Empire State Building
survivor of plane crash
When was it Built
The Starret bros. and Eken started construction in 1930 and finished in 1931. The design changed 16 times during the construction and planning but it still got completed ahead of schedule and took 1 year and 45 days. There was as many as 3500 workers at a time on the building and 5 people died during construction. The grand opening was on May 1st 1931
What is it Made Of
They used 60 000 tons of steel for the colomns and the beams to form a stable grid structure. For the outside layer, they used 200 000 cubic feet of limestone and granite, 10 million bricks and 730 tons of stainless steel and aluminium. They used these materials because they are extremely durable and would hold up. The cost to build the Empire State Building was $24 718 000 including the materials and if you add the cost of buying the property, the total is $40 948 900.
Why is it Shape the Way It Is
They built the Empire State Building extremely tall because the companies were having a competition with Walter Chrysler to see who could build the tallest building. The Chrysler building was finished first so at the time it was the taller building. However, when the Empire State Building was finished it was two hundred and four feet taller. It also claimed the title of the tallest building in the world. Including the lightning rod, it's 1454 feet tall and it has 102 floors.
Because the building is so tall, the builders had to use durable materials. They used a steel grid so it won't giv in to gravity because the have the columns and the beams going horizontally and vertically. A grid is a strong and durable structure and is very suitable for a building as tall as it is. Also the bottom section is bigger than the top which forms a stable bottom to hold the rest up.
On the morning of Saturday 28th July 1945, a B-25 pilot flying his way towards Newark airport got lost in fog and crashed intot the 78th and 79th floors of the Empire State Building. The explosion killed the planes crew and several volunteers working at the building that day. Structual damage was limited and the building was fully restored at a cost of $1 million and the elevator service fixed within weeks.
