Lighting, cinema, cameras, and door stations all depend on a network that was drawn before the ceilings closed. Once the plaster is on, a missing cable becomes a compromise.
We start with where people sit, where equipment lives, and which rooms need a wired connection rather than a guess at Wi-Fi. Racks, switches, and access points are placed so coverage is even and the cabinet stays serviceable.
A clear cable schedule also keeps the later trades honest. The electrician, the joiner, and the integrator are working from the same drawing, not from a list of products.
