Strengthening and underpinning projects suffer from outdated design assumptions that inflate costs and compromise performance—are we still ignoring fully coupled 3D SSI? In this GeoStruXer-led webinar series, we challenge conventional geotechnical thinking with real-world case studies and cutting-edge simulations that expose inefficiencies and unlock smarter, cost-effective solutions.

Part 01: The Role of Fully Coupled 3D SSI in Underpinning & Strengthening Projects – Case Studies from the Gulf Countries 

Available On Demand

In the first webinar of this series, we will cover:

  • The Hidden Risks of Relying Solely on Soil Reports.
  • Underpinning Done Right – Key factors to consider when strengthening existing foundations for long-term stability.
  • Designing Isolated Footings with Confidence – What to check to prevent unexpected settlement and failure.
  • Common Mistakes in Foundation Strengthening – Lessons learned from real-world failures and how to avoid them.
  • Fully Coupled 3D SSI in Plaxis – How advanced numerical modelling transforms foundation design and analysis.
  • InSAR for Buildings Monitoring – Using satellite-based deformation tracking to assess historical and semi-real-time settlement.
  • Case Studies from the Gulf Countries.
  • Live Q&A.

Part 02: Field-Measured Heave in London Clay: Insights from 3D FEA and Advanced Constitutive Modeling

Available On Demand

In part 2 of this series, we will cover:

  • Field Measurements and Observations (1968–1989) – Key findings from a 21-year monitoring period of heave progression in an unoccupied basement.
  • Advanced Constitutive Modeling in Plaxis – How Hardening Soil Small Strain (HSs) and Soft Soil (SS) models capture London Clay behavior.
  • 3D FEA Model Calibration and Validation. Comparing field-measured heave with numerical predictions and refining soil parameters.
