Extreme Engineering: Super-Stadium Download -- Discovery Channel Store -- 779959

Extreme Engineering unveils some of the most ambitious architectural plans of our times. Some are theoretical; others are in the works. But each of these modern marvels poses challenges that stretch the definition of what's possible. Watch as jaw-dropping computer animation and first-hand accounts from builders, designers and engineers breathe life into the most extreme construction projects ever conceived.

Arizona Cardinals fans haven't had much reason to cheer in recent years, but that's set to change with the introduction of a state-of-the-art stadium. Filmed before its completion date of August, 2006, the Cards' new nest was set to sport a number of one-of-a-kind features – from the "star-chitect" design by Peter Eisenman to North America's first slide-out tray field to the clever "pie-slice" construction method. But with the project only 65 percent complete, workers must shift into hurry-up mode to wrap up construction in time for next season's opener. Watch as crews lift the retractable roof into place, lay enough power lines to run a small city, install the stadium's unique steel-ribbon outer shell and much more.
