INSTRUCTOR: 
Garland Likins, P.E., M.ASCE

Course Length: 90 minutes

Purpose and Background

Ensuring the integrity of deep foundations is critical to structural safety and performance. This presentation explores various non-destructive testing methods used to assess the geotechnical and structural capacity of drilled shafts, auger cast piles, and driven piles.

Key topics include high-strain and low-strain integrity testing, cross-hole sonic logging, and thermal integrity profiling. Real-world case studies illustrate common foundation defects, their impact on serviceability, and effective remediation strategies. Attendees will gain insights into best practices for preventing foundation failures and improving quality control during construction. This session provides essential knowledge for engineers, geotechnical specialists, and construction professionals seeking to reduce risk and enhance foundation reliability.

Learning Outcomes

Upon completion of this course, you will be able to:

• Explain the importance of deep foundation integrity testing and its role in preventing structural failures.
• Identify common foundation defects detected through non-destructive testing methods such as cross-hole sonic logging and thermal integrity profiling.
• Describe the principles and applications of high-strain and low-strain integrity testing for different foundation types.
• Analyze test results to assess structural adequacy and recommend appropriate remediation or quality control measures.

Webinar Benefits

• Understand the principles underlying various integrity assessment options
• Learn the foundation preparation requirements for the testing
• Understand interpretation of the basic measurements obtained
• Find out about advanced analysis methods

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

Who Should Attend?

Civil engineers seeking to understand various options available to assess the quality of foundations either recently installed or existing structures will benefit from this webinar. This webinar is intended for both private and public sector engineers who design or specify deep foundations.

Webinar Outline

• Discuss the need for testing
• Review testing by available pile accessibility
• Discuss High Strain Integrity Testing (for driven piles)
• Present Low Strain Integrity Testing (Pulse Echo, Shape estimation)
• Review Crosshole Sonic Logging and Single Hole Sonic logging
• Discuss Thermal Integrity Profiling
• Present Pile Installation Testing for augercast piles
• Discuss Parallel Seismic and Parallel Inductive testing

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
