Due to swelling ground the Chienbergtunnel had to master extraordinary geotechnical challenges by a series of extraordinary risk mitigation packages.
We have been part of this project and succesfully supported the owner and its stakeholders during the rehabilitation of the unexpected & massive invert uplift with construction inspections, Best Practices in Hazard & Risk Assessments and Process/Safety Reviews (PSR’s) in situ.
