The 92-metre-high, 22-storey building comprises offices, meeting rooms and three floors of parking space. We took care of the entire package: detailed design, engineering, fabrication, assembly of the steel structure as well as delivery and assembly of the steel decking and hollow-core slabs. In total, there are about 7,500 tonnes of steel in this project. Of the total quantity of steel, 500 tonnes of steel is made of a special and unusual type of steel with high-strength properties Histar 460.
The municipal office is located in the middle of the city centre, which immediately presented the necessary challenge for the logistics part of this project. The building has 22 floors and a ground area of 60,000 m². The North and South Towers are connected by two bridge sections. Given the challenge of keeping the structure stable, we set up a detailed step-by-step plan for the assembly of the building.
