That's what I thought. I wonder if he was really talking about 2WTC, because the building has been capped and already slumbered. It would make sense that it would take a couple of months to restart construction on 2WTC, but 3 is still active.

He was clearly refering to 2WTC. 3WTC's concrete contractor can resume work in a matter of weeks.

That doesn't make much sense considering the building has always been planned to be 88 stories. They certainly won't be reworking the existing core for continuing construction.

aside from being a better raw material, connection design for steel frames allows for a lot more options to meet forces.

we see the concrete encasement to supplement the steel and to act as 'even better' fireproofing. the purpose of the core itself is shear strength. The concrete portion is truely to create a secure area of the building that contains the transportation, utilities, emergency access in the event of a fire or whatever.

the twins were inherently weak because the core was small, unprotected, and required the outer wall to share the load. they used bar joists to hold the floors. Bar joists are garbage. The floors were actually prefabricated off site and set in place as panels. The purpose of this design was to create massive amounts of uninterrupted floor space.

The ESB is a traditional beam, column, brace frame building. The loads of the building area shared all over the place as it has a crazy amount of column lines. Its incredibly dense with steel. Its floor area ratio is incredibly stout for a building of that height.

Sears is not core driven, but it is much more traditional when compared to the twins. probably closer to the ESB
Though what you said is true, the "concrete is inferior to steel" argument is a myth. Both have advantages and disadvantages, and can function well as any type of structure. The main difference is in cost. Steel is very expensive but cheaper to build, while concrete is inexpensive but more expensive/labor intensive to build. This is why in Asia, concrete is used more often because of inexpensive laborers and an excess of concrete, while steel is somewhat less available and thus more costly to import, added to the already higher cost of steel...plus moment frames are also expensive. In the US, concrete would be an option, but due to worker unions, and such, paying for the labor force to build a concrete structure would be greater than in an other place. And steel is more inexpensive in the USA anyway due to the forgeries we have here.

2WTC is 88 floors, that's what he had to have been talking about...this tower is 80 floors and Otie said that they can resume core work in a matter of weeks on this.

New model, using pictures. There are minor discrepancies for functional and complexity reasons.

Nice way to start the new year.

3 World Trade is up & coming

By DAVID SEIFMAN City Hall Bureau Chief
Last Updated: 4:50 AM, January 2, 2013
Posted: 2:18 AM, January 2, 2013

"Another tower at Ground Zero could soon be on the rise.

Developer Larry Silverstein is “closer than anyone realizes” to landing tenants that would allow him to complete Tower 3 at the World Trade Center, Mayor Bloomberg told The Post.

“I think we’re pretty close downtown at the World Trade Center — closer than anybody realizes — to getting tenants for [Tower] No. 3,” the mayor said during a year-end interview last week.

The likely anchor tenant is GroupM — a subsidiary of the world’s largest advertising company, WPP — which a source said is in “advanced talks” to sign a lease.

GroupM has been looking to consolidate its operations in the city by leasing about 550,000 of the 2.8 million square feet in Tower 3, an 80-story structure Silverstein hopes to construct by 2015.

The law firm of White & Case has also been reported to be looking for space in the same building.

Tower 2, meanwhile, is not making similar progress, Bloomberg said.

During the interview, Hizzoner said Tower 2 was “way down the road. You’d have every building but 2 going.”

Tower 3 became a question mark last year when prospective tenants — including Morgan Stanley and UBS — lost interest amid concerns about slowing growth in the financial industry...

...Speaking of the mayor, Stephen Ross, the developer of Hudson Yards, said: “He’s got to get one more tenant for the first big building and then the platform [over the rail yards] makes sense.

“Once you have the platform,” he added,“the West Side is going to be residential and that’s easy to finance. That will not be a problem.”

Wow, these are awesome news. Would be awesome if the building would be completed in 2015

Let's get #3 going first, then worry about #2 (as much as I wish it were the other way around).

Very positive sign! Hopefully something is finalized soon. It'd be nice to see this one at least 40 or 50 stories high by the end of the year.

Agreed that would be great, certainly sounds like one or both of these potential deals are going to happen. Both of which meet the requirements to get it back on track.

Now I have to model the rest of the tower, darn. Any one know what the average spacing between slabs is above the podium?

All Silverstein towers have an average height of 13'-6" slab to slab.

That would be ambitious, even when the contracts were signed today. But things are looking good.

... I should have asked earlier. I'll have to rework the base. I was only a foot off. I'll figure the approximate heights of the podium levels by scaling my photograph based spacing into the space left by 1168'-(13.5'x73)

I am not convinced until the day the formwork is back.

T3 clearly is proceeding. The mayor is a billionaire and does not speak lightly. It would nice if the tenants persuaded Larry to restore the bracing.

The new version didn't only removed the cross bracing but re-arranged the whole structural system, it won't come back.
