Underground structures

setec tpi provides integrated engineering services for underground structures, combining structural engineering, fire safety, ventilation, equipment and operations, to ensure the long-term management of infrastructure.

Underground structures lie at the heart of the major challenges facing regions in terms of mobility, energy and resilience. Their design and operation require a high level of technical expertise, combining structural engineering, fire safety, ventilation, operations, electromechanical equipment and a detailed understanding of risks. 

For over 60 years, setec tpi has been designing, securing and modernising the most complex road, rail, urban and utility tunnels. Our teams are involved throughout the entire infrastructure lifecycle: preliminary studies, project management, aerodynamic calculations, 3D modelling, construction works, major refurbishment, safety upgrades and external inspections.
