Controlling contractor focus with PDF tagging

Hello. I am A hybrid bim manager and all kinds of thing at a medium size gc.
When I divide a plan to sections, the contractor gets lost in too many plans.
When there is one big plan I can’t tell what they are looking at.
I would like to stick a QR code next to every room. and use geo spatical coordinates(I think. any workflow that you can think of) to mark location. upload locations and plans to our nextcloud server & link them to the aligning QR codes.
Any input would be great. Thank you.
