The document on "Risk Management of Tunnelling Projects", approved in 2003 has been published, and the recommendation on "Settlements induced by Tunnelling" is complete and being submitted to the Executive Committee for review. A first draft report on "Site Investigations" has been prepared and reviewed. For the coming year, the Group will work on the completion of this report and initiate a new action on the "Monitoring and Control of Underground Works". The group has produced several documents over the past years, and more areas of investigation can be foreseen for the development of future works.

WG3: "Contractual Practices in Underground Construction"

New Animateur: A. Dix (Australia); New Vice Animateur: M. Smith (Switzerland); Tutor: Y. Erdem (Turkey)

The contractual practices group has commenced its revision and update of the ITA's general principles for underground construction contracts. Innovative financing options, project delivery and construction and maintenance techniques all requiring reconsideration of ITA's guiding principles and the formulation of new globally applicable themes for contracting. The reinsurers recent entrance into risk management was identified as a significant market development in need of urgent consideration within ITA's contractual practices framework.

WG5: "Health & Safety in Works"

Animateur: D. Lamont (United Kingdom); Vice Animateur: W. Chromy (Germany); Tutor: M. Belenkiy (Russia)

Nine member nations participated in the meeting. The "Safety in Tunnelling" CD-Rom project has been completed. The revision of the “Guidelines for good occupational health and safety practice in tunnelling” continued and it is hoped to have this document completed prior to the 2005 meeting. The Group agreed to commence work on a new project relating to guidance on fire safety for TBMs and other tunnel machinery. They hoped to collaborate with a number of organisations currently interested in the subject.

WG6: "Maintenance and Repair of Tunnels"

Animateur: H. Russell (USA); Vice Animateur: M. Muncke (Germany); Tutor: A. Haack (Germany)

The meeting group is attended by members from 14 nations. They were Belgium, Egypt, France, Germany, Italy, Japan, Korea, Netherlands, Republic of China, Romania, Singapore, Switzerland and United Kingdom, and the United States. The Working Group reviewed the final draft of Document Guidelines for Structural Resistance for Road Tunnels, a joint document with the International Road Federation. This document is to provide guidelines for better protection of road tunnels in the event of a severe fire. In addition to the review of the document Mr. Rene Van De Bosch of Netherlands provided a presentation on the Runhamer Fire Test which was performed in Norway this year. The Working Group elected to continue our work by forming two task forces one to develop a similar guideline for Fire resistance for Metro systems and the other to start to develop a Rehabilitation Manual for Tunnels.

WG11: "Immersed & Floating Tunnels"

Animateur: J. Saveur (Netherlands); New Vice Animateur: J. Baber (United Kingdom); Tutor: Y. Leblais (France)

Nine countries were represented at the meeting by a total of 14 participants of which Indonesia, Hungary and Singapore were represented for the first time. Chris Marshall has requested to step down as vice-animateur. The working group owes him a lot for his contributions.

The catalogue of immersed tunnels has been handed over to ITA's webmaster. The preparation of the report on settlements will go ahead as outlined in the meeting. The new activity will be to list the specific aspects of immersed tunnels to be included in the system of Instrumentation, Documentation and Verification, IDV for short, being a method to assure the viability of a facility from conceptual design throughout its operational life.

WG12: "Shotcrete Use"

Animateur: K.F. Garshol (USA); New Vice Animateur: A. Ishida (Japan); Tutor: E. Grov (Norway)

The meeting had 13 participants from 12 different countries. Task 1 (State of the Art Report) has received contributions from 21 countries and is now ready for publishing. Reports on fire protective sprayable mortars; certification systems for shotcrete operators; and structural fibres for shotcrete reinforcement, are all planned to be ready at the Istanbul meeting. Contact with WG19 will be established to check for possible common topics.

WG14: "Mechanization of Excavation"

New Animateur: K. Fukumoto (Japan); Vice Animateur: F. Amberg (Switzerland); Tutor: K. Ono (Japan)

“Classification and definition of TBMs with recommended keywords” has been completed with schematic drawings and will be on the ITA website soon. Also, as the “TBM Glossary” has been completed in English, French, German and Japanese, it will be on the ITA website. Besides, “TBM Glossary” will be extended to other languages, such as in Italian, in Spanish, in Korean and in Chinese, which will be good benefits to prospected authors of scientific papers of tunneling. The scope of work and schedule for “ITA Recommendation in Mechanized Tunneling”, which is the next theme for WG-14, was discussed. It is determined that it will be just focused on excavating machine and fundamental equipments for functioning, which indicates that some comments on segments and other relevant items would also be included. Since robotics was still far from the field practice, those would not be included. Since completion of “ITA Recommendation in Mechanized Tunneling” will be great benefits to member nations, it is expected to be completed in two years or so with our members' unlimited efforts. Three subgroups (EPB, Slurry, Hard rock TBM) were formed for this task.
