Zagreb Airport

Bouygues Bâtiment International designed and built the new terminal at Zagreb Airport under a 30-year concession contract. The project includes a new 66,000-square-meter terminal and the renovation of 17,000 square meters of existing buildings, all carried out without interrupting airport operations. Equipped with 8 boarding gates, 30 check-in counters, and a capacity of up to 8 million passengers per year, the terminal positions the airport as a strategic hub for Croatia, benefiting Croatia Airlines and its partner airlines. The central passenger hub features a continuous retail corridor that optimizes passenger flow.

The construction of Zagreb Airport involved more than 45,000 prefabricated components and 40 km of underground utility lines to connect the drainage systems to the city’s wastewater treatment plant. The floor structure was constructed using prestressed concrete; the phasing of exterior work, carried out partly at night, ensured that air traffic was not disrupted. Sustainability was a key focus, with the recycling of concrete and asphalt for backfill, the collection of rainwater for restroom use, and the use of titanium concrete to capture CO₂. A pumping station separates and filters stormwater, contributing to the project’s LEED Silver certification.

Under a 30-year concession agreement, Bouygues Bâtiment International led the structuring of the financing alongside its partners ADP and the Marguerite Fund. Upon opening, the airport has a capacity of 5 million passengers per year, expandable to 8 million. Since its delivery, the new hub terminal has seen passenger traffic grow by 7% annually up to 2019.

Bouygues Bâtiment International remains involved in the airport’s development as shareholder of the concession company through its subsidiary Bouygues Construction Airport Concessions.
