The formwork specialist Doka from Amstetten is involved in the construction of a monumental water storage tank in Vienna, whose dimensions are comparable to St. Stephen's Cathedral. The project underscores the company's technical expertise in complex infrastructure construction with high requirements for watertightness and static load capacity. Large-volume water storage tanks require specialized formwork systems that enable precise concrete pouring while maintaining short cycle times. The construction project is part of Vienna's water supply infrastructure.
