[attachment=46411]
The Empire State Building remained the tallest man-made structure in the world for 23 years before it was surpassed by the Griffin Television Tower Oklahoma (KWTV Mast) in 1954. It was also the tallest free-standing structure in the world for 36 years before it was surpassed by the Ostankino Tower in 1967.
The longest world record held by the Empire State Building was for the tallest skyscraper (to structural height), which it held for 42 years until it was surpassed by the North Tower of the World Trade Center in 1973.
About empire state building
The Empire State Building was the highest building in the world for forty Years. It was constructed in New York (USA) an era when American cities such as Chicago and New York competed to have the highest skyscrapers.

Designers
The architects, Shreve, Lamb and Harmon Associates, were given the brief of creating the tallest building in the world. To achieve this they decided to use a steel frame as the basic construction technique.

THE TECHNOLOGY OF CONSTRUCTION
In its day, the Empire State Building was constructed using up to date technology. A substantial concrete base was laid as a foundation to take the weight of the steel framework of the building. All the steel sections were prefabricated, that is, manufactured in a steel mill and transported to the construction site. The sections were manufactured to exact sizes to within 2mm tolerance and prepared so that they could either be bolted together or joined with rivets. It only took three days for the sections to be manufactured in the steel mill, transported and positioned in the framework as part of the buildings structure.
