Executive Vice President - Continental Construction Co., Inc.

"Eakas Corporation is delighted to endorse Chad Stewart and Associates. CSA was the structural engineering firm responsible and instrumental in the construction of a 275,000 square foot facility in Peru, Illinois for us. We experienced a weather related catastrophic incident during construction. CSA was on-site in hours evaluating the structure and foundations. They worked closely with the General Contractor, PEMB supplier and engineers to keep the project on time. CSA went above and beyond to ensure our manufacturing facility was of the highest quality for the investment. We appreciate their diligence and detail to our project.”
