GRC Engineering, Inc. is a structural engineering firm located in Oak Forest, Illinois. We have been in business since 1987 and are licensed in 45 States plus D.C. Our engineers have experience in fabrication, construction, we understand field issues, and can work with contractors and owners to find the best solution for both design and construction. Our project scopes range from sizing a single piece of steel to complete building design. We work with new designs as well as remodels, structural upgrades, and changes of use. We also perform structural observations and critical inspections. Our projects have included design with steel, concrete, masonry, wood, and aluminum. Our broad geographical base gives us extensive knowledge of a variety of building codes and we are dedicated to upholding the codes in the entire design to ensure the minimum required standards of safety are met and to help the permitting process run smoothly.
