i reckon after concrete has topped out at lev155, the rest of the tower will catch up so that all concrete is done.
Then the next half a dozen floors which are steel frame concrete floor will be next phase which will reach lev162 or 624m high. It may stay at this height for a while. so it will be just under tallest structure for a tease.
Then the next 4 tiers are each 19m high and consist of 3x 6m high levels will be erected, which will reach tier22 or 701m. This is highest main roof.
then onto 2 more 19m high tiers (23 & 24) reaching tier 24 or 739m.
Then 3x 10m high tiers which all have 3m high levels topping out at tier27/768m.
I also think the pinnacle will be constructed in these levels and hoisted up in sections to telescope to 818m or thereabouts. my theory.lol
Above lev155 or top of concrete section, the steel section will rise 232 more metres. or equvilent to adding park Place on top!
