88 Years Ago Today; A Skyscraper Icon is Dedicated

https://en.wikipedia.org/wiki/Empire_State_Building



Construction
Demolition of the old Waldorf–Astoria began on October 1, 1929. Stripping the building down was an arduous process, as the hotel had been constructed using more rigid material than earlier buildings had been. Furthermore, the old hotel's granite, wood chips, and "'precious' metals such as lead, brass, and zinc" were not in high demand resulting in issues with disposal. Most of the wood was deposited into a woodpile on nearby 30th Street or was burned in a swamp elsewhere. Much of the other materials that made up the old hotel, including the granite and bronze, were dumped into the Atlantic Ocean near Sandy Hook, New Jersey.

By the time the hotel's demolition started, Raskob had secured the required funding for the construction of the building. The plan was to start construction later that year but, on October 24, the New York Stock Exchange suffered a sudden crash marking the beginning of the decade-long Great Depression. Despite the economic downturn, Raskob refused to cancel the project because of the progress that had been made up to that point. Neither Raskob, who had ceased speculation in the stock market the previous year, nor Smith, who had no stock investments, suffered financially in the crash. However, most of the investors were affected and as a result, in December 1929, Empire State Inc. obtained a $27.5 million loan from Metropolitan Life Insurance Company so construction could begin. The stock market crash resulted in no demand in new office space, Raskob and Smith nonetheless started construction, as canceling the project would have resulted in greater losses for the investors.

A structural steel contract was awarded on January 12, 1930, with excavation of the site beginning ten days later on January 22, before the old hotel had been completely demolished. Two twelve-hour shifts, consisting of 300 men each, worked continuously to dig the 55-foot (17 m) foundation. Small pier holes were sunk into the ground to house the concrete footings that would support the steelwork. Excavation was nearly complete by early March, and construction on the building itself started on March 17, with the builders placing the first steel columns on the completed footings before the rest of the footings had been finished. Around this time, Lamb held a press conference on the building plans. He described the reflective steel panels parallel to the windows, the large-block Indiana Limestone facade that was slightly more expensive than smaller bricks, and the tower's lines and rise. Four colossal columns, intended for installation in the center of the building site, were delivered; they would support a combined 10,000,000 pounds (4,500,000 kg) when the building was finished.

The structural steel was pre-ordered and pre-fabricated in anticipation of a revision to the city's building code that would have allowed the Empire State Building's structural steel to carry 18,000 pounds per square inch (124,106 kPa), up from 16,000 pounds per square inch (110,316 kPa), thus reducing the amount of steel needed for the building. Although the 18,000-psi regulation had been safely enacted in other cities, Mayor Jimmy Walker did not sign the new codes into law until March 26, 1930, just before construction was due to commence. The first steel framework was installed on April 1, 1930. From there, construction proceeded at a rapid pace; during one stretch of 10 working days, the builders erected fourteen floors. This was made possible through precise coordination of the building's planning, as well as the mass production of common materials such as windows and spandrels. On one occasion, when a supplier could not provide timely delivery of dark Hauteville marble, Starrett switched to using Rose Famosa marble from a German quarry that was purchased specifically to provide the project with sufficient marble.

The scale of the project was massive, with trucks carrying "16,000 partition tiles, 5,000 bags of cement, 450 cubic yards [340 m3] of sand and 300 bags of lime" arriving at the construction site every day. There were also cafes and concession stands on five of the incomplete floors so workers did not have to descend to the ground level to eat lunch. Temporary water taps were also built so workers did not waste time buying water bottles from the ground level. Additionally, carts running on a small railway system transported materials from the basement storage to elevators that brought the carts to the desired floors where they would then be distributed throughout that level using another set of tracks. The 57,480 short tons (51,320 long tons) of steel ordered for the project was the largest-ever single order of steel at the time, comprising more steel than was ordered for the Chrysler Building and 40 Wall Street combined. According to historian John Tauranac, building materials were sourced from numerous, and distant, sources with "limestone from Indiana, steel girders from Pittsburgh, cement and mortar from upper New York State, marble from Italy, France, and England, wood from northern and Pacific Coast forests, [and] hardware from New England." The facade, too, used a variety of material, most prominently Indiana limestone but also Swedish black granite, terracotta, and brick.

