The race to build the world’s tallest skyscraper is a story of ambition, engineering genius, and national pride. For over a decade, Burj Khalifa in Dubai has held the crown at 829.8 meters. But Saudi Arabia’s Jeddah Tower is poised to claim that title once completed. This article compares these two supertall structures in detail, examining their heights, designs, costs, and engineering challenges. Understanding what sets them apart is essential for anyone following modern skyscraper construction, especially as the next landmark in vertical urbanism takes shape.

Burj Khalifa: The Current Record Holder
Burj Khalifa, located in Dubai, United Arab Emirates, is currently the tallest man-made free-standing structure in the world. It was officially opened on January 4, 2010, after nearly six years of construction. The building soars to a height of 829.8 meters (2,722 feet) and contains 163 floors. Its design follows a neo-futuristic architectural style inspired by the Hymenocallis flower, with a Y-shaped floor plan that maximizes views and structural stability. The total construction cost was approximately $1.5 billion USD.
The building holds around 14 world records, including the tallest building, the highest occupied floor, the highest outdoor observation deck (At the Top, Burj Khalifa Sky at 555.7 meters), and the elevator with the longest travel distance (504 meters). The structural system uses a buttressed core design, where three wings arranged around a central core provide torsional resistance and lateral stability. The main contractor was Samsung C&T of South Korea, with structural engineering by Bill Baker of Skidmore, Owings & Merrill.

Jeddah Tower: The Future of Supertall Architecture
Jeddah Tower, originally named Kingdom Tower, is an under-construction supertall skyscraper in Jeddah, Saudi Arabia. When completed, it will stand at least 1,000 meters (3,280 feet) tall, making it the first building in history to reach the 1-kilometer mark. The tower will feature 167 floors, including two basement levels, and its top floor will be at an elevation of 668 meters. The preliminary construction cost is SR 4.45 billion (approximately $1.23 billion USD).
Construction began on April 1, 2013, with an estimated completion time of 63 months (5 years and 3 months). However, multiple factors have delayed the project: labor-related issues, the COVID-19 pandemic, and the economic ripple effects of the Russia-Ukraine war. As of mid-2022, construction was on hold. The architectural style is also neo-futuristic, but with a more streamlined, tapering form designed by Adrian Smith + Gordon Gill Architecture. The structural engineer is Thornton Tomasetti, and the main contractor is the Saudi Binladin Group. The owner is the Jeddah Economic Company, with backing from Kingdom Real Estate Development.

Head-to-Head Comparison: Dimensions and Specifications
The table below summarizes the 18 key parameters that distinguish these two megastructures. While Burj Khalifa is a completed and operational marvel, Jeddah Tower remains a work in progress with finalized design specifications. The comparison reveals just how ambitious the Jeddah project is, aiming to surpass the Burj Khalifa in nearly every measurable dimension.

Construction Challenges and Timeline Comparison
Burj Khalifa’s construction was a model of efficiency. From groundbreaking in January 2004 to topping out in October 2009, the building rose at an average pace of one to two floors per week. The construction workforce peaked at over 12,000 workers per day. The tower used 330,000 cubic meters of concrete and 39,000 tonnes of steel reinforcement. The project faced its own challenges, including the 2008 global financial crisis, but Dubai’s government stepped in with a bailout from Abu Dhabi, and the building opened on schedule in 2010.
Jeddah Tower’s story is different. Although it broke ground in 2013 with an initial completion estimate of 63 months, the project has encountered a cascade of delays. Labor disputes and the COVID-19 pandemic were early setbacks. More recently, the Russia-Ukraine war has contributed to rising material costs and supply chain uncertainty. As of 2022, construction is on an indefinite hold, raising questions about the project’s future. The longer the delay, the higher the total cost becomes, potentially eroding the financial viability of the $1.23 billion initial budget.

- Burj Khalifa’s timeline: 5 years from start to opening (2004-2009), completed on budget at $1.5 billion
- Jeddah Tower’s timeline: Started 2013, expected 5 years but now past 9 years and still on hold
- Key disruptors for Jeddah Tower: Labor issues, COVID-19 pandemic, supply chain costs from geopolitical tensions
- Funding: Burj Khalifa had government backing; Jeddah Tower relies on private investors and the Jeddah Economic Company
Engineering Marvels Behind Both Structures
Both towers push the limits of structural engineering, but they do so with different design philosophies. Burj Khalifa uses a buttressed core system where three wings arranged at 120-degree angles provide lateral resistance against wind loads. The Y-shaped floor plan reduces wind forces by confusing the wind patterns, preventing vortex shedding from synchronizing along the building height. The foundation is a 3.7-meter thick reinforced concrete raft supported by 194 bored cast-in-place piles extending 50 meters deep.
Jeddah Tower’s design is even more radical. Its tapering, asymmetrical form is shaped like a triple-lobed rocket, narrowing as it rises to minimize wind exposure at extreme heights. The structural system uses a central hexagonal core with outrigger walls extending to three corners, creating an extremely stiff yet lightweight frame. The foundation consists of 270 piles drilled 120 meters into the earth, making it one of the deepest pile foundations ever designed. At 1 km, wind forces become the dominant design consideration, and the tower’s aerodynamic shape is critical to its stability.

- Burj Khalifa foundation: 194 piles, 50 m deep, 3.7 m thick raft slab
- Jeddah Tower foundation: 270 piles, 120 m deep, setting records for pile depth
- Wind strategy (Burj Khalifa): Y-shaped plan disrupts vortex shedding
- Wind strategy (Jeddah Tower): Triple-lobed taper and asymmetric profile scatter wind loads
- Concrete used: Burj Khalifa used 330,000 m3; Jeddah Tower will require significantly more
Conclusion: Will Jeddah Tower Surpass the Burj Khalifa?
Jeddah Tower remains one of the most anticipated construction projects in modern history. If completed as planned, it will surpass Burj Khalifa in height, floor count, observatory elevation, and elevator travel distance. It will become the first man-made structure to exceed one kilometer, setting a new benchmark for the supertall building category. However, the path to completion is uncertain. Construction delays, rising costs, and geopolitical instability have cast a shadow over the timeline. Burj Khalifa, meanwhile, stands complete and operational, a proven success that continues to attract millions of visitors annually.
The comparison between these two towers is not just about numbers. It represents two different eras in skyscraper construction: one that succeeded through government-backed determination during the post-2008 recovery, and another that aspires to reach new heights despite a far more complex global landscape. Whether Jeddah Tower eventually rises to claim the title or remains an unfinished ambition, its design and engineering have already influenced how future supertall structures will be conceived.
