In a raised floor environment, the CRACs force air under the floor, and 
then you place a perforated floor tile where you need the airflow.  In 
effect, the floor becomes your ducting system.   So yes, it is 
pressurized.  If you remove a bunch of floor tiles then you lose 
pressurization, and the air will escape using the path of least 
resistance rather than be directed to the racks or areas where the 
cooling is really needed.

I could possibly make the argument that only being able to remove a 
single floor tile at a time or having to have the building manager 
present is overkill or speaks to an underbuilt system, but each room is 
unique.   We're fortunate to have plenty of capacity to handle 
maintenance in our raised floor facility.  But it's certainly a lot 
easier and faster to work in our overhead rooms.  And truth be told, the 
raised floor room doesn't save us a nickel on cooling.  But some folks 
just need to see that raised floor.
