Randy Hart, AIAPrincipalI joined OAC in 1982 and shortly thereafter became a principal. I am a licensed architect and have over 30 years of experience working on all types of buildings. Over the past 25 years I have watched OAC change from a company that worked mainly in the public sector to a company with a nice balance in the public and private sectors.
While working here I have changed my focus from designing buildings to investigating failing buildings. Forensic architecture and engineering is a very interesting field and provides insight to how buildings are actually constructed and why they fail. Using the knowledge we have gathered from taking hundreds of buildings apart we have developed a specialized area of expertise allowing us to assist and guide building owners, architects, and contractors in the effort to construct buildings correctly. >> View Resume |
