Grand Paris Express - Line 15 South

The construction of the Grand Paris Express Line 15 South is one of the largest transport infrastructure projects in Europe. As the first section of the future 75 km orbital line around Paris, this new route connects Pont de Sèvres to Noisy-Champs over 33 km, serves 16 stations across 22 municipalities, and strengthens connections with the entire Île-de-France transport network.

‍

Entering service in 2027, the line will permanently transform travel in the Île-de-France region. It will reduce the travel time between Pont de Sèvres and Noisy-Champs to just 37 minutes, compared to over an hour previously, while improving access to major employment, higher education, and healthcare hubs, such as the Gustave-Roussy Institute, UPEC in Créteil, and the Descartes Campus. Thanks to its numerous connections with metro, RER, tram, and Transilien lines, it will help streamline travel for hundreds of thousands of passengers.

To support this large-scale project, Mezzoteam provided a Common Data Environment (CDE) to centralize documents, secure exchanges, and facilitate collaboration among all stakeholders throughout the construction process.
