10.    Co-ordinating Committee on Symbols₁_Units and Definitions

During a meeting in Paris the Presidents of the 3 International Societies insisted for the setting up of a Co-ordinating Committee on Symbols, Units and Definitions. This proposal was agreed by the Committee of Secretaries General, which should put it before their respective Executive Committees. The ISRM has designated as members:

Prof. M. Langer (FRG)

Prof. H. Pincus (USA)

Mr. p. Dufaut (France)

The ISSMFE decided in Istanbul that Mr. Baguelin should be asked to appoint three members of the Subcommittee on Symbols, Units and Definitions of ISSMFE as members of the co-ordinating committee. Until yet this designation has not been madę. The IAEG also agreed to participate in a co-ordinating committee on symbols, units and definitions.

The members are:    Prof. Sirgirov (USSR)

a member to be designated by the French Society a member to be designated by the British Society Until yet the names of these two members have not been received. Unfortunately it takes a very long time to get the names of all the members, with the consequence that the co-ordinating committee cannot start to work.

11.    J£in t _ co^i 11 ee_ f or _ the_ exchange_ o f _Compu te r_ Próg rams_in_ Geomechanics

The Institute for Publicity and Exchange of Geomechanics Computer Programs, madę formal submission to ISRM and    IAEG, inviting affiliation with    the Institute. The    ISRM at

Denver madę a favourable decision. However all this    is linked with rather    intricate    but

fundamental problems of organization and interdependence, which was thoroughly discussed by the committee of Secretaries General. The decision was taken that both ISRM and IAEG should wait to take further steps, until the relationship of the Institute for Publicity and Exchange of Geomechanics Computer Programs and the ISSMFE should be clarified.

12.    Extension_of_the_Permanent_Co-ordinating_Secretariat_to_other_Societies

The committee of Secretaries General decided that for the moment the Permanent Co-ordinating Secretariat should not be extended to the International Association for Hydro-Geology, nor to other Societies, as    for instance the International Society of Tunneling.    However    there

should be no objection    that a Secretary General should    invite a Secretary General of

another International Society, to join him as an adviser and an observer for some special points on the Agenda.

13.    ęo-ordinating_Committee_on_Sitę_Inyestigation

The setting up of a co-ordinating committee on Site Investigation was agreed by the ISRM.

The member of ISRM is Professor Serafim (Portugal). This committee was also agreed by IAEG. However until yet the names of the delegates have not been officially notifidd to the Permanent Co-ordinating Secretariat. The name of Dr. Price (U.K.) has been advanced but has not confirmed until yet. The setting up of this committee is on the agenda of the Tokyo meeting of the Executive Committee of ISSMFE.

14 • ę2l2EŚi0^ing_ęommittee_on_SamEling

The setting up of the Co-ordinating Committee on Sampling has been agreed by the ISRM.

The delegate is Dr. Bieniawski, South Africa. The IAEG has no own committee. IAEG is of the opinion that sampling is a part of Site Investigation, and that there should be but one committee on Site Investigation and Sampling. If the two other International Societies should prefer to have two separate committees, IAEG should only delegate an observer to the Co-ordinating Committee on Sampling. The setting up of a Co-ordinating Committee on Sampling is on the agenda of the Tokyo meeting of the Executive Committee of ISSMFE. Also the delegates should be designated.

From the report can be deduced that the work of the Permanent Co-ordinating Secretariat is not easy, and that it takes months and years before the co-ordinating committees can start working. When the names of the delegates will be available, there still remains the problem of the travel costs, which can only be solved by the goodwill of the institutions, where the delegates are working.

The most effective contribution of the Permanent Co-ordinating Secretariat for the moment being, is the possibility given to the Secretaries General to meet yearly, and to have a large exchange of ideas and of their mutual problems.

Prof. Dr. ir E. De Beer

Secretary of the Permanent Co-ordinating Secretariat
