Construction and Behavior of Drilled Shafts

COURSE NO: G01-002
Construction and Behavior of Drilled Shafts
Course Highlights

This online engineering PDH course presents an overview of general practices used for the construction of drilled shafts. It discusses influence of construction method and concrete quality on the development of side and base resistance. It describes load transfer characteristics of drilled shafts.


The use of drilled shafts has increased considerably in the last two decades due to their ability to carry large loads economically.  Rapid developments in drilling equipment and machinery have made it possible to construct very deep, large diameter shafts in almost all subsurface condition, including caving soils below groundwater level, rock, karstic foundations, and off-shore construction.


This 1 PDH online course is applicable to civil, structural, and geotechnical engineers as well as design and construction personnel working on construction projects that involve drilled shaft design and construction.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Understanding various types of drilled shafts and drilling equipment used in their construction
  • Identifying and developing knowledge in factors influencing the behavior of drilled shafts
  • Outlining influence of soil type, construction technique, and concrete quality on the ultimate performance of drilled shafts
  • Knowing possible issues resulting in softening of soil around drilled shafts constructed in clay soils, which ultimately result in lowering of side shear capacity
  • Distinguishing between load transfer mechanisms during loading along the side of a drilled shaft and at the bottom of a shaft in relation with increased loading and the amount of movement a shaft experiences
