Abstract: The demand for Rigid Inclusion (RI) systems as a cost-effective solution to support buildings and infrastructure development has grown substantially in North America over the past decade. With this growth, efforts to standardize RI design have become more prevalent. With much of the available literature focusing on design, there is a notable gap in addressing quality control, construction considerations, and use of quality testing during execution.

Recently, the industry has increasingly focused attention to Measurement While Drilling (MWD) data as a tool for quality control of RI installation. While MWD data provides valuable insights into potential non-conformance, not all deviations from expected parameters are indicative of performance issues.

To assess whether non-conformance identified by MWD will impact performance, RI specialty contractors can leverage a variety of available tools, including additional geotechnical exploration, field observations, ASIRI Quality Tests (AQTs), and Thermal Integrity Profiling (TIP) tests. By utilizing this expanded toolbox during installation, practitioners can more effectively evaluate the impact of observed deviations in the MWD data, potentially reducing the need for rework of previously installed elements. A RI project in in Bethlehem, PA serves as an example of these tools in action.
