Buildings near rail lines are subjected to vibration that can be disruptive to occupants. As vibrations travel up through a building’s columns they decrease floor-by-floor as…
“Acentech is easily the best place I have ever worked. I have great clients and outstanding colleagues, and have had the chance to work in places spanning the gamut from concert halls to subway tunnels.”
As president of Acentech, Dr. Jeffrey Zapfe provides the corporate leadership that sustains the technical acumen, dynamic culture, and client-focused approach for which Acentech is known. Jeff joined Acentech in 1998 and led the firm’s Noise and Vibration group for many years before becoming president. His consulting expertise is in the areas of vibration, structural dynamics, vibration sensitive facilities and equipment, and vibration isolation. His work includes the analysis of structures at the design stage as well as the measurement, analysis and mitigation of vibration in completed buildings.
Jeff’s most recent work has included projects concerned with measurement and attenuation of building vibrations, construction vibration mitigation, prediction and control of footfall-induced vibrations of floors housing sensitive equipment, and evaluation and mitigation of ground-borne noise and vibration due to transportation systems. Of note, he was the principal investigator of a Transportation Research Board study to determine the relationship between railway-induced vibration and human annoyance.
I was born and raised in Canada but I have been in the US so long that I find myself thinking that those Canadians sure talk funny. To relax, I am an avid golfer (although lately my skill level often interferes with the relaxation part). To date, the highlight of my golf career is a 77 on the Old Course at St. Andrews (but that was a long time ago). The photo on the right shows me just after an unplanned visit to the Road Hole bunker. I also love to go to Italy. The first photo was taken in 2019 in Montefalco which is easily my favorite town in Italy – great food great wine, what more can you want. The second photo was taken in my back yard in 2020 during a COVID-inspired “fake trip to Italy.” My wife made the cappuccino, but I made the cornetti (they took all day, but they were good).
