Dr. Brierley has more than 38 years of experience with both the technical and non-technical aspects of underground engineering and construction management. From the technical perspective, Dr. Brierley began his career with the Bachelor of Science degree in Engineering from Tufts University in 1968 and the Masters and Doctorate degrees from the University of Illinois in 1970 and 1975, respectively.

Since his early project management work, Dr. Brierley has worked on literally hundreds of projects involving all types of underground design and construction, including soil and rock engineering, building foundations, braced excavations, ground improvements and slope stability.

During the construction of the Dupont Circle Subway Station in Washington, D.C., Dr. Brierley managed the instrumentation program, developing the foundation for his doctoral dissertation in the structural performance of large, shallow underground openings in rock. Since that time he has worked on more than 200 major soil and rock tunneling projects involving design, construction management and consultation for owners, contractors, engineers, public agencies and attorneys.

In addition to his considerable technical abilities, Dr. Brierley is expert in all aspects of office management, project management and business development.
