height floorplate to floorplate

The median height between the tops of two adjacent floorplates in a multistory structure.

The floorplate-to-flloorplate (floor-to-floor) height is the median interval between the top of one floorplate and the top of the next successive floorplate.

If a building has an even number of irregularly spaced floors and a median cannot be obtained, then the average of the two measurements in the middle of the range is used. Any floorplate of variable height should be assigned its median level.
