For what it's worth, CCs77 on SSC said,
"By the way, this building is not stalled, if apparently it has not progressed much since september, that is because they are working in the cantilever. That is a pretty complex work that takes its time. It is comparable to the fundation of the building, you don't see a lot of progress, but there is. In this case is almost as they are building the fundations of the building a hundred meters above the street. It is a complex part of the building that will support 80 stories above it."
I hope he's correct and this building continues to rise to completion!
