 Burj Khalifa History
                                 

 Introduction 

Today, we will learn about Burj Khalifa. The Burj khalifa is the tallest building in the world and a global symbol of modern engineering, ambition, and innovation. Located in Dubai, United Arab Emirates, this iconic skyscraper represents how a desert city transformed itself into a global business and tourism hub.   It is a story of vision for everyone in the world. It's for everyone's courage and human achievement.

Why Burj Khalifa Was Built:

Based on tourism, real estate, and global business. Sheikh Mohammed bin Rashid Al Maktoum imagined a landmark that would :
                               

   . Attract Global Investment
   . Showcase architectural excellence. With this one idea, he built a magnificent building so that the world could see Dubai. 

Who Planning and Design :
                             

The tower was designed by Adrian Devaun Smith was born August 19, 1944, and is an American architect.
He designed the World's largest structure. Burj Khalifa, as well as the building projected to surpass it, the Jeddah tower, is a longtime principal of Skidmore.

Studies:  When he was  4 years old, his family moved to Southern California, where he grew up. His drawing skills are good.

Smith

 He was inspired by Islamic architecture. The structure resembles the Hymenocallis flower. Y-Shaped design gives strength and stability.   

This design helps the building resist strong winds and Earthquakes.

Construction Timeline:    
Construction started in January 2004
.Structure topped out: January 2009
