"Strength lies in unity" and for this reason, our companies have decided to join together in a limited liability consortium called IDRA. In Greek mythology, the dragon HYDRA (IDRA) had a single body but many heads; in modern times, the companies of north east Italy have grouped together as one entity known as "CONSORZIO STABILE IDRA BUILDING" and the many heads are represented by the Group's aims to acquire tenders, project financing, concessions for public and private works for the planning, construction and maintenance of building and technological works.
