AirBus A380
The Airbus A380 is a double-deck, wide-body, four-engine jet airliner manufactured by the European corporation Airbus, a subsidiary of EADS. It is the world's largest passenger airliner and due to its size, many airports have had to expand their facilities to properly accommodate it. Designed to challenge Boeing's monopoly in the large-aircraft market, the A380 made its maiden flight on 27 April 2005 and entered initial commercial service in October 2007 with Singapore Airlines. The aircraft was known as the Airbus A3XX during much of its development, before receiving the A380 designation.
The A380's upper deck extends along the entire length of the fuselage, with a width equivalent to a wide-body aircraft. This allows for an A380-800's cabin with 478 square meters (5,145.1 sq ft) of floor space; 49% more floor space than the next-largest airliner, the Boeing 747-400 with 321 square meters (3,455.2 sq ft), and provides seating for 525 people in a typical three-class configuration or up to 853 people in all-economy class configurations. The A380-800 has a design range of 15,400 kilometers (8,300 nmi; 9,600 mi), sufficient to fly from New York to Hong Kong, and a cruising speed of Mach 0.85 (about 900 km/h or 560 mph at cruising altitude).
As of February 2012 there had been 253 firm orders for the A380, of which 72 have been delivered. The largest order, for 90 aircraft, was from Emirates.

Millau Viaduct, The World's Tallest Bridge
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. Designed by the French structural engineer Michel Virlogeux and British architect Norman Foster, it is the tallest bridge in the world with one mast's summit at 343.0 metres (1,125 ft) above the base of the structure. It is the 12th highest bridge in the world, at 270 metres (890 ft) high below the road deck. The viaduct is part of the A75-A71 autoroute axis from Paris to Montpellier. Construction cost was approximately €400 million. It was formally dedicated on 14 December 2004, inaugurated the day after and opened to traffic two days later. The bridge received the 2006 IABSE Outstanding Structure Award.
History
Problems with traffic on the route from Paris to Spain along the stretch passing through the valley near the town of Millau, especially during the summer when the roads became jammed with holiday traffic, necessitated the building of a bridge across the valley. The first plans were discussed in 1987 by CETE, and by October 1991 the decision was made to build a high crossing of the Tarn River by a structure of around 2,500 m (8,200 ft). During 1993–1994 there were separate consultations with seven architects and eight structural engineers; and during 1995–1996 there was a second definition study with five associated architect groups and structural engineers. In January 1995 there was a declaration of public interest; and in July 1996 the jury decided in favour of a cable-stayed design with multiple spans, as proposed by the Sogelerg consortium (Michel Virlogeux and Norman Foster). The decision to proceed by grant of contract was made in May 1998; then in June 2000 the contest for the construction contract was launched, open to four consortia. In March 2001 Eiffage established the subsidiary Compagnie Eiffage du Viaduc de Millau (CEVM) and was declared winner of the contest and awarded the prime contract in August.

World's Tallest Building
Burj Khalifa (Arabic: برج خليفة "Khalifa Tower"), known as Burj Dubai prior to its inauguration, is a skyscraper in Dubai, United Arab Emirates, and is the tallest manmade structure in the world, at 829.84 m (2,723 ft). Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009.
The building officially opened on 4 January 2010, and is part of the new 2 km2 (490-acre) flagship development called Downtown Dubai at the 'First Interchange' along Sheikh Zayed Road, near Dubai's main business district. The tower's architecture and engineering were performed by Skidmore, Owings and Merrill of Chicago, with Adrian Smith as chief architect, and Bill Baker as chief structural engineer. The primary contractor was Samsung C&T of South Korea.
The total cost for the project was about US$1.5 billion; and for the entire "Downtown Dubai" development, US$20 billion. In March 2009, Mohamed Ali Alabbar, chairman of the project's developer, Emaar Properties, said office space pricing at Burj Khalifa reached US$4,000 per sq ft (over US$43,000 per m²) and the Armani Residences, also in Burj Khalifa, sold for US$3,500 per sq ft (over US$37,500 per m²).
The project's completion coincided with the global financial crisis of 2007–2010, and with vast overbuilding in the country, led to high vacancies and foreclosures. With Dubai mired in debt from its huge ambitions, the government was forced to seek multibillion dollar bailouts from its oil rich neighbor Abu Dhabi. Subsequently, in a surprise move at its opening ceremony, the tower was renamed Burj Khalifa, said to honour the UAE President Khalifa bin Zayed Al Nahyan for his crucial support.
Due to the slumping demand in Dubai's property market, the rents in the Burj Khalifa plummeted 40% some ten months after its opening. Out of 900 apartments in the tower, around 825 were still empty at that time

