GEOS studies and supervises the following works:

• tunnels, cut and cover tunnels, shafts and underground structures such as subway stations, railway stations, reservoirs, silos and underground parking lots,
• dams, dykes, hydraulic and power generation structures, water collection, storage and transport facilities,
• development of ecological zones, renaturation of watercourses, fish passes, environmental compliance audits, landfill remediation,
• foundations and retaining structures, road and rail infrastructure, platforms and tracks, bridges and civil and structural Engineering,
• residential, administrative and industrial buildings made of reinforced concrete, metal or mixed construction.

GEOS designs, studies and prepares plans, quotes and consultation dossier for companies and also ensures the planning and site supervision.

The design of structures benefits from the traditional specialties of the company: geotechnics, geomechanics, structural Engineering, materials resistance and hydraulics. The domain of these areas in parallel with civil engineering and building leads to the most suitable and competitive solutions because security is treated consistently without flaws or duplication and the responsibility of the work is not diluted between several stakeholders.
