The team at Cornerstone Commissioning is passionate about building performance. We provide an independent sanity-check to design teams and building owners, helping ensure that facilities function in “real life” the way they were designed to on paper. When you hire Cornerstone, you end up with a better building. With more than 1,300 projects in our portfolio, we know what it takes to deliver high-performance facilities. We’ve practically seen and done it all. Founded in 2001, we were one of the first specialized commissioning firms in the industry. Back then, we were focused on vivarium and biocontainment spaces. Today, we perform commissioning for a variety of buildings and clients throughout the US. Cornerstone Commissioning, LLC. is a member of the Building Commissioning Association.
