Instrumented Static Load Testing enhances traditional static load tests by using embedded sensors to measure internal load transfer along the pile shaft and toe. This allows engineers to separate the contributions of shaft friction and end bearing. The method is particularly valuable for complex geotechnical conditions or when precise understanding of load distribution is required.

The test involves installing strain gauges, tell-tales, or extensometers along the pile before concreting. Incremental static loads are applied while monitoring settlement and internal strain distribution. The recorded data enables a detailed analysis of how loads are shared along the shaft and at the pile tip.

The report includes shaft friction profiles, end bearing contribution, load-settlement curves, and engineering interpretations. This advanced testing supports optimized foundation design, efficient pile usage, and ensures structural safety under design loads.
