The City of Tucson says a fire earlier this week is costing between eight and ten million dollars in damage.
The fire happened near 10th Street and Tyndall on Tuesday at a student housing construction site called "The Mark."
No one was injured, but the fire was so hot that it melted nearby cars.
Officials are still working to learn what exactly started the fire.
