Welcome to the Rapid Excavation and Tunneling Conference, sponsored by the Society for Mining, Metallurgy & Exploration.

RETC is the only conference with a dedicated focus on the developments, technology, trends, and innovations that directly affect the tunneling and underground construction industry. Featuring a wide variety of technical sessions and speakers combined with our expansive exhibit hall, RETC will be a professional event you will truly enjoy and remember.

The Rapid Excavation and Tunneling Conference (RETC) is sponsored by the Society for Mining, Metallurgy & Exploration (SME). Held every two years, RETC is the renowned international forum for the exchange and dissemination of developments and advances in underground construction. The RETC advances the engineering and scientific knowledge of rapid underground excavation and tunneling through interdisciplinary meetings, publications, technical-educational exhibitions and encouragement of research. It also provides innovative solutions to the unique engineering challenges associated with the tunneling industry.

The committee will consider all abstracts covering any/all aspects of the tunneling/underground construction industry including, but not limited to, the following topics:

  • Contract Practices – Making a successful Project
  • Design – Pushing the Industry Envelope
  • Successful Alternative Contract Delivery
  • Overcoming Difficult Ground
