Evaluating the Accuracy and Use of Drilled Shaft Integrity Testing Methods in Illinois

The main objective of this project is to provide guidelines for the use of integrity testing for drilled shafts that considers shaft diameter and length, number of drilled shafts to be constructed, soil and rock conditions, expected wet vs. dry method of construction, redundancy of shafts, and importance of the structure. A simple “integrity testing selection” flowchart will be developed to be used by designers for determining the timing, type, and level of integrity testing that should be conducted for a particular structure when drilled shafts are the chosen foundation support.
