Should special design be catered for in bridge piers upon jacking up of superstructure for installation of bearings in incremental launching method?

Upon the completion of the superstructure launching, bearing shall be installed, installation of bearing required lifting the superstructure using jacks, jacks will lift the superstructure by 5 to 10 mm.

Therefore no need for special design for this process because of the effects of differential settlement is considered and checked in bridges design, however levels shall be checked to confirm that it didn’t deviate from the designed value.
