In this paper, the authors present the procedure of compensation of differential shortening for super-tall buildings by the method of Moving Compensation Optimization (MCO). The MCO method has been studied as well as calculated by computers, and clearly shows its superiority. This method has the minimum number of groups of compensation, the minimized compensation value of each group, and the compensated differential shortening values well controlled within the permissible limits of technical requirements, in comparison with methods of Uniformal Compensation, Moving Averaging Correction method and Optimal Compensation method. This differential shortening compensation procedure will be applied for Lotte Center Hanoi building with 70 floors. The results of the compensation procedure prove the advantages of the method such as the effective flexibility to adjust the compensation plan in the actual construction phase, handling specific arising situations due to actual column shortening during construction sequences.
