consider and plan, and some of it needs expert input if only for reasons
of compliance. (I know, we built two new ones in the last two years).
As for knowing how much heat is generated and power consumed, reality
bears no resemblance to manufacturers' data. Sadly, that matters a lot
(because of costs of power infrastructure and cooling provision) when
dealing with budget holders and accountants.

knowledge. You know how much heat the computers generate and how
much power they eat, etc.
There are other considerations. For cooling, you have to take into
account airflow and hot spots (which are not always easy to predict!),
and vent tile type and placement (if raised flooring is in use). For
power, there's distribution patterns, phase and branch balancing,
headroom, start surge considerations and sequencing, and grounding. And
don't forget floor loading considerations. And fire control. And
cableways in and out of the room.
