Saudi Arabia's Impossible Tower...
Why It Matters
The project could set a new benchmark for megatall construction, reshaping global skyscraper competition and influencing future urban‑vertical development strategies.
Key Takeaways
- •Rise Tower aims to reach 2 km height in Riyadh
- •Project envisions vertical city for 50,000 residents and workers
- •Uses ultra‑high‑performance concrete and aerospace‑grade steel alloys for structural integrity
- •Requires maglev elevators and massive tuned‑mass damper to limit sway
- •Estimated cost exceeds $5 billion and demands 200 MW power supply
Summary
The video examines Saudi Arabia’s proposed Rise Tower, a 2‑kilometre‑tall skyscraper slated for Riyadh that would dwarf the Burj Khalifa and function as a self‑contained vertical city.
Design plans call for 678 floors, housing over 50,000 people with residential, office, hotel, retail, school and hospital space. To support the unprecedented height, engineers propose a 100‑metre deep concrete mat foundation, ultra‑high‑performance concrete five times stronger than standard, and aerospace‑grade steel alloys, while a 3,000‑ton tuned‑mass damper would mitigate sway.
Because conventional elevators cannot span 2 km, the tower would combine carbon‑fiber‑cabled lifts for lower levels with magnetic‑levitation elevators for the upper sections, delivering a 15‑minute ride to the summit. Power demands are projected at 200 MW, with only a fraction supplied by rooftop solar and wind turbines, the rest drawn from the grid.
If realized, the Rise Tower would redefine skyscraper engineering, test new materials and vertical‑transport technologies, and signal Saudi Arabia’s ambition to diversify its economy, while also raising questions about sustainability, safety and the livability of ultra‑high‑density vertical communities.
