Well it's not to ASME Y14.5M-1994 by the looks of it. What industry though?

Quezon50, I'd says it is standard, but do not claim it meets a standard.

To write 1' when 1'-0" is meant is ambigious and confusing.

I generally dimension in ft-in on large welded assemblies because the welders use tape measures graduated in, yes, feet and inches.

Looks pretty "standard" for architectural drafting.

Have you read faq731-376 to make the best use of these Forums?
 
I have nothing solid to base this on in terms of formal standards, but have seen any dimension less than 2'-0" expressed only in inches (23", 17 1/2", etc) and use the foot indicator for 2'-0" and greater. Not sure if that's the feedback you are looking for.
 
It depends on the accuracy you need. To state 9' means it can be between 8.50' and 9.49'. To state 1'-0” means it can be between 0'-11.5” and 1'-0.49”. etc.

As EOR's we should take the responsibility to design our structures to support the components we allow in our design per that industry standards.
 
Says' who? Where on earth did anyone specify a +-.5 tolerance?

Trying to use common rounding conventions seems questionable.

KENAT - If you do not want to use the common rounding conventions then you need to specify the allowable tolerance you need. If you do not specify the allowable tolerance needed or want to have used the common rounding convention, then what it the allowable tolerance to be used?

The information given by the OP is completely out of context, in some contexts you don't get to simply assume rounding.
