Freedom Tower

After the choice, practically all these unique features have been removed from the updated designs in favor of a more simplified monolithic structure, putting into doubt whether or not the public would have chosen this new design had it been the one originally presented. The builder claims that the bridge's lifetime will be at least 120 years. Some critics have noted that the initial choice for this design of the Freedom Tower was based on the elaborate latticework, the vertical gardens, and an otherwise unique shape after all the other design contenders were eliminated for being too unoriginal. The project required about 127,000 m³ of concrete, 19,000 metric tons of steel for the reinforced concrete, and 5,000 metric tons of pre-stressed concrete for the cables and shrouds. As of the latest design, there appears to be no attempt to integrate either concept into the tower. However, if the concession is very profitable, the French government can assume control of the bridge in 2044. In the original Memory Foundations proposal, the Freedom Tower was to include a vertical garden memorial known as "Gardens of the World." This idea appeared to have been rejected on the basis of a lack of rentable value, and the gardens were replaced in the intermediate design by the wind turbines and latticework that proved to be less popular. The builders, Eiffage, financed the construction in return for a concession to collect the tolls for 75 years, until 2080.

It was most widely criticized for its immense latticework which many observed to look rather skeletal. The bridge's construction costs amount to €394 million, with a toll plaza 6 km north of the viaduct costing an additional €20 million. That intermediate design was probably the least popular of the three designs and appeared to be a predictable shortcoming that should have been foreseeable from such a compromise between diametrically opposed visions for the trade center site. The engineering group Setec has authority in the project, with SNCF engineering having partial control. The latticework concept was actually a compromise between the Memory Foundations architect Liebeskind and Childs, who is largely responsible for the final redesign. The construction consortium is made up of the Eiffage TP company for the concrete part, the Eiffel company for the steel roadway (Gustave Eiffel built the Garabit viaduct in 1884, a train bridge in the neighboring Cantal département), and the Enerpac company for the roadway's hydraulic supports. Before the empty frame of latticework entered the picture, an earlier design of the site, called Memory Foundations, was fairly well received in public opinion. The work leader is the Compagnie Eiffage du Viaduc de Millau, owner of the government contract.

Some believe that the businessman Donald Trump has planned a reconstruction of the twin towers on another place in New York City. Four consortia were in competition for the building contract:. Many of them believe the absence of the iconic Twin Towers creates an ongoing emotional wound that can only be healed by rebuilding the towers as they looked before, as tall or taller. He worked together with the Dutch engineering firm ARCADIS, responsible for the technical design of the bridge. These critics saw replacing two towers with a single, shorter tower would be inappropriately humbling and contrary to the proud nature of New York and the United States, even as a symbolic retreat in the face of terrorism. The architects of the bridge are the British firm Foster and Partners. Other Freedom Tower opponents saw the previously-proposed latticework and antenna on top of the tower to be a mask of the reality that the tower's inhabited stories were to have been fewer than the Twin Towers, and in this way would therefore have been shorter than its predecessors. The original concept for the bridge was devised by French designer Michel Virlogeux.

There have also been accusations of corruption on the part of New York Governor George Pataki, using his influence to get the winning architect's bid picked as a personal favor for a close friend [4]. After the choice of the high viaduct's path, five teams of architects and researchers simultaneously worked on a technical solution. Additionally, some architects contend that a taller building should have been considered, suggesting that for reasons of cost and engineering, taller buildings may actually be safer. After long construction studies, the low solution was abandoned because it would have intersected the water table, had negative effects on the town, cost more, and the driving distance would have been longer. The redesigned tower is set to have 82 floors, more than the initial limit, but still far fewer than various comparable towers (even the much shorter Empire State Building has 102). It consisted of two possibilities: the high solution, and the low solution, requiring the construction of a 200 m bridge to cross the Tarn, then a viaduct of 2300 m extended by a tunnel on the Larzac side. The floor limit was imposed by Silverstein, who expressed concern that higher floors would be a liability in a major accident or terrorist attack. The fourth option was selected by the government on June 28, 1989.

