List of megaprojects

From Wikipedia, the free encyclopedia
Jump to: navigation, search

This is a list of megaprojects, i.e., extremely large-scale investment projects. The number of such projects is so large that the list may never be fully completed.


Megaprojects may be defined as:

  • Projects that cost more than US$1 billion and attract a lot of public attention because of substantial impacts on communities, environment, and budgets
  • Projects can also be "initiatives that are physical, very expensive, and public"[1]

Megaprojects require care in the project development process to reduce any possible optimism bias and strategic misrepresentation. Examples of megaprojects include bridges, tunnels, highways, railways, airports, seaports, power plants, dams, wastewater projects, Special Economic Zones (SEZ), oil and natural gas extraction projects, public buildings, information technology systems, aerospace projects, and weapons systems.

This list identifies a wide variety of examples of major historic and contemporary projects that meet one or both megaproject criteria identified above.

Aerospace projects[edit]

Disaster cleanup[edit]

Construction of the new confinement structure for the nuclear reactor that melted down at Chernobyl in Ukraine.
Bags of oily waste are piled up during the cleanup of the Exxon Valdez oil spill in 1989.

While most megaprojects are planned and undertaken with careful forethought, some are undertaken out of necessity after a natural disaster occurs. There have also been a few man-made disasters.
