OBS:
Since OFP, building positions (buildingPos) have all been accessible from ground level outside the building.
In Apex, there are several buildings that have inaccessible building positions, such as on the roof of a multistory building with no stair or ladder access.

EXP:
Building positions should be accessible from ground level, to both player and AI.
Alternatively, provide some method of defining these building positions as inaccessible, to script and AI units.
