An Architecture competition initiated by NEXT BIG ONE, the objective of this single-stage open-ideas competition is to propose an innovative design solution that can mitigate natural disasters while simultaneously providing community permanence ; rather than a disaster response or recovery plan.


Tsunami is a natural disaster that can’t be predicted, highplace is a destination point during earthquake that followed the emergence of tsunami. Only in a couple of minutes or seconds were given to us for safe ourselves. To anticipating this disaster is to make Temporary Evacuation Shelter (TES). A place for tsunami evacuation that can be accessed quickly by the surrounding community. In addition, the function of this building can flexibly follow the requirements in the area of space. Accessibility resistance to earthquake or tsunami up during the course of the evacuation process is also an integral series of roles for Temporary Evacuation Shelter (TES).



Based on that issue, Djehovan create 60S, also known as 60 Seconds to Safe. A Temporary Evacuation Shelter for earthquake and tsunami. 60S accommodate the needs of disaster response ranging from Pre Disaster-Disaster-Post Disaster.


  1. Building The Form ; the selection of basic shape is what determines the succeded of Temporary Evacuation Shelter prototype. 60S takes the form of a circle (cylinder) with the following consideration :
    • Symmetric, circle is a shape that is symmetrical. allowing a uniform load distribution
    • Adaptive to site, by not having a dominant side, 60S can be placed without the need for consideration of direction
    • Modular, the basic shape of a circle. The more parts that can be assembled in a modular
    • Strength, pressure from many different direction arising from tsunami helped to reinforce the rigidity between modules
  2. Fabrication Process ; pressing need for the placement of 60S in many critical points tsunami caused production speed is a critical criteria. With the modular concept, the number of part types into fewer making it possible to be mass produced in a short time
  3. Floating Foundation ; tsunami are usually preceded with a high magnitude earthquake, requires 60S is able to survive and ensure the strength to be a safe place. Generally not as earthquake-resistant structures that reinforce and resist thrust earthquake, 60S uses the principle of mass damper by using a floating foundation that followed the earthquake motion and slowly reduce the frequency of vibration. In buildings random tremor can be supressed by the presence of fluid around the foundation
  4. Functional Spaces ; other than as Temporary Evacuation Shelter, the spaces in 60S can be used flexibly in accordance with the requirements. Such as school, meeting hall to health facilities
  5. Upper Structure ; the upper part of the building structure is made rigid by distributing the load equally between inside and outside of the column structure. Overcome the pressure from outside, each module contained in the ramp and life unit distribute and strengthen the unity of the module. While the tensile force of the tsunami caused by beam and sling overcome the bond between the columns
  6. Landscape Support ; on the 60S there is barrel containing soil are planted around the building and used for growing potatoes, which is used as food reserves for emergencies. Landscape around 60S was used as one of the patron during tsunami
  7. Speed Access ; when disaster occurs, 60S can be achieved approximately 60 second until the safety zone. Key of accessibility in 60S is on the ramp slope 1:20, so easily accessible for elderly and disable. Ramp has width 2,4 metres with the aim to facilitate access to large-scale evacuation
  8. Life Unit ; command center of each 60S, there are various kinds of facilities to survive during disaster until post-disaster such as logistic inventory, bathroom, electric generator, water reservoir, kitchen along with other safety equipment. In the worst case, life unit can be removed and floating on the water
