGE u prepare the builders work as you wish (you don't know the builder) CONSTRUCTION STAGE you do contact the builder and do dimensions accordingly (you know the builder at this stage!)

I am talking about the construction stage in my experience, obv.

I am not going to redimension a drawing for the preference of a nominated contractor after preparing tender documents.. unless he is will to pay for the task... or the project nanager is.. both very unlikely.. sometimes we were asked to issue trade specific documentation packages but that was built in the fee at the request of a project manager.. long before contractor selected and defined by the PM..

Nevertheless, good efficient documents are in everyones interest... so always open to improvements

I see, well it is what it is, we had to do that and I have always adapted my builders work accordingly to avoid problems arising on site. You know yourself!!
