This study elaborated the process management and quality control of three typical major isolation retrofit projects in the construction stage of base seismic isolation by migrating the building load entrusted by the temporary pile to seismic isolation devices. About the process management, support ground depth was set as a parameter, the process period including the building area and building load were discussed. In the quality control, the impact on the process was generated by the difference of the vertical displacement of load migration and temporary supporting piles properties. The purpose of this study was to analyze the impact of the construction by applying temporary pile in the construction process of seismic isolation devices.
