Purpose and Background
The purpose of this course is to present modern techniques for the design, installation, QA/QC, and verification of deep foundations. Over the past twenty-five years major changes have occurred in the deep foundations industry. New improved methods have been developed for installing all types of deep foundations, increased loads are being used, and new quality control procedures have been developed. For driven piles, higher loads can be achieved with new hammers, dynamic quality control methods have been adopted and widely used, and higher strength materials are becoming common. Auger-cast piles are being used with increasing frequency and expanded applications. High-capacity drilled shafts are being utilized more frequently made possible by new construction techniques and testing methods. New design methods and standards have been adopted in many codes and specifications. This seminar will present modern design procedures for deep foundations including discussions on new developments.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Explain the minimum recommendations for site investigations, geotechnical laboratory and in-situ test methods and property selection guidance for deep foundations design and construction.
- Select the appropriate deep foundation systems and assess the appropriate foundation element installation equipment and construction procedure.
- Conduct design and analysis of single piles and pile groups subject to axial and lateral loads and moments.
- Apply the use of wave equation analysis for the design and installation of driven piles.
- Understand and specify the use of static and dynamic testing and monitoring methods for structural integrity and geotechnical load carrying capacity.
- Select the key project variables and requirements within construction specifications and plans for deep foundations.
- Communicate the advantages and disadvantages of various deep foundation types.
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).
Who Should Attend?
Geotechnical engineers, construction engineers, contractors, structural engineers, owners representatives, CEIs, or any professional involved in the design, construction, inspection, testing and specification of deep foundations (driven piles, cast-in-place piles, and drilled shafts).

How to Earn your CEUs/PDHs
This course is worth 1.4 CEUs/14 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]
