if you drive the piles to bedrock, which if
Memory serves should be about 45 feet, there should be no problem...

IIRC this building uses ‘friction pilings’, NOT END BEARING.

Bad idea?

And do not forget that an adjacent building did some deep excavation very near the leaning tower.

You refresh my memory... it was friction pilings. It’s pretty much muck down to bredrock in that area, so I’d say they chose poorly though, obviously, this was an approved design

Some corrections: the Friction piles go down 60-90 feet through the bay
Mud to a compacted sand formation. Bedrock is at 200 feet. Sorry for the faulty recollection before
