"The Bathtub" refers to the underground foundation area at the site of the World Trade Center and accompanying buildings in New York City. The term bathtub is something of a misnomer, as the area does not hold any water; rather the purpose of its design is to keep water out. The name is more so used to describe its shape of a deep basin with high walls, like a bathtub.
The original World Trade Center was a large complex of seven buildings in Lower Manhattan, New York City, United States. It featured the landmark Twin Towers, which opened on April 4, 1973 and were destroyed in 2001 during the September 11 attacks. At the time of their completion, the Twin Towers — the original 1 World Trade Center, at 1,368 feet (417 m); and 2 World Trade Center, at 1,362 feet (415.1 m) — were the tallest buildings in the world. Other buildings in the complex included the Marriott World Trade Center, 4 WTC, 5 WTC, 6 WTC, and 7 WTC. The complex was located in New York City's Financial District and contained 13,400,000 square feet (1,240,000 m2) of office space.
The City of New York, usually called either New York City (NYC) or simply New York (NY), is the most populous city in the United States and thus also in the state of New York. With an estimated 2017 population of 8,622,698 distributed over a land area of about 302.6 square miles (784 km2), New York is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, the largest metropolitan area in the world by urban landmass and one of the world's most populous megacities, with an estimated 20,320,876 people in its 2017 Metropolitan Statistical Area and 23,876,155 residents in its Combined Statistical Area. A global power city, New York City has been described as the cultural, financial, and media capital of the world, and exerts a significant impact upon commerce, entertainment, research, technology, education, politics, tourism, art, fashion, and sports. The city's fast pace has inspired the term New York minute. Home to the headquarters of the United Nations, New York is an important center for international diplomacy.
The Bathtub, built in 1967–1968, encompasses a large, roughly rectangular excavation down to bedrock surrounded by reinforced concrete walls, intended to serve as dams to prevent water intrusion from the nearby Hudson River (North River). It enclosed nearly the entire original World Trade Center. 65 feet (20 m) below. Manually removing water from this area would have severely altered the water levels surrounding the World Trade Center site and thus jeopardize the foundations of nearby buildings, causing them to sink. This is why the Bathtub method was used.The World Trade Center site was located on man-made water-clogged landfill that had accumulated over centuries, providing an extension of land out onto the Hudson River from the original Manhattan shoreline, with bedrock located
Earthworks are engineering works created through the processing of parts of the earth's surface involving quantities of soil or unformed rock.
In geology, bedrock is the lithified rock that lies under a loose softer material called regolith at the surface of the Earth or other terrestrial planets. The broken and weathered regolith includes soil and subsoil. The surface of the bedrock beneath the soil cover is known as rockhead in engineering geology, and its identification by digging, drilling or geophysical methods is an important task in most civil engineering projects. Superficial deposits can be extremely thick, such that the bedrock lies hundreds of meters below the surface.
A dam is a barrier that stops or restricts the flow of water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect water or for storage of water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.
The Bathtub contains a 16-acre (65,000 m2) site, including seven basement levels, the downtown terminal of the PATH rapid transit line, and the preexisting New York City Subway's IRT Broadway–Seventh Avenue Line ( 1 train). The South Tower of the World Trade Center was actually built around the PATH tubes that passed through the foundation area, thus service was uninterrupted throughout the whole of the construction period. The waterproof walls were 3 feet (0.91 m) thick and 70 feet (21 m) high.
Port Authority Trans-Hudson (PATH) is a rapid transit system connecting the cities of Newark, Harrison, Hoboken, and Jersey City, in metropolitan northern New Jersey, with the lower and midtown sections of Manhattan in New York City. The PATH is operated by the Port Authority Trans-Hudson Corporation, a wholly owned subsidiary of the Port Authority of New York and New Jersey. PATH trains run 24 hours a day and 7 days a week; four lines operate during the daytime on weekdays, while two lines operate during weekends, late nights, and holidays.
