What iC group does

iC consulenten Ziviltechniker GesmbH, operating as the iC group, is a privately held Austrian engineering consultancy headquartered in Vienna (Schönbrunner Straße 297, 1120 Wien; VAT ATU39727907, Commercial Register FN 137252t). The firm is organised around nine interlinked technical fields — Buildings & Structures, Transport & Mobility, Environment, Technical Building Equipment, Construction & Project Management, Water Management, Geology & Geotechnical Engineering, Tunnelling, and Energy — and delivers integrated civil-engineering services from feasibility through construction supervision. Major project references include the Brenner Base Tunnel (62.7 km Austria-Italy corridor, ongoing since 2009), the ElbX Tunnel within Germany's SuedLink energy-transition programme, the Semmering Base Tunnel, the Koralm Railway, the Curtea-de-Arges Tunnel in Romania, the Austrian Parliament renovation (€352.2m budget), the ALDI SÜD headquarters near Salzburg, and ISTA's Lab7 research buildings.

The company's technical platform centres on BIM-based 3D modelling, point-cloud digitisation for heritage structures, NATM (New Austrian Tunnelling Method) tunnelling expertise, and lifecycle/sustainability tooling including Whole Life Carbon assessment, geothermal and energy simulation, and ÖGNI/DGNB certification support. Operations span 19 countries with offices in six Austrian states plus international locations across Western, Southern, Southeastern, Northern and Eastern Europe, the South Caucasus, and Oceania, supported by an affiliated group that includes Elea iC (Slovenia), flussbau iC (hydraulic engineering), Prause iC (building physics), ACCON (environmental consulting in Germany/Italy/Romania) and Euroakustik (Slovakia).

iC generates revenue through professional-services fees on a project-by-project basis, with no standard rate cards disclosed. Go-to-market is enterprise field sales: direct engagement between senior engineers and directors and public authorities, railway operators, developers and industrial clients, supplemented by thought-leadership activity at industry events (FIDIC workshops, World Tunnelling Congress, Madaster CONNECT, ÖGNI committees) and content marketing via the iC Magazine and LinkedIn. The customer base mixes public infrastructure (ÖBB, BBT SE, EU corridor programmes) with private developers and corporations (ALDI SÜD, ISTA, BUWOG, Verbund, Wien Museum, BOKU). Revenue is not publicly disclosed; pricing is negotiated per project and certifications held include ISO 9001, 14001, 45001 and IEC 17025.
