Assuming you can run cable to an existing telco room and it has room on a patch panel for expansion, you really only need the Cat6 to be pulled and terminated to plug in a POE AP. Ideally, having 20% overlap for the AP signal. So, depending on the plans you should be able to figure requirement for a count and placement.
If you cannot pull to a existing telco room, you most likely need to build a new telco room and have fiber pulled to where the core is located. This would need rack, patch panel, patch cables, POE switch(es) (most likely need configuration too), UPS (uniterrupted power supply), and power.
In general you can never have too many network drops. There are other cost such as conduit and hardware, but I would bet there are already in the plans. This is just off the top of my head and if I think of more I will post back.