Petronas Towers
The Petronas Towers (Malay: Menara Petronas, also known as the Petronas Twin Towers or Menara Berkembar Petronas in Malay) are twin skyscrapers in Kuala Lumpur, Malaysia. According to the CTBUH's official definition and ranking, they were the tallest buildings in the world from 1998 to 2004 until surpassed by Taipei 101, but remain the tallest twin buildings ever built, surpassing the World Trade Center.The building is the landmark of Kuala Lumpur with nearby Kuala Lumpur Tower.
Comparison with other towers
The Petronas Towers were the tallest buildings in the world for six years, until Taipei 101 was completed in 2004. The height of the towers is measured to the top of their structural components such as spires, but do not include antennas. Spires are considered actual integral parts of the architectural design of buildings, to which changes would substantially change the appearance and design of the building, whereas antennas may be added or removed without such consequences. The Petronas Towers still remain the tallest twin buildings in the world.
The Petronas Towers and the Kuala Lumpur Tower dominate the skyline of Kuala Lumpur's Central Business District.
The Petronas's height compared to some other well-known tall structures
Willis Tower (formerly Sears Tower) and the World Trade Center towers were each constructed with 110 occupied floors – 22 more than the 88 floors of the Petronas Towers. Willis Tower’s tallest antenna is 75.41 m (247.4 ft) taller than those of the Petronas Towers, however, in accordance with CTBUH regulations and guidelines, the antennas of Willis Tower were not counted as part of its architectural features.The spires on the Petronas Towers are included in the height since they are not antenna masts. Therefore, the Petronas Towers exceed the official height of Willis Tower by 10 m (33 ft) even though the roof of Petronas Towers (378.6 m) is 63.4 m (208 ft) lower than the roof of Willis Tower (442 m).
History
Designed by Argentine architect César Pelli and Filipino-Malaysian Engineer Deejay Cerico under the consultancy of J. C. Guinto, and Filipino Designer Dominic "Minick" Saibo, the Petronas Towers were completed in 1998 after seven years of construction and became the tallest buildings in the world.They were built on the site of Kuala Lumpur's race

Gotthard Base Tunnel (GBT) - World's Longest Tunnel
The Gotthard Base Tunnel (GBT) is a new railway tunnel beneath the Swiss Alps, expected to open in 2016. With a route length of 57 km (35.4 mi) and a total of 151.84 km (94.3 mi) of tunnels, shafts and passages, it is the world's longest rail tunnel, surpassing the Japanese Seikan Tunnel.
Its main purpose is to increase total transport capacity across the Alps, especially for freight, notably between Germany and Italy, and more particularly to shift freight volumes from road to rail to reduce environmental damage caused by ever-increasing numbers of trucks. A secondary benefit will be to cut the journey time for passenger trains from Zürich to Milan by about an hour and from Zürich to Lugano to 1 hour 40 minutes.
The project consists of two single-track tunnels. It is part of the AlpTransit project, also known as the New Railway Link through the Alps (NRLA), which includes the Lötschberg Base Tunnel between the cantons of Bern and Valais and the under construction (late 2019) Ceneri Base Tunnel to the south. It bypasses the Gotthardbahn, a winding mountain route opened in 1882 across the Saint-Gotthard Massif, which is now operating at capacity, and establishes a direct route usable by high-speed rail and heavy freight trains.
