Network design (rack, ethernet, cctv) for new building (fire department in Europe)

Hello

I want to submit requirements from the networking/it perspective to the architect. Even if the architect does it on his own, I want to at least compare my requirements against what they suggest.

We currently have 3 pcs + 2 infoscreens which need internet over ethernet access. A lot of people work on mobile devices (may be their own). My main aspect is future proofing (at least the ducting has to be installed).

What I've got so far: * central 42U Rack in a dry/dust free room. Will probably only emitt 500W of heat. (patchpanel, switches, router+modem, qnap nas, dokuwiki server, phone system, speaker system for the building, ups) * cat7a, >=1000mhz ethernet cables, might be used for poe, maybe also for security cameras * wifi for the complete building, dual ethernet cables per drop (probably ubiquiti, guest and internal ssid) * cables/or at least ducting for security cameras on the outside, parking lot, entries and hallway (terminates at the server rack) * double ethernet drop to every potential workplace * double ethernet drop to every room (minimum, more if room is larger * power and ethernet socket in the floor of our main assembly room (we do meetings here, will fit up to 60 people) * cables for a central phone system, controller should be in the rack * preparation for home automation and electrical lock system (at least one cable to every door and vehicle gate)

I need to get the requirements correct at the beginning, installing cables afterwards is possible but requires the ducting, which has to be installed in the building phase.

Are there any guidelines on how to calculate the required required distribution of ethernet drops (or at least empty ducting)? Am I missing something obvious?
