From what I'm finding, they are still doing core work on 5 WTC? It sounds like, anyway. They may not be as far along with the core as they are for 2 WTC (the one that is past street level right now, if I'm thinking of the right building).
As for glass work on 1 WTC, yes, Alan had said 4/16 was the approximate day they would start again. At any rate, I hope it starts again this week - I really miss watching the glass rise!
