Rigid Inclusion Quality Control and Performance Verification Using Drilling Parameters: A Streamlined Approach-Video

Video Transcription

Video Summary

Mary Nodine presents a streamlined quality-control method for rigid inclusions using measurement-while-drilling (MWD) data collected during installation. GEI developed the Penetration Resistance Index (PRI), an index of resistance with depth, and the Integrated Resistance Index (IRI), which sums resistance below the neutral axis—the portion of an inclusion that helps resist load. By comparing production-element IRI values with a target derived from load-test results and design requirements, engineers can identify potentially weak elements.<br /><br />Batch-processing software compiles installation logs and generates plots, making it faster to review large projects than inspecting each log individually. The approach treats each inclusion as an exploration probe, helping characterize changing ground conditions and flag softer areas for further investigation. MWD data can also support real-time assessment and potentially guide construction adjustments. The method evaluates soil resistance, however, and does not by itself verify grout quality or other installation issues.
