We are pleased to announce that our bid for the ITA WTC 2029 has been successful.

Thank you to everyone involved for their support and trust.

75th GEOMECHANIK COLLOQUIUM & 15th Austrian Tunnel Day 2026

The 75^th GEOMECHANIK COLLOQUIUM 2026 will take place from October 8-9, 2026, and will be dedicated to Prof. Gerhard Seeber.

We look forward to receiving your contributions on the following topics:

Brenner Base Tunnel: Experience to date
Sustainability in geotechnical engineering?
Monitoring during construction and operation
Infrastructure: Operation, maintenance, renewal

Prior to the Colloquium, the 15^th Austrian Tunnel Day is scheduled on October 07^th, 2026, with following topics:

Power plant constructions
International construction contracts
International major projects
New regulations
Digitalization in tunnelling

Geomechanics Colloquium 2024

ICSMGE 2026, Vienna

The Austrian Geotechnical Society and the Austrian Society for Geomechanics are proud to jointly celebrate the 100^th anniversary of this milestone in geotechnical engineering.

“Where it all began” is therefore the motto of the 21^st International Conference on Soil Mechanics and Geotechnical Engineering (ICSMGE), which will take place in Vienna in June 2026.

Take the opportunity to present your company as an exhibitor and/or sponsor!

The Austrian Society for Geomechanics (OeGG)

A group of Austrian experts started in the fifties of the 20th century to deal with rock engineering. This group was also called Salzburg Circle. As early as 1951 Leopold Müller organized a Colloquium about rock engineering and technological questions in Salzburg.

In 1962 the International Society for Rock Mechanics (ISRM) was founded in Salzburg. Leopold Müller was the first president of the ISRM. The Austrian Society for Geomechanics (OeGG) was founded in 1968 as national group of the ISRM.

The aims of the OeGG are to promote scientific research in all fields of geological and geotechnical engineering with all those involved in geotechnical research, construction, administration, improve geotechnical design and construction methods, and to publish scientific papers and guidelines.

The society is divided into individual technical sections, each dealing with questions related to geology, foundation and rock engineering, soil and rock mechanics, as well as tunnelling.

Presently, the OeGG has approximately 585 regular members and 36 supporting members.

The Austrian Society for Geomechanics is organizer and co-organizer of Colloquiums, Conferences, Seminars and Workshops.

The OeGG's hallmark event is the annual Geomechanics Colloquium in Salzburg.

This colloquium is one of the world's largest annual conference on geotechnics, consistently with more than 800 participants. It developed to a meeting place of researchers, designers, contractors, owners and manufacturers.

The interdisciplinary nature of the Colloquium represents the vision of the OeGG. In addition to technical issues, contractual and economical aspects are discussed.

Seminars and workshops on special technical topics are organized the day before the Colloquium, which have seen increasing attendance over the past several years.

Every second year, the OeGG co-organizes the Austrian Tunnel Day. In addition, the OeGG supports events organized by the Graz University of Technology, Vienna University of Technology and Leoben University of Mining. All these events are designed to fulfill the objective of the society to support the exchange of knowledge.
