Bridges link, cross, span. The extend land area and are essential for our mobility.

Bridge design must satisfy resistance, behavior and durability criteria. Moreover, bridges organize or reorganize landscape and must do so in an adapted and suitable way. Bridges are thus designed as art pieces, integrating into a comprehensive structure all the program’s requirements, to create a structure that is both unitary and artistic. Our office has developed its own design and workshop methodology and was the winner of many design competitions for large bridges.

Bridges are designed in close collaboration with the owners.



Buildings occupy a large part of our land area and are of different type: residential buildings, office buildings, factories and exceptional buildings such as schools, train stations, museums and worship places.

The load bearing structures of buildings and their façades are developed to meet the requirements of modern architecture – building the land and in the space – aiming towards modernization of our built environment while preserving the architectural heritage. Project development is done using BIM to promote collaboration between the different actors of the project.

Buildings are developed in collaboration with architects as well as heating, ventilation, sanitary and electrical engineers.


Infrastructures – tunnels, galleries, roads and urban planning – are large scale constructions.

Infrastructure planning demands knowledge in geotechnics, networks, roads, urbanism, security systems, traffic and technical equipment. All this knowledge must thus be consolidated to develop a project meeting all requirements. Managing geometry, planning, soil structure interaction, construction methods, logistics and site organization can all be done within our office.

Infrastructures are developed with project teams grouping various actors.
