The construction site of the 37 million kuna Kaquarium project in Karlovac is sinking

It is hard to believe that the city authorities of Karlovac, led by Mayor Damir Jelić and his deputy Marina Kolaković, could have anticipated that less than a month after marking the ‘first birthday’ of their major project Kaquarium, a freshwater aquarium and river museum, its base part buried in the ground would experience a true ‘water baptism’.

This is not a test of impermeability or similar technical procedures, but the swollen Korana has found an underground path and, aided by abundant rainfall, has flooded this future tourist wonder of Karlovac. It is worth mentioning that it has a contracted pre-estimated value of 36,691,939.28 kuna, of which as much as 98.7 percent is co-financed by non-repayable funds from the EU Regional Development Fund. However, for Mayor Jelić, the flooding of the construction site of the facility, which its advocates insist is being built in the right place right next to the Korana and that it will withstand a water level of 844 cm, almost seems like a desirable and inevitable phase of construction. Almost like in a documentary about the construction of the Jablanica Hydroelectric Power Plant during the raw socialism era.

– Since the Kaquarium facility is not finished, the sinking of this project is currently taking place. Every layman will wonder ‘why are you doing this nonsense, why are you even building it if you are sinking it now?’. I would like to point out that everything is foreseen in the project: since the buoyancy pressures (of the underground waters) are extremely strong, and the construction is not yet finished, there is no other way but that the project anticipated this expected condition and that is why it is sinking. If the project and the facility were completed, then those buoyancy forces could be overcome by the construction itself. Engineers will understand this without any problem, as they managed to explain it to me in two minutes. I reacted as anyone normal would react, but I also warn that the Kaquarium is being built at a level that can fully withstand a water level of 844 cm, and there is also an additional possibility of defense with bags,” said Jelić, adding that the situation is coordinated with the main contractor, AB gradnja, and its partners.
