» About Ariana » History

Having experienced management of several mega-projects nationwide and overseas, Ali Mousavi Rahimi founded Ariana Tunnel Dam Co. in 2007. Since then, the company has grown from a one-man operation into a multimillion dollar heavy civil contractor. Mr. Mousavi continues to serve as Chairman of the Board and the executive manager. We are headquartered in Tehran, but build nationwide and overseas. Other Ariana companies, such as Samanian (consulting engineering co.), Ariana D.T. Co (financing and residential and commercial buildings’ construction), International Ariana (imports and exports) and Tajikan Co. (mining) have been formed to complement Ariana Tunnel Dam Co. in special projects.
Among these companies, we have extensive experience in all aspects of heavy civil construction, including dams, hydropower plants, tunnels, roads, buildings, and special projects. The variety of projects we’ve constructed is from sewage system in crowded central of the Karaj metropolitan in Iran to one of the world’s greatest underground hydropower plants in Rogun Project, Tajikistan. At Ariana Tunnel Dam Co. we enjoy challenges.
