The World's Most Impressive Megaprojects

with the global population continuing to expand and with our world facing immense challenges from housing to transportation and our use of natural resources super-sized construction projects have begun to proliferate [Music] with eye watering budgets extreme complexity staggering scale and far-reaching impacts these are some of the world's most impressive mega projects [Applause] [Music] as the demand for air travel continues to grow and with the United States preparing to host both the 2026 FIFA World Cup and the 2028 Olympic Games airports across the country from LaGuardia to LAX are undergoing multibillion-dollar overhauls the eight point five billion u.s. dollar upgrade to Chicago's O'Hare International will mark the first comprehensive redevelopment and expansion of the terminal core in the airport's history the master plan will see terminal 5 expanded while terminal 2 will be completely rebuilt becoming a global transfer hub with two satellite concourses adding 280,000 square metres of space and 50 additional gates to the airport to minimize disruption the new comm courses will be built first allowing them to take over operations from terminal 2 when the existing building is demolished work on terminal 5 is scheduled to complete by 2022 and subsequent phases were open in stages up to 2028 [Music] a joint project between 35 nations the ITER formerly known as the International thermonuclear experimental reactor is currently under construction in France once completed the 20 billion US dollar Center will allow scientists to recreate the fusion reactions that take place inside the Sun potentially revolutionizing energy production consisting of three main buildings the project is centered around the tokamak a magnetic chamber that will contain the plasma created when particles are heated to over 150 million degrees Celsius and collided to produce fusion energy construction of the vast building that houses the reactor began in 2013 requiring the development of 10 different types of concrete to shield workers from radiation with more than 60% of the reactor complex already complete work is now underway on the tokamak inside is 337 thousand ton housing chamber the entire complex is due to come online in 2025 [Music] Ethiopia's grande Renaissance dam since alongside Nigeria's Eko Atlantic and Egypt's 58 billion dollar new capital as one of Africa's most impressive mega projects with work first starting back in 2011 the dam will become the continents largest hydroelectric plant generating some 6.45 gigawatts of power when it completes in 2022 standing 155 metres tall and extending almost 1,800 meters across the Blue Nile the main structure is being formed with over 10 million tons of concrete holding back 74 cubic kilometers of water when the reservoir is full while the dam will transform Ethiopia's energy production the project has been marred in controversy since inception 20,000 people were relocated to enable the construction works and many have raised concerns over the project's 4.8 billion u.s. dollar price tag which represents roughly 6 percent of Ethiopia's entire GDP and sought funding diverted away from other much-need energy projects the dam has also reignited an ongoing dispute between Ethiopia and the downstream nations of Sudan and Egypt who see the project as an attempt by the Ethiopian government to gain regional influence since its first bullet train shot onto the world stage in 1964 Japan has pioneered the development of high-speed rail [Music] more competition from Europe and China has seen the title of world's fastest trains move west in recent years the new Chow in concern with its maglev carriages able to reach speeds of 500 kilometers per hour will see Japan reclaim the title despite Tokyo and Nagoya sitting 284 kilometers apart the new line will bring the two cities within 40 minutes of each other set to become one of the shortest routes on the Shinkansen Network 90% of the trackway will run underground and beneath the Japanese Alps reducing the travel distance by over 50 kilometers and saving four point nine billion u.s. dollars over alternative options with the new line set to open in 2027 plans are already underway for an extension to link nagoya with the Sarkar a 30 point five billion u.s. dollar mega project in itself [Music] rising 271 meters above Sydney's emerging Barangaroo districts the 75 story one Barangaroo also known as Crown Sydney will become the city's tallest building designed by Wilkinson air the towers structural form is based around three twisting petals and will contain a casino Australia's first six star hotel and eighty-two luxury apartments overlooking the famous harbour with its form ensuring that no two rooms are the same the tower is clad in over seven thousand unique triangle-shaped panels giving it a crystalline appearance as it rises internally the complex will offer extreme luxury with a spa gym open-air tennis court to rooftop infinity pools and a Michelin star restaurant topping out in November 2019 and due to open in 2021 one Barangaroo is already making its mark on the city skyline if you enjoyed this video I would like to get more from the definitive video channel for construction subscribe to the b1f you [Music]

It must be so hard to get involved with projects like these

The 20,000 people that they are relocating for the dam sounds a lot but it is a fraction of the million or so that China had to relocate when they constructed the Three Gorges Dam. What I am interested in is the political fallout that can happen during a severe drought.

Nice

Yeah, it's cool, but...is it necessary? Does the travel/commerce outweigh all of the environmental costs associated with huge, megalithic structures like this? I just question everything now after going through my resource management and environmental classes.

They should also include Nagpur Mumbai Super Communication Expressway. This project is being Constructed in India. The length of this Expressway is 701 km Greenfield, 3+3 PQC, 150 km/hr design speed.
