Historic Preservation

We love history.

We specialize in structural design and analysis of historical preservation projects. We have been recognized for excellence in restoration and rehabilitation by the Georgia Trust for Historic Preservation. Our services are sought-after because our approach ensures that structures remain safe while preserving the original construction and architectural design that make these sites unique. We have a strong system of quality control, ensuring preservation code compliance.
