Burj Khalifa: How the Tallest Building on Earth Actually Stands Up

Burj Khalifa is an engineered gesture: a single 828-meter tower, three wings around a buttressed central core, drawn on paper and raised on open desert to be the tallest building on earth. Standing at its foot, the thing to understand is not the height alone but the reasoning behind the height, the way a structure this tall was solved and why a young Gulf city chose to solve it at all. The record is real. The more interesting story is the grammar underneath it.

The number, and what it costs to reach it

The tower stands 828 meters to the top of its spire; the very tip is 829.8 meters, by the count of the CTBUH, the council that keeps the world's tall-building records. Emaar, the developer, counts more than two hundred stories, with 160 levels people can live and work in; the CTBUH counts 163 floors above ground. It is the tallest building in the world. It was built from 2004 to 2010 and inaugurated on the fourth of January, 2010.

Numbers like these are easy to recite and hard to feel. What they conceal is the central problem of any supertall: holding up something this slender against the wind. The design answer here is legible from the ground if you know where to look. The floor plan is a Y, three wings joined at a central core. The tower was designed by the American firm Skidmore, Owings and Merrill, with Adrian Smith as design partner, and SOM's engineers designed its structure. SOM describes it plainly: the three wings buttress one another through a six-sided central core, so the whole tower behaves more like a tripod than a mast.

Why the shape steps back

Look up and you will see the wings step inward as the tower climbs, dropping away at intervals in what SOM calls an upward spiraling pattern. That setback geometry is not styling: each step trims the tower's mass as it rises, so the top is a slim shaft and the last stretch is a spire. Emaar describes the plan as an abstraction of the six-petaled desert flower Hymenocallis, and SOM also points to patterning systems in Islamic architecture. It is a rare case where an ornamental reference and a structural solution happen to be the same shape.

Everything else you will encounter on the walk is arranged around this single point. On the walk, the tower's foot is stop nine, where you look straight up the wings, and stop ten, across the water, is where the height and the name are told.

The name and the timing

The tower was built as Burj Dubai, which simply means the Dubai tower, burj being the Arabic word for tower. It was renamed on its opening night, the fourth of January 2010, for Sheikh Khalifa bin Zayed Al Nahyan, then President of the United Arab Emirates and Ruler of Abu Dhabi. Reporters noticed the timing. A month earlier, in December 2009, Abu Dhabi had stepped in with ten billion dollars to help Dubai through the debt crisis. Neither government tied the two together; Dubai framed the name as an honor. The name is a piece of history either way, fixed to the side of the tallest building in the world.

It is worth stating plainly, because it is part of the honest account of this building: Emaar's own figures say engineers, designers, architects and skilled workers from more than a hundred countries built it, with more than twelve thousand people on site at the peak of construction and twenty-two million man-hours of work. The main contractor was the South Korean firm Samsung C&T. The people who raised the structure came, in large part, from elsewhere, which is true of Dubai's built environment as a whole.

Reading it from the ground

You do not need a ticket to understand the Burj Khalifa. The observation decks are ticketed, and their entrance is inside the Dubai Mall, but the entire ground-level experience is free. The single most useful thing you can do standing here is walk the promenade around the lake and watch the three wings slide past one another. From one position the tower reads as a slim blade; move along the water and it thickens into a broad, stepped mass. That shift is the buttressed-core plan revealing itself, and it is the clearest way to grasp that the height is a consequence of the geometry, not a decoration on top of it.

One practical note the structure imposes on you: this is a desert. The comfortable season runs roughly from November to March. In deep summer, from about June to September, the outdoor approach becomes genuinely taxing, so do the walk in the early morning or after dark, when the tower is illuminated and the heat has broken. Carry water even in winter, because the dry air dehydrates faster than you expect.

The tower as the first word

Read on its own, the Burj Khalifa is a superlative. Read as a stop on a walk, it becomes a thesis statement. It sits at the center of Downtown Dubai, which Emaar Properties, the single company that developed it, calls the five-hundred-acre community, on former open desert. The lake, the choreographed fountain, the vast mall that works as an air-conditioned town square, the new souk and old town built in an old style, and the dhow-shaped opera house are arranged around this spire, conceived together and raised in little more than a decade. Most cities are a palimpsest written over centuries. This one was written in a single hand.

That is why the tower rewards a walk rather than a photograph. The best way to understand what a supertall means to the city built around it is to circle it and follow its logic stop by stop. The self-guided audio walk Burj Khalifa and the Dubai Fountain: Built Around a Lake is a loop of twelve stops round Burj Lake on the free promenades, just over two kilometers in about an hour and a quarter; it is best from late afternoon into the evening, when the fountain plays every half hour from six to eleven. For the rest of the city, see the Dubai walking tours and the Dubai page. The tower is the first word. The rest of the walk is the sentence.
