Vietnam Is Dumping 100 Million Cubic Meters of Material Into the Sea to Build a Massive Megacity

Vietnam is reshaping its coastline on an extraordinary scale. More than 100 million cubic meters of material are being placed into the sea to create new land for a massive $18 billion megacity near Ha Long Bay.

But creating land is only the beginning. Engineers must dredge soft seabed, stabilize weak ground, build massive foundations, construct bridges, and install an entire underground infrastructure network before thousands of buildings can rise above it.

Step by step, open water is being transformed into roads, neighborhoods, towers, and a new urban landscape designed for hundreds of thousands of people. In this video, Mandarin Tech takes you inside the engineering, machines, and construction methods behind one of Vietnam’s most ambitious coastal megaprojects.
