Greg Cummings: Engineering the Invisible—The Power of Commissioning

Most people have never heard of commissioning, but Greg Cummings and his company, UNVC, have built an empire around it. Commissioning is the process of making sure complex mechanical, electrical, and plumbing systems in large buildings actually work as intended—before they cause costly failures. From hospitals and universities to state prisons and massive commercial buildings, Greg’s team ensures everything runs efficiently, safely, and to code.

In this episode, Greg takes us through his unconventional path from aspiring lawyer to industry leader in commissioning. He explains why modern buildings are more complicated than ever, how tiny installation mistakes can cost millions, and why his job often involves fixing problems other contractors didn’t even know existed. We also discuss the future of the trades and why commissioning is a hidden gem for young professionals looking for a high-paying, in-demand career.

If you’ve ever wondered how massive buildings function behind the scenes—or how an entire industry exists to keep them running—this episode is for you!
