This study is part of the research field on the evolution of Italian construction techniques in the twentieth century. It refers to the contribution made by building companies to construction history through the study of the methods they used. The present work builds and expands on studies done so far by the author as part of his PhD investigating the Italian activity of Sogene (the construction company of Società Generale Immobiliare, SGI) referring to industrialized construction techniques for residential buildings, from the 1950s to the 1970s. Considering the vast activity of the company, use of these techniques can be studied for other purposes. In the 1950s, SGI-Sogene experimented building site mechanization and on site prefabrication (it built the Velasca and Galfa towers in Milan); from the 1960s to the 1970s, Sogene used heavy prefabrication of large concrete panels (the French Estiot system) and prefabrication components (it is the owner of the S70 construction method) for residential building complexes. This study highlights the work of Sogene in the construction of some bridges of the Autostrada del Sole during the so-called Italian economic miracle. Subsequently, this paper focuses on a serial construction method for bridges patented by the construction company and engineer Fabrizio De Miranda: it refers to the mixed steel-concrete system of which De Miranda is an expert. Moreover, this study provides a further contribution to a reconstruction of SGI-Sogene’s overall enterprises highlighting connections between Sogene and some professionals of the Italian School of structural engineering. Ultimately this study aims to improve knowledge about the company and – more generally – investigates the relationships between Italian construction companies in new industrialization processes during the 1960s.

Abstract
This study is part of the research field on the evolution of Italian construction techniques in the twentieth century. It refers to the contribution made by building companies to construction history through the study of the methods they used. The present work builds and expands on studies done so far by the author as part of his PhD investigating the Italian activity of Sogene (the construction company of Società Generale Immobiliare, SGI) referring to industrialized construction techniques for residential buildings, from the 1950s to the 1970s. Considering the vast activity of the company, use of these techniques can be studied for other purposes. In the 1950s, SGI-Sogene experimented building site mechanization and on site prefabrication (it built the Velasca and Galfa towers in Milan); from the 1960s to the 1970s, Sogene used heavy prefabrication of large concrete panels (the French Estiot system) and prefabrication components (it is the owner of the S70 construction method) for residential building complexes. This study highlights the work of Sogene in the construction of some bridges of the Autostrada del Sole during the so-called Italian economic miracle. Subsequently, this paper focuses on a serial construction method for bridges patented by the construction company and engineer Fabrizio De Miranda: it refers to the mixed steel-concrete system of which De Miranda is an expert. Moreover, this study provides a further contribution to a reconstruction of SGI-Sogene’s overall enterprises highlighting connections between Sogene and some professionals of the Italian School of structural engineering.
