Exploring Subsurface Investigations, SPT, and CPT (Webinar)

In Exploring Subsurface Investigations, SPT, and CPT, you'll learn ...

• How to plan and execute effective field investigations
• How to choose appropriate exploration methods
• How to apply in-situ testing to extract meaningful geotechnical data

Overview

---

Subsurface exploration and in-situ testing are the cornerstones of reliable geotechnical design and construction. This comprehensive course merges two essential topics—subsurface investigation methods and in-situ testing using the Standard Penetration Test (SPT) and Cone Penetration Test (CPT)—to provide participants with a well-rounded understanding of site characterization. Engineers will learn how to plan and execute effective field investigations, choose appropriate exploration methods, and apply in-situ testing to extract meaningful geotechnical data.

Topics include planning fieldwork, selecting exploration tools for both small- and large-scale projects, and understanding the differences between sampling techniques. The course also walks through common drilling methods such as auger and rotary wash, as well as guidelines for minimum investigation standards. In the second half, participants will learn the application of SPT and CPT, including corrections to raw SPT-N values, soil behavior type classification from CPT data, and the use of test results in profiling subsurface conditions.

Ideal for civil engineers, geotechnical professionals, architects, and construction managers, this course delivers technical depth with real-world relevance. Whether refreshing foundational knowledge or learning new techniques, participants will gain valuable insights.
