Development is the key word in the dictionary of the modern man of today and of the means of development are the infrastructures around which he builds his life.
The world today is home to some of the tallest, deepest and even the longest building of all times that are absolute engineering marvels.
The title of the tallest building of the world goes to the Burj Khalifa in Dubai, that is almost 800m tall and houses some the world’s topmost offices, hotels, and restaurant as well as being a residential dwelling for many of Arab’s richest.
Among the longest structures of the world, the title is clearly taken in by the Great Wall of China, which can reportedly be seen even from the moon.
