In the transport and hydraulics sector, there are many projects for building, extending or modernising the infrastructure. Our engineers are expert in all the techniques involved in the design, calculation and supervision of all types of civil engineering project.

The solutions offered by our experts encompass a variety of technical, economic, aesthetic and environmental criteria.
They give priority to the durability of the works and their safety for users, but also ensure they fit into their surroundings.

Our company has gained a reputation in the field of engineering structures based on a number of prestigious projects.

Some of these projects have won awards in various competitions organised by the profession.
 
 
















This portal bridge of mixed structure spanning the A13 motorway was a winner in the 2003 steel construction competition


In addition to these prestigious projects, we also work on the design and construction of more day-to-day structures.

In the hydraulic sector, our civil engineering activities have included the construction and modernisation of hydraulic works, such as dams, treatment plants, sewers and reservoirs.

This work involves identification, general design, structural design, outline and detailed design (static calculations, construction drawings), and also assistance to the owner, site supervision and survey of existing structures.

Frisange Interchange (A13, G.D. Luxembourg) is an example of successful integration into the countryside with minimum nuisance for the natural habitat (350 m cut-and-cover under the roundabout at the top of the slip roads) Model of the Pulvermuhle Viaduct, winner of the international competition: the project involved doubling the viaduct dating from 1850 in a protected site within Luxembourg City. TR-Engineering opted for a triangular spatial tubular structure, emphasising its transparency and modernity This 2800 mm diameter man-accessible rainwater drain will be covered with 30m of fill as part of the extension to the parking areas for planes at Luxembourg Airport
