In this realm of historical restitution, one relevant choice has been deciding to use a "large scale". The first challenge is that the buildings, blocks, lots, streets and railways, plazas, public spaces and the rural organization around the city which is found in a variety of diverse sources created by different institutions and sectors and is unknown material, abandoned and seldom used, and therefore subject to deterioration are no longer seen and represented as independent isolated events or reduced to a scale in which the forms disappear, but rather are placed for the first time in a vehicle which can contain them and allows their details and the relationships between the parts and the whole to be understood.
El hallazgo original se encuentra justamente en el hecho de que los edificios, manzanas, predios o parcelas, calles e infraestructuras ferroviarias, plazas, espacios públicos y ordenamiento rural del entorno urbano que se encuentran en fuentes diversas y dispersas, elaboradas por distintas instituciones y sectores, y que, como materiales desconocidos, en parte abandonados y poco utilizados, tienen el peligro de deteriorarse ya no son vistos y representados como hechos aislados independientes o reducidos a un esquematismo en que tienden a desaparecer las formas.
