The Beginnings of our Forensic Practice

RRJ HistoryIn January 1966, Charles Raths opened a one-man structural engineering firm called Chas. H. Raths & Associates.  Operating out of Chuck's house, this company was the seed that eventually produced the structural and architectural consulting firm known today as Raths, Raths & Johnson, Inc. (RRJ).  Chuck founded RRJ based on his experience as a designer, as a researcher with the Portland Cement Association, and as chief engineer for a large precast concrete producer.  

His goal was to put into practice a philosophy based upon quality engineering with particular focus on adhering to engineering fundamentals, attention to detail, and client service. RRJ HistoryThis ideal proved to be successful earning RRJ a reputation for its expertise as a problem solver and positioning the firm as one of the early forensic engineering practices in the country. 

In the early years, RRJ provided structural engineering design services to the precast/prestressed concrete manufacturers, architects, developers and contractors.  By the late seventies, the practice shifted to forensic work with Chuck Guedelhoefer, S.E., F.ASCE joining the firm to support the growth in forsenic investigation, specialized testing, and repair design services.

Now its third generation of leadership, under Kurt Hoigard, P.E., SECB, F.ASTM and Kenneth Lies, AIA,  the firm has continued to building an outstanding reputation by applying Mr. Raths original principles to projects and by its dedicated staff's continual contributions to thought leadership for the profession.
