What is the Freedom Tower made out of?
Hybrid Concrete-and-Steel Structure The design of One WTC is very different from that of the twin towers. While they were held up by external steel columns, it has a hybrid concrete-and-steel structure. The key to its strength is a massive, extremely strong concrete core.
What were the original twin towers made of?
The core of each tower was a rectangular area 87 by 135 feet (27 by 41 m) and contained 47 steel columns running from the bedrock to the top of the tower. The large, column-free space between the perimeter and core was bridged by prefabricated floor trusses.
What were the World Trade Centers made of?
The WTC was primarily a lightweight steel structure; however, its 244 perimeter columns made it “one of the most redundant and one of the most resilient” skyscrapers.
How many workers died building the Freedom Tower?
In all, 60 workers were killed in construction accidents while the World Trade Center was being built.
What is the freedom stone?
This 20-ton solid granite monument was mined from the Adirondack Mountains and is flecked throughout with magnificent crystals of garnet, the official gemstone of New York. The Freedom Stone was unveiled by Governor Pataki and Mayor Bloomberg during the ground breaking ceremony on July 4, 2004.
What type of architecture is the Freedom Tower?

Contemporary architecture

Why was the freedom stone removed from ground zero?
But the piece, known as the “Freedom Stone,” never became part of the tower now called One World Trade Center. After security concerns forced a reconfiguration of the site two years later, the big rock was trucked away.
How many storeys are in the Freedom Tower?
When SOM won the bid to design Freedom Tower, its designers opted to test Revit on one portion of the project, namely the substrata. This element alone took up eleven storeys, including below-grade infrastructure and shopping facilities, as well as access to public transport and the World Financial Center.
How is Bim used in the Freedom Tower?
Manhattan’s Freedom Tower has set new standards in the use of Building Information Modelling (BIM). The Freedom Tower’s architects, along with the project’s structural and mechanical engineers, are able to work from elements of one model instead of separate documents.
Why was 3D modelling used for Freedom Tower?
3D modelling software has proved vital for Manhattan’s Freedom Tower. It has been pivotal in terms of coordinating plans, applying changes and speeding up decision-making. While New York’s most high-profile building site has already enjoyed its groundbreaking ceremony, designers behind the scenes continue to break new ground in other ways.
How did CSG model the Freedom Tower Building?
The Freedom Tower’s architects, along with the project’s structural and mechanical engineers, are able to work from elements of one model instead of separate documents. CSG used Revit and AutoCAD to model the tower’s foundations, buttress slabs, core walls and columns on the original designs.
