Officials say three construction workers were injured when part of an upper floor collapsed inside the historic federal courthouse in Savannah, Georgia. Fire Battalion Chief Wayne Ifill says all three workers were taken to a hospital after part of the third floor fell in Tuesday afternoon. None were seriously injured. Everyone else inside the courthouse got out safely. The federal courthouse was built in 1899 in the heart of Savannah's downtown historic district. The building has been undergoing extensive renovations for more than a year and Ifill says the interior has been all but gutted. No courthouse personnel were inside.
