With an architectural height of 220.67 metres, Olszynki Park is setting new standards in Polish high-rise construction. The project takes the lead from the previous record holder, Wrocław’s Sky Tower (212 metres). The exposed building height, construction volume and demanding architecture required anchoring solutions with maximum load-bearing capacity. Mechanical and chemical fastening systems from fischer ensure permanent load transfer in different base materials and reliably protect the building structure against dynamic forces.
„The choice of fastening technology is far more than an execution detail – it is a key safety factor for the entire structure. That is why the companies responsible chose our proven systems, which are used wherever reliability and the consistent implementation of the planning are top priorities.“ says Artur Hoffman, Country Manager of fischer Poland.
Large-scale projects can only succeed through reliable interfaces between manufacturers and installation companies. The executing company Reconal has been working closely with fischer for over a decade. Roman Kotuła, Project Manager at Reconal, reveals: „Two factors are decisive for us when choosing fischer: the high quality of the products and the comprehensive technical support – from installation optimisation to the assistance provided by fischer engineers with complex technical calculations.“ The close integration of both partners made a significant contribution to accelerating work processes and implementing the required quality standards on schedule.
At great heights, enormous wind forces act on the facade. The direction and intensity of the loads vary continuously. Pressure and suction forces place particular stress on the facade elements and the areas between the storeys. Every anchorage must safely transfer these changing horizontal loads into the supporting structure. Faulty fixings pose significant risks to the building structure and the surrounding urban environment. fischer systems provide the required structural safety throughout the entire service life.
Due to the different construction materials used in the structure, two specialised fischer fastening solutions were deployed.
Secure heavy-duty anchoring in reinforced concrete: For load-bearing connections in concrete, those responsible selected the FAZ II Plus bolt anchor. The proven expansion anchor bears the full load immediately after the setting process. Its European Technical Assessments (ETAs) guarantee maximum installation safety. Thanks to numerous diameter variants and anchoring depths, the system adapted flexibly to the structural requirements.
Expansion-pressure-free load transfer in aerated concrete: Due to its porous structure, a chemical system was suitable for aerated concrete. The FIS V Plus universal injection mortar fills the drill hole completely without voids. After curing, the mortar forms a high-strength bond with the construction material. This prevents expansion pressure in the porous base material, protects against edge breakouts and offers high resistance to dynamic loads and vibrations.
In a high-rise building of this scale, there is no room for chance.
Standardised fastening solutions make day-to-day work on the construction site considerably easier. Structured technical documentation, clearly understandable installation instructions and coordinated tools reduced installation effort at Olszynki Park. The installation teams were able to carry out anchorages quickly, flawlessly and in a verifiable manner. This reduced installation times and ensured the large-scale project progressed on schedule.
