Engineers used a hydraulic jacking system hidden inside the building’s core. They built the spire in sections, and like a periscope rising from a submarine, they pushed the spire up piece by piece from within the building. For the final 80 meters, they had to fabricate the steel on site and weld it manually—standing on a platform 750 meters above the ground. The spire isn't just there for bragging rights. It serves three vital functions:
When you look at a picture of the Burj Khalifa, your eye naturally travels up the sleek, stepped façade until it pierces the clouds. We all know the number: 828 meters (2,717 feet) . But here is a truth that surprises most people: without its spire, the Burj Khalifa would barely be taller than the Empire State Building.
Dubai gets high winds. Without a spire, the top of the Burj would sway violently. Inside the spire’s base is a massive tuned mass damper. It acts like a giant pendulum, swinging in the opposite direction of the wind to cancel out the motion. The spire is the building’s anchor . burj khalifa spire
To visualize that: The spire alone is taller than the Washington Monument (169m). It is taller than the entire Great Pyramid of Giza (138m). If you lifted the spire off the Burj and stood it on the ground in London, it would dwarf Big Ben. Here is the engineering nightmare: How do you install a 200-meter steel needle on top of a tower that is already swaying in the wind?
That needle at the top isn't just a decorative hat. It is a structural marvel, a logistical nightmare, and the secret to why this building holds the title of "World's Tallest." Engineers used a hydraulic jacking system hidden inside
The top of the spire (the very tip) is not accessible to tourists. It is accessible only to a handful of climbers per decade for maintenance. To get there, you have to climb a series of vertical ladders bolted to the inside of the steel structure. At the very top, there is a tiny service hatch.
The Burj’s spire is technically a sitting on top of the concrete core. The spire isn't just there for bragging rights
They didn't use a helicopter. They built it from the inside out .
