I’m wondering how others have incoming building power.

I’m both the facilities and datacenter manager.

You have asked a question that is going to be much larger than your question implies that you have in mind.
.
However, let’s start with the Data Center…
Do you have a budget for the move? specifically, the data center portion?
Do you have, or are you planning on UPS capability?
If you already have UPSs, are they individual system sized, or larger such as Liebert?
If smaller, make sure that you know the actual loads of each UPS (with servers running), and that you allow enough circuits so that no one circuit exceeds 80% of the rated load – That’s NEC (National Electrical Code) for full-time loads – which most data centers are. Personally, I’d recommend that you plan for about 30-40% capacity on each circuit to leave room for expansion.
.
For cooling, you need to translate the maximum wattage load of your data center (servers, consoles, network equipment, UPS inefficiency, lighting, etc.) into BTUs. To do this multiply the number of Kilowatts pulled at the maximum load by 56.84. Once you have the BTUs, then an HVAC (Heating, Ventilating, Air Conditioning) contractor can convert that into “tons” for calculating the cooling load.
.
I’ve simplified a number of things here, but hopefully set you on the right track.
.
The key thing here is that you need someone who knows facilities, data centers, and project management. That may or may not be the same person. This is NOT a trivial project.
