Driven piles are increasingly utilized as foundation elements in challenging geotechnical conditions that have where drilled peers would have been deemed appropriate historically. Predicting driven pile performance and capacity can be daunting task. Unique soil conditions or diversity across the subsurface of a project site can add further challenges to predicting performance. High strain dynamic pile testing provides a fast, effective, and economical quality control tool for the installation of driven piles. This paper describes the application of Pile Driving Analyzer® (PDA) in performance evaluation of driven piles installed in a hard clay ground condition in southern Alberta, Canada. The project site is located in the vicinity of Fort MacLeod, Alberta. Site conditions and pile installation process are described in detail. Pile instrumentation, test procedures, and PDA test results and their relevancy are discussed in detail. Finally, CAse Pile Wave Analysis, performed using CAPWAP® software are discussed comprehensively in order to provide baseline conclusion that can be used in future for analysis of driven piles with similar soil conditions.
