Three World Trade Center

Three World Trade Center (also known as 175 Greenwich Street) is a skyscraper under construction as part of the rebuilding of the World Trade Center site in Lower Manhattan, New York City. The project lies on the east side of Greenwich Street, across the street from the previous location of the Twin Towers, which were destroyed during the September 11 attacks in 2001. Pritzker Prize-winning architect Richard Rogers, of Rogers Stirk Harbour + Partners, was awarded the contract to design the building, which will have a height of 1,079 ft (329 m) tall with 80 stories.As of October 2013, its below-grade foundations are complete, and several floors have been built above street level. The building is slated to be completed in 2018.

Marriott World Trade Center was previously located at the address until its destruction in 2001. It was a hotel building of 22-stories, a steel-frame and 825 rooms. It had a roof height of 242 feet (74 m). Construction began in 1979 and it opened in July 1981 as the Vista International Hotel.

Six World Trade Center

Six World Trade Center was an 8-story building in Lower Manhattan, New York City. The building opened in 1973. It was also the building in the World Trade Center that had the least number of floors. The building served as the U.S. Customs House. It was demolished in 2001 as a result of the September 11th terrorist attacks.

Original building (1973–2001)

Six World Trade Center was first proposed in 1968 together with the World Trade Center site. Construction finished in 1973. The original 6 World Trade Center was home to the US Custom House. It is a 537,693-square-foot (49,953-square-meters), 8-story building in Lower Manhattan, New York City, part of the World Trade Center skyscraper family. It was also the building in the World Trade Center that had the fewest floors, (the building had 8 floors). From the Austin J. Tobin Plaza level, on which the main structure was built, it had a height of 92 feet (28 m) but was 105 feet (32 m) above the actual ground level. It was demolished following the destruction of the World Trade Center, during the September 11 attacks in 2001.

Five World Trade Center

Five World Trade Center (also referred to as 130 Liberty Street) is a planned skyscraper at the World Trade Center in Lower Manhattan, New York City. The site is across Liberty Street, to the south of the main 16-acre (6.5 ha) World Trade Center site. The project is currently on standby while the Port Authority explores a potential sale of the lot to a developer and also finds tenants to occupy the skyscraper. The proposed building shares its name with the original 5 World Trade Center, which was heavily damaged during the collapse of the North Tower and was later demolished. The Port Authority has no plans to construct a building at 130 Liberty Street, although it is open to future development of the site as office, retail, hotel, residential or some mix of those uses.

In June 2007, JPMorgan Chase announced plans to develop the building as the headquarters of its J.P. Morgan investment bank. However, JPMorgan Chase's acquisition of Bear Stearns in March 2008 put those plans in doubt, given the company will relocate J.P. Morgan to 383 Madison Avenue.

International trade

International trade is the exchange of capital, goods, and services across international borders or territories, which could involve the activities of the government and individual. In most countries, such trade represents a significant share of gross domestic product (GDP). While international trade has been present throughout much of history (see Uttarapatha, Silk Road, Amber Road, salt road), its economic, social, and political importance has been on the rise in recent centuries. It is the presupposition of international trade that a sufficient level of geopolitical peace and stability are prevailing in order to allow for the peaceful exchange of trade and commerce to take place between nations.

Trading globally gives consumers and countries the opportunity to be exposed to new markets and products. Almost every kind of product can be found on the international market: food, clothes, spare parts, oil, jewelry, wine, stocks, currencies and water. Services are also traded: tourism, banking, consulting and transportation. A product that is sold to the global market is an export, and a product that is bought from the global market is an import. Imports and exports are accounted for in a country's current account in the balance of payments.

7 World Trade Center

7 World Trade Center is a building in the World Trade Center complex in Lower Manhattan, New York City. The current incarnation is the second building to bear that name and address in that location. The original structure was completed in 1987 and was destroyed in the September 11 attacks. The current building opened in 2006. Both buildings were developed by Larry Silverstein, who holds a ground lease for the site from the Port Authority of New York and New Jersey.

The original 7 World Trade Center was 47 stories tall, clad in red exterior masonry, and occupied a trapezoidal footprint. An elevated walkway connected the building to the World Trade Center plaza. The building was situated above a Consolidated Edison power substation, which imposed unique structural design constraints. When the building opened in 1987, Silverstein had difficulties attracting tenants. In 1988, Salomon Brothers signed a long-term lease, and became the main tenants of the building. On September 11, 2001, 7 WTC was damaged by debris when the nearby North Tower of the World Trade Center collapsed. The debris also ignited fires, which continued to burn throughout the afternoon on lower floors of the building. The building's internal fire suppression system lacked water pressure to fight the fires, and the building collapsed completely at 5:21:10 pm, according to FEMA, while the 2008 NIST study placed the final collapse time at 5:20:52 pm. The collapse began when a critical internal column buckled and triggered structural failure throughout, which was first visible from the exterior with the crumbling of a rooftop penthouse structure at 5:20:33 pm. The collapse made the old 7 World Trade Center the first tall building known to have collapsed primarily due to uncontrolled fires, and the only steel skyscraper in the world to have collapsed due to fire.
