Historic Preservation


"In a sense, all of our work is preservation in that on every project, we endeavor to sustain existing buildings and structures—old or new—and enhance their continued serviceability."

— Deborah Slaton, Principal

Working within established preservation guidelines and standards, our architectural, structural, and conservation professionals balance the need to provide practical, long-term solutions with the ability to sensitively conserve a structure’s historic fabric. From planning and investigation through implementation, no firm is better qualified to respond to the technical and aesthetic needs of significant historic structures.

Historic buildings and structures are a tangible link to our past. From private owners to large institutions and government agencies, clients worldwide trust us to preserve their historic properties for generations to enjoy. Our preservation professionals have extensive expertise in the repair and conservation of a wide range of historic construction materials and building systems. Using sophisticated testing and materials analysis techniques, we apply the science of preservation to develop appropriate and innovative solutions to restore historically significant properties.
