Item 2 ?Review of Previous Minutes
The following inter-related TC32 activities
were discussed:
- guidelines ?Develop a general framework for geotechnical risk assessment
and management, several pages long, but expandable into sections on
specific applications.?It will be
aimed not at risk specialists, but at those who may be involved in such
work without adequate training.? TC32 Core Member Bill Roberds <broberds@golder.com>, who is
involved in a similar effort with ASCE GeoInstitute’s Risk Assessment and
Management Committee, is leading this effort.?Interested parties were supposed to
submit their ideas and existing guidelines (document, or ref and way to
acquire) to him by 31/12/02; TC32 member Ed Calle <
e.o.f.calle@geodelft.nl>
sent the link to the 'Probabilistic Model Code' of the Joint Committee
on Structural Safety (JCSS) <
www.jcss.ethz.ch>
(click button: JCSS Publications and then
The JCSS Probabilistic Model Code), although Section
3.7: Soil
Properties (part of part 3 of the PMC) had not yet been added
to the public domain, so he sent
it separately. Bill
has developed a draft annotated outline, but it will not be ready for
review by TC32 until fall of 2003. He will first circulate for comment
among TC32 Core Members and then, after TC32 Core Member approval, to a
wider audience. As pieces are
approved by TC32, they will be posted on the TC32 web site.
- glossary ?Develop a general glossary of terms for risk assessment and
management, covering about 50 ?100 items, consistent with other
glossaries and supportive of the above guidelines.?TC Member Lars Olsson <lars.olsson@geostatistik.se>
is leading this effort.?Interested
parties were supposed to submit their inputs to him by 31/12/02.?TC32 Core Member Ken
Ho sent a draft IUGS glossary to Lars for consideration.?Doug VanDine (vandine@highspeedplus.com)
is working on a glossary of risk terminology for geo-scientists in Canada; he is very much interested
in cooperating with TC32 (Lars Olsson) on this subject and Lars will
contact him. Robin Fell of JCT1 is finalizing a
short glossary (about twenty items) for the Canadian Landslide Conference
in Spring 2005, i.e., the IUGS glossary which was begun in 1997, and it
was suggested that this glossary be used by TC32 (rather than developing a
new one) although it may need to be expanded ?TC32 needs to comment on or
endorse this glossary ASAP.?The UN organization ISDR in Geneva is also working on a related
glossary, which Lars will coordinate with. Lars
has compiled a preliminary glossary comprised of 160 items, with
references and competing definitions, but it does not yet have examples ? he requests people to send him examples and references.?The glossary will not be ready for
review by TC32 until fall of 2003 ?Lars will first circulate for comment
among TC32 Core Members and then, after TC32 Core Member approval, to a
wider audience.?Once approved by
TC32, the glossary will be posted on the TC32 web site.
- bibliography ?Develop a bibliography for risk assessment and management,
in support of the guidelines and glossary.? To facilitate its use, it would be desirable that this bibliography
be categorized in terms of type (e.g., web page, non-peer-reviewed paper,
report, peer-reviewed paper, symposium, text book, etc.), and topic (e.g.,
see case studies below).?TC32 Core
Member Ken Ho <cge_lid@ced.gov.hk>
is leading this effort, coordinating with ASCE GeoInstitute’s Risk
Assessment and Management Committee (chaired by G.Fenton) who are also
developing such a bibliography ?indeed, the course notes presented on
TC32’s web page has an extensive bibliography, although it would need to
be updated and categorized.? Interested parties were supposed to submit their ideas and
references to him by 31/12/02; however, no one
did, although Denys Breysse (who attended the TC32 meeting) will send Ken
a list of French references in the near future.?Ken developed a preliminary
bibliography, which was handed out at the TC32 meeting.?However, the consensus of those at the
TC32 meeting was that it needed categorization and evaluation to be
useful.?A tentative categorization
(e.g., keywords) and evaluation scheme / procedure, consistent with the
guidelines and glossary, will be developed by TC32 Core Member Bill
Roberds and circulated for comment by TC32 members this fall.?Once the categorization scheme /
procedure has been approved by TC32, it will be applied to the reference
list for review by TC32.?Once
approved by TC32, the initial bibliography will be posted on the TC32 web
site, where it would be periodically updated per the categorization scheme
/ procedure.
