Short Course

COST Action TU 1405 – GABI Short Course

How to plan a successful thermoactive geostructure design?


Despite the significant number of operating thermo-active geostructures in Europe, the development of specific design rules and dimensioning approaches has been slow. Attempts to provide a set of recommendations for piles, diaphragm walls and tunnels subjected to temperature variations were carried out starting in 2005 in Switzerland, Germany, United Kingdom and France. However, most of this documentation provides only general indications and does not allow the adoption of this technology across Europe for a wider range of projects.

This short course, organised by the COST Action TU 1405 GABI (Geothermal Applications for building and infrastructures), aims to synthesize research and practice-based knowledge from across national and disciplinary boundaries in order develop a better understanding and more a widespread use of this technology.

The course will take place on Monday, September 24th, the day before the start of the Symposium. The required supplement to attend the short course varies depending on your registration type and period. Please see the registration fees below.

Target Audience

The course will be valuable for civil engineers and urban project managers who have no experience with thermoactive practices as well as for those who have been already involved in a project including thermoactive geostructures.

Course venue                                                                                                                                          EPFL, Lausanne, Switzerland

The short-course will take place at the Swiss Federal Institute of Technology in Lausanne (EPFL), in the Civil Engineering building (GC building). The room reserved for this event is the GC B1 10 (see plan view below).

The EPFL can be reached from the centre of Lausanne by metro via the line 1, direction Renens Gare from Lausanne Flon, whereas direction Lausanne Flon from Renens gare. The estimated time to arrive at the EPFL metro stop from either way is approximately 20 minutes. The room where the event will take place can be reached through a 5-minute walk from the metro station via either of the following ways highlighted in red.
