Assembly of Stair Tower for Slipform

Assembly of Stair Tower for Slipform

The verticality of the stair tower shall be checked only with a plumb bob. Stair tower shall be checked for verticality at every support location. If any deviation is found it shall be corrected then and there, by adjusting support length. The deviation in verticality shall not be more than 10 mm for every 10 M of height and maximum 50 mm for the overall height.
