Caissons bear directly on the bedrock surface. So the length is irrelevant.
They could have below grade levels or not, the extra length of pile at the top can just be trimmed down.
The fact they are load testing caissons is curious. Obviously they work, simply looking at the number of highrises around it that have a similar foundation.
I guess they must really be trying to finesse the foundation design to get as few piles as necessary. Being a structural engineer, I am not a big fan of foundation finesse.
