​What are architect’s and engineer's responsibilities and how liable are they when something goes wrong? Each state has its own rules regarding the practice of architecture and engineering. By examining contract documents, communication between parties, and other data, a timeline can be established.  From there, responsibility and liability can be ascertained. Dr. Henry's PhD Dissertation not only discusses this topic, but he's also written a book on it, Return of the Master Builder, and been called to testify on E&O matters across the country.
