Absolutely for lateral loads and structural rigidity. State of the art for a tall skinny residential building. St. Regis in Chicago had a similar amount of concrete walls across the three masses for the same reason. And still required a blow-thru floor to minimize sway.That's a lot of structure and weight if solid walls and true proportions. Thanks Chester for digging up the engineering drawings, it provides some explanation of the massive reinforcement we're seeing in the podium.
Edit: I'm interested to see if they pour all the vertical elements at once as per the last floor. That might suggest other things at play such and structural rigidity and lateral load transfer. Never seen anything go up like this.
