Groundworks (L'Hospitalet de Llobregat) is a work initiated in June 2015, on an empty plot in an abandoned factory in the city of L'Hospitalet de Llobregat, to the inmediate southwest of Barcelona and consisted of making a series of excavations based on some diagrams previously sketched and burying entirely or partially some sculptures and drawings as well as diverse material, objects, and memorabilia. The cavities were excavated 30 cm deep to contain sculptures made of cardboard, pigmented plaster, clay and wood together with burnt wooden planks, textiles, raffia fiber utensils, old newspapers, photographs and drawings, in an area of 40 square meters. These items were completely buried or half-buried for a period of two months leading to an irregular deterioration of the objects caused by environmental factors as well as by the fragility of the materials employed. In September 2015 the objects were unearthed leaving a group of holes on the ground that ressembled an archaeological site or a funerary enclosure. The idea central to this project is to integrate the passing of time and the environmental variations of a particular context into the materials, objects and imagery and to deal with symbolic associations through the arrangement of the objects in space.
