Quality assurance testing is critical for drilled concrete piles, particularly in wet ground conditions where excavation instability, water seepage, and sloughing can affect pile integrity. Two common testing methods are Thermal Integrity Profiling (TIP) and Crosshole Sonic Logging (CSL), with CSL currently required by Alberta Transportation and Economic Corridors for certain bridge projects. A case study from a highway bridge south of Grande Prairie compared both methods on the same piles, finding that TIP and CSL provide complementary information and can improve quality assurance by identifying construction issues and informing corrective techniques.
