Bank of Thailand

The Bank of Thailand building consists of five basements with excavation depth of 15.8 meters and only three stories of super structure. The basement construction was constructed only five meters away from Tewavej Palace and ten meters away from Bangkhunphrom Palace. The damage assessment by means of Finite Element Method (FEM) with simulation of basement construction method was carried out to predict the influence on both palaces.

Finally, the top-down construction method was selected for basement construction with one meter thick and 20 meters long of diaphragm wall which was designed together with the 50 meters long bored pile to support the whole building. The full set of instrumentation was installed at the palaces, diaphragm wall and ground surface for monitoring the field performances during and after basement construction. The construction was completed without any damage or effect to both palaces.
