C. Santamaria, H. Wahab, F. Bruce & S. EdmondsBeca Limited, New Zealand ABSTRACT The Te Maunga Wastewater Treatment Plant required the design and construction of a new clarifier as part of the Tauranga City Council plan to provide a resilient treatment process path. This required…
M. C. McLean, B. O’LoughlinENGEO, Tauranga. ABSTRACT This paper presents a case study of a Ministry of Education (MoE) building project on potentially liquefiable dune sands at Mount Maunganui, Tauranga. It presents our methodology for assessing liquefaction vulnerability including triggering response and step change behaviour,…
J.R. FlynnWSP NZ Limited, Tauranga. R.P. OrenseUniversity of Auckland, New Zealand. ABSTRACT Thick layers of soft lacustrine silts are often encountered below a shallow surface crust around the southern margins of Lake Rotorua and can present challenges for engineering projects in the region due to…

ABSTRACT In the field of earthquake engineering, structural response studies address the inertial loading of the superstructure that results in tower lateral, rotational and torsional movements….
S. Anwar, G. Blakeley & Z. Rana AECOM, Auckland, New Zealand. ABSTRACT For any proposed development site, it is standard geotechnical practice to assess the foundation soils for their strength and load-bearing capacity. In seismically active regions, it is also customary to evaluate the liquefaction…
Thoughts on Auckland North Shore East Coast Bays Formation rock slope stability and engineering design from field investigation and laboratory test results Abstract As New Zealand’s largest city, Auckland faces various natural hazards, including landslides. The East Coast Bays Formation (ECBF) slopes along Auckland’s North…
Introduction Large earthquakes pose significant risk to life and livelihood in seismically active locations across the globe. Whilst it is widely accepted that earthquake events are responsible for significant economic loss and fatalities, the cascade of secondary hazards instigated by seismic events can be equally,…
