At Eiffage we deploy our expertise and know-how in designing and building a wide range of structures
Since 2011, Eiffage has been supporting Canadian authorities and industries in building and maintaining their infrastructure
- Heavy Civil : bridges, tunnels, snowsheds, monuments
These are Infrastructures that require perfect management of quality du to stringent requirements (roads, highways, subway, sewer, streetcar, railways, airports, harbours, etc.).
- Dams and Locks
These are Infrastructures that require staged construction and specialized works (cofferdam, dewatering, grouting, below river bed demolition...).
- Watermain, sewage, waste water, potable water, waste treatment plant, storms basins
These are projects that require a perfect understanding of process equipment requirements and quality of work to deliver watertight concrete structures.
- Energy: power plants, wind mills, solar farms
These are often complex structures with design interfaces between Heavy Civil and process equipment.
- Industrial: construction and maintenance
These are Heavy Civil infrastructures that require agility, ability to fulfill tight schedule commitment, sturdy and accurate construction.
- Specialities: demolition, dismantling, heavy hoisting, jacking, waterproofing, deck finishing
Eiffage in Canada has skilled crews to self perform all specialized works.

Hay River bridge
Hay River bridge
Constructed in 1964 and 1965 respectively, the Hay River Pine Point Road and Railway Bridges are located on Highway 5 between the towns of Hay River and Pine Point in the Northwest Territories. The bridges share pier and abutment substructure support. Bridge construction is challenging in the remote northern parts of Canada owing to access and other logistics, cold climate, and short construction season. The substructure were partially reused and the abandoned rail bridge was used as a detour for the road bridge. The two end spans are 48.62 m through trusses and the middle span is a 68.58 m through truss. Scope of works : Using Engineered Ice bridge access, removal and disposal of the road bridge superstructure. partial demolition and reconstruction of the substructure (highway bridge pier and abutment portions). Fabrication, supply and erection of a new 4 steel girder lines over 3 spans erected from shore with heavy lifts. Construction of the new concrete deck (11 metre wide, 167 metre long) and roadway approach work. New bridge reopened to traffic on November 06, 2019

Hamlet swing bridge
Hamlet swing bridge
Along the Trent-Severn Waterway, the Hamlet Bridge is actually two bridges connected. The swing portion of the bridge, constructed in 1915, is a Warren Truss bridge style and is 60 metres long.

Alex Fraser bridge upgrade
Alex Fraser bridge upgrade
The Alex Fraser Bridge opened in 1986. When the bridge first opened, only four of the six lanes were used for traffic with the two outer lanes reserved for pedestrians and cyclists. In 1987 pedestrians and cyclists were moved to the perimeter of the bridge and 6 lanes were opened to accommodate increased traffic demand. Over 30 years later, the bridge now carries an average of 119,000 vehicles each day. The seventh lane bridge counter-flow and Cliveden Avenue interchange improvement will now meet the growing traffic demand. 3 222 meters of moveable barriers were installed to utilize the additional lane as northbound or southbound depending on the time of day. 4 new dynamic messaging gantry signs have been installed to give commuters a real-time information about crossing delays, electrical work, paving, bike path improvements, drainage upgrades, sidewalk widening, girder strengthening, expansion joint modifications.

Line 14
Underground worksLine 14
As part of the Grand Paris Express project, RATP awarded Eiffage Génie Civil a consortium contract to build lot GC03 of the future line 14 Sud, which will link the Olympiades metro station to Orly airport. The contract, worth €365 million, covers the construction of a 4-kilometer tunnel in the municipalities of Thiais, Rungis, Chevilly-Larue and L'Haÿ-les-Roses. The contract also covers the construction of the civil engineering for three stations: Chevilly "Trois-Communes", M.I.N. Porte de Thiais and Pont de Rungis and three ancillary structures.
The work involves the placement of 110,000 m³ of concrete and the excavation of 520,000 m³ of land requiring the use of a tunnel boring machine. 420 people will be mobilized for the total duration of the worksite.
Line 14 South, 14 kilometers long underground, will benefit more than 260,000 inhabitants of Paris, Val-de-Marne and Essonne. As soon as it enters service, it will offer connections with metro line 7, RER C and tramway 7. It will also be connected with lines 15 South and 18 of the Grand Paris Express. The extension of line 14 to the south will provide a fast link between Paris and Orly airport while serving dense residential areas as well as major centers and facilities in the metropolis, such as Rungis market and the Gustave Roussy Institute.
