Infrastructure | Competences | Gruner AG

Rapid progress, safe arrival

The significance of infrastructure is often only recognized when it is absent, inadequate or environmentally damaging. Together with the necessary energy infrastructure, an efficient, sustainable transport system forms the backbone of every modern economy. Increasing mobility, impending gridlock, urbanization, growing environmental pollution and resource shortages are challenges that need to be overcome.

Switzerland's well-developed infrastructure is one of the reasons for its strong reputation. All the same, there is still a need for action, particularly in terms of maintenance and sustainable development of our infrastructure. Gruner has made and continues to make significant contributions in this area and is committed to providing expert support in the implementation and the supervision of all projects that are entrusted to us.

Every infrastructure project has unique attributes which have to be integrated at the design phase. For Gruner, the infrastructure sector offers the ideal opportunity opportunity to demonstrate our interdisciplinary strengths combined with our innovative approach. We routinely integrate the use of Building Information Modelling (BIM) at the design stage of our projects as well as the use of digital twins in our projects which enable us to provide our clients with a visualization and analysis of their digital infrastructure assets across their entire life cycle.

We deliver sustainable solutions and future-proof facilities that provide reliable mobility while guaranteeing efficient spatial management. Our Clients benefit from expert advice and support in the development and implementation of large- and small-scale infrastructure projects, at local, regional, national and international level, for public and private transport facilities as well as for the supply of electricity, water, district heating and cooling, and gas.

United under a single roof, Gruner's generalists and specialists combined expertise can provide start-to-finish services for complex rail, bridge, road, underground, hydraulic and other civil engineering projects.
