1 World Trade Center was redesigned due to security concerns by the NYPD and then-Governor George Pataki. Details such as the 1,776 height and the 276-foot spire remained the same. To comply with safety concerns, 1 World Trade Center would have no occupied space other than the lobby. It was also redesigned to be set back farther from West Street, a heavily trafficked highway. Many of the windows were planned to be tempered, laminated and multilayered for extra protection against explosions. The newly designed base has a smaller footprint and planned to be more of a square than a parallelogram.
The final design of the WTC Memorial and museum was unveiled by Arad and Walker. The design included two large "voids"-cascading reflecting pools thirty feet into the footprints of the Twin Towers. The design allowed visitors to follow ramps angled down the side of each footprint to an underground chamber that allows views. Names of all the victims, including rescuers and those who died in the 1993 Trade Center bombing are inscribed on a wall between the chamber and the pool. Extensive landscaping in the plaza featuring 400 swamp white oak and sweet gum trees will create a canopy over the plaza in the warmer months.

These architects joined an impressive roster of architectural stars working at the site including site master planner Daniel Libeskin; David Childs of SOM designing the Freedom Tower; Santiago Calatrava, the architect for the transit hub; Michael Arad, who with Peter Walker, is responsible for the World Trade Center Memorial and Museum, and Lord Norman Foster for Tower 2. Following the announcement, Silverstein Properties set up a WTC design studio at 7 World Trade Center with architects, engineers, and consultants working together in an unprecedented collaborative spirit on the designs for Towers 2, 3 and 4.
Santiago Calatrava presented the design for the WTC Transportation Hub at the Winter Garden. The design evokes the image of a bird in flight. The building will be build with steel, glass, and light. To bring an even greater sense of open air and natural light to the station's concourse, mezzanine, and platform levels, Calatrava designed the hub's ceiling to retract-an innovative concept used mostly in sports arenas. Each level inside the station was designed to be column-free to create an open, bright space. Through this Transportation Hub, pedestrians will have access to Hudson River ferry terminals, PATH trains, 13 subway lines, and possibly a direct rail link to JFK International Airport. The Hub will be positioned at the northeast corner of the WTC site at Church and Vessey Streets and is expected to form an underground connection between the World Financial Center and the Metropolitan Transportation Authority's Fulton Street Transit Center.
Michael Arad and Peter Walker were selected as the designers of the Memorial ‘Reflecting Absence', honoring those lost in the terrorist attacks of September 11, 2001 and February 26, 1993. 5,201 submissions were received and the World Trade Center Memorial Competition, launched by the LMDC, became the largest design competition in history.
The shimmering skyscraper of glass, steel, and cable would stand at 1,776 feet, invoking the symbolism of the building. The building was designed to sit at the northwest corner of the site. The design also called for 70 commercial stories with 2.6 million square feet of office space, plus an underground regional transportation hub, garages, and several shopping centers. A public observation deck and a rebuilt Windows on the World, the restaurant that once sat atop the north tower was also in the plan. The previous World Trade Center buildings each had 110 stories, but 1 World Trace Center will rise higher because of a large glass structure and 276-foot spire topping off the building.
The station featured a canopy entrance along Church Street and a 118-by-12 foot mosaic mural, "Iridescent Lightning," by Giulio Candussio. The station was also ornamented with opaque panel walls inscribed with inspirational quotes attesting to the resilience of New York City. The panels partially shielded the WTC site from view. Since reopening after 9/11, the station has reclaimed its status as the busiest station in the PATH system.
Architect David Childs of Skidmore, Ownings & Merrill was selected to design 1 World Trade Center, planned to be the tallest of the five new WTC office towers. Mr. Childs is a graduate of Yale College and the Yale School of Art and Architecture. He joined the Washington, DC office of Skidmore, Owings & Merrill in 1971 after having served as the design director of the Pennsylvania Avenue Commission. David Childs then relocated to SOM's New York office where he worked on the New York Mercantile Exchange, the arrivals building at JFK, and Worldwide Plaza, among others. Differences of opinion quickly arose between Libeskind and Childs regarding their visions for the site's final result.
Calatrava is best known for his designs of public buildings and bridges. Some of his more recent work includes the Sundial at Turtle Bay in Redding, California, the James Joyce in Dublin, and the Olympic sports complex in Athens.
The Lower Manhattan Development Corporation announced the start of an international design competition for the WTC Memorial Site to commemorate those lost on September 11th and the 1993 bombings of the World Trade Center.
