Tom has been an active member of numerous committees for Deep Foundations Institute, ADSC: the International Association of Foundation Drilling, Post Tensioning Institute, and American Society of Civil Engineers.  He has contributed his significant technical knowledge to the advancement of guidance produced by federal agencies and industry groups.  Tom is a member of The Moles, a U.S.-based fraternal organization for the heavy construction industry.  In 2019, Tom was awarded DFI’s Distinguished Service Award, the highest individual honor the association presents, and he served as DFI’s 2021 Traveling Lecturer, presenting case histories to students and engineering societies around the U.S. Tom Richards Lizzi Lecturer Bio 2025

Proposed Modified Davisson Criteria to Evaluate the Ultimate and Safe Service Loads for Micropiles

Originally published in the early 1970s, the Davisson Offset Limit criteria presented a rational procedure to identify the ultimate load observed for driven piles during a compression load test (Davisson 1972).   This lecture presents a method to interpret the load test results from micropiles tested either in compression or tension. Micropiles differ from the driven piles originally analyzed by Davisson. He mainly studied the test results from steel H or pipe piles that were driven using steam or diesel hammers.  Micropiles are typically a drilled foundation type that vary significantly in cross-section from these driven pile types. Transformed area and development length calculations are used to derive this modified method.
