I would like to know what is the maximum span length in a curve alignment that is feasible for cast-in-place prestressed box girder bridge.

My other question is do you consider construction methods such as design-bid-build, design-build and CM @Risk through Value Engineering that helps in selecting the type of superstructure for a bridge such as T-beam, Box Girder cast-in-place, box girder cast-in-place prestressed, precast prestressed concrete, steel girder etc.
