With more than 44 years of experience in the heavy and tunnel/underground construction industry, Ray Henn offers contractors, engineers, owners, attorneys and insurers assistance with their projects.  Ray's 25 years of field experience, working for both contractors and construction managers, combined with his return to school to earn a PhD in Mining and Earth Systems Engineering from the Colorado School of Mines gives him an understanding of the practical as well as the technical and engineering requirements of heavy and underground construction projects being constructed in today's evermore challenging geologic, groundwater, environmental, and sometimes politically sensitive conditions.
