Taking into account the earthquake-resistant design standards in effect when the building was designed, new earthquake-resistant design criteria were established for the retrofit, to check the earthquake-resistant safety of the retrofit design. Structural and functional considerations led to a choice of laminated rubber for the isolator material. The results of vibration analysis using a mass system model demonstrated that the earthquake motion input into the building would be reduced substantially by the retrofitwork. It was also shown that the work would substantially meet the earthquake-resistant design criteria. Three-dimensional vibration analysis was also carried out using a solid frame model to calculate the margin of safety of each structural member would be earthquake-resistant.

The seismic isolation retrofit of the main building of the National Museum of Western Art required excavating the foundation ground under the existent building and installing isolation devices beneath the existing footings. Before the installation of isolation devices, it was necessary to construct piles beneath the existing footings in order to support the weight of the building temporarily during excavation process. The piles were made of steel pipe segments, and were driven by oil jacks utilizing the weight of the building for reaction force. During the retrofitting process, the subsidence of the building supported by the piles were monitored and controlled to avoid causing damage to the superstructure.
