The gas turbine blade manufacturing unit of Siemens Zrt. was realized in Késmárk Street in Budapest. In the project, the designers of our company prepared the permit and construction plans, and we also participated in the tendering process. The implementation consists of 2 phases: the alterations and construction of the new unit were preceded by lengthy demolition work. In both phases, our company was responsible for the construction supervision of the construction works. The project consists of a new hall of 10,000 square meters and an expansion of 2,500 square meters. Collaboration began in September 2016 and ended in 2018.
