About the engineering office

The civil engineering office DI Jürgen Freller ZT GmbH is a civil engineering firm headquartered in Klagenfurt am Wörthersee with branch offices in Graz and Vienna. Its range of services covers structural design across all project phases – from concept design through permit application and tendering to the execution phase – spanning materials in steel, timber and reinforced concrete construction. Further core services include structural analysis reports, structural dynamics calculations, coordination under the BauKG including the safety and health protection plan, local site supervision and construction management, as well as inspections of existing buildings and bridges. References include building projects such as the FH Klagenfurt, the racking warehouse of MAHLE Filterwerk and OBI St. Marx, bridge structures such as the Wildbrücke Völkermarkt and the Alpe Adria Bridge, as well as the civil engineering works of the Reisseck II pumped-storage power plant for Verbund Hydro Power GmbH. Clients come from power plant construction, building and bridge construction, as well as commercial and residential construction in Austria.