- case studies ?Assemble an extensive set of case studies that demonstrate
various approaches and the value or benefit of the results of risk
assessment, for various types of applications.?To facilitate their use, it would be desirable
that these case studies be categorized in terms of scope, approach and
application, consistent with the above guidelines.?A potential problem may be the
confidential nature of some projects, which would require specific
measures to allow publication.?It
will be the author’s responsibility to obtain client approval.?TC32 Core Member Ken Ho <cge_lid@ced.gov.hk> is leading
this effort, coordinating with ASCE GeoInstitute’s Risk Assessment and
Management Committee (chaired by G.Fenton) who are also developing a set
of case studies.?Interested parties
were supposed to submit their ideas to him by 31/12/02; however, no one did.? Ken developed an example case study, which was handed out at the
TC32 meeting (see attachment).?TC32
Core Member Bill Roberds also handed out some example case studies, which
are actually promotional materials but could be easily modified to be
suitable (see attachment).?The
consensus of those at the TC32 meeting was that Ken’s example needed more
information (including author / contact, categorization / keywords, and
discussion of value / benefit, which in turns needs definition of
criteria) and more detail (similar to the discussion of approach,
including graphics, in Bill’s examples), but each case study should be limited
to 3 pages.?The categorization /
keywords will be the same as being developed for the bibliography.?To ensure completeness and uniformity,
Bill will develop a WORD template for case studies that can be downloaded
off the web site and then submitted electronically when completed by the
author.?T.H.Wu will be asked to be
the “gate keeper?of case studies, checking them to ensure that they are
complete and appropriate (e.g., there are no commercial messages and that
author certifies that client approval has been obtained) before posting
them on the web site.?Even so, the
web site will need a disclaimer (especially with respect to client
approval being the author’s responsibility, ala ASCE).?The template will be developed by TC32
Core Member Bill Roberds for review by TC32 this fall.?Once approved by TC32, the
categorization scheme and template will be posted on the TC32 web site.
- course notes ?Assemble a set of course notes, perhaps expanding on the
guidelines and other materials, to facilitate undergraduate and graduate
education in this area.?First,
conduct a survey of universities world wide to determine what courses are
offered and their content.?TC32
Member Mark Jaksa <mark.jaksa@adelaide.edu.au>
will lead this effort, but has not yet started.?Note:? Notes from a short course presented by G.Fenton et al at GeoLogan
in 1997 and at Madison Wisconsin in 1998 are the most current version, and
are available on the TC32 web site.
- prediction symposium ?Organize or sponsor a symposium in which various experts,
using the same information base provided by the organizers, would present
their risk assessment for a particular real-life project so that methods
could be compared.?However,
validation (in the form of comparing predictions to actual outcomes) may
not be possible.?Although Hong Kong was considering
organizing such a prediction symposium as part of its landslide conference
in Dec 2003, a more likely venue would be the conference on Landslides to
be held in Canada in Spring of 2005.?TC32
Core Member Ken Ho <cge_lid@ced.gov.hk>,
who is on the steering committee for the Canadian conference, will lead
this effort.?Interested parties
should submit their ideas to him by 31/12/03,
after which he will develop a proposal to organize or sponsor such a
prediction symposium for review by TC32.? If approved by TC32, the proposal will be implemented and posted on
the TC32 web site.
- website ?A website currently exists for TC32 <http://www.engmath.dal.ca/tc32/index.html>,
developed and maintained by TC32 Secretary G.Fenton <Gordon.Fenton@dal.ca>.?It is intended that this web site would
be the primary method for disseminating information re TC32, such as the
materials discussed above in addition to what is already contained there
(roster, news, meeting minutes, links, etc.).?If members would like their home page to
be linked to the TC32 website, send your URL to Gordon Fenton.?TC32 Secretary G.Fenton will continue to
lead this effort; however, see item 7.
As noted above, specific people and
milestones have been designated for each activity to ensure progress.?These activities need to be completed by the
end of TC32’s term, and reported at the ISSMGE conference in Osaka Japan in
Spring 2005.
