Key words – light-weight fill, gravel raft, settlements, numerical modelling Abstract The use of Mainmark’s Terefil as an alternative to reinforced gravel raft for liquefaction mitigation and to minimise total static settlements and foundation differential performance under the building loads over soft cohesive and loose…
. 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 This paper describes the geotechnical aspects of a collaborative seismic assessment and foundation strengthening design for an existing building in the Tauranga CBD. The reinforced concrete 6 storey high structure is supported on concrete piles founded on potentially liquefiable volcanic soils. Initial assessments concluded…
The new Gisborne Police Station building was built on a soft site occupied by a historical retail building. The façade of the historical building had to be retained, and the building demolished. Based on complex geotechnical investigations and consideration of various foundation options, Opus recommended that a piled…
The Amethyst hydro scheme aims to address the increasing demand for power in the area. It involves diverting water from the Amethyst Ravine through penstocks in a 1040 m tunnel to a powerhouse on the floodplain of the Wanganui River. The 3.5 x 3.5 m…
