Greetings!
Acentech remains committed to participating in various environmental and transportation conferences. Jeff Zapfe and I hosted the panel discussion Groundborne Vibration - Methodologies, Mitigation & Monitoring at the California Association of Environmental Professionals Conference held May 6-9 in Sacramento, CA. Next, we're looking forward to the National Association of Environmental Professionals Annual Conference held May 21-24 in Portland, OR. Jeff Zapfe will also present Predicting the Effects of LRT Construction Vibration on University Research Equipment at the APTA Rail Conference, June 3-6 in Dallas, TX. We hope to see you at one of the upcoming conferences.
Sincerely,
Ray Nugent
Director, West Coast Office

Project Spotlight: North Carolina Research Campus
 Acentech worked with Narmour Wright Associates on the design of a new research building at the North Carolina Research Campus. Because the site is located only 350 feet from an active freight and passenger rail line, the owner had concerns about rail vibrations impacting several vibration-sensitive spaces, particularly a basement lab that would house a nuclear magnetic resonance (NMR) imaging facility.

Learn More: Monitoring Construction Vibrations at Sensitive Facilities
Construction-related vibrations, while temporary, have the potential to disrupt vibration- or noise-sensitive operations in adjacent hospitals, laboratories, and high-technology fabrication facilities. Disruptions can be minimized by planning, monitoring vibration in sensitive areas in relation to relevant criteria, and adjusting of construction activities on the basis of alarms.

Meet Our Team: Eric Ungar, Eng. Sc.D., P. E., Chief Engineering Scientist
Dr. Eric Ungar has won international recognition for his six decades of contributions in the areas of vibration and structure-borne sound. He recently was awarded the Gold Medal of the Acoustical Society of America, that institution's highest honor.
Eric has participated in numerous projects that involved noise and vibration concerns related to transportation, structural, and environmental noise. He has focused in the past few years on facilities that accommodate extremely vibration-sensitive equipment and on structures that need to withstand intense noise and vibration. He is well known for his work on structurally transmitted noise and high-frequency vibrations and for having developed widely used means for predicting footfall-induced vibrations in buildings. Eric's recent work has dealt with means for permitting construction near sensitive facilities to proceed without adverse effects on activities and instrumentation that are susceptible to vibration-related interference or damage and has been instrumental in the application of these means in projects for several major hospitals and research facilities.
We invite you to contact Eric to learn more about noise and vibration solutions.
