In the galleries of Z33, two earth ramming machines compress soil from the Ford site into interlocking earth blocks. These manual devices were originally designed for self-help housing in so-called developing countries and also embraced by practitioners of small-scale ecological self-sufficiency. They enable the direct use of local soil for shelter and road construction. The earth ramming machines connect Z33 to various other production sites and raise the question of how artistic production is tied to a specific place: the machines are meant to be used with local soil, but can be used anywhere in the world. In this respect, Lewitt’s work differs from site-specific art that is made for one place. The Ford site in Genk – which is being redeveloped as a logistics hub—is already connected to numerous other places of economic activity. Lewitt uses this site as raw material to be transformed throughout the exhibition.
