5 Amazing Mega Engineering in the World

[Estimated read time: 3 minutes]

From small as nano particles to big as giant earth study, Science and technology continue to amaze us. Today we will represent you 5 Mega Engineering examples that make you stand back in awe. A few decades ago, these constructions were even hard to imagine and today they really exist. But they were never easy to build and include years of effort, thousands of clever minds and physical work. Have a look…

It is horseshoe shaped like bridge on the edge of side canyon, the idea of David Jin (a business man from Las Vegas). Grand Canyon Skywalk is a major tourist attraction since March 28, 2007. The structure is 1,219 m above the Colorado River and extends 21 m front the edge. The project took around 1 year to complete. 81,000 pounds of glass and 1 million pounds of steel is used to build the structure which can hold up to 71 million pounds.

It is an artificial Island in Dubai (finished construction 24 September 2008), in the shape of a palm tree. It is made up of 120 million cubic meters of rock, limestone and sand combined. The outer ring of the island took 100 million cubic meters on its own. The material that was used in construction was enough to build a thin wall around the earth thrice.

It is an international airport located on an artificial island in Osaka. It took around $20 billion to turn a whole project into reality. It was completed by 1994 and was the first ever airport built on the island. Because of much crowed area in Japan, engineers decided to construct an airport on the island which turned into one of the most expensive civil engineering project in the world. It took them 3 years, more than 10 thousand workers and 80 ships to excavate the 21 million cubic meter landfill to build Kansai Airpot.
