In the relatively short space of time that people have populated the world, we have gone from living in caves and breaking into our dinner with a sharpened stone to creating things so vast and powerful they would make our stone-wielding ancestors’ jaws drop.

Engineering – and with it: effective project management – has been at the forefront of many of the greatest human achievements in history, from the pyramids of Ancient Egypt to the huge and highly complex structures being built across the world today.

We created this infographic not only to highlight seven of the world’s engineering wonders, but also to show you some of the incredible challenges each of them posed from a project management point of view (the most expensive project cost $26 billion, and the lengthiest lasted 33 years!).
