How are the precast seating units supported?
Designers should verify that the stadia seating units have support on both ends, typically to a precast raker beam. Support must also be provided when large holes are cut into the seating units at mid-span. These openings are commonly required when a recessed camera platform or ADA designated area is needed. Tub seating units will need proper bearing so that they can be set in place, released from the crane line and then connected to the support structure.
