But the speed will go up even more when they reach normal floors, between the open floors.

It is the core forming system being raised, at the top of the core you can clearly see how it separates from the openings in the core wall bellow.

I threw in basic massing models of proposed buildings, to give you an idea how the changes will affect the skyline when seen from a helicopter.

Wow, what the hell is the really freaking huge one!

Today I drew a scale diagram at the back of my math book. I did not realise how thin it was!

This looks like a tower that would be built in India.

Today they will pour the other half of the floor slab. They are already starting right now with buckets and the pumps.

The holes for entering are also missing, maybe it's a mech floor. The core is already higher than where the retail floors will come.

Saturday was busy, and so is today. The 57St half of the floor slab was poured on Saturday, and the core rose yet again.

Today, the crane swings a 3 yard concrete bucket to pour the architectural concrete for the columns and spandrels, as the street concrete pump and the concrete placing boom atop the core stand by for pouring the 56 Street half of the floor slab. Architectural concrete is for the exposed columns and spandrels, while structural concrete is used for the core and floor slabs. Meanwhile, workers stage the materials on the half of the floor that was poured Saturday for future forming of the next floor level.

No, I think it is a whole floor, since it doesn't have the openings in the wall, it seems different.




Now it can be seen more clearly that they began to build the transitional element, at each side of the big rebar of the main columns there is a small rebar to transmit the loads from the new intermediate columns, that begin two levels up.

I had a lecture today about skyscraper construction and common problems, which made me wonder what special precautions have been made to prevent this gem from swaying too much when there is a mild breeze. are both the core and the facade load bearing? Are there any other precautions made? Because, let's face it, this is a pretty unique piece of engineering.

Is there any danger of this going wrong, when it turns out that people living in the top keep feeling sick because of the swaying and that they have to undertake actions? I would really appreciate it if anybody could shine a light on this matter.
