Training/Experience: CTA’s HPS has had significant experience in the areas of materials and systems; building behavior and pathologies; historic materials and their degradation; and how weather and other outside sources impact character-defining features. Our healthy working relationships with the National Park Service and State Historic Preservation Officers has strengthened our knowledge base, our ability to receive project approval by the reviewing authorities, and the success of our preservation solutions. Our staff regularly participates in and leads historic preservation workshops.
