OverBuilt

About the channel

OVERBUILT takes apart the biggest, boldest things humanity ever engineered — supertall towers, mega-dams, record-breaking bridges, tunnels, and the giant machines that built them — and shows how they actually worked. Each one was over-engineered to survive the impossible. Some did. Some failed spectacularly. Every video is a cinematic post-mortem: the ambition, the physics, the single overlooked detail, and the disaster that followed. No talking heads. No filler. Just archival footage, clean motion graphics, and the real engineering — explained so anyone can follow it. New post-mortems regularly. Subscribe to find out how it was built, why it broke, and what we should have learned.
