Sweco has been commissioned by Société du Grand Paris for the detailed design work and project management of the maintenance complex for Line 15 East of the Grand Paris Express metro network in Paris, France.

With 200 kilometres of new underground metro lines and 68 new stations, the Grand Paris Express in the French capital is the largest metro project in Europe. The objective is to support urban expansion and make travelling more efficient, reduce traffic, and improve the city´s air quality.

The governmental organization Société du Grand Paris has commissioned Sweco for the detailed design work and project management of the maintenance complex that will support the new Line 15 East metro line, a part of the Grand Paris Express. The line connects suburbs from Saint-Denis Pleyel to Champigny through a new ring line around Paris.

“The maintenance complex for Line 15 East is a significant component of the Grand Paris Express project. We are glad that Société du Grand Paris yet again chooses our expertise and commitment to improve commuting for Paris’ travellers,” said Erwin Malcorps, Managing Director of Sweco Belgium.

The complex will connect with the national railway network and it consists of facilities for depot and infrastructure maintenance. It will also serve as support for the neighbouring lines.

Line 15 East will be opened in stages from 2025 to 2030. Sweco’s work will begin immediately with a partial commission in 2025. The order value for Sweco is approximately SEK 100 million.

In 2016, Sweco was commissioned for overall project management and detailed civil design of Line 17, a new 20-kilometre metro line with five new stations, within the Grand Paris Express project.
