Join Us for the Next Dowding Lecture in Los Angeles!
We’re thrilled to share that the next installment of the acclaimed Dowding Lecture is just around the corner—this time, coming to Los Angeles on July 7th, 2026!
Dr. Dowding is once again set to deliver a practical and thought-provoking lecture focused on:
- Vibration fundamentals
- Structural response
- Monitoring strategies for construction sites
- Real-world applications and case studies
Our previous attendees, Herb Singleton, Cross-Spectrum Acoustics Inc., and Rayan Shamas, GZA GeoEnvironmental summed it up perfectly:
After having referenced Dr. Dowding’s “Construction Vibrations” text for over twenty years, it was a pleasure to hear directly from the man himself. The research, evidence and conclusions presented at the talk were extremely useful and will help tremendously in monitoring and assessing vibration from construction projects.
– Herb Singleton, President & Founder of Cross-Spectrum Acoustics Inc.
Having been in the instrumentation business for the majority of my career, I was drawn to the history behind the developmentof today’s most widely used criteria for vibration monitoring. Though rich in substance and content, I felt the lecture sparked an even further curiosity about Dr. Dowding’s globally sourced case studies. I would definitely recommend this lecture.
– Rayan Shamas, Senior Project Manager at GZA GeoEnvironmental