Libeskind's design was judged based on 12 points of criteria including price, public response, vision, connectivity, public space, and how the victims of the September 11th attacks would be memorialized. 1 World Trade Center is already the most famous element of architect Daniel Libeskind's WTC Master Plan. Libeskind's plan proposed a descending spiral of towers beginning at the site's northwest corner and ending at the National 9/11 Memorial and Museum, where the Twin Towers' footprints will be memorialized.
There were 2,000 entries in total. The seven semifinalists of this round of competition presented their designs at the Winter Garden of the World Financial Center.
Among its many building enhancements, 7 WTC included a reinforced concrete core and a steel superstructure. Safety systems exceeded New York City building code and are expected to form the model for future high-rise building codes. Construction on 7 WTC began soon after in 2002.
New York Governor George Pataki and New Jersey Governor James McGreevey created a World Trade Center site viewing fence with heroes' names and other information panels for visitors. The first steel column was also erected at the WTC site for the temporary PATH station.
The 1st round of the design competition for the reconstruction of the World Trade Center site took place, known as the "Preliminary Design Contest". However, the designs submitted for rebuilding the WTC were criticized as being too boring and placing too much emphasis on office space. This round of the design competition sparked debate about the future of the World Trade Center site.
The Federal Emergency Management issued a report on the collapse of 7 WTC on 9/11 based on a preliminary investigation conducted with the Structural Institute of the American Society of Civil Engineers confirming that the collapse was caused by fires on multiple stories ignited by debris from the other towers. These fires had continued due to lack of water for sprinklers or firefighting.
Beyer Blinder Belle is best known for its restoration of Grand Central Terminal while Parsons Brinkerhoff is one of the oldest U.S. private engineering firms involved in energy, environment and facilities engineering.
The Lower Manhattan Development Corporation was created in the aftermath of September 11th by then-Governor George Pataki and then-Mayor Rudy Giuliani to plan the reconstruction of Lower Manhattan and distribute nearly $10 billion in federal funds aimed toward rebuilding and revitalizing downtown Manhattan. The LMDC sponsored the international design competition for the World Trade Center Memorial. LMDC works in coordination with public and private sectors to coordinate long-term planning for the World Trade Center site and the neighboring downtown communities.
Two commercial jet planes struck the Twin Towers, causing their collapse and the destruction of four other WTC buildings. The attack killed 2,750 people at the Trade Center, many of them emergency responders. The collapse of 7 WTC, which had already been evacuated, followed at 5:20 p.m. that day due to a fire in the building. Soon after the attacks, Larry Silverstein announced his intent to rebuild.
Larry Silverstein completed the largest real estate transaction in New York history by acquiring the World Trade Center for $3.2 billion, only to see it destroyed six weeks later in the terrorist attacks on 9/11. Previously, the World Trade Center site was under the control of the Port Authority of New York & New Jersey. In this picture Larry Silverstein is joined by his children, Roger Silverstein and Lisa Silverstein, his wife, Klara Silverstein, and his attorney, Leonard Boxer.
Their goal was to knock the north tower into the south tower, bringing both towers down and killing thousands of people. The attack killed six people, including a pregnant woman, injured more than 1,000 people and created a five-story hole beneath the towers, resulting in hundreds of millions of dollars of damage.
The 610 foot 7 WTC was designed by Emery Roth & Sons with a red granite façade and a trapezoidal footprint. To supply power to the 10048 zip code, which was dedicated solely to the WTC site, Con Edison built an electrical substation located below 7 WTC in 1967. Tishman Realty & Construction managed construction of the building, which began in 1983. Some of the major tenants at 7 WTC were Salomon Smith Barney, American Express Bank International, ITT Hartford Insurance Group and Standard Chartered Bank.
Developed by Joe Baum and initially designed by Warren Platner, it occupied 50,000 square feet of space and offered breathtaking views of Manhattan. In its last year of operation (2000), Windows on the World reported its revenue as $37 million, making it the highest-grossing restaurant in the United States.
The Top of the World Observation Deck opens at Two World Trade Center (South Tower) on the 107th floor providing breathtaking views of Manhattan. On a clear day, visitors could see up to 50 miles in any direction.
A fire broke out on the 11th floor of the north tower. The fire then spread from the 9th to 14th floors by igniting the insulation of telephone cables in a utility shaft that ran between the floors. Most of the damage was concentrated on the 11th floor. Fireproofing protected the steel from melting and there was no structural damage to the tower.
