Autodesk freedom tower

Not only can users design in 3D, they can also hold project information and documentation in one central 3D model so that changes can be coordinated.

Say you went to an interior elevation on a sheet of drawings and moved the door over by 2ft, the plan, corresponding elevations, schedules and so on would all be coordinated instantly, regardless of which sheets they were on. In this way, the building is in effect built and analysed within the computer before it is built in reality. The firm selected Revit because of its ease of use, associative views, scheduling capabilities and integration with other products, such as AutoCAD.

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. All this is criss-crossed by subway tunnels, plus existing water and power conduits.

This was where Revit made an immediate impact. Users found that with the 3D model they could go into their complex design in an intuitive, easy-to-learn manner.

Now, they can model building components which have direct links to their actual characteristics. By using BIM, architects are responsible for assembling parts of a single structure, simulating their ideas in three dimensions, as in real life. Ric Hammond, AIA.

And I can't see what they have done to address it creatively.

Message 23 of The Freedom Tower is being designed and documented in Revit Message 24 of But don't quote me. Message 25 of I've read that there's a lot of especially large firms out there, utilizing Revit and ADT in this fashion.

I wonder if this has anything to do with the current shortage of proficient Revit production-level workforce? Maybe, in the future, as the Revit trained workforce expands; this 'hand-off' may not be as necessary? Message 26 of That's exactly the way my reseller is describing it to me.

Revit works best with users more versed in the construction of the building. Message 27 of The big projects we got going on Revit that are also using ADT for the CD's is because of team, training, and time demands. But as it is now, we've got a handful of folks that are up to speed to that level, so we do some stuff in Revit, some stuff in ADT, and get a lot of bang for our buck in the short term for these big projects.

It really depends on the team, training time, ect You don't gain much switching systems mid-swing, and you can totally do Cd's in Revit pretty efficiently. For me, I was sat at work in London, when a friend from North America rang to say a plane had flown into one of the Twin Towers.

From that point, a continuous stream of the most unbelievable and terrible events just kept on coming, suddenly nowhere felt safe.

These iconic buildings were completed in and and were briefly the tallest buildings on the planet with their stories dominating the New York skyline. The towers were probably the best known examples of tube buildings, with a main core, strengthened by closely spaced columns and beams in the outer walls. The decision to rebuild was political, commercial and a matter of national interest and pride.

With so much interest and competing ideas, whatever got chosen was bound to have its detractors and critics. Should it be higher? Others wanted a memorial park only. The Lower Manhattan Development Corporation initiated a competition inviting nine star architects to submit designs.

This happens in many major public works but perhaps in this case, not quite as publically. The design also incorporates a reference to the torch of the Statue of Liberty. That said, the new Freedom Tower design retains key elements of the original, including 2.

The revised Freedom Tower features a cubic base rather than a parallelogram as originally conceived , and has been set back further from one street identified as being a place where a possible threat could be launched. As the tower rises from its cubic base, its square edges chamfer back, transforming the square into eight tall isosceles triangles in elevation. At its middle, the tower forms a perfect octagon in plan and then culminates in an observation deck and glass parapet elevation 1, feet and 1, feet — the heights of the original Twin Towers whose plan is a square, rotated 45 degrees from the base.

The Freedom Tower has a robust and redundant steel moment frame, consisting of beams and columns connected by a combination of welds and bolts, and resists lateral loads through bending of the steel frame elements. Paired with concrete-core shear walls, the moment frame lends rigidity and redundancy to the overall building structure, while providing column-free interior spans.

Energy efficiency and environmental sustainability play a large role in the design. Construction of footings for the Freedom Tower is expected to begin in the first quarter of It is projected that steel for the building will be visible above grade in , with a topping out in SOM has completed more than 10, architecture, engineering, interior architecture, and planning projects in more than 50 countries around the world, specialising in the design of high-rise buildings.

Since the late 80s, SOM has been deeply involved in using advanced technology in its practice, even developing its own design software system, called AES. The firm has been a long time believer in the use of the virtual 3D model, integrating all building components including building systems and structural engineering.
