Yeah exactly, Phase 2 needs to redirect the same amount of weight into a notably smaller foundation, due to the rail corridor. Plus there's the whole thing where the tower itself is essentially cantilevered over said active rail corridor, which as someone who was originally a civil engineering grad, a level of complexity that makes my brain hurt just to think about. This is up there with The One in terms of complex structural engineering projects in Toronto rn.I've always maintained that the complexity of the base of Phase 2 is and was radically different to Phase 1 here. Being that, Phase 1 was fairly straight forward conventional build; where as, Phase 2 was built unconventionally on a pivot of sorts which required a lot more engineering gymnastics to make it work. I mean, the podiums weight of the tower goes straight into the core with the latter, opposed to using common supports for weight distribution for the respective tower with the former. Therefore, making Phase 2 take much longer to build at least at podium level...if that makes any sense.
