A project of colossal proportions and incredible complexity.
The scale and the ambition of the Grand Paris Express is vast, and it is widely seen as the project of the century. The ambition was to improve connectivity across the city by building 200km of mainly underground rail and 68 new stations. Working on a project this large in a dense city introduced a wide variety of challenges:
Project coordination
The Grand Paris Express is the biggest infrastructure project in Europe. Turning the plans into reality means managing countless building trades and 1000s of subcontractors. We’re simultaneously managing 300 construction projects while controlling for hazards and collaborating with multiple stakeholders.
Difficult conditions
Tunnelling beneath a dense city and a geological terrain that humans have altered for millennia represented a serious engineering challenge.
Extremely strict schedule
This project has always had an ambitious schedule with major milestones planned between 2022 and 2035. Station Saint Denis Pleyel must be completed in time for the 2024 Paris Olympics.
