Structures

Underground structures: natural and artificial tunnels, subways and related stations. Reinforced concrete structures and retaining walls. Roads tracing.

Structural design is carried out with a view of geotechnical aspects in all Civil Engineering fields, with the capability of following the development of a project from the FEED to the detailed design phase. Our design approach privileges the optimisation of costs and construction schedules with respect to the Contractor’s requirements.

Despite SOIL’s strong geotechnical background, we are able to provide comprehensive structural design services, with special reference to the following areas:

• transportation infrastructures: railways, highways, roads. Our capabilities span from the study of layout, including geological issues, to structural design.
• civil structures: geotechnical and structural design of steel and reinforced concrete structures, including the detailed study of soil-structure interaction.
• deep excavations and underground works: underground (subway), tunnels, caverns, wells, open-air deep excavations. In this field (constituting the core strength of our structural team), comprehensive engineering services are provided from the study of the pre-existing natural environment to the definition of optimal design solutions from both the technical and economical point of view. Detailed numerical 2- and 3-D Finite Element modelling is often carried out.

Design activities are complemented by technical assistance during construction; when geotechnical works are concerned the calculation assumptions are checked by real-time monitoring of the stress-strain behaviour of the soil-structure complex.
