We’re well-versed in the delicate balance between making sure an older building is safe while maintaining its historic fabric. We have a long history of creating retrofit designs that use the most efficient, state-of-the art structural engineering techniques while leaving visitors scratching their heads when searching for any evidence of new construction. After implementing the first use of base-isolation in a historic structure and working to keep some of America’s most precious historic buildings safe, we take pride in our ability to integrate the new with the old in subtle but strong ways.
