Built On Earth✓

Built on Earth explores the world's greatest megaprojects, infrastructure and engineering achievements — and the stories behind how they were built. From massive bridges and tunnels to high-speed railways, skyscrapers, dams, airports, ports and futuristic cities, we break down the engineering, money, challenges and decisions behind the projects reshaping our world. Discover how impossible structures are engineered, why some megaprojects succeed while others fail, how much they really cost, and what happens when ambition meets engineering reality. Expect in-depth stories about megaprojects, infrastructure, civil engineering, construction, transportation, architecture, urban development, energy projects and engineering failures from around the world.
