The Inca's built one of the world's great empires through South America, and a road system so durable that it is still in use in some areas, more than five hundred years after the collapse of their empire.
Arizona State University Eminent Scholar Emeritus Clifford J. Schexnayder believes the Inkans were better builders for their climate than even the Romans.
Schexnayder talks to a group of visiting high school students and explores the engineering feats of the Inkas who built roads and structures that could withstand the severe earthquakes. Built without the use of iron, the wheel or stock animals, the Inka Road represents important milestones in the development of civil engineering knowledge. He says the Inka adapted their structures to the natural environment to preserve harmony with the land.
Schexnayder points out the Inkas perfected engineering concepts that had never occurred to the European world and brought a whole new approach to building bridges. This lecture was sponsored by Brycon Construction.