The design of the Freedom Tower has generated some controversy due to the limited number of floors (a maximum of 70) that were designated for office space and other amenities. In initial studies, four options were examined:. Some of the tenants of the World Trade Center are expected to return to the site in the Freedom Tower, including a new Windows on the World, which was formerly on the 106th floor of One World Trade Center. The viaduct was officially inaugurated by President Chirac on December 14, 2004 to open for traffic on December 16, several weeks ahead of the revised schedule. The master planner of the World Trade Center site is architect Daniel Libeskind of Studio Daniel Libeskind, although David Childs of Skidmore, Owings and Merrill, an architect hired by Silverstein, has largely supplanted Libeskind as architect of the Freedom Tower itself. A revised schedule aimed for the bridge to be opened in January 2005. The Port Authority plans to occupy at least one-third of the office space, but no private-sector tenants have yet been found. Construction began on October 10, 2001 and was intended to take 3 years, but weather conditions put work on the bridge behind schedule.

The Port Authority estimates the Freedom Tower to cost US$1.5 to 2 billion alone, or about $675/ft² ($7300/m²). The Royal Gorge Bridge in Colorado, United States has a deck considerably higher than either, at 321 m (1,053 ft) above the Arkansas River. However, the Port Authority of New York and New Jersey owns the 16 acre (65 000 m²) site the tower occupies. Its deck, at "almost 270 m" (886 ft) above the Tarn, is apparently slightly higher than the New River Gorge Bridge in West Virginia in the United States, which is 267 m (876 ft) above the New River. Larry Silverstein of Silverstein Properties, the leaseholder and developer of the complex, is the probable owner of the Freedom Tower when completed. The Millau Viaduct is the second highest vehicular bridge measured from the roadway elevation. The height of the Freedom Tower will probably not be increased before completion, due to the symbolism of having an exact height of 1,776 feet (541 m). Current plans call for towers 382.6 m high.

Emaar, the builders of the Burj Dubai tower, are keeping the final height of their building secret, but speculation is that it will surpass all existing structures at a height of over 2,300 feet (700 m) when it is finished in 2008, two years before the Freedom Tower. The proposed Strait of Messina Bridge in Italy, if constructed would be taller still and would also be the world's largest suspension bridge. If the spire and antenna height (the criteria of the Council on Tall Buildings and Urban Habitat) are included, the Freedom Tower might, when completed, qualify as the tallest office building in the world, if no other rival towers are completed first. The viaduct is the tallest vehicular bridge in the world, nearly twice as tall as the previous tallest vehicular bridge in Europe, the Europabrücke in Austria. Union Square Phase 7 and the Shanghai World Financial Center will have roofs and floors higher than Freedom Tower's highest roofs and floors. The piers were assembled first, together with some temporary supports, before the decks were slid out across the piers by satellite-guided hydraulic rams that moved the deck 600 mm (23.6 inches) every 4 minutes. The Sears Tower, Taipei 101, and other buildings currently have occupied floors higher than the Freedom Tower. The piers each support 97 m (319 ft) tall pylons.

Though not occupied by office space, the Freedom Tower's observation deck is set to be higher, at about 1,362 feet (415 m). These sections were assembled on site from pieces of 60 metric tons, 4 m (13 ft) wide and 17 m (56 ft) long, made in factories in Lauterbourg and Fos-sur-Mer by Eiffage. The World Trade Center's North Tower featured an occupied floor at 1355 feet (413 m). Each pier is composed of 16 framework sections, each section weighing 2,230 metric tons. It is unique, yet it subtly recalls, in the sky, the tragedy that has happened here." [3]. The piers range in height from 77–246 m (253–807 ft), and taper in their longitudinal section from 24.5 m (81 ft) at the base to 11 m (36 ft) at the deck. The building is simpler, architecturally. It carries two lanes of traffic in each direction.

"It is a rare moment when new is better," said Design Partner David Childs, "I feel better about this than the original. The roadway has a slope of 3% descending from south to north, and curves in plan section on a 20 km (12.4 mile) radius to give drivers better visibility. The new redesign much more closely resembles the character of the previous towers than did the original plans. The six central spans each measure 342 m (1,122 ft) with the two outer spans measuring 204 m (670 ft). Above the first 150 to 200 feet (50 to 60 m), the redesign may be as much a result of popular opinion and dissatisfaction in New York City with the previous design, or perhaps the growing popularity of the Twin Towers 2 movement, as with the concerns of safety. The roadway weighs 36,000 metric tons and is 2,460 m (8,071 ft) long, measuring 32 m (105 ft) wide by 4.2 m (13.8 ft) deep. Upon the redesign, announced and revealed on June 29, 2005, the upper building design did actually change, and significantly. The Millau Viaduct consists of an eight-span steel roadway supported by seven concrete piers.

