About the DFI Tunneling & Underground Committee

The purpose of this committee is to identify and facilitate the advancement of new methods and technologies for design, construction, inspection, maintenance and operation of tunnels and underground systems. The committee will foster technology transfer among the owners, stakeholders, designers, contractors, and material suppliers involved in the use and construction of tunnels and underground structures. Collaboration will also be fostered with the academic community, equipment suppliers, and major tunnel contractors and owners to address research needs and knowledge gaps. It will also promote the education and training of students at the graduate and undergraduate levels, fostering and developing emerging industry leaders in this field of practice. Examples of technical focus areas for the committee include: conventional and mechanized excavation methods, design practices for tunnel liners, the use of new materials in construction, waterproofing and water control systems, contracting methods, and the allocation of risk and construction practices.


Contact Co-Chairs Dave Klug or Jim Morrison for more information or to join the committee.
