DFW Airport decided to upgrade its Airport People Mover System in order to accommodate new terminals and increased passenger count. The new People Mover will transport people from the farthest terminals in 11 minutes transport time. The cost per day of casting conventional concrete columns with forms and guy wires for the reinforcing is high due to space that would be used on the airport apron. Instead of closing aircraft terminals and gates, the DFW Airport People Mover Team decided to design and build a precast post-tensioned segmental system of columns.
