The 5 Most Important Mega Construction Projects in the World



Typically defined as “projects characterised by: large investment commitment, vast complexity and long-lasting impact” mega construction projects often have the potential to have a transformative impact on every level of a society.

Infrastructure projects in particular can have a lasting, positive impact upon the economy of a nation-state. Take the Panama Canal for example, which is responsible for a significant proportion of Panama’s GDP.

Hit hard by the global economic crisis of 2008 the infrastructure and construction industry is now experiencing a renaissance with many analysts predicting that construction is likely to be one of the most dynamic industrial sectors over the next 15 years.

According to one major report, the volume of construction output will grow by 85% to $15.5 trillion worldwide by 2030. The three biggest players in this volume growth are set to be China, the US and India.

Given the huge role that the construction industry will play in the global economy in the next decade and a half, and the positive impact this will have on engineering job markets, Fircroft’s Infrastructure & Construction team have picked out what they consider to be the 5 most important mega construction projects in the world. In drawing up the list they have taken many factors into consideration including economic, social and cultural impact as well the engineering ambition and technical prowess involved in each project.
