What IUB Engineering does

IUB Engineering AG, operating jointly with IM Maggia Engineering SA under the Engineering Gruppe brand, is a privately held Swiss engineering consulting group headquartered in Bern and Locarno. Founded approximately 50 years ago, the group employs 101-250 people across 12 Swiss office locations and provides multidisciplinary engineering services to federal and cantonal authorities, energy utilities, railway operators, and municipal clients. The service portfolio is organized across technical disciplines — hydropower and hydraulic engineering, underground construction, civil and structural engineering, railway infrastructure, traffic technology and tunnel equipment, telecommunications/FTTH, and automation/IT — supplemented by project management, expert assessments, due diligence, and physical/numerical model testing conducted partly in collaboration with ETH Zurich's VAW Laboratory. The group functions as a total planner (Gesamtplaner), covering projects from feasibility studies and conceptual design through construction supervision and commissioning.

The group's core methodology is Building Information Modelling (BIM), implemented since 2014, using a Single Source of Truth approach across multi-discipline projects with software including Allplan, REVIT, Civil 3D, Solibri, and BIMPlus. Revenue is generated through professional engineering services fees contracted primarily via Swiss public tendering processes for government infrastructure (ASTRA, Swissgrid, SBB/CFF, cantonal authorities) and via direct commissioning from enterprise clients such as Axpo subsidiaries, KW Schächen AG, and EnBAG AG. Landmark project references include the Kraftwerke Linth-Limmern pumped storage plant (1000 MW, CHF 1.8 billion project value), the Sihl flood protection Lake Zurich spillway (CHF 160 million), A8 ASTRA tunnel rehabilitation (CHF 101 million), and the Substation Winkeln 220 kV replacement for Swissgrid (CHF 22 million, 2024-2030). The group has selectively expanded internationally into the Balkans (Albania Fangut hydropower, 65 MW), Turkey, and Georgia, while domestically broadening into FTTH/telecommunications planning and electromechanical systems integration.

Core offering

IUB Engineering AG (together with IM Maggia Engineering SA) provides comprehensive engineering consultancy and total planning services for infrastructure projects in hydropower, underground construction, hydraulic/water engineering, and civil/structural works. The firm delivers end-to-end project services from feasibility studies, design, and BIM-based coordination through construction supervision and commissioning for clients such as Swissgrid AG, ASTRA, SBB/CFF, Kraftwerke Linth-Limmern AG, and cantonal authorities across Switzerland. Services also extend to electromechanical equipment planning, FTTH fiber optic networks, railway infrastructure, automation/IT systems, expert assessments, and physical/numerical model testing in collaboration with ETH Zurich.

Product overview

IUB Engineering AG, together with its parent company IM Maggia Engineering SA, operates as an engineering group offering comprehensive civil engineering and infrastructure consulting services across Switzerland. The portfolio consists of core engineering service lines organized by technical discipline (hydropower/hydraulic engineering, underground construction, civil/structural engineering, railway infrastructure, traffic technology, telecommunications, automation/IT) complemented by project delivery services (BIM-based planning, project management, expert assessments, and numerical analyses). The company functions as a traditional engineering consultancy rather than a software product company, providing services through multidisciplinary teams across multiple Swiss office locations.
