Abstract

Quality control in deep foundations is a fundamental aspect for ensuring the safety and durability of structures. In this context, Pile Integrity Testing (PIT) and Dynamic Load Testing (DLT) are consolidated as essential tools for verifying and validating pile performance. The non-destructive PIT test, based on wave propagation, allows for the identification of anomalies in the cross and longitudinal sections of piles, ensuring their structural continuity. The DLT test, for its part, evaluates pile bearing capacity by analyzing force and velocity signals, complemented by numerical modeling that breaks down the contribution of the shaft and tip. This paper presents the theoretical foundations, the field execution methodology, and the criteria for interpreting the results of both tests, in accordance with ASTM standards and national regulations (NSR-10). In addition, the main actions to consider when rejecting piles and alternative reinforcement or redesign options are presented. This study seeks to contribute to the professional practice of civil engineering by providing a technical approach that strengthens the understanding and correct application of these tests in deep foundation projects.
