Engineering has been an essential aspect of human civilization since the beginning of time. As humans have continued to advance in their learning and technology, they have developed technologies that are capable of achieving seemingly impossible feats. Throughout history, engineers have successfully executed projects that have defied the odds, and many of these extraordinary feats are still evident today. In this article, we will take a look at the top 10 extreme engineering projects that have defied the most challenging odds.
The International Space Station (ISS) is undoubtedly one of the most remarkable engineering projects ever created. This project was initiated in 1984, and its initial phase began in 1998. The ISS is a massive space station that orbits the earth at a distance of approximately 250 miles above the planet's surface. It was built by five different space agencies, namely NASA, the Russian Space Agency, the European Space Agency, the Japan Aerospace Exploration Agency, and the Canadian Space Agency.
The station is approximately 109 meters in length, has a wingspan of 74 meters, and weighs more than 900,000 pounds. The ISS comprises 16 pressurized modules, and it has around 52 computers, which are interconnected to perform various tasks such as communication, navigation, and maintaining the station's systems.
The Burj Khalifa, located in Dubai, United Arab Emirates, is the tallest building globally and stands at 828 meters tall. The building was designed by Adrian Smith, and its construction began in 2004. The Burj Khalifa is an engineering marvel that defies the odds in terms of height and design elements.
The skyscraper's structure comprises a steel frame surrounded by a concrete core. The foundation of the building extends more than 50 meters below ground level and consists of reinforced concrete columns measuring over 2.5 meters in diameter. The building's shape is inspired by the Hymenocallis flower, and it consists of 163 floors.
The Panama Canal is a 51-mile-long waterway that connects the Atlantic and Pacific Oceans through the Caribbean Sea. The canal was built in the early 1900s to reduce the time and distance taken by ships to travel between the two oceans. The construction of the canal was one of the most extensive engineering projects of the 20th century.
The construction of the canal started in 1904 and took around ten years to complete. The project involved creating a cut through the narrowest point in the Central American isthmus, and it required significant excavation and the creation of locks and dams to enable the safe passage of ships. More than 75,000 people worked on the project, and over 25,000 died due to accidents or diseases during the construction period.
The Millau Viaduct is a cable-stayed bridge that spans the River Tarn in Southern France. The bridge has an incredible length of 2.5 kilometers and a height of 343 meters, making it one of the world's highest bridges. The construction of the bridge began in 2001 and was completed in 2004.
The bridge's design is impressive, comprising seven towers that stand above the bridge's deck. The tallest tower in the bridge stands at 343 meters, which is higher than the Eiffel Tower. The bridge's deck is supported by high-strength steel cables connected to the towers, and it spans over the Tarn River.
The Channel Tunnel, also known as the "Chunnel," is the world's longest undersea tunnel, connecting the United Kingdom to France. The tunnel measures about 31 miles long, and it has an average depth of 40 meters below sea level.
The construction of the tunnel was a massive engineering feat that involved boring through the English Channel seabed. The project was very complex, with geologic challenges, safety considerations, and environmental concerns. The Chunnel was opened in 1994 after six years of construction, and it has three tunnels - two for trains and one emergency tunnel.
The Hong Kong-Zhuhai-Macau Bridge (HZMB) is the world's longest sea-crossing bridge, stretching over 55 kilometers across the Pearl River Delta in China. The bridge was opened in 2018 and took almost ten years and $20 billion to construct.
The construction of the bridge involved complex engineering, as it was built over one of the world's busiest shipping lanes. The bridge comprises three cable-stayed spans, an underwater tunnel, and four artificial islands that serve as ports for the bridge.
The Three Gorges Dam in China is the largest hydroelectric power station globally, and it generates more than 22,500 megawatts of power. The dam is around 2.3 kilometers in length and 185 meters high, and it is built on the Yangtze River.
The construction of the dam was a massive engineering project that took more than 17 years to complete. The dam's wall comprises more than 28 million cubic meters of concrete and was built to withstand earthquakes and floods.
The Akashi Kaikyo Bridge in Japan is the world's longest suspension bridge and stretches over 3.9 kilometers long. The bridge connects Kobe and Awaji Island and was opened in 1998.
The construction of the bridge was a great engineering feat as it had to be built to withstand strong winds, earthquakes, and currents. The bridge's massive cables that support the deck weigh more than 17,000 tons and are composed of seven individual strands.
The Palm Islands are a set of three artificial islands located off the coast of Dubai, United Arab Emirates. The islands were created using 80 million cubic meters of sand deposited and shaped into the form of palm trees, and they are visible from space.
The construction of the Palm Islands was a significant engineering project, requiring the use of large dredging vessels to collect and transfer sand from the seafloor. The islands were meticulously designed and constructed to create an excellent living environment for residents.
The Large Hadron Collider (LHC) is the world's largest particle accelerator that lies 27 kilometers beneath the border between Switzerland and France. The collider is designed to study subatomic particles and was built by the European Organization for Nuclear Research (CERN).
The construction of the collider was a massive engineering project that involved constructing a circular tunnel with a diameter of 27 kilometers. The collider is made up of magnets and vacuum chambers that act to guide and accelerate protons or lead ions around the tunnel at nearly the speed of light.
