Online: Auckland Branch Christmas Symposium

This event will be held online as a series of short lunchtime talks each week in December.  Our aim with the event is to focus on topics directly relevant to the Auckland region. NZGS members are invited to submit abstracts for papers to be presented as part of the online symposium.

 

The event will kick off on Wednesday the 1st of December 2021 around lunch time. Each session will run for 1h 15m and will comprise either 3x standard presentations (15min) or 2x extended presentations (25min) with time for questions after each presentation..  Subsequent sessions will be held on the 8th, 15th and 22nd of December.

 

If you have something short to present that would be of interest, please submit a short abstract (<250 words) to the organising team on auckland@nzgs.org by 12th November.

NZGS AGM + Presentation

New Zealand Geotechnical Society AGM & Presentation: As a result of the extended lockdown in Auckland we have decided to move the Annual General Meeting online and set the date as 27 September. It will take place at 12:00pm immediately before what is set to be a fascinating presentation by Sjoerd Van Ballegooy about modelling the impacts of liquefaction on the New Zealand residential building portfolio. You will be able to use the same link for both the AGM and the subsequent presentation.

Please register using the link on this page.

Further information, including the agenda and AGM papers, will be circulated shortly

Online Webinar: Let the terrain do the talking – Understanding Northland Landscapes from Aerial Photos and LiDAR Terrain Models

Presented by David Buxton, Geotechnical Engineer, Northland Geotechnical Specialists

Register free HERE

The presentation will comprise review and interpretation of aerial photo stereopair red/blue anaglyphs and LiDAR terrain models, with various overlays, for a number of sites around Northland. The presentation will highlight how interpretation of the terrain can inform our engineering decision making, and why it is particularly important in complex terrain. Best of all, both the data and software are free and readily available to all.

To view the aerial photo stereopair anaglyphs in the presentation you will need a pair of red/blue 3D glasses. For a free pair, please email david@northlandgeotech.co.nz. Alternatively, they can be cheaply purchased online (try wish.com, search “Red Blue 3D Glasses”, or they are also sometimes available on Trademe).

The presentation will be followed by a chance for questions/discussions.

David Buxton is a geotechnical engineer and has been Northland based for 5 years prior to which he worked for T+T in Auckland for 10 years.

NZGS Climate Change Symposium

The New Zealand Geotechnical Society in partnership with Engineering New Zealand, The Sustainability Society and MBIE will host a symposium to discuss the role of geotechnical engineers in climate change.

The symposium will engage the geotechnical industry in New Zealand and start discussions on how our industry can reach the carbon emission goals set by the New Zealand government. What does it mean for the geotechnical industry in New Zealand? Where do we need to stretch, collaborate and re-invent ourselves to meet the targets? Regardless if you work as a consultant, contractor, academic or policy maker, we are looking for a broad range of different opinions as this topic is important for all of us and collaboration, innovation and transformation are critical to start the process.

We hope to spark your interest and stimulate many constructive discussions about this topic and we want to hear different opinions and approaches how to overcome some of the current barriers. Collaboration is the key to reach these targets and help building a more sustainable future.

We are delighted to invite you to submit a presentation abstract and to register your attendance. Presentations will be short (10-15 mins) and we are specifically seeking presentations around the following topics:

  • Innovation
  • Challenges
  • Tools and techniques
    • adaptation, transition and mitigation
    • overcoming barriers to climate ready project

We hope to hear from you with an abstract and to see you in November for this inaugural symposium.

The role of a peer reviewer in geotechnical design – EVENT POSTPONED

EVENT POSTPONED due to community COVID case in Auckland

Join the New Zealand Geotechnical Society in their upcoming panel discussion – The role of a peer reviewer in geotechnical design.

Details and Registration HERE

This in-person panel discussion on the role of a peer reviewer in geotechnical design brings together panellists comprising technical directors/principals with extensive experience on the consulting, contracting and client sides.

Presenters: Andrew Campbell, Geoff Farquhar, Martin Larisch, Robert Hillier & Ross Roberts

The event will last approximately an hour and will comprise an introductory talk on the responsibilites and liabilities of a peer reviewer followed by short talks by each panellist based on their experience. The event will conclude with a Q&A session.

Please submit a maximum of three questions that you’d like to ask the panellists via the comments section on the registration form.

Free Webinar: The (R)Evolution of Monitoring

Presented by John King and Ryan Milligan (Geotechnics)

As digitisation picks up speed within the industry, connecting engineers to their data in a timely manner is becoming increasingly important. John and Ryan would like to share some of their lessons and experiences from the past as well as predictions for the future.

Equipping you with the knowledge you need to make the most of your data, sensors and monitoring and to enable you to deliver a better, safer and more sustainable service to your clients.

John King and Ryan Milligan have been intimately involved with Geotechnical instrumentation for their entire careers at Geotechnics. With combined experience exceeding 20 years, they have gathered some interesting insights along the way.

Liquefaction Assessment of Natural Pumiceous Deposits

Presented by Dr Rolando Orense
Associate Professor, University of Auckland

Pumice-rich soils are often encountered in many engineering projects and their geotechnical characterisation is very important. Due to the highly crushable nature of the pumice sand components, the applicability of current empirical correlations which have been derived from hard-grained sands needs investigation.

The presentation focuses on the findings of the research projects conducted at the University of Auckland (with the support of EQC, NHRP and QuakeCoRE) to characterize the pumice sand properties and the dynamic and liquefaction characteristics of natural pumiceous deposits through field testing, high- quality soil sampling and laboratory testing. Moreover, the procedure developed to quantify the pumice contents of soil samples based on the crushability feature of the materials is presented.

Finally, based on the results obtained to date, an empirical chart correlating shear wave velocity and cyclic resistance as a function of the soil’s pumice contents is proposed.

Webinar: Soil Improvement Solutions to Increase Slope Stability under Seismic Conditions – Design and Techniques

 

Free  Registration HERE 

 

Presented by 

Jason Redgers, Dr Serhat Baycan & Dr Philipp Schober from BAUER Spezialtiefbau GmbH

 

 

The stability of slopes, specially when consisting of soft cohesive soils or liquefiable granular material, can be compromised during seismic event and lead to major failures. Lateral spreading or sliding failure can be induced by reduced shear strength and horizontal acceleration during a seismic event. Soil improvement techniques can be used to increase the shear strength and mitigate the risk of liquefaction and lateral spreading. Reinforcement and compaction techniques, alone or in combination, are most suitable to overcome slope stability problems. Advanced design, using 3D-FE analysis can be further applied to provide technically and commercially optimized soil improvement solutions.
