ABSTRACT Within an 18 month period the Tairāwhiti region was hit with 3 heavy rainfall events and 2 cyclones. This resulted in over 5,200 recorded road faults across its 2,238 km network. The extent of the damage at any site ranged from minor culvert blockages…
ABSTRACT Trees in urban environments cool cities, capture carbon, and reduce stormwater runoff through enhanced initial losses. However, their root systems require uncompacted soil to grow, a requirement that is inconsistent with optimal pavement performance. To accommodate trees in roadways, carparks and pedestrian accessways, Citygreen…
Abstract The use of varied desktop reconnaissance tools allows for effective identification of locations that warrant specific attention to enhance field studies. This is illustrated by a mapping project for over 25,000 ha of mixed rural and urban land identified for potential future urban…
. ABSTRACT The Jeffreys water supply pump station comprises replacement of the earthquake-damaged 200m3 concrete suction tank with a new 500m3 tank. Ground conditions at the site predominately comprise interbedded alluvial silt and sand in the surficial 8.75m, underlain by dense sandy gravel. Surficial soils…
ABSTRACT The existing literature contains no shortage of attempts at defining ‘collapsible soils’, all largely focussed on outlining the often unique properties and conditions required for collapse settlement to take place. First recognised and studied by Jennings and Knight (1957), collapse settlement can, in…
ABSTRACT With the significant growth currently being experienced in the foundations market it has been recognized by many of the leading geotechnical contractors that collectively they lacked a voice and ability to shape the industry in terms of quality, Health and Safety and general best…
ABSTRACT Resilience of our built environment is important for our societies faced with a range of natural hazards, anthropogenic hazards and climate change. This requires a fundamental rethink of our traditional established and codified design approaches. A focus on resilience is required from early…
ABSTRACT System response using dynamic effective stress modelling can capture the holistic behaviour of a potentially liquefiable soil deposit, including interaction between different soil layers. Compared to a conventional liquefaction triggering analysis, a system response assessment can either predict more or less damage depending…

The past is key to the future; Collating historical cases of liquefaction to supplement liquefaction hazard assessments ABSTRACT Historical records indicate that consequential liquefaction has occurred during upwards of 11 earthquakes in New Zealand since European settlement and prior to 2010. Post-event…
