The Drilled Shaft Foundation Inspector Certification Course is designed for those individuals responsible for inspecting the installation of drilled shaft foundations. Suggested participants would include contractor and agency personnel who have responsibility for the installation and inspection of drilled shaft foundations.
The Drilled Shaft Inspection Qualification Class provides a basis for state qualification of personnel as Inspectors of Drilled Shaft construction on FDOT projects. The goal of this course is to provide Inspectors with the practical knowledge, accepted standard Industry practices and specifications for fulfilling the role of a Drilled Shaft Inspector. This course is designed to be of most benefit to personnel involved in performing inspection of drilled shaft construction operations.
Drilled Shaft Foundation Inspection is a stand-alone course developed to provide a basis for local, regional, or national qualification of drilled shaft foundation inspectors. The goal of this course is to provide inspectors with practical knowledge and standard industry practices for the inspection of drilled shaft foundation construction. A 2-hour qualification exam is administered on the third day of the course.
The course follows recommended specifications and practices for drilled shaft construction but may be modified to follow local agency specifications and practices.
Upon completion of the course, participants will be able to:
