Africarium-Oceanarium in the Wroclaw-based ZOO The construction of the Wroclaw-based Africarium-Oceanarium started in spring 2012. The new structure will comprise a large pavilion having the length of 160 m and width of more than 50 m, with its main building reaching the height of approx. 15 m. The investment will be worth around PLN 350 million. Inter- System S.A. from Wroclaw became the general contractor, while ULMA Construccion Polska SA was the main supplier of formworks and scaffoldings. The new structure will be divided into thematic sections. Animals from different regions of Africa will be on separate exhibitions. The largest attraction of the Oceanarium will be constituted by an acrylic glass tunnel where everyone will be able to “watch furtively” the oceanic world. One of the largest predators – a shark will live in the aquarium. Apart from the shark, the Oceanarium will become home for fish from African lakes and animals living in the Nile basin. The Africarium building was seated on a single-level reinforced concrete slab having the average thickness of 120 cm, which was built with the use of ORMA modular formwork. This system was also used to erect straight reinforced concrete walls, both with pilasters and without them, as well as a conference room of reinforced concrete structure – worth particular attention – which is composed of external inclined walls made with the application of architectural concrete technology. All pools and technical basins of the Africarium, including outdoor pools, were formed in curvilinear geometry as independent structures based on the so- called “white tub” technology. Each pool is an independent load-bearing structure. Basins were made with the use of ORMA and BIRA formworks. BIRA formwork was also applied to erect the remaining circular walls of the building.
