The Director-General of the Department of Disaster Prevention and Mitigation (DDPM) confirms the commercial building has not further subsided despite water leaking into the Purple Line subway tunnel. The USAR THAILAND team is ready with equipment to measure and monitor the building, prepared to act immediately if signs of increased tilt appear.
At 21:15 on 9 July 2026 GMT+7 Mr. Theerapat Kachamat, Director-General of the Department of Disaster Prevention and Mitigation (DDPM), commented on the case of a commercial building subsiding due to water leakage into the Purple Line subway construction tunnel near Wongwian Yai roundabout, stating that although visually the building appears to have subsided more, instrument checks reveal the building remains tilted at 79-80 degrees, the same deviation as recorded the previous evening. However, cracks and fractures still require close monitoring. USAR THAILAND officials are using equipment to measure and monitor the condition alongside engineering techniques.
Meanwhile, the DDPM acts as a supporting unit to the Bangkok Metropolitan Administration (BMA) by employing digital tilt measurement tools that emit warning signals if the building tilts further, enabling officials to intervene immediately. The affected building is currently under renovation and unoccupied. Surrounding private business operators are advised to conduct operations cautiously and await official evacuation orders from the BMA.
