The Three World Trade Center, also known under the name of his address, 175 Greenwich Street, is a new skyscraper in New York City, which arises in the context of the new World Trade Center complex. Construction began in July 2010 and are expected to be completed in 2016 sein.Vorlage: Future / the building was planned in two years by British architect Richard Rogers.
Architecture
The Three World Trade Center ( German: World Trade Center building No. 3) is part of the new World Trade Center complex. In New York, the high-rise is (nearly 330 meters of the roof without spikes) will follow completion with a height of 357 m the sixth- tallest building, according to the One World Trade Center (541 m), 432 Park Avenue ( 426 m), the 411 m high Two World Trade Center, the Empire State Building ( 381 m ) and the Bank of America Tower (366 m). Originally a height of 378 m in plan, but this was slightly reduced to 357 m for a revision of the building concept. Inside the new World Trade Center, the tower will represent the third largest building. Above the roof is to follow, making the official building height is achieved at each corner a bit. The facade of the comprehensive 80 floors tower will consist exclusively of glass. At the front and back above the eighth floor originally large, intersecting steel bracing should be installed that are visible from the outside. This architectural concept was rejected again, so that a normal glass facade was unveiled in summer 2011. Most floors of the tower to stand for office available while are provided in the first eight rounds, the podium, shops and engineering controls. Inside, the building will have a massive reinforced concrete core, will be housed in the elevators, stairwells and utility lines. Through this Baueigenschaft the safety of the tower to be considerably increased. According to this principle all the skyscraper to be built in the new World Trade Center complex ( as are the majority of all high-rise buildings around the world ).
Realization
Dispute over the construction financing
The entire Ground Zero is owned by the New York Port Authority, but was leased to Silverstein Properties. Buildings 2, 3 and 4 World Trade Center will also be owned by Silverstein Properties, while the Port Authority has been entrusted with the construction of the tallest building, the One World Trade Center. Due to the ever-present economic situation, and there's less need for large office space, Silverstein Properties asked the Port Authority to help finance the towers 2, 3 and 4, or to vouch for a total of 3.2 billion U.S. dollars. The Port Authority ( Port Authority ) rejected this, however. They announced Silverstein to help with only $ 800 million to build a tower, namely the smaller Four World Trade Center, whose construction began in 2008. On 11 May 2009, the Port Authority proposed to convert the building Two World Trade Center and Three World Trade Center, only five-storey buildings, so to build only the podium of the towers. A complete waiver of both buildings is not possible because there is a complex underground infrastructure on the World Trade Center site because of the overall plan. This fact does not allow to waive any of the construction projects. Larry Silverstein, president of Silverstein Properties, declined, however, to reduce the two towers so. As a result, a dispute erupted over the future of the two buildings. The Port Authority sees it as too great a risk to invest in the construction of structures that may previously not have any existing tenants. Larry Silverstein argued, however, that he had the 7 World Trade Center, also built without that he had a tenant at the start of construction. Now Opened in 2006, the building is almost fully leased. Moreover, it was not to be expected that the small office supplies would last for many more years.
On 11 June 2009 a meeting between the Port Authority, Silverstein Properties and also now included in the thing with New York Mayor Michael Bloomberg was held to discuss the future of towers 2 and 3. A solution was not found, because both parties their views would not leave. Michael Bloomberg was, however, known that he would put everything in a reasonable solution and ensure that the talks will continue to be maintained. In several New York newspapers Bloomberg said that a longer delay of the World Trade Center reconstruction was unacceptable.
In January 2010 it was agreed by a now begun arbitration proceedings a further period of 45 days, in which there should be more discussion between Silverstein Properties and the Port Authority.
On March 10, 2010, shortly before the deadline, which had set the arbitral tribunal, it was a demonstration of construction workers who were protesting against further delays. They laid down their work on One World Trade Center, World Trade Center Memorial and the fourth tower (which is already built since 2008), to appeal to the Port Authority and Silverstein, to finally agree on a financing concept. Here (German, Rebuilds the WTC at last! ') The workers chanted slogans such as " Build the WTC now!". Both sides gave still known to be ready to talk.
Settlement of the dispute and leases
On 26 March 2010 it was announced that an agreement between the port flange, the city and Silverstein Properties was found. Thus, to begin immediately the construction of Tower 3 (Three World Trade Center or 175 Greenwich Street). Here, by the Port Authority, the City, as made available to the State sufficient funds available that allow both the foundation and the platform of the tower ( about eight above-ground floors comprehensively ) to build. This will take about almost two years to complete. During this time, Silverstein Properties is invited to at least 16 % of the floor space of the tower for rent. If this target is not reached, the work on the Three World Trade Center should be stopped after the establishment of the podium. If, however, until then, at least 16% are under hire is planned, the building fully complete the construction work. At a time schedule for the second, more expensive tower ( the higher Two World Trade Center ), one has for the time being not fixed. Its construction is to begin only after complete recovery of the New York real estate industry. The actual construction started according to official figures in early July 2010.
In January 2013 was officially announced by the owner to Silverstein Properties, the conclusion of a lease agreement with interested parties lie at your fingertips and in contrast to the Two World Trade Center an interruption of the construction works is to be expected. Thus, a completion would not be later than planned in 2015.
Silverstein Properties in July 2013 was finally known that a lease agreement with the company GroupM was closed for Three World Trade Center. The company plans to lease 47,000 sqm of office space in the building, which is expected to further construction rapid completion of the skyscraper. U.S. media spoke of a milestone.

The building site preparation was already 2008. The first foundation foundation work began in July 2010. Beginning of 2011, large amounts of concrete were installed in the foundation, especially for the massive building core inside the tower. In April 2011, a first crane was installed, the second crane was followed in June 2011. In December 2011, the core of the building made of reinforced concrete reached the street level, while the floor area is still a level were below.
