Consorzio Stabile Eteria is an Italian industrial consortium established in 2021 to become a major national construction and infrastructure group capable of developing large-scale projects and contributing to the industrial and employment recovery of Italy. It was formed through a strategic alliance between two leading industrial groups, Caltagirone and Gavio, and later expanded to include I.CO.P. S.p.A., enhancing its technical capabilities and sector reach. The consortium’s identity is built on innovation, reliability, and a strong commitment to sustainable infrastructure development, with a diversified portfolio worth around €2.3 billion spanning railway infrastructure, water cycle systems, airport and maritime facilities, road networks, civil and industrial buildings, and social facilities. The combined technical expertise and financial strength of its members position Eteria as a competitive player in public and private markets, focusing on delivering complex civil engineering projects that support Italy’s long-term development and competitiveness.
