Purpose and Background

Borehole and sample logging forms the basis for all geotechnical evaluation and design. Sample classifications and descriptions are based on standardized procedures that produce uniformity and consistency in identification of materials necessary for proper design and avoiding misinterpretation. Unique geologic and geomorphologic conditions can be missed in the normal standardized approach without proper awareness and assessment of all of the factors revealed during investigation. Unified classification of collected samples alone is not sufficient on its own to define conditions and can lead to unanticipated construction difficulties and claims. This course will outline some of the shortcomings of the standardized approach and present approaches to observation and recording conditions to reflect additional factors relevant to design and construction.

Primary Discussion Topics

• Basics of drilling and sampling
• Laboratory classification of samples
• Field classification of samples
• Limitations of sampling methods
• Geologic and Geomorphologic factors relevant to engineering design and construction
• Drilling conditions to note
• Sample versus strata descriptions
• Groundwater observations and measurements
• Using the comments/remarks field on logs

Learning Outcomes

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

• Explain the basics of drilling and soil sampling
• Explain classification basics
• Explain and apply the knowledge the limitations of common drilling and sampling methods
• Apply knowledge of geologic and geomorphologic factors and relevance to properties of soils
• Apply stratum description concept relative to sample classification
• Explain what to watch for in the field to produce more effective field logging

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).

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]
