I’ve worked on projects where a lot of work was done in highly collaborative drawings on Bluebeam, in which vendors add their markups and items and the program facilitates counting it all at the end of the phase. My role was only in things like wireless AP placement and low voltage cabling drop locations, not anything safety critical like doors, but I assume those vendors were able to keep track of those items in a similar way. For actual engineering projects I’m glad so many people have to take the time to count.
