Several of the medical centres we have helped, brought us in when the builder had aready started the 2nd fix, and this is typical in many signage installations we do ... and then asked us what signage they needed ...
the signage was an after thought.
This meant that some types of signage such as illuminated signs, back lit letters and LED displays, ended up costing far more than necessary.
External and interior signage needs to be included and designed into the build from the start.
Signage must be a forethought!
Signage decisions are best done with the owner, architect, builder, medical interior designer, and signwriter working together from the beginning. This applies to both brand new builds, and conversions of existing premises.
