2. THE EMPIRE STATE BUILDING Location : Midtown Manhattan,  New york city Built : 1930-1931 Story : 102 Heigh t : 1250 feet (1454 feet with antenna ) Architect : Shreve lamb and Harmon Lifts/elevators : 73 Its name is derived from " Empire State ", the nickname of the state of New York. It stood as the world's tallest building until 1970 ( World Trade Center). its collapse in the September 11, 2001 attacks, the Empire State Building was again the city's tallest skyscraper until 2012. As of 2020, the building is the  seventh-tallest building in New York City , the  ninth-tallest completed skyscraper in the United States , the  48th-tallest in the world , and the  fifth-tallest freestanding structure in the Americas.

3. Site The site of the Empire State Building, located in  Midtown South  on the west side of  Fifth Avenue  between West   33rd  and  34th Streets , was originally part of an early 18th-century farm. It was developed in 1893 as the site of the  Waldorf–Astoria Hotel. In 1929, Empire State Inc. acquired the site and devised plans for a skyscraper there. The design for the Empire State Building was changed fifteen times until it was ensured to be the world's tallest building.

4. Lamb produced the building drawings in just two weeks using the firm's earlier designs  as the basis.  The 1916 Zoning Act forced Lamb to design a structure that incorporated setbacks resulting in the lower floors being larger than the upper floors. Consequently, the tower was designed from the top down, giving it a " pencil"-like shape.

5. The Structure of the tower is braced steel frame with semi-rigid connections. It remains stiffest of the tower for its height, due to largely due to heavy cladding that is designed to stiffen the frame. Single core system The system structure of a tall building with a centre single core (single core) and within short columns (mullion) which bear the floor with the core of the building. The core of the building except bears the vertical load is also burdened with a horizontal force due to the earthquake and wind. There are windows on four sides providing excellent light and views. Shear Walls: To resist the lateral load caused by wind and Earthquake The Assembly of shear wall is known as “Coupled Shear Wall” Belt Trusses distribute the tensile and compressive force to the large no of exterior truss.

6. The building's Art Deco architecture, height, and observation decks have made it a popular attraction. Around 4 million tourists from around the world annually visit the building's 86th and 102nd floor observatories; an additional indoor observatory on the 80th floor opened in 2019. 80TH FLOOR 86TH FLOOR 102ND FLOOR

7. The Empire State Building is an American  cultural icon . A symbol of New York City, the tower has been named as one of the  Seven Wonders of the Modern World  by the American Society of Civil Engineers. It was ranked first on the American Institute of Architects' List of America's Favorite Architecture in 2007. Additionally, the Empire State Building and its ground-floor interior were designated city landmarks by the  New York City Landmarks Preservation Commission in 1980, and were added to the  National Register of Historic Places as a National Historic Landmark in 1986.

8. Plans

9. The original plan of the building was 50 stories, but was later increased to 60 and then 80 stories . Height restrictions were placed on nearby buildings to ensure that the top fifty floors of the planned 80-story, 1,000-foot-tall (300 m) building would have unobstructed views of the city. While plans for the Empire State Building were being finalized, an intense competition in New York for the title of " world's tallest building " was underway.  The plans included an observation deck on the 86th-floor roof at a height of 1,050 feet (320 m), higher than the Chrysler's 71st-floor observation deck. The roof height was now 1,250 feet (380 m), making it the tallest building in the world by far, even without the antenna. The addition of the dirigible station meant that another floor,  The final plan was announced to the public on January 8, 1930, just before the start of construction.  ARCHITECT SKETCH OF HEIGHTS AND ALLOWED BUILDING AREAS

10.   CIRCULATON The elevators would ascend 167 feet from the 86th floor ticket offices to a 33-foot-wide 101st-floor  waiting room .   From there, stairs would lead to the 102nd floor. Total Lifts/elevators are 73. Visitors reach the 86th Floor Observatory by  elevator  in less than one minute.

11. Steel structure The exterior of the Empire State Building is composed of 200,000 cubic feet of  Indiana limestone  and  granite , 10 million  bricks  and 730 tons of  aluminum  and  stainless steel
