INTRODUCTION

Recently, TC32 has been renamed TC304. Prof. KK Phoon

chairs TC304 for the period 2009–2013 and proposed four

tentative task forces for TC304. One of these Task Forces, TF3,

aims to focus on coordination of geotechnical risk management

with the broader international risk community. This proposal is

a first outline about the possible main objective, activities,

deliverables and participants of TF3

Objective:

Over the last years, geotechnical risk management, as well as

project risk management, developed quite rapidly. However,

both complementary types of risk management are often still

separated in the day-to-day practice of construction projects.

This situation avoids catching all potential risk management

benefits, in terms of improved safety and quality, cost and time

savings, as well as improved reputations of large and smaller

construction projects.

The main objective of TF3 is contributing to the combination

and integration of discipline-based geotechnical risk

management with broader and more generic project risk

management, in theory and in practice. This should contribute

to more safety and quality, lower costs and faster completion of

all sorts of construction projects, worldwide.

Activities:

The main TF3 activities in order to contribute to the fore-

mentioned objective are:



Establishing an international Task Force, TF3 (to be

completed by the end of September 2010);



Drawing a TF3 Activities Plan by the TF3 members (to be

completed by the end of December 2010);



Executing the TF3 Activities Plan and providing sub-

deliverables and the final deliverable (to be completed by

the end of December 2013).

Recently, in the Netherlands, the Geo-Impuls joint industry

development program has been launched, in which some 30

large clients, contractors, engineering consultants, universities

and institutes do participate.

The target of the Geo-Impuls program is halving geotechnical

failures by 2015. Realizing the Geo-Impuls objective will save

the Dutch community at least several hundreds of millions

Euros per year.

A core activity of the Geo-Impuls program is developing and

applying sound geotechnical risk management procedures

within construction projects. New knowledge is developed and

particularly existing knowledge will be better used, in a risk-

driven way. This requires a thorough integration of

geotechnical risk management with project risk management.

It is suggested to use the results and lessons of the Geo-Impuls

program within TF3, and to compare these results and lessons

with those of similar programs, elsewhere in the world.

Deliverables

The anticipated sub-deliverables are at least one paper per year,

written by TF3 participants and to be presented at an

international symposium that covers geotechnical risk

management.

The final deliverable is a TF3 report, which presents practical

recommendations for combining and integrating discipline-

based geotechnical risk management with broader and more

generic project risk management in theory and practice. Using

this report by practitioners should contribute to more safety and

quality, lower costs and faster completion of all sorts of

construction projects, worldwide.

TC305 - MEGACITIES

GEOTECHNICAL INFRASTRUCTURE FOR MEGA CITIES

AND NEW CAPITALS

Chair: A. Negro

TERMS OF REFERENCE

The main goal of this technical committee is to contribute to the

general practice of those working in a Mega City scenario, to

gather and share their experience on foundations, tunnels,

excavations, earthquake engineering, slope stability, soft soils,

environmental geotechnics, and others. Mega Cities demand a

General Practitioner Geotechnical Engineer and requires the

need for gathering and collating previous experience to

encourage technical development. Having this in mind, the

objectives of TC305 for the period 2010-2013 are as follows.

1. To stimulate interaction between infrastructure geotechnical

engineers for megacities, new capitals and twin (sister) cities

1.1. At an international level

To promote a workshop during the 14

Asian

Regional Conference, Hong Kong, May 2011;

To promote organization of the Twin Cities

Geotechnical Seminars (basic planning in annex)

in 2012;

To promote a session or a workshop during the

next ICSMGE, Paris 2013;

To encourage and stream the preparation of papers

from TC305 members to the ISSMGE International

Journal of Geo-Engineering Case histories.

1.2. At a regional level

To organise regional workshops at the occasion of

large or challenging projects:

To encourage the active participation (papers,

lectures, workshops) of TC305 members at

regional conferences.

2. To gather and collate geotechnical information

To set up data and cartographic instrument specification;

To establish access to public data;

3. Interact with other TCs and organisations concerned by

Geotechnical Infrastructure for Mega Cities:

To establish or maintain contact with TCs having close

interests such as TC204 (Underground Construction in

Soft Ground), TC211 (Ground Improvement), TC212

(Deep Foundation), TC215 (Environmental Geotechnics).

To cooperate with Deep Foundation Institute during the

International Conference on Grouting and Deep Mixing,

15-18 February 2012, New Orleans, LA, United States.

ANNEX

TC MEGACITIES 305 - TWIN CITIES GEOTECHNICAL

SEMINARS.

Background:

it has been a tradition of the Sao Paulo branch of

the Brazilian Geotechnical Society (ABMS) to organize, every

ten to twenty years, a local seminar to gather and collate

summarized geotechnical and geological data related to Sao

Paulo City, conditioned mainly by sedimentary Paleocene stiff

and dense soils. Different contributors are invited to prepare

contributions, updating the knowledge on selected topics such

as local geology, hydro-geological conditions, soils micro-
