Design and Manufacturing of Precast Segments

This course is designed to educate the industry, especially the design and engineering community, about the technical details and current product advancements/trends with the design and manufacture of precast concrete tunnel segments.  This course will help to show that all of the componentry and designs involved in segment production must work together as a single system and not independent parts.

This course is designed for engineers and designers who wish to learn about precast segment design.  This course is geared toward anyone who is interested in learning more about precast segments in general, from design, construction, and installation. It is helpful if registrants have a basic knowledge of precast segments.

Risk Management for Practitioners

The goal of this course is to improve the practice of risk management and by this improvement, to improve the outcomes for underground projects. This course will review the basic principles of risk management then move swiftly beyond these basics to inform participants about the application of these techniques to example project scenarios.

What can the participants expect from this one-day course?

  • An understanding of the basics and principles of risk management
  • Clear and applicable techniques for practical application of these risk management techniques in projects
  • An opportunity to work out a solution to a self-provided task/challenge on the spot
  • Complete course documentation electronically (on a SME stick) upon check-in
  • Exemplary solutions for practical exercises upon check-out
