7th Conference – Montreal – 1997

7th International Conference – Montréal 1997: “Underground Space: Indoor Cities of Tomorrow”

Following the 6th conference held in Paris, in 1995, the City of Montréal had hosted the 7th meeting under the auspices of ACUUS, the international organisation that will co-ordinate all subsequent conferences in the series.This conference, “Underground Space: Indoor Cities of Tomorrow”, had focused on possible future partnerships and the interdisciplinary that must exist to create what are often colossal underground projects. Partnerships and interdisciplinary work are closely linked to the multiple facets involved in the construction of any underground project. They include: analysis, planning, financing, regulation, construction, technology, management, administration, promotion, marketing, maintenance, security, signage and even activity-planning. Four major themes were reviewed over the three main days of the conference: Partnership, Interdisciplinarity, Indoor Cities, and Technological Innovations.

Partnership workshops had examined urban planning teamwork and responsibility sharing between public- and private sector decision-makers involved in the underground development of our cities. Discussion had also focused on partnerships regarding all aspects of underground security, notably user safety, fire/crime prevention and response, communications, building security and underground construction codes. In addition, these working groups had addressed partnerships formed to build underground projects, rehabilitate infrastructures as well as develop signage and user communications.

The workshops on interdisciplinarity had explored progress made by underground experts, particularly studies on user behavior and perception of subterranean space. They had also looked at underground urban planning, the architecture and design of indoor spaces and the placement of interior passages. Legal and fiscal analysis, financial issues as well as economic and feasibility studies have been discussed.Indoor cities workshops had used case studies of existing projects in certain urban centers, such as subways, subterranean stations and pedestrian malls to analyze their impact on underground mobility, transportation, commercial activity and shopping malls as well as on the city as a whole and its citizens.The working sessions had bearings on specific technological innovations affecting underground construction as well as three-dimensional models of excavations and databases. Participants had discussed excavated structures, mastering of geological constraints, equipment, tunnels and new techniques in rebuilding infrastructures and public utilities.

The 7th ACUUS International Conference “Underground Space : Indoor Cities of Tomorrow” has been organized by the City of Montréal, in collaboration with the University of Montréal and under the auspices of the International Tunneling Association (AITES / ITA) which was the sponsor of the event. The Conference was also under the high patronage of UNESCO.

6th Conference – Paris – 1995

6th International Conference – Paris 1995 : “Underground Space and Urban Planning”

The 6th International Conference on ”Underground Space and Urban Planning” (EUS 95) held in Paris, Centre des Congrès de La Villette, from September 26 to 29 1995, symbolizes the renewal of a French tradition represented by the works of the “Groupe d’Etude du Centre Urbain Souterrain” (GECUS) founded in Paris in 1933. Its 6th International Congress was cancelled in 1975 because of the death of Edouard Utudjian, its leader.Uses of the underground are extremely various and variable according to continents, climates and cultures. But cities seem to be the place where they represent the greatest stakes, a controversial topic, a great specificity and major complexities. That is why the organizers of the Paris Conference have chosen to dedicate their Conference to Underground Space and Urban Planning.

More than 100 papers from nearly 20 countries (Canada, China, Finland, France, Hong-Kong, Hungary, Italy, Japan, Norway, The Netherlands, Poland, Romania, Russia, Spain, Sweden, United-Kingdom and USA) are presented in this document.Each workshop tries to connect technical approaches with humanistic ones in several fields which are of major interest for our cities: safety, ambiances, networks and transportation, architecture and planning, spatial and technical interfaces, patrimonia, investigation and surveying, city planning. All of them show a need for research and international comparison. All of them also point the fact that the study of underground space questions the roles and methods of planners and architects.That does not mean that we want the promotion of universal and systematic use of underground. The Paris Conference had many objectives: to raise the problems of the saturation of the cities, of the preservation of their patrimonia, of the need for urbanity and quality of their facilities. Therefore, the third dimension — i.e. depth — must be taken into account if only because it plays already a major role in the city.