Item 5 ?Future Activities
Item 5a ?Collaboration with JTC1
JTC1
(Joint International Committee on Landslides -?ISSMGE/IAEG/ISRM) led by Prof. Robin Fell is planning a Conference on
Landslide Risk Assessment in Canada in Spring 2005.?The steering committee for the conference
includes TC32 Core Member Ken Ho and TC32 Member Leonardo Cascini.?TC32 Core Member Bill Roberds volunteered to
help, if needed.?It was decided that
TC32 endorses this conference.?[Note:
This conference may conflict (in content) with the landslide conference in Rio the previous summer, as well as
(in dates) with the ISSMGE conference in Japan.]

which has been chaired by TC32 Secretary G.Fenton and will be chaired
starting this coming year by K.K.Phoon, who attended the TC32 meeting as
an observer; TC32 Core Member Bill Roberds and TC32 Members Wilson Tang,
Erik Vanmarcke, Bob Gilbert, Vaughan Griffiths, and T.H. Wu are also long
standing members of this committee.
- ASCE Pipeline Division’s Committee on Risk
Assessment, which has TC32 Core Member Bill Roberds as a member
- US Transportation Research Board’s Committee on Risk and
Reliability, which is chaired by TC32 Member Bob Gilbert
- Joint Committee JTC1 of ISSMGE ?IAEG ?ISRM on Landslides
(chaired by Prof. Robin Fell)
- International Committee on Large Dams (ICOLD)
- National Soil and Risk Working Committee is being formed in France (consisting of Denys Breysse ?Univ of Bordeaux, who attended
TC32 meeting as an observer, Theirry Verdel ?School of Mines,
and Jean-Louis Favre)
[Note:?After the meeting was adjourned, another collaborative organization was
identified.?The US National Academy of
Sciences is proposing a workshop on Probabilistic Risk Assessment.?TC32 Core Member Bill Roberds authored the
draft proposal with NAS member Tom Doe, suggesting close cooperation with TC32
and ASCE/GeoInstitute’s Committee on RAM.]
Item 6 ?Future Initiatives / Projects
It was felt that ongoing TC32 activities
(e.g., developing guidance, glossary / bibliography and case studies) were
significant and will entail as much effort as TC32 members will have available
- see Item 4 - Ongoing Committee Activities.?Hence, no other future initiatives / projects
were identified at this time.
Item 7 ?Web Page Development / Directions
As noted in Item 4 - Ongoing
Committee Activities, TC32 has a web page that is
currently maintained by Gordon Fenton on his computer.?He is willing to continue to maintain the web
page.?However, as the web page expands
to include the results of TC32 activities (e.g., guidance, glossary /
bibliography, and especially case studies), he may need assistance, for example
some small funds to pay a graduate student to maintain the site.?This was endorsed by the attending TC32
members, subject to available funds.
Item 8 ?Future Committee Meetings
The final meeting of TC32 will most likely
be in Osaka Japan in the spring of 2005 at the ISSMGE Conference (date to be decided
in August 2003).?Y.Honjo of TC23, who
attended TC32 meeting as an observer, has offered to jointly sponsor a
session.?TC32 could present the results
of committee activities, i.e., guidance, glossary / bibliography and case
studies.?This proposal will be discussed
with the TC32 Chairman and then with TC32 Core Members.
The location and date of the next meeting
of TC32 have not been established.?Considerations include: 1) the 2002 meeting was in Europe in the fall, the 2003
meeting was in USA in the summer, and the 2005 meeting will be in Japan in
the spring, so that the next meeting should be elsewhere and probably in spring
or summer 2004; and 2) it may be possible to do the meeting via videoconference.?One possibility would be at the International
Landslide Symposium in Rio de
Janeiro, Brazil in
June 28-July 2,
2004; two TC32 Core Members (Ken Ho and
Bill Roberds) will be offering a short course on risk assessment at this
venue.?TC32 Chairman F. Nadim will email
TC32 members and observers to let them know where and when the next meeting
will be.
Item 9 ?Other Business
There was no other business.
Closure
Meeting was adjourned at 9:30PM by TC32 Acting Chairman Gordon Fenton.
Signed by Bill Roberds, TC32 Core Member
and Acting Secretary (while G.Fenton was Acting Chairman).
