[1] Torroja's first large project was the Tempul cable-stayed aqueduct (1926) in Guadalete, Jerez de la Frontera, in which he used pre-stressed girders.

[1] The first collaborative work of Torroja and Sanchez Arcas was the pavilion of the Construction Commission of the university city, completed in June 1931.

In 1934 they founded the Instituto Técnico de la Construcción y Edificación (ITCE, Technical Institute of Construction and Building).

[4] Other founding members were the architect Modesto López Otero (1885–1962) and the engineers José María Aguirre Gonzalo (1897–1988) and Alfonso Peña Boeuf (1888–1966).

The Comité Européen du Béton sought to coordinate the research effort on structural concrete in Europe following the end of the Second World War.

Eduardo Torroja designed the thin-shell water tower in Fedala[8] and the roof of the "La Zarzuela" racetrack in Madrid[9] in the form of a hyperboloid.
