Using Thermal Integrity Profiling for Detecting Defects in Drilled Shafts

Drilled shafts are deep foundations used to support structures with large axial and lateral loads and are constructed by excavating cylindrical shafts into the ground and filling them with concrete. The construction of the drilled shafts relies heavily on good practices from the contractor, engineer, and inspector to produce a quality foundation element. Most installation methods involve blind concreting, so it is difficult to be certain of an intact concrete mass of the intended dimensions. The objective of this project is to evaluate the effectiveness, accuracy, and cost of using Thermal Integrity Profiling versus Cross-Hole Sonic Logging for detecting defects in drilled shafts used in deep foundation construction for Missouri Department of Transportation (MoDOT). MoDOT also wants to evaluate the use of optical fiber-based TIP or other materials/techniques as opposed to the conventional thermal wire-based TIP for detecting defects in drilled shafts. This project will include both laboratory and field investigation.
