ASCE-GI October Luncheon by Mohamad Hussein, P.E. (GRL) 

Deep Foundations are commonly used to support all types of structures in the varied geotechnical and geologic conditions of Central Florida. They are of three major types: driven piles, auger cast-in-place piles, and drilled shafts. These elements are designed to resist combinations of compression, uplift and lateral loads and to limit settlement. Constructability is an important consideration during design and the contractor’s installation equipment and means and methods have a significant effect on the quality and performance of the foundation. Testing and inspection are integral parts of the design and construction process for verification, quality control, and quality assurance.

This presentation covers frequently used testing methods for the assessments of geotechnical load bearing capacity and structural integrity of deep foundations. It includes wave equation analysis, dynamic pile testing with the Pile Driving Analyzer (PDA), low-strain pile integrity testing (P.I.T.), Cross-hole Sonic Logging (CSL) and Thermal Integrity Profiling (T.I.P.). Principles, application, capabilities and limitations of each method will be discussed and illustrated with data from actual cases.
