Using Geophysics to Assess Geohazards Before Construction: Increase Your Odds for Success!
Understanding subsurface conditions is the key to any successful construction project, including new construction, excavation, and drilling. The consideration and understanding of the subsurface geology...

A Good Cause for a Causeway: How Geotechnology and Project Delivery Restored a Roadway Embankment Crossing a Historically Challenging Soft Ground Site
As part of a Minnesota Department of Transportation (MnDOT) design-build project, a causeway was constructed in 2017 to replace an aging bridge in the southwest metropolitan area of Minneapolis. The causeway...

Poison Oak, Mistakes, And Lessons: Tales of Geofailure Investigations
When things go wrong in geotechnical engineering — like ground movements and earthwork construction delays — failure investigations are often performed. In a typical geotechnical project, the path is relatively...
