Apparently the construction worker fell into an interior shaft of some sort, not from the perimeter of the building. Safety harnesses certainly should be required for anyone working near a shaft, especially if they are installing protective barriers designed to prevent accidents like this one or the flooring if a new level. I still havenāt seen any precise details about this event.

That really sucks. I wish his/her family, friends and co-workers well.

Does this accident put construction on hold?
Doubt it.

that site is shut down. probably will be weeks.
they always allow the job to keep working specifically to address safety and housekeeping issues, but new construction stops.

I feel sorry for the worker who recently passed, RIP
I do have a question though, from that last pic of 270 and 383 Madison it looks like 270 is at or slightly higher than 383. Am I seeing that correctly?

Someone share my IG story so that people donāt go around thinking this building has a concrete core or wondering where it is 
.
Brought my camera to work so hoping to walk over and take some pics afterwards.

The video states that the construction is different from the standard ācore firstā construction. The core is being built with the floorplates, similarly to One Vanderbilt. Notice in some tower construction, you can see the steel core one floor above the steel beams, but here itās all being done in one move. The 3d model they show does show a concrete core in 3 sections, but thats to simulate when the work is nearly done, after they cover the steel framed core with rebar and concrete for strength

most NYC office buildings were built with a steel core, unlike other places in the US or world.
as someone from NY, ive always viewed the steel core as normal, and the concrete core, first or last, as something that was different from normal.
One Vanderbilts steel core was temporary, to allow steel construction to proceed unabated as fast as possible. The permanent structural system is a concrete core with the temporary steel component contributing to the tension capacity of the core, like rebar.
Tower A at hudson yards was another recent steel only core system. In a building like that, or 270, the ironwork is so big, its mass alone has a contributory factor to the capacity of the building.

I noticed this in their Instagram video, but Iām not sure if the same wording is used in their longer YouTube version:
Itās a small error/ambiguity tangential to the main point of the segment, but I think it is an important point to clear up confusion about as TKDv intendsā the differences between a steel-framed core and a structural concrete core are pretty fascinating! If I understand correctly, the steel core is not necessarily fireproofed with concrete.

fireproofing, nowadays, is not done with concrete. Its cementitious spray on compound.
Back in the day, when labor was much less expensive, fireproofing was in fact done with concrete encasement.
270 may have concrete around certain life safety systems, like stairs or possibly elevators, or some critical MEP, but that is strictly non structural.
