1. The Large Hadron Collider
This is how we finish our list of 10 biggest construction projects in the world. Due to the fact its importance overweighs arguments of all other buildings which seem to fade in comparison. It looked right to end with the LHC. Quora again states it is the biggest, project, and also the biggest machine in the world. True, it is not a building per se, but just remember all those explanations and interviews you have seen on the news. The Large Hadron Collider is basically a 17-mile tunnel which is partially in France, and partially in Switzerland. Still, we can say without any doubt that this is the most powerful tunnel in the whole world.
