will also contact member societies to access new potential
(young) participants within the field.
Generate a list of major publications on frost geotechnics.
Objective 2: Guidelines and technical recommendations
Collection of available standards: European standardization
work has started under CEN-TC227/WG4, Task Group 5,
Frost susceptibility. Seppo Saarelainen participates in this
work. The TC will collect information from recent work in
USA (ASTM has a committee on Frozen soil and Rock),
Canada, Russia, China and Japan.
Overview of standards, codes and guidelines will be
established during the period.
Evaluation of similarities and differences will be carried out
during the period.
Based on the previous items 1-3, guidelines and
recommenddations for practice will be discussed.
Objective 3: Assist with technical programs of international
and regional conferences organized by ISSMGE
The TC will contribute to this objective. At present time,
timetable is not available.
Objective 4: Interact with industry and overlapping
organizations
Cooperate with International Permafrost Associations Work
Group for Permafrost Engineering. Several of the TCs
members are also member of this group. Re-establish
cooperation with organizations working on artificial ground
freezing.

TC302 - FORENSIC
FORENSIC GEOTECHNICAL ENGINEERING
Chair: V.S. Rao
TERMS OF REFERENCE
Introduction:
Forensic Geotechnical Engineering (FGE) deals with
investingating failures attributed to geotechnical origin, not
only from technical, but also from legal and contractual
viewpoint. Cases of remediated installations where the analysis
and evaluation of adopted remedial measures may be subjected
to legal scrutiny with regard to their effectiveness and
economy, as also Geotechnical based distress in structures due
to natural hazards including seismic damages fall under this
purview. The commonly adopted standard procedures of
testing, analysis, design, and construction may not be adequate
for forensic analysis. The test parameters and design
assumptions must simulate the actual conditions encountered at
site. The Forensic Geotechnical Engineer (FGEr), who is
different from the expert witness, should be able to justify the
selection of these parameters and test procedures in a court of
law. Hence, he has to be totally familiar with the investigative
protocol and the jurisprudence system of the country.
Objective:
To prepare a guidance manual for forensic analysis of
geotechnical failures.
Scope:
The guidelines will be prepared under nine chapters as follows:
1) Collection of data,
2) Characterization of distress,
3) Diagnostic tests,
4) Back analysis,
5) Instrumentation and monitoring,
6) Development of failure hypothesis,
7) Reliability checks,
8) Legal Process and Jurisprudence, and
9) Case histories
Contents of chapters:
Ch. 1: Collection of data: This chapter will be mainly based on
desk study. A field reconnaissance survey of the project
will also have to be done to support the data. The
history of the project from the concept stage to the
execution stage will have to be studied. Interviews with
designers, representatives of the execution agencies,
etc, will have to be done. Meteorological data including
the seismic activity - if any- will also have to be
collected. In short all the data required for the final
analysis will have to be collected in this stage. (Provide
a check list?)
Ch. 2: Characterization of Distress : This chapter has to
include three aspects, viz: classification, geometry of
failure surface and progression of failure. Under
classification, the severity of the distress, as well as
whether it is a bearing failure or a deformation failure,
etc., will have to be assessed from the observation only.
The geometry of failure surface preferably in 3D format
will have to be developed. The progression of the
failure as observed in the site will also have to be
recorded. The records maintained by field engineers
