The New Zealand Geotechnical Society and the 2031 ISRM Congress
The NZGS is an active and vibrant society, with 1550 members, of which 300 are affiliated to ISRM. It offers a wide range of resources to its members, including technical guidelines, publications, in person short courses and webinars, to support professional development. NZGS plays an important role in connecting the industry to academia, with university professors and researchers actively involved in the management of the Society and in organising and delivering our events.
The Society participates in wider-sector conferences, projects, and advocacy for the advancement of the professional practice. In 2021, NZGS issued the final version of the Geotechnical Earthquake Engineering Practice Series in conjunction with the Ministry of Business Innovation and Employment.
These documents benchmark the geotechnical earthquake practice in New Zealand and attracted the international attention. The NZGS was very proud to be selected Outstanding Member Society of the ISSMGE for the period 2013 – 2017.
The structure of the Society includes regional branches and specialized groups, catering to specific interests like sustainability and young professionals. Additionally, NZGS hosts regular meetings and publishes a biannual journal to keep members informed. Through these initiatives, NZGS promotes the growth of the geotechnical field and supports members in achieving excellence.
The NZGS is aiming to increase the interest of its members and especially of the young professionals in rock mechanics and rock engineering and, in collaboration with the Australian Geomechanics Society (AGS), raise the profile and impact of ISRM in Australasia. Hosting the international congress of 2031 in New Zealand offers a unique opportunity towards achieving this goal.
We propose to combine the ISRM Congress 2031 with our four-yearly NZGS National Geotechnical Symposium. This offers significant advantages to the ISRM Congress, as we will leverage the experience of organising a well-established and popular local event, while attracting more local geotechnical professionals to actively participate in organising, delivering and attending the ISRM Congress.
Congress theme
Our recommended congress theme is:
“Shaping a sustainable future in rock mechanics and rock engineering”
This is inspired by the current environmental, economic, and social challenges that the world is facing. We aim to explore how the rock mechanics and rock engineering field can contribute addressing these worldwide issues by integrating innovative practices and technologies. Aligned to the main theme, the following topics will receive particular attention:
- Low-carbon exploration with focus on reducing carbon emissions during mining and construction processes.
- Geothermal energy utilization, enhancing the design and construction of geothermal systems to efficiently extract and utilize geothermal energy.
- Exploring sustainable design and construction techniques • Promoting non-destructive investigation techniques to increase carbon efficiency and improve accuracy and efficiency of engineering geological models.
- Promoting education and training that emphasize sustainable practices in rock mechanics and engineering and encourage interdisciplinary approaches that combine engineering, environmental science, and economics.
Developed around the key areas of the main theme, we envisage that the following streams will be included in the programme of the 2031 congress:
- Rock mass classification and properties
- Field investigation
- Laboratory testing and experimental studies
- Landscape processes, and geological models
- Advances in digitisation, automation and data management
- Monitoring for rock engineering applications
- Earthquake engineering and rock dynamics
- Analytical methods and advances in numerical modelling techniques
- Rock slope design and risk-based approaches
- Open pit and underground mining
- Tunnel design and construction
- Hydropower projects and dams
- Deep energy resource recovery, storage and disposal
- Foundations in rock
- Complex rock engineering projects
- Adapting rock engineering to a changing climate
- Sustainable rock engineering design
- Hazard, risk and safety evaluation
- Current and future status of education of rock mechanics
- Heritage structures preservation
- Early Career Forum (young researchers)
At the congress, we are planning to host multiple events for young professionals and early career researchers. These events will include the Early Career Forum and the Rock Bowl.
Congress venue and location
The Congress venue will be the Te Pae Christchurch Convention Centre, which is located right in the heart of central Christchurch. The centre has been open for 2 ½ years and has already hosted nearly 500 events in its first two years of operation. The main auditorium seats 1,400 people (or can be divided to seat 700), there are up to 24 meeting spaces for concurrent sessions, workshops and commission meetings. The exhibition halls encompass up to 3,300sqm of space to accommodate poster sessions, trade displays and the welcome reception. The centre can also stage the Council meeting and congress dinner with the awards ceremony.
Te Pae Christchurch is within easy walking distance of close to 3,000 accommodation rooms of various styles and sizes, and all key city highlights including retail, hospitality and entertainment. It also overlooks the green spaces of Victoria Square and the Avon River, giving visiting delegates an exceptional experience. The venue has also recently achieved Toitū net carbon zero status – we believe this is the first convention centre in the world to achieve this status. More info on the venue is provided on page 19 of this proposal.
Christchurch is home to the University of Canterbury, a world-renowned university with close ties to NZGS.
Christchurch is situated on the northern flank of the Banks Peninsula, a region formed by successive volcanic eruptions that created a striking landscape of volcanic hills and craters
with interesting rock mechanical properties. In addition to the city itself, the Christchurch region offers great opportunities for rock mechanics and rock engineering case studies:
- The 2016 Mw 7.8 Kaikōura Earthquake caused the rupture of 21 faults and triggered more than 29,000 landslides across the Northwest part of the South Island, which severely damaged the transport infrastructure north of Christchurch, as far as Picton. The surroundings of the coastal town of Kaikōura, located just 2.5 hours’ drive from the city, offers extensive rock mechanics and rock engineering examples of slope stabilisation and landslide mitigation.
- The Southern Alps, located to the west of Christchurch, feature a variety of geological and geomorphological landscapes, including the 650 km-long Alpine Fault that transects the South Island. Two notable glaciers Franz Josef Glacier and Fox Glacier are descending from the Southern Alps into lush, temperate rainforests, creating a striking contrast between ice and greenery.
Christchurch’s unique geographical location with its rich geological and geotechnical history provide a unique and valuable context for the technical tours of the 2031 congress.
Christchurch is located in the heart of New Zealand’s stunning South Island – meaning there are wonderful opportunities for international attendees to explore our beautiful country pre – or post-conference, all easily accessible from Christchurch.
