The plan is to create a network of six driverless metro lines covering 200 kilometers and 68 stations in the Greater Paris area, the Île-de-France. The project is managed by the Société du Grand Paris (SGP) and the Syndicat des transports d'Île-de-France (STIF).
Europe’s largest infrastructure project
Completion of the project is planned for 2030, but a substantial part of the work must be finished before the 2024 Olympic Games. The Grand Paris Express is one of ten “Grand Paris” projects intended to develop the French capital into a metropolitan area similar to Greater London.
In addition to economic challenges, the construction work also presents environmental challenges. At the UN Climate Change Conference in Paris in 2015, the SGP responded to these challenges by pledging to develop the metropolis into a vibrant, connected city that is also environmentally friendly.
Environmental protection and use of building rubble
The SGP wants to protect and conserve natural resources and reduce environmental pollution in accordance with the Convention on Biological Diversity. It promotes the use of technologies, manufacturing processes and services that aim to use existing resources efficiently. On its construction sites, for example, the SGP requires the use of recycled materials as well as for water and energy consumption to be optimized, construction waste to be recycled and for 70% of the building rubble to be processed.
Disposal of building rubble as part of construction site management has been a key issue for SGP since the project was founded. With a plan to recycle the almost 43 million tonnes that will be produced, the construction of the Grand Paris Express offers French and foreign companies a unique opportunity to promote, develop and implement their own innovative solutions.
With regard to building rubble, these solutions focus on:
- Characterization and traceability of building rubble: Improvement of characterization methods for building rubble, with particular regard to rubble produced by tunnel boring machines, and continuing development of traceability systems.
- Transportation of building rubble: Use of alternative options for road transport. Development or improvement of rail loading/transportation/unloading for the rubble produced by Grand Paris
- Treatment and processing of building rubble: Continuing development of the circular economy in the building sector and provision of innovative methods for processing building rubble to create more recycling opportunities
Business opportunities for Swiss companies
The SGP has formed strong partnerships with private companies known as “majors”: large French and foreign groups of companies that specialize in large construction sites. The SGP is looking for skills, innovation and talent for this gigantic infrastructure project in the following fields:
- Structural and civil engineering
- Railway station construction and design
It places great importance on experience and expertise in tunneling and railway construction, from feasibility studies to the analysis of occupational risks, and is searching above all for innovative solutions to reduce costs at all levels.
Trip to Paris for Swiss SMEs on 13-14 June 2018
In collaboration with the Swiss Business Hub France and the Swiss Embassy, Switzerland Global Enterprise is organizing a meeting with SGP and STIF representatives in Paris on 13 and 14 June 2018 to help interested Swiss companies get acquainted with the project. These two days will give Swiss companies the opportunity to present their products and services and to show off their skills in the areas of construction work, procurement and services.
Swiss cleantech expertise in demand
Extensive experience from the construction of the New Railway Link through the Alps (NRLA) and a pioneering role in the cleantech market have given Switzerland an excellent reputation from which Paris would certainly like to benefit.
