In other parts of the world, far taller buildings are constructed using friction piles[1].
Again, friction piles are not unusual at all. Drilling into bedrock happens in parts of Manhattan[2] , but that's because the bedrock is generally close to the surface.
Whatever's going on with Millennium Tower, it's not "friction piles bad".

Is it normal for the size of the building + use of concrete over steel (increased load)?
