The Devon Energy Tower is a 50-story corporate skyscraper in Downtown Oklahoma City. and is tied as the 43rd tallest building in the United States. Construction began in October 2009 and was completed in October 2012. Because this is a modern building, how long can it last in a life after people?
1 Day after people: Power grid fails in the Oklahoma state, because without power the Devon Energy Tower lights go out forever.
150 Years after people: The Devon Energy Tower outlasts most Oklahoma structures. But the Devon Energy Tower is now on the verge of collapsing, but it is not plant life that will bring it down. Oklahoma is the State in what is now Tornado Alley. Most tornadoes can be as strong as the 2011 Joplin Tornado in Oklahoma State. Unfortunately, an F5 tornado hits Oklahoma City. The building's floors weaken and fall as soon as 5 floors fall the Devon Energy Tower collapses leaving its remains for the tornado as it subsides.
