10 Fun Facts about Burj Khalifa

As the tallest building in the world, Burj Khalifa is an astonishing landmark in Dubai. It has a height of 828 meters and is considered an architectural marvel. The unique design and the wonders behind architecture make it an iconic attraction in Dubai. Here are 10 intriguing fun facts about Dubai's Burj Khalifa. We will also share a few things you didn’t know about Burj Khalifa. 

1. Burj Khalifa Has Over 160 Floors

The exact number of floors found in Burj Khalifa is one of its most astonishing stats. This towering skyscraper has 163 habitable floors above ground, 46 maintenance levels in the spire, and two basement levels. For reference, most skyscrapers have between 40 and 100 floors. The elevator system has a total of 57 working cars to reach every level. You can get to the observation deck using Burj Khalifa tickets without any significant delays. 

2. It Took Over 5 Years to Build

A structure as massive as Burj Khalifa, unsurprisingly, took many years of intensive construction to complete. It began its construction in 2004, commencing with foundation piles sunk over 50 meters deep. After over five years of dedicated construction, the exterior was finished in 2009. Interior decorating and fit-outs took another year before opening in January 2010. Plenty of documentaries are available online on Burj Khalifa’s construction facets. Make sure to look at them and learn more about how Burj Khalifa was built. 

3. There Are Enough Restrooms for 35,000 People

Being the world's tallest building and a major tourist attraction, Burj Khalifa needs to accommodate thousands of visitors daily. The building holds hundreds of restroom facilities to handle huge crowds. There are separate washrooms for men and women on nearly every occupied floor. With over 1,800 total fixtures, the building has restroom capacity for over 35,000 people at once.

4. The Foundation Piles Weigh Over 110,000 Tons Each

What lies beneath the surface is just as impressive. Burj Khalifa's stability starts with its robust foundation, anchored by 192 deep concrete piles. Each pile has a tremendous weight of over 500 tons. The total weight of all foundation piles combined is a staggering 113,000 metric tons of reinforced concrete to support the formidable building loads above.

5. The Building Consumes Over 36 million Gallons of Water Annually

Operating Burj Khalifa takes vast amounts of resources. Among them is water consumption by building systems and occupants. Supplying fresh water to countless floors uses over 36 million gallons every year to fill 55 Olympic-sized swimming pools. Water is provided through a modified desalination and district cooling system designed for efficient use even at such enormous scales.

6. The Building Sways up to 1.5 Meters at the Top

Although robust, the extreme height of Burj Khalifa means upper levels can still sway almost two feet back and forth at the top due to wind vortexes and dynamic live loads. Dampeners inside the spire structure help control and dissipate movement to prevent motion sickness for occupants on high floors. The skyscraper was designed using over 40 wind tunnel tests to maximize stability. However, you will not be able to experience this when you are at the top of the building. 

7. There Are 2,909 Stairs from Base to Tip

While elevators swiftly whisk visitors to the observation deck, ascending the building by stairwell is quite a feat. There are 2,909 stairs spanning 160 floors from the bottom to the tip of the spire. Climbing these stairs takes several hours of devoted effort. Yearly charity stair climb events see incredibly fit athletes race up the tower's stairs.

8. It Has the World's Highest Observation Deck at 555 Meters

Among Burj Khalifa's records is the status of having the world's highest outdoor observation deck. Known as At the Top SKY, this deck sits 555 meters up on the 148th floor. Open-air terraces with minimal barriers allow visitors to feel the outdoor winds and take in unmatched panoramic views over Dubai from this unmatched vantage point in the clouds.

9. Over 300,000 Cubic Meters of Concrete Were Used

As one would expect, erecting a structure as enormous as Burj Khalifa required vast quantities of building materials. Its 2,600-mile-long  sidewalk alone contains over 330,000 cubic meters of concrete. Exterior cladding includes over 26,000 glass panels and 15,500 square meters of embossed stainless steel.

10. The Tip Points Far from True North

Although appearing symmetrical from a distance, a fun architectural quirk is that the tip of Burj Khalifa is not actually aligned north. The spire apex leans about 1.5 degrees off-axis, pointed north-northwest. This misalignment was intentional to optimize the tower's structural integrity based on the path of prevailing winds. Even seemingly perfect structures have tiny flaws!

Final words

With its sheer colossal scale, record-setting height, and cutting-edge construction, Burj Khalifa has plenty of fun and fascinating facts behind it that make it such an iconic architectural achievement. Beyond being the world's tallest building, these details give a glimpse into the enormous complexity and engineering ingenuity involved in creating a true modern Wonder of the World.
