I have only seen them on the symbols legend on the Contract Drawings as you stated they are not symboled by AWS or AISC.
http://www.fciol.com/documents/joint_forcesWY/add_2dwgs/FMS04-STRUCTURAL.pdf is a pdf showing a symbols legend, from there the detailer needs to be aware of the different ways of accomplishing the moment connection and if it is acceptable to the EOR
It is up to the Engineer of Record to decide the type of moment connection or have the contractor engineer them and detail. Sometimes they will show a couple of options,(bolted/welded)
But I have never seen them listed as such.
They are in most of the Drafting programs, Autodesk...
How is the employee search coming?
Good Luck
