Architect Paulo Mendes da Rocha installed a construction lift, arranged to go up and down constantly, on the Mill's railway yard. The counterpoint of rails raised to horizontals refers to the city's verticality. In São Paulo, there are 1.600 km of lifts, while the train and subway tracks add 250 km.

The presence of this ordinary apparatus of construction, placed close to the building, tries to turn visible in other ways devices that exist in the urban life's routine. It makes one notice the city in its mechanical dimension.
