Webinars
Olson Engineering has created a variety of webinar presentations that were originally hosted in a live format and are currently free to view. The webinar recordings are available in this section and cover a diverse range of NDE and geophysical topics as they relate to concrete & embankment dams, bridges, unknown foundations, tunnels, pipes & conduits, buildings & structures, seismic refraction, site classification, and soil compaction.
