COURSE DESCRIPTION:

This course is part of a series to develop a training and qualification/certification program for geotechnical inspectors and field personnel. The course follows FHWA guidelines and practices for subsurface investigations. Topics addressed in the course include exploration equipment and methods, safety, borehole sealing, drilling and sampling requirements and criteria, proper visual classification and description of soils and rocks, common drilling errors, and dealing with difficult subsurface site conditions. A 2-hour qualification exam is administered at the end of the course.

OUTCOMES:

Upon completion of the course, participants will be able to:

• Explain the investigation specialist's general role and duties, as well as the importance of coordination and communication with the field personnel and engineers
• Explain the purpose of geotechnical subsurface investigations and why adequate, consistent, and quality investigations are essential
• Identify the major components of the typical subsurface investigation plan
• Identify common drilling rigs, uses, and components
• Explain the importance of accurate borehole logging and documentation
• Describe the importance of accurate groundwater investigations
• Discuss safety issues involving operation of a drill rig

TARGET AUDIENCE:

The target audience for this course includes drillers, drilling inspectors, engineers, geologists, and technicians involved in field data collection and quality assurance of subsurface investigations.