By June 20, the skyscraper's supporting steel structure had risen to the 26th floor, and by July 27, half of the steel structure had been completed. Starrett Bros. and Eken endeavored to build one floor a day in order to speed up construction, a goal that they almost reached with their pace of ​4 1?2 stories per week; prior to this, the fastest pace of construction for a building of similar height had been ​3 1?2 stories per week. While construction progressed, the final designs for the floors were being designed from the ground up (as opposed to the general design, which had been from the roof down). Some of the levels were still undergoing final approval, with several orders placed within an hour of a plan being finalized. On September 10, as steelwork was nearing completion, Smith laid the building's cornerstone during a ceremony attended by thousands. The stone contained a box with contemporary artifacts including the previous day's New York Times, a U.S. currency set containing all denominations of notes and coins minted in 1930, a history of the site and building, and photographs of the people involved in construction. The steel structure was topped out at 1,048 feet (319 m) on September 19, twelve days ahead of schedule and 23 weeks after the start of construction. Workers raised a flag atop the 86th floor to signify this milestone.

Afterward, work on the building's interior and crowning mast commenced. The mooring mast topped out on November 21, two months after the steelwork had been completed. Meanwhile, work on the walls and interior was progressing at a quick pace, with exterior walls built up to the 75th floor by the time steelwork had been built to the 95th floor. The majority of the facade was already finished by the middle of November. Because of the building's height, it was deemed infeasible to have many elevators or large elevator cabins, so the builders contracted with the Otis Elevator Company to make 66 cars that could speed at 1,200 feet per minute (366 m/min), which represented the largest-ever elevator order at the time.

In addition to the time constraint builders had, there were also space limitations because construction materials had to be delivered quickly, and trucks needed to drop off these materials without congesting traffic. This was solved by creating a temporary driveway for the trucks between 33rd and 34th Streets, and then storing the materials in the building's first floor and basements. Concrete mixers, brick hoppers, and stone hoists inside the building ensured that materials would be able to ascend quickly and without endangering or inconveniencing the public. At one point, over 200 trucks made material deliveries at the building site every day. A series of relay and erection derricks, placed on platforms erected near the building, lifted the steel from the trucks below and installed the beams at the appropriate locations. The Empire State Building was structurally completed on April 11, 1931, twelve days ahead of schedule and 410 days after construction commenced. Al Smith shot the final rivet, which was made of solid gold.

The project involved more than 3,500 workers at its peak, including 3,439 on a single day, August 14, 1930. Many of the workers were Irish and Italian immigrants, with a sizable minority of Mohawk ironworkers from the Kahnawake reserve near Montreal. According to official accounts, five workers died during the construction, although the New York Daily News gave reports of 14 deaths[3] and a headline in the socialist magazine The New Masses spread unfounded rumors of up to 42 deaths. The Empire State Building cost $40,948,900 to build, including demolition of the Waldorf–Astoria (equivalent to $554,644,100 in 2018). This was lower than the $60 million budgeted for construction.

Lewis Hine captured many photographs of the construction, documenting not only the work itself but also providing insight into the daily life of workers in that era. Hine's images were used extensively by the media to publish daily press releases. According to the writer Jim Rasenberger, Hine "climbed out onto the steel with the ironworkers and dangled from a derrick cable hundreds of feet above the city to capture, as no one ever had before (or has since), the dizzy work of building skyscrapers". In Rasenberger's words, Hine turned what might have been an assignment of "corporate flak" into "exhilarating art". These images were later organized into their own collection. Onlookers were enraptured by the sheer height at which the steelworkers operated. New York magazine wrote of the steelworkers: "Like little spiders they toiled, spinning a fabric of steel against the sky".

Opening and early years
The Empire State Building officially opened on May 1, 1931, forty five days ahead of its projected opening date. The opening was marked with an event featuring United States President Herbert Hoover, who turned on the building's lights with the ceremonial button push from Washington, D.C.. Over 350 guests attended the opening ceremony, and following luncheon, at the 86th floor including Jimmy Walker, Governor Franklin D. Roosevelt, and Al Smith. An account from that day stated that the view from the luncheon was obscured by a fog, with other landmarks such as the Statue of Liberty being "lost in the mist" enveloping New York City. The building officially opened the next day. Advertisements for the building's observatories were placed in local newspapers, while nearby hotels also capitalized on the events by releasing advertisements that lauded their proximity to the newly opened tower.

According to The New York Times, builders and real estate speculators predicted that the 1,250-foot-tall (380 m) Empire State Building would be the world's tallest building "for many years", thus ending the great New York City skyscraper rivalry. At the time, most engineers agreed that it would be difficult to build a building taller than 1,200 feet (370 m), even with the hardy Manhattan bedrock as a foundation. Technically, it was believed possible to build a tower of up to 2,000 feet (610 m), but it was deemed uneconomical to do so, especially during the Great Depression. As the tallest building in the world, at that time, and the first one to exceed 100 floors, the Empire State Building became an icon of the city and, ultimately, of the nation.


Seen from the north

The Empire State Building's opening coincided with the Great Depression in the United States, and as a result much of its office space was vacant from its opening. In the first year, only 23% of the available space was rented, as compared to the early 1920s, where the average building would have occupancy of 52% upon opening and 90% rented within five years. The lack of renters led New Yorkers to deride the building as the "Empty State Building".

Jack Brod, one of the building's longest resident tenants, co-established the Empire Diamond Corporation with his father in the building in mid-1931[142] and rented space in the building until he died in 2008. Brod recalled that there were only about 20 tenants at the time of opening, including him, and that Al Smith was the only real tenant in the space above his seventh-floor offices. Generally, during the early 1930s, it was rare for more than a single office space to be rented in the building, despite Smith's and Raskob's aggressive marketing efforts in the newspapers and to anyone they knew. The building's lights were continuously left on, even in the unrented spaces, to give the impression of occupancy. This was exacerbated by competition from Rockefeller Center[136] as well as from buildings on 42nd Street, which, when combined with the Empire State Building, resulted in surplus of office space in a slow market during the 1930s.

Aggressive marketing efforts served to reinforce the Empire State Building's status as the world's tallest. The observatory was advertised in local newspapers as well as on railroad tickets. The building became a popular tourist attraction, with one million people each paying one dollar to ride elevators to the observation decks in 1931. In its first year of operation, the observation deck made approximately $2 million in revenue, as much as its owners made in rent that year. By 1936, the observation deck was crowded on a daily basis, with food and drink available for purchase at the top, and by 1944 the tower had received its 5 millionth visitor. In 1931, NBC took up tenancy, leasing space on the 85th floor for radio broadcasts. From the outset the building was in debt, losing $1 million per year by 1935. Real estate developer Seymour Durst recalled that the building was so underused in 1936 that there was no elevator service above the 45th floor, as the building above the 41st floor was empty except for the NBC offices and the Raskob/Du Pont offices on the 81st floor.

Per the original plans, the Empire State Building's spire was intended to be an airship docking station. Raskob and Smith had proposed dirigible ticketing offices and passenger waiting rooms on the 86th floor, while the airships themselves would be tied to the spire at the equivalent of the building's 106th floor. An elevator would ferry passengers from the 86th to the 101st floor[g] after they had checked in on the 86th floor, after which passengers would have climbed steep ladders to board the airship. The idea, however, was impractical and dangerous due to powerful updrafts caused by the building itself, the wind currents across Manhattan, and the spires of nearby skyscrapers. Furthermore, even if the airship were to successfully navigate all these obstacles, its crew would have to jettison some ballast by releasing water onto the streets below in order to maintain stability, and then tie the craft's nose to the spire with no mooring lines securing the tail end of the craft. On September 15, 1931, in the first and only instance of an airship using the building's mast, a small commercial United States Navy airship circled 25 times in 45 miles per hour (72 km/h) winds. The airship then attempted to dock at the mast, but its ballast spilled and the craft was rocked by unpredictable eddies. The near-disaster scuttled plans to turn the building's spire into an airship terminal, although one blimp did manage to make a single newspaper delivery afterward.

In 1932, the Fifth Avenue Association gave the tower its 1931 "gold medal" for architectural excellence, signifying that the Empire State had been the best-designed building on Fifth Avenue to open in 1931. A year later, on March 2, 1933, the movie King Kong was released. The movie, which depicted a large stop motion ape named Kong climbing the Empire State Building, made the still-new building into a cinematic icon.

On July 28, 1945, a B-25 Mitchell bomber crashed into the north side of the Empire State Building, between the 79th and 80th floors. One engine completely penetrated the building and landed in a neighboring block, while the other engine and part of the landing gear plummeted down an elevator shaft. Fourteen people were killed in the incident, but the building escaped severe damage and was reopened two days later.