The 24-year-old Petit made eight total crossings between the mostly finished towers, a quarter mile above the sidewalks of Manhattan, in an unexpected event that lasted about 45 minutes. Philippe Petit's high-wire walk is credited with bringing much needed popular attention and fondness to the Twin Towers.
The twin towers debut as the tallest buildings in the world -at 1,368 and 1,362 feet and 110 stories each-- surpassing the height of the Empire State Building until the Sears Tower in Chicago, providing 10 million sq ft of office space was built. The ceremonial opening of the twin towers on this date marked seven years of construction, preceded by more than a decade's worth of planning that transformed 16 acres of Lower Manhattan into an international business hub. In addition to the twin towers, four smaller buildings and a hotel, all built nearby around a central landscaped plaza, completed the complex. The mall at the World Trade Center, which was located immediately below the plaza, was the largest shopping mall in lower Manhattan. The six basements housed two subway stations and a stop on the PATH trains to New Jersey. Some 50,000 people worked in the buildings, while another 200,000 visited or passed through each day.
Some of the tenants in this building included Morgan Stanley; Verizon Communication; Thacher, Proffitt & Wood; New York Stock Exchange; Keefe, Bruyette & Woods; Fiduciary Trust Company International; and Dow Jones and Company.
The topping out ceremony of the north tower took place. The first tenants moved into the north tower, 1 WTC, although the tower was not fully completed until 1972. 1 WTC featured many innovations masterminded by Yamasaki and his team. Among them were the Twin Towers' high-speed elevators, sky lobbies, and "hollow tube" building model that distributed weight from the inner core across floor trusses to the exterior's closely spaced steel columns. The load-bearing exterior also served to brace against wind. Some of the major tenants at 1 WTC included Marsh USA INC, Bank of America, Cantor Fitzgerald Securities, and Brown & Wood LLP.
Demolition at the site began with the clearance of thirteen square blocks of low rise buildings for constru ction of the World Trade Center. Groundbreaking for the construction began on August 5, 1966. Site preparations were vast and included an elaborate method of foundation work for which a "bathtub" had to be built 65 feet below grade. The bathtub was made of a bentonite (absorbent clay) slurry wall intended to keep out groundwater and the Hudson River. Tie-backs were inserted through the wall and anchored at an angle in the earth behind them. WTC 1, the North Tower, rose ahead of WTC 2.
The design consisted of a square plan approximately 207 feet in dimension on each side. The buildings were designed with narrow office windows 18 inches wide, due to Yamasaki's fear of heights and his desire to make building tenants feel secure. The building facades were covered in aluminum-alloy.
Minoru Yamasaki was selected to design the project. Yamasaki was a second generation Japanese-American who studied architecture at the University of Washington and New York University. Yamasaki's designs often paid tribute to classical themes but his use of modern technology resulted in contemporary structures of glass and concrete. Yamasaki considered hundreds of different building configurations before deciding on the twin towers design and worked closely with the selected structural engineers of the project, Worthington, Skilling Helle and Jackson. Worthington, Skilling Helle and Jackson developed a tube-frame structural system which allowed for open floor plans without columns in the office spaces. Less than two years and more than 100 design concepts later, the Port Authority unveiled the $525 million World Trade Center plan to the public. It was a composite of six buildings comprised of 10 million square feet of office space. At its core were the Twin Towers, which at 110 stories (1,368 and 1,362 feet) each would be the world's tallest skyscrapers. Public sentiment ranged from astonishment at the sheer size of the towers, to both thrill and dismay at their monolithic, contemporary design.
SOM proposed a complete rebuilding and expansion of the financial district: the narrow streets would be closed while others would be widened, traffic would be redistributed and over 100 blocks razed. Various features of the SOM plan were implemented such as a Civic Center east of City Hall and a large marina on the East River that prefaced the South Street Seaport. SOM also suggested a World Trade Center. In 1958, Chase Manhattan Bank vice chair David Rockefeller announced plans to build a multi-million-square-foot complex on Lower Manhattan's east side. The Port Authority of New York and New Jersey agreed to oversee the building project.
The original proposal was for only one 70-story building, not the final twin towers design. Winthrop Aldrich, chairman of Chase Bank, was appointed to explore the feasibility of the project. The New York State Legislature passed a bill authorizing Thomas E. Dewey to begin developing plans for the project.
