from my perspective as a specialty curtain wall detailer it doesn't matter if the project docs account for the caulking joint gap or not. What's important to me is that the documents indicate where the dimensions on plans, sections, elevations, or frame schedules are to and from. On almost every project I do this is my first RFI question because rarely is this information on the docs. Trying to figure out what a dimension extension line is relating to on a 1/4" = 1-0" frame elevation is no fun...(see t1-shep's 2'-0" dim above for instance)
and, as an aside, a caulking joint is not an aesthetic feature whose size (width) can be dictated by what you want to see. The width is determined by the design criteria of the building (story drift, LL and DL deflections, etc). I can't begin to count the number of "fights" that I've had with Architects over the years because they wanted to "see" a 3/8" joint when a 3/4" joint was required. OMG, you'd think I was pulling their arm out of the socket or something
