An Architecture Competition initiated by Dinas Pekerjaan Umum (PU) Jakarta, Indonesia. The aim is to design an efficiently Temporary Evacuation Shelter (TES) for Tsunami.





Tsunami is a natural disaster that cannot be predicted. A wide range of Tsunami’s early warning technology has been applied, evacuation process has been socialized and high spot is the safe point when Tsunami comes. Within minutes or even seconds, we have to reach a safe point. An effort to anticipate the Tsunami disaster is create a Temporary Evacuation Shelter (TES). An evacuation shelter of Tsunami that can be accessed quickly by the surrounding people. Accessibility, resistance to Earthquake and Tsunami are things that must exist on TES. Post-Tsunami conditions until ongoing process of evacuation is also main cycle that is inseparable from the role of TES for the people.



Based on that fact, Djehovan found 4 main keywords to design the most efficiently Temporary Evacuation Shelter (TES), they are :

  1. Speed, 60S also known as 60 seconds to safe is a Temporary Evacuation Shelter which is designed to get people quickly reach a height that is safe and protected from the Tsunami. According to it’s name, the time it takes approximately 60 seconds to reach the safe point in this evacuation shelter.
  2. Modular, 60S presence is needed in a short time and mass produced so it can be built quickly.
  3. Strength, the selection of the form, structure, construction as well as the foundation are vital for the 60S and must be able to survive from Earthquake and Tsunami.
  4. Accessibility, is the key to the success of 60S.

60S is planned to be placed on the south coast of the island of Java, Indonesia. Because this area has tectonic plates and cause potentially huge Earthquake and Tsunami.





One of the innovations which is he successfully invented are Floating Foundation system, using the principle of mass damper and a floating foundation that follows the movement of the earthquake and slowly reduce the frequency of vibration in buildings. Random Earthquake motion (lateral/vertical) can be reduced by the presence of fluid around the foundation. Fluid used is a combination of water that always circulated and liquids with characteristics that cannot mixed with water. Has a high viscosity and the density are heavier than water. This affects the power of mass damping foundation.
