No. The reason it's tallest portion has to be on the north side of the site is because that is where the core will be because there's no rail there to build over and the core can be on the ground.

The reason why Tower A (30 Hudson Yards) is steel is mainly because the shear walls of a concrete core could not have gone all the way down to the ground/foundation level due to the LIRR tracks, and also because of the particular implantation of the columns between the tracks.

The foundations and steel columns positions were dictated by the "available" spots between the tracks (with steel mega-trusses spanning over the tracks with a diaphragm at the platform level) which are different from their "final position" on the higher floors of the buildings (for architectural reasons). A lot of these columns are therefore "slopped" between levels 1-10, which would have been more difficult to achieve with concrete (for instance it would have required post-tensioned beams where the inclination of the columns change). This is why a steel solution with braced frames to ensure the lateral stability works better for that particular building.

There was no such issue with tower C since the core and columns could remain vertical from the foundation to the top of the building.

^ Finally! This is one massive site that will provide us with plenty of structural porn.

Well, it is the largest-scale skyscraper undertaking in American history.

I never would have guessed another building without a concrete core would be built in NY.

If you're making a reference to the twin towers, please note the insane thickness of the girders on this project, the relative strength of the steel compared to 40 years ago, not to mention the many CAD-enabled engineering redundancies. This tower will likely have several 'zones' that could fail and collapse independently of each other, without compromising the entire structure. This is the future of steel-frame construction in NYC.

That's for sure. I love those massive steel structures.

Not sure if the original post by ThatOneGuy was referring to the twin towers, but there are a number of other steel braced frames core in NYC: the New York Times building is one of the most recent example that comes to mind. There is also the Goldman Sachs building at 200 West street, the Hearst tower (steel core + the diagrid peripheral system), 5 Times Square, the Bertelsmann Building at 1540 Broadway, and many others...

Other buildings such as the Bloomberg tower (731 Lexington avenue) or Random House (230 West 56th street) have a steel core on the lower floors and concrete core above a transfer level.

Skin deep development with total ruthless maximizing of area. As we do not know the success of this development - it has to be as economical as possible, and it shows. The reason NY city has been successful so far is that it has avoided this type of moonscape street level development.
We give no credit to the success that 1982 NY City zoning did for the future of the city saving it from this.
Just as an example, in Paris, the business district is dead, and the life is where the city still exists as city for pedestrians. Same happening here.

Are we sure this is being built in NYC . j/k

This looks like something built in Japan, New Zealand, Chile, California or any other place with earthquakes with the potential to exceed MM 8.5.
