By Edited Jun 11, 2015 0 0

The magnificent edifice Burj Khalifa, located in Dubai, United Arab Emirates, is the tallest building of the world.  Burj Khalifa is a very high structure with a height of 828 meters (2,717 feet).  It took around 5 years for the completion of the work of this tallest man-made structure.  Burj Khalifa was officially inaugurated on 4 January, 2010.  The building houses both commercial and apartment blocks.  This architectural marvel was designed by the construction engineering firm Skidmore, Owings and Merril of Chicago.  Adrian Smith was the chief architect of Burj Khalifa, under whose supervision the construction was completed.  It was Emaar Properties which undertook the construction of Burj Khalifa.

The construction cost of Burj Khalifa was around $1.5 billion.  Burj Khalifa won the 2010 Best Tall Building Middle East & Africa award.  This award is conferred by the Council on Tall Buildings and Urban Habitat and is considered an international honor in the construction industry.

This tallest building of the world has a unique structure.  The building Burj Khalifa has a unique design.   The structure houses 30, 000 homes, the 12-hectare (30-acre) man-made Burj Khalifa Lake, 19 residential towers, nine hotels such as The Address Downtown Dubai, 3 hectares (7.4 acres) of parking space and the Dubai Mall.

Historically, the Middle East was the location of tallest buildings and structures in the past.  With Burj Khalifa, the Middle East has again become prominent in architecture.  The Middle East had been the location of the tallest structure for centuries in the past.  The Great Pyramid of Giza is in the Middle East and for nearly 4000 years it had the singular distinction of being the tallest free-standing structure of the world.  Then in 1311 the Lincoln Cathedral of England superseded the Great Pyramid of Gaza.  Now, with the construction of Burj Khalifa, Middle East has again become the location of the tallest structure of the world.  This is part of the government policy of tourism promotion.  This is aimed at giving a new direction to the oil-dependent economy.

Hymenocallis, the Desert Flower

One significant aspect of Burj Khalifa is its unique architecture.  The building conforms to the Islamic architectural features.   Burj Khalifa is Y-shaped in its structure.  The Y-shaped construction makes it ideal for living because the special design affords maximum outside view and also sufficient air circulation.  The building has hotel accommodation and residential units.  As the building is in the Y-shape, the apartments and other blocks get sufficient natural light. 

The idea for the Y-shaped special design of BurjKhalif is derived from the shape of the desert flower Hymenocallis.  The building has the buttressed core system for the support of the excessive height and hence Burj Khalifa is more secure in spite of its height.   It has a hexagonal core reinforced by three buttresses.  This structure gives it the ‘Y’ shape. There is the hazard of the building being twisted because of the excessive height.  This special pattern in design protects the building from the danger of twisting.

It is a matter of amusement that as part of decoration, a collection of more than 1,000 pieces of art is arranged in unique artistic taste inside Burj Khalifa.  As a special effect, the work of Jaume Plensa is arranged in the residential lobby of Burj Khalifa.  As another unique feature, 196 bronze and brass alloy cymbals are arranged.  These cymbals represent 196 countries of the world.  The spot is memorable for the distinct timbre of the sound of water falling on leaves.
