ATS 2020+1 New Zealand hub
The Australasian Tunnelling Conference (ATS2020+1) is the premier tunnelling industry conference in Australasia. The organising committee are celebrating 50 years of tunnelling conferences in the region with a theme of innovation to continue the knowledge sharing and peer-to-peer networking tradition that only happens at conferences. The NZTS are pleased to be able to support a long tradition of regional tunnelling conferences and look forward to seeing you at Eden Park on the 11th and 12th of May.

The Hallandsås Tunnel Project was a major railway infrastructural project in Sweden associated to a long history. It was opened to the public end of 2015. In 2004, the third attempt to complete the construction of the two tunnels started, based on an alternative technical solution involving excavation with a 10.6m diameter dual mode hard rock Mix-Shield TBM, which was a complex machine capable of being operated in open mode, closed mode (slurry) up to 13 bars and to undertake systematic pre-excavation grouting. The large variations in the characteristics of the rock mass, the high water pressure (up to 13 bars) and the presence of long water bearing zones made the ground conditions definitively difficult. The most significant difficulty along the tunnel route was the Mölleback zone, an extensive fault zone, about 320m in length. A part of this fault was subject to an advanced ground freezing operation of 125m in length in order to permit TBM excavation, the remaining part being treated by conventional cement grouting.
Francois Dudouit has over 33 years of construction experience, gained on major railway underground projects in France, Denmark, Hong Kong, Nederland and Sweden. His experience includes TBM excavation in challenging soft ground and hard rock, with pressure up to 13 bars. Between 2003 and 2012, he was responsible for the construction on the Hallandsås Tunnel Project. He is presently Project Director of Link Alliance for City Rail Link Contract C3.

The NZTS is pleased to facilitate a 3 day short course presented by Dr Donald Lamont, a leading authority in the world of tunnelling health and safety; advocate and practitioner.
The course is aimed at senior practitioners with responsibility for health and safety risk management of underground construction and covers planning, design, construction and operational aspects, roles and responsibilities. The principal focus is the health and safety aspects of tunnel construction.
The interactive course will cover:
- Guidance sources
- Contribution of client and designer
- Occupational health matters relevant to tunnelling
- Welfare in tunnels
- Mechanised tunnelling safety
- Conventional tunnelling safety
- BS6164, EN 16191
- Observational Methods
- Occupational Health
- Fire in tunnels
- Atmospheric contamination
- Compressed Air
- Access/Egress/Transport in Tunnels
- Emergency Preparedness
- Personal Safety
The cost of the course is $1800 inc. GST and is worth 18 hours of CPD. All course materials, food and refreshments will be provided.
Numbers of attendees are limited, so register today to confirm your place on this unique course. Please send any enquiries to me at email@example.com

Rafael Sierra Ballen has worked as a construction manager for over thirty years in South America, the Middle East, Asia, Australia and New Zealand for major civil engineering projects as a tunnel design manager and a tunnel construction manager.
Topics Covered During this Presentation
From a standing start, following the largest ever recorded earthquake in New Zealand, a highly committed collaborative team, assessed the damage across twenty tunnels, designed the repairs in view of future resilience, and built a construction capability that delivered the works safely and on budget. Works trains were running again within 7 months, and commercial services within 10 months. In doing so, we reconnected communities at the top of New Zealand’s South Island.
Rafa will describe the logistical and technical challenges of refurbishing the rail tunnels in the context of the natural terrain hazards and landslides informed by his experiences of driving the quality and safety outcomes achieved.
