It will be extended to Spanish and Korean in the near future. Definitions and/or explanations of “TBM Glossary” in French and English have been completed and will be posted on the ITA website.

It is decided that since the standards and manuals are so much different by the countries, a reference book will be made to list up related references of the mechanised tunnelling from member nations rather than writing a new “ITA recommendation of mechanised tunnelling”. It is determined that WG-14's next tasks will be to establish the mission of WG-14 and to make a list of remarkable mechanised tunnelling projects with assessments added by WG-14. The information of challenging, successful, and troublesome projects will be gathered with a contact person's list including owners, contractors, consultants and machine manufacturers. The special team is formed to propose “the mission of WG-14” with WG members' approval. Also, three subgroups are formed and subgroup leaders are nominated to create a list of remarkable mechanised tunnelling projects. Completion of the list is expected by December 2005 with our members' unlimited efforts.
