Project overview
Stuttgart 21 is one of Europe's most complex transport infrastructure projects — transforming a terminus station into a through-station with 57 km of new tunnels and 8 new stations. The project's scale and complexity demanded BIM coordination from design through to commissioning.
What made this project complex
The project required demolition, new construction, and renovation work within an active rail environment. Coordination between new tunnel infrastructure and existing urban utilities — gas, water, sewage, and telecommunications — presented enormous spatial challenges.
How BIM coordination delivered
Existing utility networks were modelled from survey data and integrated into the project BIM model. New tunnel alignments and station structures were designed against this utility baseline, with automated clash detection ensuring zero conflicts with critical services.
Measurable outcomes
Modelled existing utility networks across entire project corridor
Achieved zero critical utility strikes during tunnelling
Coordinated 8 station models to consistent LOD 350 standard
Enabled real-time progress tracking through BIM-linked schedules
