Case study: Seismic foundation design for the new Wellington Children’s Hospital
Abstract The much-anticipated Wellington Children’s Hospital is currently under construction and scheduled to open in 2021. The project was made possible by a generous $50m donation from 2017 Wellingtonian of the Year Mark Dunajtschik. At the discretion of the benefactor and the Capital…

Statham Porirua City Council, Wellington. ABSTRACT Widespread slope instability occurred in the Porirua region after the…
First Wellington YGP Symposium
The 1st Wellington YGP symposium concluded successfully on 6 August 2019 and received lots of positive feedback. In total, 18 people from 11 different consultancies attended the symposium. The event was sponsored by Geotechnics, Engineering NZ and NZGS. 10 presentations on various geotechnical topics were…
Use of Small Unmanned Aerial Vehicles and Related Digital Data In Geotechnical and Natural Hazard Impact Assessments
This paper was originally published in Australian Geomechanics in September 2018 and is reproduced by permission of AGS ABSTRACT Unmanned Aerial Vehicles (UAVs or drones) facilitate data collection that allows rapid and enhanced geotechnical assessment of the risks associated with landslides, slopes and structures, during…
Effective Risk Management for Deep Foundations
On 21 November 2018 Dr. Martin Larisch presented to the Wellington Branch on the management of risk for deep foundations. His presentation slides are attached. Abstract The design of deep foundation elements like piles or permanent basement walls, require the comprehensive understanding of the required performance criteria…
SPECIAL FEATURE Characterisation of cyclic behaviour and liquefaction resistance of Wellington reclamations with gravelly soils
Gravelly soil (i.e. gravelly sands, sandy gravels, and uniform gravels) is generally recognized to have no or very low liquefaction potential. However, historically few case histories exist where observations of liquefied gravelly soils have been made, e.g. 1983 Borah Peak, Idaho earthquake (Youd et al….

Simplified procedures for estimating seismic slope displacements
Pseudostatic slope stability procedures can be employed in a straightforward manner, and thus, their use in engineering practice is appealing. The magnitude of the seismic coefficient that is applied to the potential sliding mass to represent the destabilizing effect of the earthquake shaking is a…