As of May 2005, no structural steel had been ordered. The bridge was constructed by the Eiffage group, which also built the Eiffel Tower, under a government contract which allows the company to collect tolls for up to 75 years. [2] The redesign is said to entail a smaller ground footprint, and it is not known if this means office space in the building will be reduced, or upper floors will be made larger or more numerous to compensate. The Eiffage group operates the viaduct as a toll bridge, with the toll currently set at €4.90 for light automobiles (€6.50 during the peak months of July and August). "The building itself, except for the first 150 to 200 vertical feet (46–60 m), will be the same," said Port Authority Vice President Charles Gargano. Many tourists heading to southern France and Spain follow this route because it is direct and without tolls for the 340 km between Clermont-Ferrand to Béziers, except for the bridge itself. In May 2005, it was announced that a redesign was being done to provide for security from ground level bombs. The purpose of the A75 is to increase the speed and reduce the cost of vehicle traffic travelling along this route.

People involved in the rebuilding effort say that the revisions that need to be made to the site's most prominent feature, the Freedom Tower, could delay the start of construction from several months to a year." [1]. The bridge forms the last link of the A75 (la Méridienne) autoroute, providing a continuous high-speed route south from Paris through Clermont-Ferrand to Béziers. Security concerns outlined in April 2005 by the New York Police Department "have set off a serious reassessment of plans for the World Trade Center site. The bridge now traverses the Tarn valley above its lowest point, linking the causse du Larzac to the causse rouge, and is inside the perimeter of the Grands Causses regional natural park. New York City is a suitable place to set such a light pointing towards the sky without complaints of light pollution by astronomers, as the night sky in locations near New York City is already far too bright for serious astronomical observations. Before the bridge was constructed, traffic had to descend into the Tarn River valley and pass along the route nationale N9 near the town of Millau, causing heavy congestion at the beginning and end of the July and August vacation season. Also atop the spire will be an intense beam of light that will be lit at night and will likely be visible over a thousand feet (300 m) into the air above the tower. .

On top of the spire, the antenna may, pending design finalization, be the new broadcasting system to various New York television channels and radio stations, replacing the antenna on top of the North Tower of the former World Trade Center complex.
. Although the roof area of any tower is comparatively limited, the building will implement a greywater recycling scheme involving rainwater collection. It was formally opened on 14 December 2004 and opened to traffic on 16 December 2004. This will benefit internal daylight propagation; however, at this stage it is unclear how the corresponding issue of solar heat gain will be addressed. Designed by British architect Lord Foster in collaboration with French bridge engineer Michel Virlogeux, it is the tallest vehicular bridge in the world, with one pier's summit at 341 metres (1,118 ft)—slightly higher than the Eiffel Tower and only 40 m (132 ft) shorter than the Empire State Building. "Ultra-clear" glass, as opposed to reflective or tinted glass, is proposed for the fenestration generally. The Millau Viaduct (French: le Viaduc de Millau) is a cable-stayed road bridge that spans the valley of the River Tarn near Millau in southern France.

The windows on the side of the building facing in this direction will be equipped with specially tempered blast-resistant plastic, which will look nearly exactly the same as the glass used in the other sides of the building. [1]. At its closest point, West Street will be 65 feet (20 m) away. Felix Baumgartner became the first person to BASE jump from the bridge on 27 June 2004, shortly after the road deck was completed but well before the bridge was opened. The building will no longer be 25 feet (7.6 m) away from West Street—with the redesign and smaller base (the same width and length now as each of the previous towers), the Freedom Tower will average 90 feet (27 m) away from the street. 2080: Eiffage toll concession runs out. Other new safety features will include 3 foot (90 cm) thick walls for all stairwells, elevator shafts, risers, and sprinkler systems; extremely wide "emergency stairs"; a dedicated set of stairwells exclusively for the use of firefighters; and biological and chemical filters throughout its ventilation system. 2044: French government can assume control of the bridge if the toll concession is very profitable.

Interlocking reflective sheets of these materials along the facade will illuminate in turn as the sun moves across the sky above it. January 10, 2005: initial planned opening date. The exterior of this base will be encased in reflective sheet metal cladding, likely stainless steel and titanium. December 16, 2004: opening of the viaduct, ahead of schedule. The next 120 feet (37 m) immediately upward will also lack windows, containing only mechanical floors to fill out the massive cubic base of the building. December 14, 2004: official inauguration. However, owing to security concerns, the first 30 feet (9 m) up will now lack windows and will rely instead on artificial lighting and openings from 30 to 80 feet (9 to 24 m) high to illuminate the area. 2nd half of 2004: installation of the pylons and shrouds, removal of the temporary roadway supports.

