In 2022, NZGS with support from NHC began developing a series of Slope Stability Guidance (SSG) documents for use in New Zealand. Unit 1 – General Guidance is intended as an overarching document, supported by a series of additional units covering specific technical topics (Unit…
Unit 1 – General Guidance New Zealand is highly vulnerable to natural hazard risks, as evidenced by earthquakes and storm events over recent decades. Landslides form a significant part of the natural hazard spectrum in New Zealand and are more common here than many countries…
A clear and effective specification is an essential tool to help ensure that projects achieve the objectives desired by the client, geotechnical designer and contractor. While project-specific specifications can be useful in accurately describing the exact requirements for each project, they result in a steep…
This Specification sets out requirements for the construction of bored or driven pile types. This document is published in collaboration by the Structural Engineering Society New Zealand (SESOC) and the New Zealand Geotechnical Society (NZGS). This document supersedes the Auckland Structural Group publication “Piling Specification”…
These guidelines for Earthquake Geotechnical Engineering Practice in New Zealand were originated by a working group of the New Zealand Geotechnical Society. The idea for the working group came from a panel discussion ‘Geotechnical Seismic Design Standards’ which took place during the NZGS Biennial Symposium ‘Earthquakes and Urban…
The sequence of strong earthquakes in Canterbury in 2010 to 2011, most notably the devastating Mw 6.2 earthquake on 22 February 2011, the source of which was located within Christchurch, resulted in 185 fatalities and extensive damage to buildings and infrastructure. Liquefaction occurred on several…
