Gary Brierley - Doctor Mole


DuPont Circle Subway Tunnel Project
About Doctor Mole . . .
Dr. Brierley began his career in 1968 with the Bachelor’s Degree in Civil Engineering from Tufts University and the Masters and Doctoral Degrees from the University of Illinois in 1970 and 1975, respectively.  During that time Dr. Brierley was fortunate to work on the instrumentation program for DuPont Circle Subway Station in Washington, D.C.; a project that formed the basis for his doctoral dissertation. Since that time, Dr. Brierley has devoted his entire professional career to the design and construction management of underground openings.  

Dr. Brierley has been involved with two successful start-up design practices; Brierley and Lyman and Brierley Associates.  He has served as President of the American Underground Construction Association, Chairman of the Underground Technology Research Council, and as a member of the U.S. National Committee on Tunneling Technology.  He is a member of several professional societies and has authored more than 200 technical papers and articles for tunneling publications including the “Ask Dr. Mole” column for TBM magazine.