Like the World Trade Center, there will be a large public lobby, with 80 foot (24 m) ceilings, and a restaurant. May 28, 2004: the pieces of roadway are several centimeters apart, their juncture to be accomplished within two weeks. This will be higher than the destroyed Twin Towers observation deck, and also slightly higher than the observation Skydeck of the Sears Tower in Chicago. November 2003: completion of the last piers (Piers P2 at 221 m and P3 at 245 m are the highest piers in the world.). Instead of 1100 feet (335 m), the new deck will allow views from 1362 feet (415 m), the ceiling height of the previous Tower Two. February 25–February 26, 2003: laying of first pieces of roadway. Because there will no longer be a frame of latticework above the habitable space, the observation deck will now be higher than the previous design. November 2002: first piers complete.

The turbines were expected to generate 20% of the building's power. September 2002: assembly of roadway begins. The latticework would have constituted nearly 30% of the building's height. August 2002: start of work on pier support C0. Wind turbines are generally not suited for urban environments because of turbulence created by other nearby buildings; however, the singular height of the proposed tower would have presented a unique opportunity in this context. July 2002: start of work on the foundations of temporary, height adjustable roadway supports. The Freedom Tower will not have the "skeletal frame" of latticework and wind turbines: these have been abandoned. June 2002: support C8 completed, start of work on piers.

There will now be a central spire drawing from precedents such as the Empire State Building and the Chrysler Building rather than an off-center spire intended to echo the Statue of Liberty. March 2002: start of work on the pier support C8. The Freedom Tower will now consist of simple symmetries and a more traditional design intended to bear comparison with selected elements of the existing New York skyline. January 2002: laying pier foundations. Many remaining vestiges of the concepts drawn from the 2002 competition have been discarded. December 14, 2001: laying of the first stone. . October 16, 2001: work begins.

The building is projected to be ready for occupancy in 2010. 1998: decision to contract out both construction costs and future tolls to a private enterprise. It is projected that steel for the building will be visible above ground in 2007, with a topping out in 2009. July 9, 1996: choice of the cable-stayed bridge type. Construction on below-grade utility relocations, footings, and foundations for the Freedom Tower is scheduled to begin in the first quarter of 2006, four and a half years after the World Trade Center's destruction and three and a half years after The Pentagon was completely reconstructed. term). The walls at the base are offset 45 degrees from the walls of the highest floor with interlocking triangle facades. January 10, 1995: declaration of utilité publique (public usefulness), as needed to apply eminent domain(U.S.

Depending on which angle the building is viewed from, the Freedom Tower is designed to appear as either a rectangular shape like both of the previous towers, or as a massive obelisk design. October 19, 1991: selection of the high solution, with the viaduct at 2500 m. However a project for a tower in Chicago, Fordham Spire, is expected to be taller and constructed as early as 2009. June 28, 1989: governmental approval of the middle route. The height of the Freedom Tower is intended to surpass the Sears Tower to become the tallest building in the United States, and to be among the tallest buildings in the world when completed. €4.90–6.50: typical automobile toll, as of 2005. The height to the top of the spire is set to be 1776 feet (541 m), symbolizing the year 1776, when the United States issued its Declaration of Independence. 10,000–25,000 vehicles: estimated daily traffic.

The tower will be located in the northwest corner of the 16 acre (65,000 m²) World Trade Center site, bounded by Vesey Street, West Street, Washington Street and Fulton Street in Lower Manhattan, New York City. 290,000 metric tons: total weight of the bridge. A revised design for the tower was formally unveiled on June 29, 2005, to satisfy security issues raised by the New York City Police Department in April 2005. 85,000 m³: total volume of concrete used. The Freedom Tower is the name given to the planned centerpiece building of the new World Trade Center complex in New York City, whose predecessors were destroyed in the attacks of September 11, 2001. 32.05 m: width of the roadway. 4.20 m: thickness of the roadway.

270 m: average height of the roadway. 154: number of shrouds. 87 m: height of a pylon. 336 m: height of Pier 2, the tallest (245 m at the roadway's level).

77 m: height of Pier 7, the shortest. 7: number of piers. 2,460 metre: total length of the roadway. the successful bidders, lead by the Eiffage group, product of the Fougerolles-SEA fusion, the third largest French group in public works, and the sixth largest in Europe.
