When the quality of work and the speed to project completion are equally critical to a project’s overall success; commercial retail clients, industrial clients, auto dealerships — to name a few — rely on INTERRA for their engineering, inspection, and testing needs.  For these clients, INTERRA routinely provides its expertise in a wide variety of ways; including geotechnical studies with practical, cost efficient recommendations that allow projects to move forward and soil remediation projects that minimize disruptions to project schedule and budgets.

Because INTERRA has worked for so many commercial clients, we fully understand that speed is of the essence for commercial development projects.  Our client-driven personnel, internal systems, and reporting mechanisms are all structured to do just that…to move your project forward as quickly as practically possible in coordination with all of the project’s other consultants, contractors, and vendors.

A listing of some of our commercial development projects can be viewed below.
