Three days after the February 27, 2010 earthquake that struck central Chile, the Extreme Architecture Unit, ARQ-X, under the Architecture Department at Technical University Federico Santa María, proposed a rapid action plan capable of developing in the short term a low cost productive and assemblage geodetic coverage system that would allow to quickly to coordinate equipment, meetings and school activities in the most affected areas. The department-based research on geodetic structures application in different materials and building methods dates from 2000. Within a week, considering the existing knowledge and experience it was possible to carry out a productive workshop with volunteer students, quickly raise funds from the University and foreign collaborators, and develop an efficient productive system that by the end of March, 2010 was working in the affected areas. "This is not housing" was the first warning printed on the geodetic coverage; these structures were not gifts to people, but foldable, movable and storable systems intended to be used in future emergencies. This paper describes the structural scheme, productive process, web distribution, and results achieved by this initiative.
