For the wall legends the underpinning data needs to be the basis for tagging- and from best accounts in my research and discussions with other BIM Managers- modular systems seem the best way to go.
One possible combination a wall class (Existing, Concrete, Masonry, H=Shaft, S=Steel Stud, W=wood) +
(Nominal size of the wall assembly rounded to the nearest quarter i.e. 4 for four inches,
More definitive would be eights expressed as 1 2 3 4 5 6 7 8 so 4-1/2" would be 42, 7-5/8" would be 75. This could be brought back to 1/4" increments- and should be noted in the schedule general notes.
Additionally for more interior-intense finish jobs I have seen systems similar to above over a
list of modifiers for interior-exterior in a compound tag.
The finishes won't be of particular note to the wall tags- Unless there is a specific UL that calls it out or requires it... Or if a specific assembly is required for structural support as in the stone.
A schedule of wall types should also be generated and left on the sheet just as the VA indicated on their sheets. Note also the VA Doesn't appear to have a graphic wall legend. Instead we could utilize the schedule and general details which would save a lot of space and follow the current trend Tony seems to be headed for.
DOOR AND WINDOW SCHEDULES
Ideally the head/jamb/sills are called out in the schedules-
Callouts cannot go in legend views. Callouts can go into drafting views. So a drafting view of a typical window with 'width see schedule' and 'height see schedule' should cover most types.
Dummy tags or text typically gets overlooked. General notes or schedules would be preferred over the dummy tags is possible- with the callouts being the most ideal.
Shortly before each critical printing the schedules and the partition types should be looked over.
