We provide professional tunnel and geotechnical engineering services across all stages of a project, from planning and design to construction support and program management.
We use our experience with Building Information Modeling and digital data management tools to increase collaboration, improve project delivery and simplify asset management.
Our program management services to major infrastructure projects ensure projects are delivered on schedule, within budget and to the highest quality while using state-of-art tunneling technologies.
Whether in dense urban areas or remote alpine environments, GZ's team of experts develops feasibility studies, project options and design concepts to help your project get off to the right start.
Our design experts utilize our decades of international experience to develop state-of-the-art project-specific design solutions for tunnels and underground structures.
GZ's full range of services cover the development of ground investigation programs, on-site supervision of drilling, sampling, and testing, as well as the interpretation of the collected data.
Our staff are experts in developing numerical models that capture the physical phenomena that control the behavior of the construction of underground structures.
We provide a seamless link between design and construction by using strict quality control procedures to ensure correct design implementation and to guarantee a high-quality final product.
Our engineering services are not just performed underground - we use our geotechnical expertise to design stable and long-lasting slope and excavation support systems.
