Construction Industry's 10 largest Engineering Projects ever
Engineers everywhere are inspired by the article, which gives the tricks to tackle challenges like climate change and the application of new technologies.
Cross-rail in London
Innovative solutions have been pioneered on engineering projects around the globe, including some of the largest at the time. Cross-rail is Europe's biggest project in civil engineering, intending to connect Heathrow Airport, the West End, Canary Wharf, and the City of London. Nine new stations include in the project, and 42 kilometers of new tunnels will build underground.
In construction for more than 30 years, Cross-rail is one of London's most ambitious infrastructure projects. An increased capacity of London's rail system by 10% will relieve congestion on major rail and Tube lines will enable 1.5 million more people to commute to key business districts within 45 minutes.
The Big-Dig in Boston
A project that hails as a major undertaking in construction history, the Big Dig was even more challenging than the Central Artery or Third Harbor Tunnel. Traffic congestion in the city has been a constant problem for years. A plan lies out to alleviate traffic congestion and assist commuters.
Under the city of Boston, a superhighway plus the third tunnel beneath Boston Harbor build beneath an active but aging, six-lane elevated highway while working within complex geology and applying advanced engineering methods. Several controversies have surrounded the construction of this structure, such as the use of unsuitable materials, criminal arrests, cost escalation, leaks, poor execution, etc.
Large Hadrons Collider in the border of France & Switzerland
A particle accelerator the size and power of the large Hadrons Collider is located 100 meters under the Franco-Swiss border. Over 200 engineering companies from around the world contributed to this 28-kilometer laboratory, making it among the biggest and most difficult engineering projects ever undertaken.
As the particles travel through the ring, they travel past superconducting magnets equipped with accelerating structures to boost their energy. The inner tunnel of the ring's ring is the voidest place in the solar system. Scientists will be able to solve more mysteries about the universe as a result of the telescope built by the European Organization for Nuclear Research.
Andasol Solar Planet in Spain
Solar power station Andasol is the largest in the world, located in Andalusia. There are over 600,000 mirrors scattered over 126 acres of land in the plant. This system stores solar energy in tanks of molten salt to continue generating electricity without the sun. Solar radiation converts into heat energy, which uses to generate power.
Solar power plants with parabolic troughs are the first in Europe. From this plant, solar power supplies to approximately 450,000 people in Spain. Dry-cooling systems are also used at Andasol plants to save on water consumption.
Eko Atlantic City in Nigeria
A city designed to hold 25 million people are building in Lagos, where there are currently many ongoing construction projects. Creating a unique ocean-front city is the vision of Eko Atlantic City, which restores land engulfed by the sea. This residential and commercial property development will transform Lagos into a city-state, alleviating the city's overpopulation and exhausting infrastructure. A large number of marinas, shopping centers, and office buildings will be built in the supposedly Eko Atlantic City.
T30 Hotel in China
Located in Xiangyin County, the T30 hotel completes in just 360 hours. A new structural system uses to construct the 30-story 5-star hotel, which constructs using prefabrication techniques. Also, the building's energy efficiency is five times better than others in its region, and its waste generation is much less.
A 9.0 Richter earthquake will also not be a problem for the structure. In addition to substantially lowering building costs, higher-quality insulation and other systems use, resulting in dramatically reduced energy demands. Its energy-efficient design, heat recovery system, and state-of-the-art air purification system assure 20 times higher air quality inside the hotel than outside.
The 3 Gorges Dam in China
One of the world's most impressive hydropower projects is the 3 Gorges Dam. Its 32 main turbines design to generate as much electricity as 18 nuclear power plants, and it can withstand a magnitude 7.0 earthquake. The dam is more than 1.3 miles wide and 600 feet tall.
Six months out of the year, it allows cargo ships with a tonnage of 10,000 tons to sail into the interior of China thanks to a reservoir on the Yangtze River basin. The dam contributed to China's economic growth, but it also caused the displacement of more than 1.3 million people; its erosion has caused landslides and caused the destruction of historical sites.
Gotthard Base Tunnel from Switzerland to Italy
Gotthard Base Tunnel opens in 2016, being the largest and deepest underground tunnel ever created. This tunnel, which runs beneath the Alps, will reduce travel times between Zurich, Switzerland, and Milan, Italy while relieving congestion on existing mountain highways and train lines. A cross passage locates every 325 meters between two single-track tubes. The tunnel was built for 14 years by 2,500 workers.

Masdar City in Abu Dhabi
This world-first zero-carbon city is currently under construction in Abu Dhabi. It will highlight renewable energy technology. The city will not allow any automobiles, so public transit and rail will be its main transportation methods, along with existing roads and railways. An array of solar farms has been built in the city to power it. The wind farm and innovative recycling of water will also be part of this project.
The Marmary project in Turkey
An undersea tunnel, suburban railway line improvements along the Gebze-Haydarpasa and Sirkeci-Halkali lines, electrical and mechanical works, as well as the acquisition of new rolling stock make up The Marmary Project. Under the center of Istanbul and the Bosporus Strait, it will have a 13.6-kilometer long tunnel that will connect Europe and Asia.
