Statement by Krzysztof Bielazik, MSc from Bakkala Consulting Engineers (designers of the structure of the facility) regarding the choice of reinforcing steel:

In the Warsaw Spire project, we consciously used reinforcing steel with high ductility. An important design aspect of high and high-rise buildings is the protection of their structures against a progressive catastrophe, i.e. a threat to the safety of the structure due to the occurrence of unpredictable exceptional actions, such as e.g. an explosion, vehicle impact, etc. Reinforcing steel with high ductility is characterized by an additional reserve of tensile strength in area of its plastic deformation, hence it guarantees greater safety of the structure in the event of such circumstances. Its use is therefore one of the elements of our strategy of protecting the structure against exceptional impacts and eliminating the possibility of such a disaster.
