The world’s largest construction projects

Construction projects are becoming more and more ambitious with the help of advances in technology and design capabilities. Everyone wants to have the next big project and there is the desire to build even bigger, taller and more expensive structures than those before them. Here at Anderselite, we took a look at some of the largest construction projects of recent times.

Dubai is home to some of the world's most ambitious construction projects and this is no different. When it is completed in 2025, it will have cost around $64 billion to construct and take up an area of 278 square kilometres - the equivalent of three Walt Disney Worlds. The scale of the project is vast and it will consist of theme parks, sports and health facilities, eco-tourism, science areas and hotels. It will include the world's largest hotel, with 6,500 rooms and a huge 10 million square foot shopping mall.

The International Space Station (ISS)
This might not be on earth but it has to be one of the most ambitious projects ever attempted. The ISS will be the largest manned object to be put into space and will take up 1,217 cubic metres. The facility compromises both living and research areas and will be home to astronauts for months at a time. The station is so large that it will eventually be seen from around 90% of the earth's surface with just the naked eye. Overall it has taken the combined effort of 16 countries, five space agencies and around 100,000 people to build the ISS. Once complete it will have cost at least $100 billion.

The Big Dig
The Big Dig project in Boston took over 30 years to complete and was opened in 2003 at a cost of $14 billion. It was one of the most complex projects ever conceived, due in part to the fact that the work had to be carried out without impacting on the traffic flow on the highway above. The tunnels that carry traffic under the city had to be capable of carrying up to four lanes of traffic travelling each way. This was a major feat of engineering as the underground work had to navigate around frozen earth, subway lines and a network of gas, water, electric and phone cables. The work also consisted of replacing the existing river crossing with a new cable-stayed bridge.

Jubail II
This $80 billion plan to expand an area in Saudi Arabia will take 22 years to complete and it is expected to open in 2024. Once it has finished, the project will consist of 100 industrial facilities, an extensive road and rail network and an oil refinery capable of producing 350,000 barrels a day.

Songdo International Business District
This area of Seoul in South Korea will create a whole new urban development. Space in the country is extremely limited, so the work will take place on 1,500 acres of land that have been reclaimed from the sea. It will eventually be home to 60,000 people and the tallest building in the country, as well as 80,000 apartments, 50 million square feet of office space and 10 million square feet of retail units. Completion is expected in 2015/16 and the final cost will be around $40 billion.

Yas Island
This development in Abu Dhabi will consist of a huge mix of tourist and leisure facilities and cost $39 billion. The main landmarks will be a new Formula One racetrack, parts of which will run under the Yas Hotel and Ferrari World Abu Dhabi, which will be the world's largest indoor theme park.

South to North Water Transfer Project
There are huge issues with water shortages for large parts of China's vast population and this $58 billion project is designed to reduce these problems. The north of the country has 50% of the population, but only 20% of the water supply. Once it's finished it will be the largest water diversion project ever completed and will take 48 years. It will consist of 3 water canals, each over 600 miles long, which will take water from three of the country's rivers. The work involves relocating large amounts of the population and there are ongoing issues with flood risks and the quality of the water. It will eventually move 44 billion cubic meters of water a year.

South Valley Development
Egypt has to work around massive issues with utilities in the undeveloped parts of the country. However, as a way of moving people from over populated areas, they embarked on a huge project to make water available in the Sahara. The Mubarak Pump Station was completed in 2003 and is the world's largest pumping station. It takes 25 million cubic meters of water a day from the Nile and pumps it into the 72km long Sheikh Zayed Canal.
