Purpose and Background
These presentations were recorded at the 2021 GI Web Conference.
Understanding deep foundation behavior in intermediate geomaterials (IGMs) is essential for accurate design and construction. This presentation explores classification methods for IGMs, distinguishing them from soil and hard rock based on strength, Rock Quality Designation (RQD), and Standard Penetration Test (SPT) N-values. Key topics include static analysis methods, Wave Equation Analysis of Piles (WEAP) for construction control, and Load and Resistance Factor Design (LRFD) resistance factor calibration.
The presentation reviews empirical equations derived from extensive load test data for shaft resistance and end bearing in various rock types. Case studies illustrate the impact of IGMs on driven pile performance and highlight best practices for improving predictive accuracy. This session provides valuable insights for geotechnical engineers, foundation designers, and construction professionals working with deep foundations in complex subsurface conditions.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Define intermediate geomaterials (IGMs) and differentiate them from soil and hard rock based on strength, Rock Quality Designation (RQD), and Standard Penetration Test (SPT) N-values.
- Explain the application of static analysis methods, Wave Equation Analysis of Piles (WEAP), and Load and Resistance Factor Design (LRFD) resistance factor calibration for deep foundations in IGMs.
- Identify key parameters affecting shaft resistance and end bearing in IGMs and analyze empirical equations derived from load test data.
- Describe best practices for improving predictive accuracy in driven pile performance and list classification methods for IGMs used in deep foundation design.
Assessment of Learning Outcomes
Students' achievement of the learning outcomes will be assessed via a short post-test assessment (true-false, multiple choice, and/or fill in the blank questions).

How to Earn your CEUs/PDHs
This course is worth 0.2 CEUs /2 PDHs. To receive your certificate of completion, you will need to complete a short post-test and receive a passing score of 70% or higher within 30 days of the course.
How do I convert CEUs to PDHs?
1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
