The vault program at Cal-Earth was an intense and great learning experience. We started from the design of the vault and then as a team we worked our way through the actual realization of the vault. It was very rewarding to see what at the beginning we could just visualize in our mind to become bag after bag a solid vault, a room, a shelter. We learned very important aspects about the managing of such a project, worked out the materials needed and the costs, we put together our ideas, discussed operative strategies, took decisions and then monitor the outcomes of our work. I worked in a team that day after day became as strong as the vault we were building, this unity was on its own an important part of my experience. At the end of the program my body was tired but much more fit than the day I arrived, my soul empowered by the dense knowledge I received and my mind was already calculating, envisioning, pushing forward.
