My drawing notes show 'symbols' for Existing Elevation, New Elevation, and Invert Elevations... I would have something similar to x NNN for existing and x [NNN+6"] where 'x' is the location and NNN is the actual value for the elevation. The former is the existing elevation at grade or maybe new elevation at grade (latter)and the latter would be the elevation of the top of slab.
For example if existing grade was 107'-9" and the new grade was 110'-0" and the top of slab was 110'-6", they would be denoted
x 107'-9", x [110'-0"], and x [110'-6"], respectively.
Maybe I should be a little more specific. Showing it on a drawing is not a problem - I can just dimension it in a detail. In the attached sketch, what I am referring to is the '6" MIN.'
The problem is, if I want to discuss this thing, I have no word for it, but I end up describing it. It seems like there should be a word.
All of the code references that I'm seeing are along the lines of "Equipment must be X inches above adjoining ground level" rather than "The Y must be X inches" where Y is whatever word I was hoping to be the official term that describes the portion of the pad above grade.
I'll try giving "projecting" a whirl and see how it goes. I like "raised" in most cases, but if you had an existing pad that projects say 2" and you wanted to add a little 4" housekeeping pad to bring the projection to 6", using the term "raised" to describe the 6" could be confusing (because it is being raised 4" so that it is "raised" 6" total.)
