Integrated Survey and Three-Dimensional Modeling for the Historical-Critical Study of Modern Architecture. The Colonia “IX Maggio” (1934-1937) by Ettore Rossi

The “Colonia per i figli delle Genti del mare ‘IX maggio’” is a summer-camp building realized in L’Aquila in 1937, designed by Ettore Rossi (1894 – 1968). It is related to the experimentation on “social” typologies made in these years on national scale by the fascist social policies. Pagano, in 1937, dedicated to the building an article in “Casabella”. The “Colonia” offers a scheme and a settlement typical of hospital buildings, such as the “Ospedale Civile” in Bolzano (1934) of the same author. Between the end of the Sixties and the beginning of the Seventies of the XX century, the building was modified to become university center. Today it still presents the serious damages caused by the earthquake of 2009. The integrated surveying made by laser-scanning allows the realization of a restitutive complex model of the current state, and of a reconstructive model of the building as it was at its inauguration. According to the volumetric and distributive articulation, the models favor the study and understanding of typological and spatial characteristics of the building. The paper focuses on the use of complex 3-D models for the historical-architectural and typological analysis as well as for the restoration project.
