We thought it would be interesting to take a look at the top five most expensive construction projects across the world and as a construction professional we hope you find it as interesting as we did.

As we all know construction is one of the most important industries in the world, without it there would be no roads, houses, well let’s face it, there wouldn’t be much. So thanks to skilled construction professionals like you we have some of the most incredible infrastructure and some of the most iconic buildings in the world here in the UK.

Do you have any ideas what the top five most expensive construction projects could be? Remember, think outside the box! When we looked into it we were surprised, but they makes sense. So here they are:

5.  Dubailand - $76bn+

When this project was announced in 2003, it was looked at as one of the most ambitious leisure developments in the world. Construction was started in 2006, however it was halted in 2008 due to financial issues and was then resumed in 2013.

Currently, it has been estimated that Dubailand will open before 2020. If it doesn’t then this could be one of the most expensive construction projects that never finished.

King Abdullah Economic City - $86Bn


4. King Abdullah Economic City - $86Bn

Announced in 2005 by the then King, King Abdullah Economic City is located along the coast of the Red Sea, 100km north of Jeddah, which is the commercial hub of Saudi Arabia.

The city, once finished, will include world-class hotels, luxury villas, a huge airport and some very prestigious universities. It has been predicted that the whole city will be fully complete by 2020.

Kashagan Fields - $116Bn


3. Kashagan Fields - $116Bn

This offshore oil field, in the Caspian Sea was built due to the largest oil discovery in the last 30 years. It has been thought that the site has about 13billion barrels of recoverable reserves of crude oil and work to exctract will commence in 2017.

2. The International Space Station - $150bn

Probably one of the most staggering construction feats of any generation, The International Space Station was a joint effort, both financially and in the construction of the station. The 14 countries involved were US, Russia, Canada, Japan, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, and Switzerland and the total cost was split between all conuntries involved.

The first modules were launched into orbit on 20th November 1998 and the current plan is that the station will be crashed into the ocean in 2020, after 26 years of service. Don't know about you but that seems like a bit of a shame!

1. The US Interstate Highway System - $459bn

So, did you guess that this project was the most expensive construction project in the world? Well if you didn’t, don’t worry because we didn’t think of it as well.

As of 2015 the US Interstate Highway System has cost US taxpayers in the region of $459bn, yep that’s a lot of dollar! The project was started in 1956 and the responsibility of this creation was mainly down to Dwight D.Eisenhower. The idea wasn’t to just help with transportation, Eisenhower proposed this as he thought it was crucial for national defence.

Were any of these projects a surprise? Just incase you were thinking what about UK construction projects, The Channel Tunnel came in at number 10, costing £4.65bn.
