Course Outline

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 are being achieved with new hammers, dynamic quality control methods have been adopted, wave equation analysis is being widely used, and higher strength materials are becoming common.  Auger-cast piles are being used with increasing frequency, high capacity drilled shafts are being utilized more frequently and new design and specifications have been adopted in many codes and specifications.  This course presents modern design procedures for deep foundations and discusses latest developments. Practicing professionals

Objective • To provide the understanding of the fundamentals of the design process for deep foundations
• To provide adequate knowledge in the proper selection of a deep foundation system
• To present modern techniques for the design, installation, and verification of deep foundations.

Who Should Attend Consulting engineers, geo-technical engineers, civil and structural engineers, project managers and construction engineers, contractors, and any technical professional involved in the design, construction, inspection, testing and specification of deep foundations (driven piles, cast-in-place piles, or drilled shafts).

Concluding Remarks and Final Adjournment

There will be a one-hour lunch break each day in addition to a refreshment and networking break during each morning and afternoon session.

After participating in the seminar, you will be able to:

• apply the latest subsurface investigation methods learnt at the seminar to your deep foundation design projects
• use the knowledge of the new standards and procedures for the design and installation of deep foundations 
• determine capacity both by static and dynamic methods
• optimize the selection and design of deep foundations using the knowledge gained in the short period of three days
• add new tools to your repertoire for consulting engineering field related to deep foundations.
• Select suitable deep foundation systems and associated equipment for your projects
• design axial and lateral geotechnical capacity of driven piles and drilled shafts, both individually and as groups
• carry out the wave equation analysis for the design and installation of driven piles including driving problems
