Swietelsky

What Swietelsky does

Swietelsky AG is an Austrian, privately-held construction conglomerate founded in 1936 and headquartered in Linz (Edlbacherstraße 10, 4020 Linz). It is the third-largest construction company in Austria and operates across 21 countries with more than 13,000 employees, delivering integrated construction services spanning five core divisions—Hochbau (building construction), Tiefbau (civil engineering), Straßen- und Brückenbau (road and bridge construction), Bahnbau (railway construction), and Tunnelbau (tunnel construction)—plus Spezialkompetenzen (total/general contracting, facade and metal construction, timber and hybrid construction, environmental technology, material testing) and a Digitales Bauen & Innovation line built on BIM, Lean Construction, GIS, and real-time data. The company serves national and regional government infrastructure managers (ASFINAG, PKP PLK, Land Salzburg, Správa železnic), state-owned utilities (VERBUND), and private commercial clients (ATG Entertainment, Flughafen Wien AG, JP Immobilien), with major projects including the €376M A26 Linz highway, a €200M 100 km Polish railway modernization, the Limberg dam raising (+30 GWh energy storage), and the Theater im Prater in Vienna.

The business model is professional-services / project-based revenue generated through competitive public tendering and direct enterprise engagement. Pricing is not publicly disclosed; contracts are awarded individually through procurement processes, with select larger clients using an Early Contractor Involvement (ECI) model where Swietelsky is engaged during the concept phase. Geographic revenue concentration is heavy in Austria (~55%), followed by Germany (~15%), Czech Republic (~12%), and Hungary (~4%) in FY 2024/25, with total construction output of €3.67 billion. Swietelsky self-performs most work via 20+ wholly-owned subsidiaries, retains a proprietary heavy-equipment fleet (including a 219-tonne custom Liebherr crane for the Limberg dam) and its own railway transport company (RTS - Rail Transport Service GmbH), and maintains full ISO certification (9001, 14001, 27001, 37001, 37301, 45001) plus SBTi commitment and UN Global Compact adherence to satisfy public-procurement ESG requirements. Leadership comprises CEO Peter Krammer (also COO Railway Construction), CFO Harald Gindl, COO International Klaus Bleckenwegner, and—effective April 1, 2026—COO Austria Wolfgang Pacher.
