The BHTS was the deepest soft ground tunnel station in North America at that time.
We were part of this project and succesfully supported our customer, the Dr. G. Sauer Corporation, during the Construction Management of Sequential Excavation Method (SEM/NATM) with Best Practices in Hazard & Risk Assessments, Process/Safety Reviews (PSR’s) in situ and a project-specific risk assessment of ground support for pocket excavation.
