Is the Burj Khalifa’s Spire Really 4,400 Tons?
Is the Burj Khalifa’s Spire Really 4,400 Tons?

When I published my video about the Burj Khalifa, many viewers doubted the claim that the spire weighs 4,400 tons. Some suggested it might only be 440 tons. To settle the debate, I decided to run a mass analysis using SolidWorks.
The CAD model of the spire
I found the exact blueprints for the spire online. It has a length of 244 meters and a maximum diameter of 1.2 meters. For the simulation, I assumed a material thickness of two inches, which is a fairly reasonable estimate. Take a look at the CAD model; the spire appears incredibly thin because its length is so enormous relative to its diameter. You can also notice the three stage diameter variation of the spire.
Regarding the two inch material thickness I selected, please have a look at this famous photograph of Tom Cruise. Material thickness is visible in this photograph. Our CAD model and the photograph resemble almost the same material thickness.
Mass Analysis
Now for the main event: the mass analysis. As you can see, SolidWorks calculates the mass at 3,904 tons.
Keep in mind that this analysis excludes external attachments like antennas, lightning arrester, and swirl breakers. Once you include those, the total weight easily reaches the 4,400-ton mark.
This spire might look like a toothpick from a distance, but it is actually a giant—a 244-meter tall giant weighing 4,400 tons.
