Projects

Since INTERRA first opened its doors as Great Lakes Soil & Environmental Consultants, Inc. in 1996, we have been delivering project success non-stop. The depth and breadth of our project experience is second-to-none and our commitment to understanding and then achieving our clients’ specific project needs is what drives us forward.

In each of our core areas of expertise, engineering, inspection, and materials testing, we have completed a significant number of diverse projects and have accumulated an equally large number of success stories. Although our success stories are varied, most have a common element that describes how we overcame demanding project obstacles, met aggressive deadlines, or developed and executed creative solutions to complex problems that save time and money.

We invite you to review more of our work to see what we can do for you.
