It looks like the yellow posts holding up the corner section have been removed from all but the south-west corner. Yet, no signs of them pouring the corner floor slabs that've been ready for months now.
interesting i wonder if the next level corner pour is about to happen, maybe they wanted full tension weight on before pouring?
they have several floors above to create tension... but also the corners should cancel out some of the pulling force since the corner floors will be under compression from the pulling force of the tension members.Maybe they have to wait for the floor where the upper attachment point is to completely cure first so that the tension from the added weight at the corner won't pull the columns outwards?
I'm surprised they're not using fly forms for the main faces yet. Looks like they wouldn't work on the corners, but surely would save some time on the spaces between the super columns?
