During his long career, Pier Luigi Nervi has explored the potential of concrete through the cast-in place and the prefabrication of elements in reinforced concrete or in ferro-cement, the material he invented and patented during the war. All of his best known works, such as the Berta Stadium, the hangars built in Orivieto, Orbetello and Torre del Lago Puccini, the Halls of the Turin Exposition Center, the Unesco buildings, the Little Sport Palace and the Papal Audience Hall represent an important chapter in the history of architecture, structure and construction of the twentieth century.
The passion of Nervi for the manufacturing process of the concrete and formworks is examined in a systematic manner within the volume. The authors illustrate the creative process put in place by Nervi through the examination of documents never even studied in other essays, unpublished designs, drawings, specifications, photographs of the yards and correspondence with colleagues and collaborators.
