If you never gave it a thought, worlds best construction projects are quite admirable. Ranging from the International Space Station to industrial complexes, subways, dams, and airports, these are some of the largest and best construction projects the world has ever seen. These projects are much admired and some of them are widely reviled. One of the most stunning architectural achievements would be Terminal 1 in China.

This International Airport in Beijing is the work of art and the man who stands behind is it the most famous architect in the world Zaha Hadid. Speaking of airports, there is one more that needs to be mentioned and it is widely considered to be one of the worlds best construction project in the last decade. We are talking about Al Maktoum Airport in Dubai. The scale of this unbelievable achievement is almost astonishing.

It extends over more than 21 square miles and it was designed to handle 200 aircrafts. Saudi Arabia will continue to amaze us even so and this time it is all about Jubail 2, the industrial city project, started 22 years ago. They have some really outstanding figures there like 100 industrial plants, an oil refinery that is supposed to produce at least 350,000 barrels per day and so on. And that is not the end.

Dubailand, three times bigger than Disneyland, is stretching over 278 square kilometers. It has six parts, hotels, science attractions, health facilities, eco tourism, sports venues and theme parks. When it comes to the most astonishing achievements, building a construction in space is the last level for us as a species. Well, International Space Station can speak for itself alone. It was created by a whole consortium of 15 different nations. Five space agencies put their resources together for this amazing project that united the world with the same goal.

It circles our planet every 92 minutes. Now, we go to China again because their South to North Water Transfer project is really breathtaking. The north is the most populated are in China but there is a serious water shortage. This is the effort that should remedy that issue.
