Abstract
Discusses several precast segmental box girder bridges where substantial undesired twists were observed during erection. Comparison of casting yard data and erection measurements indicated the excessive wist problem originated during geometry control in the casting yard. The sensitivity of normal control procedures is illustrated and recommendations for a check procedure to control such twists is given.