Rapid transit or mass rapid transit (MRT), also known as heavy rail, metro, subway, tube, U-Bahn or underground, is a type of high-capacity public transport generally found in urban areas. Unlike buses or trams, rapid transit systems are electric railways that operate on an exclusive right-of-way, which cannot be accessed by pedestrians or other vehicles of any sort, and which is often grade separated in tunnels or on elevated railways.
The New York City Subway is a rapid transit system owned by the City of New York and leased to the New York City Transit Authority, a subsidiary agency of the state-run Metropolitan Transportation Authority (MTA). Opened in 1904, the New York City Subway is one of the world's oldest public transit systems, one of the world's most used metro systems, and the metro system with the most stations. It offers service 24 hours per day on every day of the year, though some routes may operate only part-time.
The excavated material that was dug up to build the bathtub was again used as landfill to construct Battery Park City, and the same method was also used to construct the foundation area of the Willis Tower in Chicago.
Battery Park City is a mainly residential 92-acre (37 ha) planned community on the west side of the southern tip of the island of Manhattan in New York City. More than one-third of the development is parkland. The land upon which it is built was created by land reclamation on the Hudson River using over 3 million cubic yards of soil and rock excavated during the construction of the World Trade Center, the New York City Water Tunnel, and certain other construction projects, as well as from sand dredged from New York Harbor off Staten Island. The neighborhood, which is the site of Brookfield Place, along with numerous buildings designed for housing, commercial, and retail, is named for adjacent Battery Park.
The Willis Tower, built as and still commonly referred to as the Sears Tower, is a 110-story, 1,450-foot (442.1 m) skyscraper in Chicago, Illinois. At completion in 1973, it surpassed the World Trade Center in New York to become the tallest building in the world, a title it held for nearly 25 years; it remained the tallest building in the Western Hemisphere until the completion of a new building at the rebuilt World Trade Center site in 2014. The building is considered a seminal achievement for architect Fazlur Rahman Khan. The Willis Tower is currently the second-tallest building in the United States and the Western hemisphere – and the 16th-tallest in the world. More than one million people visit its observation deck each year, making it one of Chicago's most popular tourist destinations. The structure was renamed in 2009 by the Willis Group as a term of its lease.
Chicago, officially the City of Chicago, is the most populous city in Illinois and the third most populous city in the United States. As of the 2017 census-estimate, it has a population of 2,716,450, which makes it the most populous city in the Midwestern United States. Chicago is the county seat of Cook County, the second most populous county in the United States, and the principal city of the Chicago metropolitan area, which is often referred to as "Chicagoland." The Chicago metropolitan area, at nearly 10 million people, is the third-largest in the United States, the fourth largest in North America, and the third largest metropolitan area in the world by land area.
There are several penetrations through "The Bathtub" wall: DWV, utility systems, and PATH trains: Today, a passageway leads between Brookfield Place and the World Trade Center Transportation Hub.
Brookfield Place, built as and still commonly referred to as the World Financial Center, is a shopping center and office-building complex located across West Street from the World Trade Center in the Battery Park City neighborhood of Manhattan, New York City. Overlooking the Hudson River, Brookfield Place has been home to offices of various companies including Merrill Lynch, RBC Capital Markets, Nomura Group, American Express, Bank of New York Mellon, Time Inc. and Brookfield Asset Management, among others. In 2014, the complex was given its current name following the completion of extensive renovations.
Once constructed, the bathtub walls relied on the presence of the basement floors of the WTC to give lateral support. When these were partially destroyed following the collapse of the Twin Towers during the September 11 attacks, it was feared that removing the resulting debris pile could weaken the walls and cause them to fail, endangering workers and possibly compromising other buildings and flooding a significant portion of the subway system. During the recovery and clean-up operation, dangerous degradation of the walls was discovered, prompting an emergency operation to install tiebacks to the bedrock to shore up the bathtub walls. 85 feet (26 m) underground.Excavation of a new Bathtub was conducted between 2006 and 2008, with the new Bathtub reaching
The September 11 attacks were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks.
The World Trade Center site, formerly referred to as "Ground Zero" or "the Pile" immediately after the September 11 attacks, is a 14.6-acre (5.9 ha) area in Lower Manhattan in New York City.
