Here is a very understandable engineering discussion of the construction of the Millenium Tower. Fascinating and elucidating of what is involved. The building had already sunk 16 inches by 2016 when the public first learned about it. Many other projects are also using water drawdown wells in the area (common practice as described in the video).

Wow. Fascinating link! Thanks for posting it!
Can’t believe nobody considered the retrofit might accelerate settling...
