History

-The first building in the site of the Empire State was the John Thompson Farm in the late 18th century. But in the late 19th century, the block was occupied by the Waldorf-Astoria Hotel. 

 

-The Empire State was disigned by William F.Lamb from the architectual firm Shreve Lamb and Harmon, using its earlier designs for Reynolds Building as a basis .

 

-Excavation of the site begans on January 22, 1930. But the construction started on March 17.This project involved 3,400 workers (mostly immigrants from Europe).The Building was open to the people in May 1, 1931.

 

-The construction was part of an intense competition in New York for the title of "word's tallest Building" but Empire State competed with 40 Wall Street and Chrsler Building and finaly they win.

Characteristics of the structure

Which specific characteristics were taken into account and resolved?

The highest windy

Curiosities:

-At 9:40 am on Saturday, July 28, 1945, a B-25 Mitchell bomber, crashed into the north side of the Empire State Building,. One engine shot through the side opposite the impact and flew as far as the next block, where it landed on the roof of a nearby building, starting a fire that destroyed a penthouse. The other engine and part of the landing gear plummeted down an elevator shaft. Fourteen people were killed in the incident, but a  elevator operator Betty Lou Oliver survived a plunge of 75 floors inside an elevator, which still stands as the Guinness World Record for the longest survived elevator fall recorded.
