The Collin Group has performed forensic analysis and provided expert testimony in over 100 geotechnical failures over the last 30 years. This includes :

  • Failures of MSE Walls
  • Reinforced and Unreinforced Soil Slopes
  • Soil nail Walls
  • Sheet Pile Walls
  • Aggregate Pier Foundations
  • Sewers
  • Building Settlement
  • Embankments Over Soft Soils
  • Column Supported Embankments
MSE Wall Failure
SRW Wall Failure
Yeager Reinforced Slope Failure
Ruptured reinforcement in RSS failure

The forensic analyses performed by The Collin Group have included the use of relatively new technologies like LIDAR to measure deformations of earth retaining structures. 2D and 3D numerical modeling for assessment of complicated soil-structure interaction and 3D limit equilibrium analysis of reinforced soil slopes with slope configurations that do not lend themselves to conventional 2D analysis.
