The tower itself will have lift/stairs inside the main column with a glass lift on the outside (nice!) At the base will be a small 2/3 story office building for ops/training etc.. No rest rooms for night shifts (tut tut) or food facilities, plus a 25min walk from T3 to get there.
No details wrt escaping in fire. I'm sure they have solved such a problem and will let us know the procedures before we get up there (yeah right!)
The penultimate section was put in place on night of 21/02, the last section was transported across to the base on night of 22/02. Should be in place by the weekend.
Building should be complete by the end of the year. Will be operational by Oct next year (place your bets now!)
Cheers!
