iC was nominated for the 2025 State Prize for Engineering Consulting for its geotechnical 3D modelling of the Yusufeli Dam in north-eastern Turkey. The award ceremony took place on 23 October 2025 at the ERSTE Campus in Vienna. The project demonstrates how digital models can contribute to better planning and control of complex construction processes.
Challenging engineering project in the mountains
At a height of 275 metres, the Yusufeli Dam is the highest arch dam in the world outside China. It is located in a tectonically active mountainous region with challenging geological conditions. Extensive analyses and digital tools were therefore required to ensure safe implementation.
Digital models as a control instrument
The project focused on 3D modelling of the building site and geotechnical structures. This served as a digital tool for planning and ongoing monitoring of the construction phases. By integrating extensive geological data into a model, complex subsoil conditions could be visualised, potential risks identified and decisions in planning and construction specifically supported.
Cooperation and international dimension
The project was commissioned by the Turkish client LIMAK. iC supported the project throughout the entire construction period with geological and geotechnical consulting, 3D modelling and the design of slope stabilisation measures, tunnels and caverns. LIMAK was represented by members of its executive board at the award ceremony in Vienna – a sign of successful international cooperation.
Austrian engineering expertise in the spotlight
The State Prize for Engineering Consulting is awarded by the Federal Ministry for Economic Affairs, Energy and Tourism in conjunction with the Federal Chamber of Civil Engineers, the Professional Association of Engineering Offices and the ACA – Austrian Consultants Association. The State Prize honours projects that impress with their innovative approaches, sustainable planning and international significance.
The Yusufeli project also stands for the special commitment of our team: We would like to congratulate Johannes Kleberger, Jonas Weil, Irmina Pöschl, Waltraud Genser, Oliver Stauber and Georg Hatzenbichler on their well-deserved recognition.
