About

Isomer Project Group is a Greenville-based engineering firm serving clients both here in the Upstate and across the country. Locally, we provide civil and site design—site layout, grading, drainage, stormwater management, utility coordination, and permitting support—helping developers, owners, and builders turn raw land and early concepts into buildable, code-compliant plans. Both here and nationally, our team designs first-of-a-kind industrial process facilities, guiding pioneering technologies from concept through construction in fields like clean energy, advanced manufacturing, and sustainable fuels. Whether we're laying out a local site or engineering a facility that's never been built before, our clients get the same thing: technical rigor, straight answers, and a team that stays hands-on from first sketch to finished project. We're proud to bring that big-project discipline home to the community we're part of.
