Purpose and Background

This webinar discusses principles of construction vibrations. It describes the main mechanisms of wave generation during construction projects and the physics of wave propagation and energy dissipation. It illustrates the scatter in commonly used attenuation equations. It discusses various thresholds for human perception as well as possible direct and indirect potentially damaging effects to various types of structures. It presents special effects such as resonance and effects of dipping rock ledges. The webinar summarizes various ways to monitor and analyze construction vibrations, with an emphasis on the newest technologies. Finally, the webinar closes with some mitigation techniques that can be employed to minimize the risks and potential claims associated with construction vibrations.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
